CLASSIC WOODEN BOAT RIVER CRUISE – TRIP REPORT
Fridays Classic woodys cruise to the waterfront Riverhead Tavern for lunch was a grand day afloat, 13 classic wooden craft made the journey up the upper reaches of the Waitemata Harbour to the historic tavern. It was extra special with several first-timers making the trip.
We were blessed with the weather and also having just one of the tourist ferries making the trip on the day, which allowed us to berth a lot of the boat on the jetty.

Special mention to the 7 classic launch skippers and partners that came by water taxi (MY GIRL) – Cam Malcolm (Connie V), Rodger Moore (ex Te Hauraki), Jason Davies (Lucinda), and those via car – Ian Gavin (Florance Dawn), Matt Cooper (Korawai) and John Chambers (Ngarunui), Murray Deeble ( Waikiore) combined with the 13 boats on the water we had crews from 20 classic craft present on the day. Very happy with that turn out.

True to form, the tavern and its staff extended their usual warm hospitality.

WAIHEKE CLASSIC WOODY BOATS

These days it seems that when it comes to classic wooden boat locations, the ‘new black’ is the Bay of Islands. 

So I’m very happy to report that two woodys have found new owners / homes at Waiheke Island, Auckland.

Recently we helped find a new owner for the 28’ John Brooke designed, Walter Deeming built launch –  SEAFARER  and she is now moored at the island. Photos above of the delivery voyage, the bacon and egg pie is a masterpiece, made by the new owner’s father. More photos of the launch here https://waitematawoodys.com/2025/04/09/classic-wooden-launch-seafarer-a-peek-down-below-4sale/

Also the 38’ RAIRA (photo above) built in 1918 by McLeod Bros. Devonport, has a new owner and will be remaining at the island. More photos here https://waitematawoodys.com/2025/04/29/raira-a-peek-down-below-4sale/

GRAYMARINE 6CYL 4 STROKE MARINE DIESEL ENGINES 

GRAYMARINE 6CYL 4 STROKE MARINE DIESEL ENGINES 

THETIS with her twin Graymarine 4 stroke 6cyl diesel engines  

These are a very rare model of the Graymarine range, that was originally produced in WWII for the US military. All Graymarine diesel engines for general and normal marine use worldwide, including NZ, are based on the GM Detroit two-stroke engine, marinized by Graymarine. I believe the THETIS engines were the only two that ever came to NZ and were specially imported by Jack Butland for his 1955 Lane Motorboat built launch, THETIS. Here is a copy of previous comments I made regarding these engines, on Woodys.

26-04-2018 WW UPDATE

“Ken Ricketts reports that having recently spoken with Thetis’s owner that the 2 in line, 6 cyl, 4-cycle, 120hp Gray Marine engines, installed in 1960 (still there today) are a very rare model & type. They were manufactured during WWII for the American forces & could possibly be the only 2 in NZ. The owner believes her original owner Jack Butland in the later 1950’s probably reconditioned, & war surplus imported them.”

BELOW IS A REPRINT OF THE HERCULES SETION IN PART 2 WITH ADDED TEXT I HAVE TAKEN THE LIBERTY OF REPRINTING IN THE CIRCS. 

HERCULES 6 CYL c100HP DIESEL ENGINE AS FITTED TO THE FAYE

HERCULES 275 HP DIESEL ENGINE, SIMIALAR TO THAT PREVIOUSLY IN THE RAKANOA 

FAYE WITH HER 6 CYL HERCULES HOME MARINISED DIESEL ENGIINE

RAKANOA WITH HER  275 HP 6 CYL. MARINE/HOME MARINISED DIESEL ENGINE

Hercules was a manufacturer and supplier of a large number of basic engines to many marine engine companies for marinization by each company to its own specifications. This included names such as Kermath, Chrysler, Graymarine, Scripps, Chris Craft, and many more. However, engines sold under the Hercules name, based on my research, are comparatively very small compared to their total manufactured units.

There are two boats I know of in New Zealand that have engines both labelled under the Hercules name and are diesel engines. One is the FAYE, which is equipped with a home-marinized C100P 6-cylinder Hercules diesel engine. This engine replaced her original Willys Jeep petrol engine when she was about 4 or 5 years old. FAYE’s details are noted in her Willys Jeep listing in part 2 of this post.  

The other is the beautiful 56-foot RAKANOA, built in 1946–47, which had a 6-cylinder 250HP Hercules diesel fitted after she had been in the water for one year. This engine replaced her original GM Detroit 165HP 6-71 diesel.  

Her original owner, Stan Parker, was a brilliant engineer and owned a very large precision engineering business. 

I am not sure if the Hercules engine was factory or home-marinized, as he would certainly have had the ability and equipment to do this. Stan, the original owner of RAKANOA, owned a large heavy engineering factory in Auckland. This business passed to Ross when his father passed away in 1961. RAKANOA retained this engine until 1981. Ross told me, after he inherited her many years ago, that they had always had trouble starting the Hercules engine, especially when hot. Many years after he inherited her, he eventually replaced the Hercules with a Gardner 6L3 diesel engine, which she still has to this day.

The Hercules engine was fitted because original owner Stan P., could not tolerate the very loud high pitched geartrain noise of the Rootes blower, combined with a loudish exhaust noise, she had with the G.M. Detroit

Unfortunately, I have not been able to find on research to date, any images of the 250 HP marinised version of the Hercules engine, however I have found what may be an unmarinised version, of RAKANOA’s engine.

HAIMONA IN HER PLEASSURE CRAFT GARB WITH HER 2 RUSTON HORNSBY DIESEL 200HP ENGINES, ON THE KAIPARA HARBOUR

MANOWAI IN HER RUSTON HORNSBY DIESEL ERA, AT HERALD ISLAND 

There are only two of these I know of in New Zealand in pleasure boats. One was in the 32 ft MANOWAI, during the second part of Claude Atherton’s era, from 1949 until at least the 1960s; it was a twin-cylinder version of the engines. 

The other boat was HAIMONA, formerly HDML MANGA, which was based in the Kaipara Harbour. Eventually, after a few years there, the only slip she was able to use for maintenance became unavailable, and she deteriorated badly before being destroyed by her last owners. 

When they bought her, a massive coaming structure was added, and they also replaced her original Foden engines with twin 200 HP 6-cylinder Ruston Hornsby diesels, which they removed prior to dismantling her.

FORD FALCON 4.1 LTRE 6 CYL. PETROL ENGINES

FORD FALCON 4.1 LTRE 6 CYL. PETROL MARINE ENGINE

VALSAN CHRISTMAS 1948 IN HER PRE-FORD-FALCON, PETROL ENGINE ERA

The 1938 Roy Lidgard-built VALSAN was bought by Arnold Baldwin around 1947, complete with her original engines, which were 2 x 100 hp flathead Graymarine petrol engines. He owned her for many years, and the time eventually came, after many of those years, when they had to be replaced, around 1970.

I was amazed that he chose 2 x Ford Falcon 4.1 L petrol engines as replacements, as these were engines usually associated with small day boats or runabouts, often equipped with stern drives or jet units. There were a total number of such engines unknown to me, and she is still the only launch I have ever heard of with these engines.

Things have, of course, moved on since then, and the last I heard, she had 2 x 4-cylinder Mitsubishi diesel engines post 2000.

ALIBI’s 2 “STERN POWER” STERN DRIVE UNITS, & NOTE BOTH ENGINES EXHAUST OUT THE SAME SIDE AT THE TUCK

As readers of this series may recall, ALIBI made a cameo appearance in part 2 when I was seeking information related to her sistership, which I now know is or was called CRESCENDO, seen below on launching day, as I have seen the two V8 Chrysler-branded diesels CRESCENDO had when new. 

Thanks to the input of others, I have now also discovered that these engines were manufactured by another company, and simply sold under the Chrysler label, which seems to me to be a continuation of Tony Mason’s apparent tendency to use engines with the Chrysler label, as in ALIBI. 

However, since the previous cameo appearance of ALIBI, I now have full details of her engines, thanks to a lady named Juliet Hindman, who is very knowledgeable about the Mason Clipper range of boats. 

Her family has owned one of the two only 33-foot versions of the Mason Clipper, and she has now contacted me. 

As a result, and with the information she has provided, ALIBI now definitely falls into the “Unique” class of engines category, as specified above, as far as I’m concerned, and she now has her place in the group in her own right. 

ALIBI’S two CHRYSLER-MITSUBISHI CN-55TI DIESEL ENGINES, producing 200 HP at 3150 RPM, are driven through Warner gearboxes to “Stern Power” make, cream-painted counter-rotating outdrives. While the engines and gearboxes are both left-handed with a 1-to-1 ratio, outward turning counter-rotation of the propellers has been achieved by the gearing system in the stern drive units, which are also acting as reduction gears with a 1.5-to-1 ratio, driving Volvo 16 x 17-inch propellers.

I feel the engine-to-stern-drive setup with these engines, is superior to many others, in that the engines are obviously primarily produced for conventional drives, having the gearboxes attached to and as part of the engines, but can still be used either way, for stern drive units, or conventional drives, with the stern drives simply providing the drive to the propellers. 

Many manufacturers combine the gearbox and stern drive into one unit, which makes them much more complex and quite possibly much more expensive to maintain.

Additionally, the combination drive/gearbox units are often very “clunky” and jerky when selecting forward or reverse, whereas there would not be this clunk with the smoothness of hydraulic engine-attached gearboxes.

I have spent a great deal of time, trying to source a good clear image of these engines, but they seem to have disappeared from historical public databases, and the only image I have been able to source, is of ALIBI’S own engines installed in her.

It is, however, wonderful that she still has these original engines after all these years since she was built in the later 1970s. A great testimony to Mitsubishi. Here are her details as received from Juliet H.:

“Released in 1979, the Clipper 42 was 12.8m x 3.7m with a draft of 900mm and, fully laden, displaced around 9 tonnes. Alibi was the prototype, built with a sandwich construction of strip-planked cedar, fiberglass on both sides. A mould was taken off the prototype so that all future boats could be full GRP with a balsa core. However, Crescendo was the only boat ever pulled from the mould.” 

I would recommend that readers revisit ALIBI’S cameo appearance in part 2 of the series to see some wonderful images of her exquisite finishing and interior.

A final note re CRESCENDO.   – She has been seen reasonably recently, in the South Island, I have been told, so any further help with information about her in any way, would be much appreciated. 

LISTER MARINE DIESEL ENGINES

I had considered including LISTER MARINE DIESEL ENGINES in the group, however, there are quite a good number of these engines that are or have been in use in NZ., in many work boats, fishing boats, tugs, & a few pleasure craft, & in the end I decided they fell just outside the scope of what I was about, so will just make a general mention of them, with a few images of the odd pleasure craft, all of which had these engines installed by Roy L.

Roy Lidgard used quite a number of them in various types of craft, the 1940s & 1950s, mostly 4 cylinder, & also had a 4cyl version of the Lister Diesel driving the Smeltinghouse Bay Kawau island sawmill, he set up & ran on his property, in the later 1940s & 50s, the remains of which are still there today. 

As just a brief mention, he installed Lister diesels, in the ROSE, (2 CYL) (later LA ROSA) Clive Power’s WAINUNU, (4 CYL) & TAWHIRI, a lovely sedan topper R Lidgard built in the mid/later 1940s (4 cyl)

EPILOG:

Well, readers, we have come to the end of this seven-part journey, and I can only say that for me, it has been a wonderful ride, to share with all of you who have taken the time to share the ride with me, and to follow the seven parts of what I’ve learned throughout my lifetime.

So often, you know as much, if not more, than I do. While some may have learned a little from me, I have, in turn, learned much from many of you, as we have shared this journey together, & I thank you all, for the opportunity to gain this new knowledge from you. 

I especially want to express my humility and gratitude, for the kind words of thanks and appreciation, in some of your comments directed towards me personally.

I have done this most of all, to encourage us all, to share and record publicly, what we know about our New Zealand-based boats, with each other, and most importantly, to provide a public record, for the benefit of the boaties of the future. Those who will come after we old wrinklies have all gone, & will become the stewards of tomorrow. As a result of what we all write now, they will hopefully have the chance to understand what has gone before in all or many aspects of what will become their boats, the majority of which will surely live on long after we are not here.

The MANUNUI was built for Percy Colebrook in 1939 by Bill Couldrey and had a medium / slow revving 6 cylinder 55 hp Benz Diesel engine fitted when built, which she retained until 1963 when it was replaced by a 100 hp Perkins Diesel. 

CRUSADER V8 MARINE PETROL ENGINES

TWIN CRUSADER ORIGINAL V8 PETROL ENGINES HAVING SERVICING, FROM THE RIVA TRITONE “LOLA,” WHICH ARE STILL IN HER TODAY. 

Crusader engines, while major marine engine suppliers in America and other countries, have only made a cameo appearance in New Zealand, with only a handful of these lovely engines in use here, as far as I can ascertain.

Overview: The only craft I personally know of for certain is the stunning 1962 Italian-built Riva Tritone, LOLA.

However, WINSOME II may have had one, back around the 1950s when owned by Andy Donovan. I know her previous Chrysler 8-cylinder inline engine was replaced around that time by a V8, that was either a Crusader, Chris-Craft, or Flagship. However, the memory banks have failed me, making it impossible to determine which of the three it is, so come on, you WINSOME II experts, help me out here!

In the 1960s, Crusader Marine Engines was a prominent brand worldwide, providing inboard power for many boats, particularly cruisers and sport fishermen. They were known for their premium quality and reliability, used by leading boat manufacturers like Chris-Craft. 

Crusader engines were based on standard automotive engines, but were marinized for marine use, with many of them based on Ford engines, and later with Hercules and Chrysler base units.

LOLA WITH HER 2 X CRUSADER 270HP PETROL ENGINES 

LOLA, the 1962 Italian-built Riva Tritone Aperto, has a LOA of 27 ft and is one of only 15 in the world. 

It is believed to be the only original Riva in New Zealand and a stunning example of boat restoration, all completed in NZ. Only 3,000 Rivas were built between 1950 and 1966, and she still has her original engines. She lives, or did live, in her own, purpose built, fully air conditioned boat shed, on the banks of the Marlborough Sounds.

WINSOME II – MAY HAVE HAD A CRUSADER V8 PETROL ENGINE IN THE 1950s /60s ERA – POSSIBLE ALTERNATIVES ARE FLAGSHIP & CHRIS CRAFT 

CHRIS CRAFT PETROL ENGINES.

CHRIS CRAFT 1950s 6 CYL FLATHEAD PETROL 135hp ENGINE SIMILAR TO THAT IN THE GLENIFFER IN THE 1950s

These are another brand of engine that is sold in huge numbers worldwide, particularly in America, where all genuine Chris-Craft boats are built. However, they have only made a cameo appearance in New Zealand, with most of them coming here in imported Chris-Craft boats.

There are a few New Zealand-built boats that have or have had them. I have only ever seen a petrol version, although naturally, they do produce diesel engines in their lineup. All the engines they produce are based on other major engine manufacturers’ base engine blocks and are marinized by them. Hercules is a major engine block supplier to them.

GLENIFFER WITH HER CHRISCRAFT 6 CYL FLAT HEAD PETROL ENGINE RUNNING ON KEROSENE IN THE 1950s – OWNER PERCY JENNINGS IS AT THE HELM.

Input copied from previous post, ex Harold Kidd.  – “Trevor Davis sold GLENIFER to P J Jennings of Paeroa in 1937 and he sold her to George Manktelow of Paeroa in about 1959. The Gleniffer was replaced by a 6-cyl Chris Craft (Hercules block) during the 50s, converted to run on power kerosene with a Model A Ford Zenith carb.”

FLAGSHIP MARINE ENGINES

FLAGSHIP 1958 250HP V8 PETROL MARINE ENGINE – BASED ON A CHEV BLOCK

There were a number of these engines that found their way to NZ in the 1950s/60s era and this is one of the possibilities for the V8 engine that was installed in the WINSOME II in that era by Andy Donovan who may also have had an agency for them, around that time.

CLASSIC KAURI LAUNCH. – PUTIKI

CLASSIC KAURI LAUNCH. – PUTIKI

Todays classic wooden launch has  recently popped up on tme (thanks Ian McDonald). Terrible listing, eg so few details but putting that aside with an $8k asking price, PUTIKI could be a great project for the winter. Some boatyards would charge you more than $8k to make that butterfly hatch.

What we know is she is 32’ in length, kauri planked (but sadly f/gased – but maybe thats keeping her a float) and powered by a 80hp 4 cyl. Ford Lees diesel engine. 

Home is currently Kerikeri.

The boat and name is unknown to WW so keen to learn more on her past .

06-05-2025 INPUT ex STEV LITTIN – Putiki was owned by my father Albert Littin while in Port Albert from about 2003 till 2010 and then moved to One Tree Point, Whangarei till sold about 5 years ago to Totara North. Current engine was rebuilt and fitted by Dad to replace the engine that broke a crankshaft and self destructed while fishing on the Kaipara.

Built 1907-10 we believe in Mangawhai. Dad has a picture from I think the 1940’s-50’s taken on the Mahurangi River.

LINDA, AT CHRISTMAS 1948, TAKEN IN SCHOOLHOUSE BAY, KAWAU ISLAND, JUST AFTER HER LOEW-KNIGHT PETROL ENGINE HAD BEEN REPLACED, WITH HER GM DETROIT 165HP MARINE DIESEL.

COQUETTE, POST HER LOEW KNIGHT-ERA

I know of only two boats that have these very rare versions of the Knight sleeve valve engine. One is the 1928 Colin Wild-built LINDA, which was bought by Roy Swales just after WWII with her original Loew-Knight 6-cylinder petrol engine. I saw it running, and it was incredibly smooth, quiet, and looked very tiny in LINDA’s huge engine room. It was painted silver and had the name “Loew-Knight” in a scroll, cast into the inspection plates on the crankcase. 

Roy W. replaced it in 1947 with a 6/71 GM Detroit 165 HP diesel engine. 

The other boat was the delightful Logan-designed and built COQUETTE, with her sedan top, which was added many years later by Arnold Couldry. He kept her delightful lines perfectly with this addition. She had a 4-cylinder version of the Loew-Knight sleeve valve engine, also painted silver.  I tend to think this may have been her second engine because of her age, having been built in the early 1990s.

MARNINE WITH HER 2 X 6 CYL 163HP FODEN MARINE DIESELS IN MARCH 1963

WHITE CLOUD LAUNCHING DAY WITH HER 4 CYL., HOME MARINISED FODEN DIESEL

There are only three pleasure launches that I know of that have these engines, and there are two with 6-cylinder versions. The LADY MARGARET (built by DICK LANG) replaced her original two Fairbanks Morse Diesels; the MARNINE, which had two of them from when she was built, had the same specifications and was installed at the same time as the LADY MARGARET. The third boat was the WHITE CLOUD, which had a 4-cylinder home-marinized version, fitted by or for, the managing director of Fodenway Motors, Penrose. They were the New Zealand agents for Foden engines at that time and had her built and baselined a generator set to convert the 4-cylinder Foden for marine use in his new boat. This installation took place at their Gt. South Rd premises after being built at 1A Summer St, Ponsonby, by McGeady (Supreme Craft).

In addition to these boats, all RNZN-owned HDMLs and the first of the Police Launches named DEODAR, (DEODAR I), had two of them installed. All were originally 6-cylinder versions; however, but with the HDMLs., some engines were later replaced with 12-cylinder versions in some boats, which were, in effect, two 6-cylinder engines side by side in one crankcase. These had one drive shaft and two crankshafts connected by a system of gearing. At least one twin x 6-cylinder installation is believed to still be in a boat & still surviving today. It is in the massively refurbished, now privately owned KUPARU, primarily located in Whangarei.

Foden engine manufacturing and parts supply were sold to Rolls Royce in the late 1970s, and production ceased when they took over the Foden manufacturing rights.

RAIRA – A Peek Down Below – SOLD

RAIRA – A Peek Down Below – SOLD

Todays classic wooden launch is the 1915 38’ McLeod Brothers Devonport built launch – RAIRA. RAIRA was built to a Collings & Bell design and like most woodys has had a few enhancements (good & bad) over the last 110 years. As she floats today RAIRA is a very handsome craft, but she has a big secret – her interior. Step below deck and you’ll be wowed by her fit out, as seen in the above gallery of photos.

Forward motion is via a Ford Lees 6cyl. 120hp diesel engine that was rebuilt in 2011. At the same time work included replacement of ribs, keel bolts, bulkheads, decks and full refastening and caulking.
Her systems and electrics are as expected for a vessel capable of extended coastal cruising + she sports a diesel cabin heater, so there’s the opportunity for RAIRA to be very comfortable live aboard.

If you haven’t clicked yet – yes RAIRA is for sale and at an asking price of $30k she is very good value for money and her next owner will get a very affordable entry to the classic wooden boating movement.  The asking price is a sad reflection of the boating (wood/glass) market at present. Believe me it will never be cheaper to by your dream boat.

Interested buyers initially to contact owner – Thomas via email at  gosi120@hotmail.com

These are, as one would expect, a brand of engine that is quite rare, resulting from the cost of the engines to buy and the cost, equally, of parts for all maintenance. Also, while Rolls Royce has the name synonymous with perfection in all respects, it is my view that, in fact, Gardner engines are far superior in every respect, including noise, smooth running, longevity, maintenance necessity, and costs thereof. However, there are a few that are in the boats of today and yesterday. I personally know only three.

There is the KUDU, a large launch that, at one time, in mid to late 1966 to perhaps somewhere around the 1980s, belonged to the late Harry Julian. She is 63 feet long and powered by 2 x 137hp Rolls Royce 6-cylinder diesel engines. She was designed and built under Lloyd’s supervision in the UK in 1964 and sailed out to NZ as the end of a 20,000 km journey. However, the last time I saw her was on a visit to the Gold Coast in Australia, anchored in the middle of the center of Sanctuary Cove Marina.

Another of the RR-powered boats is the OHORERE, built by Percy Vos in Auckland for the government of the day to be a high-speed fisheries patrol craft, and designed by Thornycroft in the UK. However, she never reached anything close to her anticipated speed projections as required in the order from the government to the designers and builders. Large sums of money were spent collectively by the designers, Rolls Royce, and the builders to give her better performance, but they failed miserably, and she was ultimately sold to private ownership, where she has been used for many years now for fishing charters in Tauranga. As of now, Rolls Royce’s were replaced about two years ago with 2 x 770hp MTU marinized Mercedes Benz diesels and is capable of around 30 knots.

There is one more pleasure craft, an ex-Whangarei pilot boat and that is the MANAIA, which has had from new, 2 x Rolls Royce 8-cylinder inline 16-litre diesels.

I am aware of one of these in New Zealand, which was in the OTAZEL, owned by Arch Tucket, in the late 1940s to the 1960s. He was the head of the patrol craft section for T.E.A.L. at that time in Mechanics Bay, and he fitted it to her on the hardstand at Okahu Bay in the winter of 1950.

The only boat I’m aware of that had one of these was Sir Len Southard’s champion racing boat, REDHEAD, which won, at one time or another, most of the cups and awards, as well as a huge number of races in her time. She was a real champion, designed, built, and raced by the late Sir Len Southward of Wellington, a brilliant engineer and philanthropist. John Bullivant tells has advised there was a second high-speed hydroplane racing boat built with a marine-converted V12 GM Allison petrol engine in the same era.

LADY STERLING

The 52-foot, 105-year-old Bailey & Lowe-built ocean-going yacht, built in 1920 is named LADY STERLING. This yacht had one of these engines originally, and there were other boats that had them in the earlyish 1900s. 

LADY STERLING has, in recent times, been in the Queenstown area, but she has traveled many thousands of sea miles, with numerous crossings of the Pacific Ocean in her long life. 

Around the end of WWII, she belonged to Stan Waters. She passed shortly after to Lloyd McIvor, a dentist, who sailed her several times a year to Fiji and other Pacific islands to attend to the islanders’ dental issues.

TASMAN WITH A STERLING 6CYL DUAL IGNITION 115HP WWII U.S. NAVY PETROL ENGINE.

A reference in part 1 of this series was made in the comments section by Denis O’Callahan, related to the TASMAN having had a WWII ex-US Navy 6-cylinder flathead Sterling petrol engine at some stage, pre-1975. I have researched this engine and found the following information and images related to it, which I am confident may well be the engine he was referring to.

A quote from Tom Ball in 2016: “I have acquired this engine recently. It is a six-cylinder marine engine with dual ignition. It is 115 HP with a water-cooled exhaust. These Sterling petrol engines were made in Buffalo, New York. The engine supposedly was in a naval ship of some sort and may have come from the naval yard there.” – unquote

As I also said in part 1, I was aboard TASMAN, Christmas 1947 with my father one day & owner, Jack Brooke, lifted the bridgedeck floor & showed us her huge bottle green 225 hp overhead valve Kermath Sea Wolf  petrol engine, identical to that in the above image.

I could see by its size & overall concept, it was a fairly old engine, & perhaps the original, & in the circumstances, I have taken what to me, is a logical view, that this engine was probably replaced around 1960ish by the Sterling, due to old age , &/or perhaps maintenance issues, as well as huge quantities of petrol it must have consumed. Also, it was usually pushed at high speed most of the time by Jack B who was a speed fiend, when it came to his boat, which must have given the engine a hard life.  

19-04-2025 INPUT ex RUSSELL WARD – “I have a little input into Tasman when she had the Stirling engine in the early -mid ’60s. We used to describe it as a “Sterling Dolphin” in the day. My mother had a business connection with her then owner Dr Jim Sprott and I had the chance to see over Tasman and especially to view her engine. It was a four cylinder T head type engine -two blocks of two and quite tall. Certainly painted green with lots of brass -It ran delightfully smoothly and the owner averred that it was not too thirsty if throttled back. His suggestion was that the Americans installed the engine during the war to get more speed out of her. It certainly was a very old vintage- looking engine and had none of the looks of the more modern engines.

Dr Sprott later decided to replace it because of the petrol it used and maintenance. It was offered to MoTat who refused and my father wouldn’t allow me to have it and the word was that it was scrapped. RIP.”

26-04-2025 INPUT ex DENIS O’CALLAHAN – below further information regarding the Sterling engine in the launch – TASMAN

In 1970, TASMAN was purchased from Dr.Jim Sprott by my friend Allan Tyler and his dad Eric.

She had a Sterling 6 cylinder petrol engine with dual ignition and we were told that the original engine may have been a Kermath.

We had many adventures with this engine. One time at Tryphena she would not start and we found the Bendix Spring was broken. To our relief we found several spare springs in the locker so it must have happened before.

The Sterling was replaced in 1976 with a Lees Marine 6 cylinder Ford diesel. New stainless steel fuel tanks amidships replaced the old copper tanks under the aft deck which became the water tanks. The old Sterling engine went to scrap but we retained the name plates which were passed on to the new owner of TASMAN, Stephen Cashmore.

Photographs of these plates are below and the following is my interpretation:

In 2019 I visited Buffalo New York on a cruise through the Erie Canal and Great Lakes and looked for the old Sterling works.

I found that Sterling had been taken over by Phillips Petroleum in the late 1950s and the assets moved to Kansas.

The Sterling Company dates back to about 1903 and many speed records were held by boats with Sterling engines.

STERLING TEE HEAD 4 CYL PETROL MARINE ENGINE SIMILAR TO THAT AS DESCRIBED BY RUSSELL WARD ABOVE THAT HE COMMENTS WAS INSTALLED IN TASMAN IN THE 1960’S AFTER HER ORIGINAL KERMATH SEAWOLF

THE LAUNCH STERLING

I have researched extensively but have been unable to source an image of the 3-cylinder, 27 HP Sterling engine, as referred to below by Harold Kidd and in the launch STERLING as pictured above.  

Input from Harold Kidd: This STERLING was built by Ernie Lane in Picton in 1925 for L.J. Steele as a passenger vessel to carry 60 passengers and had a 1924-built, 3-cylinder, 27 HP (rated) Sterling marine engine with a bore of 4.5″ and a stroke of 5.5″. Dimensions are 34′ x 9′ x 3’9″.

HALL SCOTT DEFENDER V12 PETROL 630HP MARINE ENGINES

NGAROMA WITH HER 1 HALL SCOTT DEFENDER V12 PETROL ENGINE, & 1 GLENIFFER 8 CYL INLINE DIESEL ENGINE, WHEN OWNED BY JIM LAWLER

These Hall Scott Defender petrol engines were used in all Fairmiles during WWII wartime service. When sold into private ownership after the war, all were immediately replaced by diesel engines of various types, brands, and sizes, except for one privately owned Fairmile called the NGAROMA, owned at that time by Jim Lawler. This vessel retained one Hall Scott engine for around two years before replacing it with a second, opposite-handed, 8-cylinder inline Gleniffer Diesel to match the existing Gleniffer 8-cylinder engine he fitted when he purchased the NGAROMA, creating a matched handed pair.

There were also two RNZAF MIAMI CLASS American patrol craft bought by the RNZAF around 1948. One, W275, was sent to Lauthala Bay, Fiji, by the RNZAF, while the other, W276, remained here. W276 had two Hall Scott Defenders mounted in the stern and vee driven.

JUNKERS GERMAN DIESEL AIRCRAFT ENGINE TO BE HOME CONVERTED FOR MARINE USE 

JUNKERS DOUBLE ACTING DUAL PISTON 6 CYL estimated at c.1000HP GERMAN AIRCRAFT ENGINE.

This boat (W276) as featured above, was sold in the 1960s to a Mr. Canavan, a retired senior Air Force officer. He employed two marine engineers to convert two German two-stroke Junkers aircraft diesel engines (probably the same or like those in the image above), which, as far as I can interpret, seem to have been around 1,000 hp each. He acquired and converted them for marine use, replacing the two Hall Scotts with these engines. 

This was a long and very expensive task for Mr. Canavan. During this process, she was moored adjacent to the up-harbour end of the Naval Base and was still painted air force grey. During the installation she acquired four very large exhaust pipe holes near the deck line at the stern.

These engines, like the engine in the hydrofoil MANU-WAI, required hot engine oil to be pumped through them for 20 minutes before cold starts. The two engineers, as mentioned above, eventually finished the project and went off to find Mr. Canavan so he could be present for their first start. While they were away looking for him, he turned up, went out to the boat, saw that they were ready to go, and pushed the buttons. They started but immediately seized up as they had not had the hot oil process completed first.

When the two engineers came back, they were naturally furious that after all their hard work, it had all come to this. So, as one would expect, they just picked up their tools and walked off the job. Eventually, Canavan got two more engineers to rebuild the engines, and while they were in the process of this, one day, when they were brazing with bottled gas, the stern end of the boat caught fire, and the aft 20 feet or thereabouts was destroyed. 

The insurance company sold her “as is, where is,” and someone bought her, chopped off the burnt-out back end, and fitted her, in her now shortened form, with two 6/71 GM Detroit diesels, added new pleasure craft-type coamings, and called her the LADY SOMETHING? or SOMETHING LADY?. This work was all done on the hardstand at Half Moon Bay Marina.

With her back end chopped off and her new coamings fitted, she looked very short and fat.

There were only two boats fitted with the 6-cylinder version of these engines, which had around 100+ hp. 

They were Ted Cooper’s built and owned AWARUA, which for the first couple of years had a Redwing petrol engine. He later replaced this with a Waukesha Hesselman 6-cylinder diesel, which she had for the remainder of his stewardship. A later owner, replaced it with a Ford diesel.

The other boat was the GALA LASS, which had an identical sister ship, the LADY RAE. 

GALA LASS had a Waukesha Hesselman diesel from new for the entire time of ownership by the original owner, Tony Hurt.  The LADY RAE had both one and two engines at different times, both with petrol or diesel, as was appropriate during her early years. I have not been able to locate an image of GALA LASS. I have substituted an image of LADY RAE in place of GALA LASS. 

STELLA – CLASSIC WOODEN BOAT SOS

STELLA – CLASSIC WOODEN BOAT SOS

Last week Andrew Motte-Harrison commented on one of the stories that he had a old kauri launch ’currently deteriorating behind his farm hay shed’.

Andrew believes she was originally named STELLA and alsp possibly named TOILER at another time. Possibly built c.1910>15 by Lane Bros in Christchurch (thats a new one, was there such a place?). Andrew described STELLA as a line fishing boat.

Andrew also commented that when they had her up at the Nelson Marina, talking to an elderly boat builder up there years ago, he passed on what he understood to be some of her history.  He thought she had been working out of Bluff, Hokitika and perhaps Oban in years past (back then)

As the photos show the boat is in need of some serious TLC, starting with a few hours with a water blaster- inside and out. And maybe a session with a tungsten tipped chainsaw and then a new cabin. Her hull deserves saving.

The last photo was taken  over 20 years ago, before being hauled out.

So southern woodys anyone looking for a project, STELLA is located 20 minutes south of Murchison, approx. 2 hours out of Nelson.

INPUT ex DICK HALL – Built by Ernie lane in Picton for the Boese family with a low cabin and rails instead of bulwarks. Later purchased by well known fishing identity Jimmy Aldridge and converted by Jack Morgan with new wheelhouse, bulwarks and new air-cooled Lister. Jim crayfished mostly outside Tory Channel. Next owner Alex McKenzie from Blenheim who re-named her Toiler but after a few years sold her for a bigger vessel. Fished out of Picton all her life before going to Nelson for pleasure conversion. Her original name was Elaine then Toiler. Never Stella while in Picton

AN INSIGHT INTO NZ’S UNIQUE MARINE ENGINES – Part Two

Todays WW story follows on from last weeks story – link below to Part One
Part Two is a little different in that while the story has been pulled together by Ken Ricketts, todays story has benefitted from a lot of editing and polishing from Patricia & Ken Ricketts daughter Corinne Pettersen. As always we have endeavoured to be as factual as possible but there will always by matters others will either know more about or be able to correct errors – so woodys do not hold back in commenting.

WILLYS JEEP WWII 4 CYL UNMARINISED FLATHEAD PETROL ENGINE

WILLYS JEEP 4 CYL PETROL ENGINE PREMARINISED

FAYE WITH HER MARINISED 4CYL WILLYS JEEP PETROL ENGINE c1951

It’s interesting to note how World War II surplus engines found new life in various applications beyond military use, particularly in an unknown number small craft and trailer craft in New Zealand. The experiences of individuals like Fred Steele and Des Donovan exemplify this trend, as they repurposed one of these engines to power their own launch – FAYE,, showcasing the innovative spirit of post-war boat builders. Their simultaneous construction highlights a fascinating moment in maritime history, where practicality and personalisation combined in the crafting of vessels that were shaped by both necessity and craftsmanship.

Fred S. successfully installed a Willys Jeep home-converted WWII 4-cylinder flathead engine, which provided reliable performance for several years before being replaced by a 6-cylinder diesel engine. This setup allowed her to achieve a cruising speed of approximately 7.5 knots, and during this time, my family enjoyed many weekend cruises with them, creating lasting memories on the water.

FAYE WITH HER c100HP HERCULES 6 CYL HOME MARINISED DIESEL ENGINE

RAKANOA WITH HER 275HP HERCULES DIESEL IN NORTH HARBOUR PONUI ISLAND 1948.

Hercules was indeed a significant manufacturer of marine engines, supplying foundational engine units to various companies like Kermath, Chrysler, and others for customization to their specific requirements. While Hercules engines themselves were produced in smaller quantities and considered comparatively small-scale, the widespread use of their core engine designs across multiple brands highlighted the company’s crucial role in the marine engine industry during its era.

FAYE is an interesting vessel with its history of engine replacement, especially from a Willys Jeep petrol engine to a home-marinised C100P 6-cylinder Hercules diesel. This transition not only reflects an upgrade in power and efficiency but also shows the adaptability of boats to modern diesel technology. 

RAKANOA, a stunning 56-foot vessel built between 1946-7, originally featured a 165HP GM Detroit engine but was upgraded to a 250HP Hercules diesel after a year in the water, likely due to the engineering expertise of her first owner, Stan Parker & shortcomings he found with the GM Detroit engine. Despite the initial enhancements, there was a persistent starting issues with the Hercules, particularly when hot, leading son Ross to replace it with a Gardner 6L3 diesel in 1981, which remains with the boat to this day.

The decision to replace the original engine with a Hercules engine stemmed from the excessive noise produced by the Rootes blower and the GM Detroit engine, which was particularly problematic due to the loud high-pitched geartrain noise and the inherent loud exhaust of the 2-stroke GM engines, known for their sensitivity to exhaust back pressure unless equipped with specialized mufflers.

NGAROMA WITH HER 2 X 8 CYL IN LINE GLENIFFER DIESELS, TAKEN, ACTING AS MOTHER SHIP, IN A FIJI YACHT RACE IN THE 1950s

There is a rare type of engine that has a limited presence in New Zealand, with only a known petrol and diesel example known to me.. The mention of potentially more examples from the 1920s and 1930s suggests these engines might have been utilized in vintage boats that are either no longer in operation or have been lost to time. Such rarity adds to their historical significance and appeal among collectors and enthusiasts.

The GLENIFFER, a 40 ft bridge decker constructed by Bailey in 1929, has most recently served as a liveaboard in New Zealand’s South Island, showcasing its enduring appeal and adaptability over the decades.

 In the early to mid-1930s Ralph Ricketts was tasked with maintaining a boat for Trevor Davis. The boat had a critical issue where the sea water intake could airlock in rough seas, necessitating someone to lie on the floor under the bridge deck to turn a grease cup on the water pump to resume water flow, a challenging job made more difficult by poor conditions.

The ex-WWII Fairmile boat NGAROMA, formerly owned by Jim Lawler, underwent significant modifications after he acquired her from the Navy. Initially equipped with two Hall Scott Defender 630hp petrol engines, Lawler immediately replaced one with a Gleniffer 160hp diesel engine and later replaced the remaining Hall Scott engine with another Gleniffer diesel engine, both designed to be a matched pair with opposite hand configurations for optimal performance.

 BUICK 8 CYLINDER INLINE PETROL ENGINES

AOMA WITH HER HOME MARINISED BUICK 8 CYL. INLINE PETROL ENGINE AS ORIGINAL WHEN BUILT BY ALAN WILLIAMS

AOMA ON HER MOORINGS AT GT BARRIER ISLAND RECENTLY

AOMA, a 36-foot vessel built by Alan Williams around 1950 in Milford Creek, Auckland, was either commissioned by or later acquired by Len Pepper, a prominent builder from Takapuna. Initially equipped with a home-marinised 8-cylinder in line Buick petrol engine, AOMA reflects the craftsmanship and maritime heritage of its time, showcasing the evolution of boatbuilding in New Zealand.

Observations about the engine’s appearance and the “Buick Detroit Marine” label suggest it could indeed be a locally modified version rather than an official marine model from General Motors. The lack of verifiable references to a marine variant strengthens your hypothesis about it being a custom marinization. Such practices were not uncommon, especially in regions where specific adaptations for marine use were necessary, and the label may have been a marketing choice to lend credibility or appeal to customers.

AOMA’s design is a classic example of form versus function, where the elegant lines that defined her aesthetic have been altered for improved practicality. While enhancing the headroom may provide comfort for passengers, the modification to her coamings appears to have detracted from her original beauty. Such changes often spark debate among enthusiasts and owners about the balance between maintaining a vessel’s traditional design and adapting it for modern usability.

MASON MARINE 42 FOOT MASON CLIPPERS & CHRYSLER V8 MARINE DIESEL ENGINES WITH STERN DRIVES.

Tony Mason crafted a series of impressive boats like the ALIBI, characterised by their striking design and powerful performance, especially with the dual 6-cylinder diesel engines that presumably enhance their speed and efficiency on the water. These boats show cased both his craftsmanship and a commitment to quality, making them stand out in any marine setting. I am trying to find another of these boats, that one day was tied up to Mansion House Bay Wharf, in the early 1970s, when the boat was almost new.   She was amazing as ALIBI still is today, but the thing that intrigued me most was her 2 Chrysler V8 diesels, painted red, as with Iveco or Redwing, with her stern drives painted cream. The engines looked the same as Chrysler V8 petrol engines, except they had injectors not spark plugs, they were the only two of these engines I have ever seen.
