ELECTRO-CHEMICAL DAMAGE IN WOODEN BOATS UPDATE
A Special Post By Chris McMullen

Recently I received a note from Chris where he questioned if the story we posted last year on ww about electro-chemical damage to wood  was a little too long & were people reading it. Well I can tell you that the post is the single most visited story on ww, ever, & gets read by people all over the world. Its frequently referred to on the hugely popular WoodenBoat Forum in the USA. The link below takes you to the original story.

Electrochemical Damage To Wood – the marine version of ‘leaky homes’

For the impatient ones out there 🙂 Chris has done a ‘Readers Digest’ version & refers to a vessel that recently featured on ww.
I encourage all of you to read today’s story & if you own a classic wooden boat – read both versions – the problem is the biggest risk to the life of our classic boats.

In Chris’s words:
“I received the above disturbing images of another woody being destroyed by an owner who I believe is unintentionally loving his boat to death.

The use of anodes and bonding on a wooden boat is fatal. The cathode or protected metal makes hydrogen gas and this combined with saltwater makes Sodium Hydroxide (Caustic Soda). This chemical is used to pulp wood in the paper making industry. Not on my boat thank you! I say again, there is no reason to use anodes and bonding on any boat. The only exception, steel hulls require anodes. If copper or bronze are being corroded it is due to a positive DC leak and Zinc anodes will not help. Find the electrical leak is the cure. If there is brass or manganese bronze underwater it will corrode due to the
zinc in the alloy. Anodes will possibly stop the corrosion but at the expense of wood damage. A better plan is to replace the brass with proper marine bronze.

Bronze and copper should last indefinitely in the sea. To prove that statement, I ask you to look at the Roman coins and artifacts salvaged from ships wrecked in the fourteenth century. There was no anodic protection and the metal is well preserved. So what is the difference to the copper and bronze on your boat? There is absolutely no difference so why waste your money buying anodes that will in time destroy
your wooden boat.

Three or four bottles of wine will cost the same as anodes and will make you and your boat happier.”

Note: ww is read all around the world, if there is water & boats, there are people reading ww. So a little about the man for non kiwi’s  – Chris is one of NZ’s most respected boat builders (retired) and at one time was the Lloyds (Honorary) Wood Boat Surveyor in Auckland. Chris’s (the original company) ‘McMullen & Wing’ built and repaired wood, steel and marine aluminium vessels. They built the first welded aluminum vessels in NZ. Chris is the current holder of the Classic Yacht Association of New Zealand ‘Outstanding Achievement Trophy’ for services to classic boating.

Gavin Gault sent in the below photos of a Nova skeg floor that he believes were probably damaged due to engine – anode bonding failure. Pretty graphic !!

 

10-07-2016 Reply from Chris McMullen

“Wow. Thank you Gavin Gault for sharing your very graphic images. Very sad, small consolation but yours will not be the only wooden boat affected by this scourge.
Maybe, at last some of the Flat Earth Society will start to believe what I have been saying. The worst detractors are some in the Marine Industry who have been preaching the Anode, Bonding party line for years.  Now there is no where to run for cover,  they continue to conjure up excuses and it seems, refuse to accept a simple scientific fact.
“If you have a positive and negative electrode in salt water, the negative cathode or protected metal makes hydrogen gas and this combined with salt water makes Sodium hydroxide.”
This chemical is also known as caustic soda and removes paint and destroys wood.  There is no doubt about this fact. You do require a power source and bonded dissimilar metals ( zinc and copper) provide sufficient current to do the damage, but slowly.
If there is a negative DC leak (to the sea)on a bonded boat the process is accelerated. If there is a positive leak any metal becomes an anode and will waste away. It is important to isolate the DC power from contact with the sea. Again bonding is just asking for trouble. Please remove Anodes and Bonding from your wooden boat now!
Chris McMullen”

Jack Brooke Cruise Collection #13 – Kiariki Xmas 1961/62 – Revisited

So far there have been over 2,000 classic wooden boat stories featured on waitematawoodys & the viewing numbers (3,300,000) have grown from a dozen people to over 80,000, I have had some loyalists from day one but the big numbers have happened in the last 2 years – so not everyone will have been exposed to all the stories. Over the Christmas / NY period I have decided to take a peek back in time & feature some of the gems from the early days. Enjoy.

Have a great holiday & remember to take the camera / phone with you & snap a photo of any woodys you see. Email them to waitematawoodys@gmail.com

 

Jack Brooke Cruise Collection #13 – Kiariki Xmas  1961/62

Another  Jack Brooke drawing, published on ww thanks to son Robert making them available to ww followers. Jack produced a hand drawing on each cruise. Todays post is the 13th featured.

The above drawing records the travels of Kiariki during the Xmas 1961/62 cruise to Kawau Island, Kerikeri (Bay of Islands), Great Barrier all points in-between. Sounds like the weather gods did not smile for the trip north. If Robert or Judith are reading they might like to enlighten readers on the ‘birds & wasps’ reference.

Rawhiti – Revisited

Rawhiti – A Once In Your Life Time Opportunity
photos ex Classic Boat, Chris Miller, Alan H & owner

Firstly – a challenge – can anyone dispute that Rawhiti is New Zealand’s finest classic yacht afloat? From all angles she is simply beautiful, a true classic from the drawing board of Arch Logan & built by Logan Bros.
Rawhiti was completely rebuilt by Peter Brookes at Brookes Boatbuilders in 2011. For her owner Greg Lee, it was a pure labour of love, he extensively researched every aspect of the project & worked alongside Peter on a daily basis, the end result being a Logan that is better than launch day in October 1906 & thats pretty bold statement to make about a Logan.

Yachts like Rawhiti only come along once in a life time, to get the chance to buy one is even rarer. That opportunity now exists, to do that – to own this beautiful piece of New Zealand’s maritime heritage, a floating work of art.

So my 2nd challenge today is to all classic boating aficionados – gather your friends or business associates & form a syndicate, sell that bloody ugly Colin McCahn, sell a few shares, sub-divide that section – do what ever you have to do, to put the money together to acquire Rawhiti.

Interested? – read on

Without boring you with details, Rawhiti’s owner is serious about selling her & now via another business transaction has the opportunity to offer Rawhiti for sale to the right owner for a fractional of the restoration cost i.e. in the $400k range.
The time window in which the business transaction is available is short and therefore there is a limit to how long Rawhiti will be marketed in this price range. If you are interested in discussing the sale, please initially, contact the owner Greg Lee on the email address below.
For anyone with an interest in acquiring Rawhiti who is unsure what they might be doing with her in the short term (but wishing to secure the opportunity to acquire her now), her owner has had provisional discussions with Peter Brookes about storing her under cover at his yard at favourable rates.

Owner email contact:       greg-lee@xtra.co.nz

Update 29-09-2019 Below is a  sneak peek at Rawhiti when she was in Australia – the photo appeared in the Sept 1925 edition of the ‘Australian Motor Boating and Yachting Monthly. Sent in by Andrew Christie.

Classic vintage 1936 ketch – Leisure Hour

The above 32’ x 9’ beam ketch is named Leisure Hour & was reportedly built by Jimmy Reid in 1936 in his family yard at Sulphur Beach Road Birkenhead, close to the Auckland Harbour Bridge location.

The Reid family being reputable boat builder of vessels in early 1900 in Mechanics Bay area Auckland, had two sons who produced sail and power vessel for notable New Zealanders of that era.

Leisure Hour has been on the harbour for approx. 81 years and is in need of a tender loving owner to take on as a project vessel to keep Auckland boating history alive.

She has had work completed with a tidy up and new paint. Her engine is a two-cylinder Arona diesel, with mechanical transmission and shaft drive.

The current owner on trademe says he has one too many boats and is motivated to sell – so with an asking price of $19,500 Leisure could a perfect entry into the classic wooden boating world J

Telstar – Sailing Sunday

Unknown

TELSTAR – SAILING SUNDAY

I was recently contacted by Drew Thompson, who is trying to track down details on his grandfathers yacht – Telstar. Telstar was designed and built the grandfather, Ivan Vitali, in 1970 from solid kauri, then glassed over. She was based on an Alan Buchanan bermudan sloop and was 33’ 6” in length.

Ivan registered Telstar with NZ Yachting so he could race and was given the sail number 1263. NZ Yachting told Drew the name was changed to Goldline – Drew tracked that lead but the owner (Murray Smith) said the yacht was never called Goldline, but Kishmul.

The history that Drew is aware of it that she was sold in 1974 when Ivan died to Chris Smith (who owns Moana at Devonport YC) who sailed her around the world before selling her in 1985. Chris believes she ran around in Noumea around 1989, but was recovered and brought back to Westhaven and repaired and that’s where the trail goes cold. Any info, insights that we can give Drew, would be much appreciated

Drew commented that the photos, from the 1970’s are not good. The writing on one picture is from Drew’s 90-year-old uncle, Lolly Vitali – the picture has been on his wall about 40 years 🙂

 

10-10-2023 UPDATE ex Drew Thompson – Telstar is still sailing and still extremely well looked after (photos below) by the now-former Commodore of the Dar es Salaam yacht club, Mark Hart. Mark and I converse regularly – and I’d even planned a trip to sail her on her 50th birthday but Covid stepped in. We caught up via skype on the day – December 16th, 2021 to celebrate. Mark has since mounted a photograph of my grandfather and Telstar designer/builder, Ivan Vitali, below deck. I hope to one get there one day to sail her myself.

A Master Class in Wooden Boat Building

 

A Master Class in Wooden Boat Building

In the past I have published several links to retired Australian boat builder, Ian Smith’s blog (Smithy’s Boatshed) on the building of his 24’ Ranger Class yacht. Today’s link is to the full blog; it is a truly amazing record of how to build a wooden boat. If Ian was to appear on the TV program Mastermind, his specialist topic would be ‘Australian Open Boats’, the man is a living legend. Read / view the story, if you are too busy, bookmark it for later reference.

(thanks to Robin Elliott for pointing me in the direction of Ian’s build / blog)

Waiata H15

WAIATA H15

 A gent by the name of Billy Bott called me last week with a wee problem, with a such a cool name, I couldn’t not help him out

Billy has a 26ft Mullet boat (now in motor launch mode) with a very colourful history. Built by Dick Lang, one of the leading mullet boat builders at the time and launched in 1936. One of the last boats launched before the man power project in 1938. Her first owner, Hec Moylan, won 1st prize in the ‘NZ Art Union’ lottery & commissioned Lang to build the yacht.

Waiata was transported to Japan in 1946 aboard the English aircraft carrier “Gloria” to be used for Rest and Recreation duties by members of the Royal New Zealand Air Force. Waiata was also used for recreational sailing at the RNZAF Sunderland base at Lauthala Bay, Fiji.

In 1984 as the result of a rather big storm, she had a wee altercation with the Westhaven sea wall, at the bottom of Curran Street, Herne Bay (refer press clipping below) & more details on her past.

Today Waiata resides in the Milford Creek. Powered by a 25hp Volvo diesel motor and gearbox. The motor has only done a few hundred hours since being reconditioned. She is very roomy for a 26’ boat, with full head room throughout.

Billy’s problem ? – Waiata needs a new owner, sadly she has not been used lately & someone could acquire her for not a lot of money, in Billy’s words “I’m open to all offers”

For more information call Billy on 0274956561

ERNIE SEAGAR RIP – Saddened to learn of the passing last week of Ernie Seagar, one of the giants of our wooden boating community. 

Harold Kidd Input

Sad indeed to hear about Ernie Seagar’s death. He was already a legend as a boy. He was Head Prefect and Captain of the First XV at Takapuna Grammar in the 5th Form and a very useful cricketer, track and field athlete and yachtsman. In his later years he became a truly admirable hard man from his experiences at sea and in life. A true two-fisted tough-minded Seagar of the great New Zealand engineering family. His great-grandfather worked under Isambard Kingdom Brunel in the construction of the GWR Saltash Bridge and the SS GREAT EASTERN at Milwall.
My sincere condolences to his family.
WAIATA was launched by Dick Lang on October 5 1934, not 1936. My father and mother lived in London Street, just up from St.Mary’s Beach. Dad knew Dick Lang well (as well as Lloyd George).
Boylan raced her infrequently with Ponsonby Cruising Club and Richmond but she was well-known on the waterfront.
This “manpower” comment is way off beam. Between 1934 and 1940 (not 1938….WHY 1938, the war was a year in the future?) when tradesman began to be “manpowered”, many hundreds of yachts and launches were built in Auckland, a large number by Dick Lang.

2017 Centreboard Cup – 50 Photos

P1250800

2017 Centreboard Cup at the Herne Bay Yacht Club, Sloanes Beach

Raindance got a big 24hr workout at the weekend – Friday was the old mates lunch cruise to the Riverhead Pub, then back to Bayswater to drop the crew off & straight down to Waiheke Island for another mates dinner at the Oyster Inn. The nor-west puff put paid to anchoring in Oneroa so a quick call to Stephen Langton secured Kailua’s  mooring at Matiatia for the night.

The Oyster Inn was like a CYA gathering with several woodys there as well enjoying the late avo> evening sun on the deck – great to see Waimiga back in the water after some TLC, looking very sharp.

Up early & back to Auckland to catch the start of the Centreboard Cup. A good breeze ensured some lively racing. I was land based so could only focus on the pre-start > start. But I was perfectly placed to capture Corona’s rather embarrassing oops at the start with a boat-shed – they were over the line at the start (by a country mile) & came back, then it all went pear shaped – check out the slideshow below.

Hopefully someone captured some on-the-water racing photos that we can share on WW?

P1250875

This is the start of the oops, I suspect the skipper under estimated the length of the ramp, that was well submerged by a very high tide

Swiftsure – Restoration Project In-Waiting

Unknown-1

Swiftsure – Restoration Project In-Waiting  

I was recently contacted by Harold Kidd in regard to Swiftsure the 1921 centreboarder that needs major restoration and to the right person –  is free for collection.

Harold supplied some history on the yacht below.

SWIFTSURE was built by George McLean of Birkenhead in 1920 a bit under 16ft and a bit over 14ft (about 4 inches) because of the available lengths of timber.

Her first race appears to have been in November 1921 with the Ponsonby Cruising Club in their “14ft handicap class” i.e. not square-bilge and not Jellicoe Class 14s, owned by G. McLean. She was on scratch which indicates a first race. She raced consistently much of her life. She was registered with the 14ft T Class when the AYMBA introduced its alpha-numeric system in 1922. She was allotted T38.

By the 1923 Anniversary Regatta her oversize had apparently been picked up and she was moved to the 16ft S Class as S62. She was then owned by George’s nephew Ted Fitzgerald. After a protest she had the offending bit sawn off her stern and was reregistered as T6 in 1934. Later he put the 4 inches back on and she raced with the 16 footers as S62.

After he retired her from racing as an open boat post WW2 Ted built on a raised foredeck and a bigger cuddy.He took her on an annual cruise to Great Barrier with his two little girls. Amazing!

Swiftsure is now stored under cover at Beachhaven and stabilized but needs a total restoration. The above photo shows her racing as an S Class. Harold commented that it was hard to photograph her under her current shelter (see below bottom). The 1st group of photos below were taken some years ago before she deteriorated but give a good idea of her final, “cruising” configuration under Ted Fitzgerald’s ownership.

Interested parties can contact Harold via WW  or Grant Firth at gfirth1955@gmail.com
