What Does Electrochemical Deterioration In a Wooden Boat Look Like
 
Todays story is in two parts – firstly the photos above were sent in by a concerned woody that viewed this boat, with purchase in mind. I share to highlight what electrochemical deterioration in a wooden boat looks like. This decay is the result of ignorance.  The builders of this launch would have used the best kauri and proper Aluminium bronze for the stern gear. Marin bronze does not require an anode but you can see where one has been mounted (rusty mounting) You can see the copper strap used to connect all the metals to the anode. A perfect example of what you should not do on a wooden boat. After about two years you will see discolouration of the wood around the so called protected metal , in ten years the wood will be soft and in twenty years uneconomical to repair. So woodys – read below an abridged version of Chris’s WW article. I do encourage you to take the time to review the long version as it appears on WW – link below    https://waitematawoodys.com/2016/04/28/electro-chemical-damage-in-wooden-boats/
 
 
Firstly I should point out that Chris repeatedly points out he is not a consultant and does not have a degree in Chemistry. But his views are the result almost 60 years of working in boatyards. 
 
“If you connect a positive and negative metal in salt water you will make a battery and create an anode and a cathode. The negative (protected) metal is the Cathode.  The positive anode gives off Chlorine gas and the Cathode Hydrogen gas. 
That is why battery compartments have to be ventilated. Back to the Cathode. The Hydrogen from the protected Cathode mixes with the salt water and the by product is Sodium Hydroxide or Caustic Soda. Caustic Soda is used as paint remover and to pulp wood in the paper industry. Want that on your boat?
While a lot of boats may have no bonding, they do have anodes on the shaft. The shaft is in affect the bonding wire between the (+) Anode and (via the white metal bearing) the (-)bronze stuffing gland.  Zinc is at the bottom of the galvanic scale and bronze and copper could not be more dissimilar.  So there is your battery, the salt water is the electrolyte.
The Sodium Hydroxide is washed off the outside of the hull so you don’t see it but the chemical is trapped under huge pressure round the stuffing gland and slowly forces it’s way out. That is the white powder you see. Unfortunately, even if you remove the Anode the chemical will remain in the shaft log and soften the wood. 
A proper fix is to remove the gland and soak the wood in vinegar.
Cathodic protection is necessary on a steel hull but should never be used on a wooden boat. Marine surveyors round the world are now awake to this after seeing some ruined wooden boats.  Wooden Boat Magazine, Professional Boatbuilder Magazine and Classic Boat Magazine have all written on this subject. Some of the articles are thirty years ago, but few people in New Zealand seem to read this technical stuff and they fork out $ for anodes every year i.e. Loving their boat to death”.

VAGRANT N17
 
During the week I was contacted by Stuart Windross in regard to the mullet boat Vagrant, built in the early 1920’s by his grandfather Jack Greenhalgh. I’ll let Stuart tell that story below. 
Then out of the blue while I’m on fb & up pops on the Whangateau Traditional Boat yard page the pictorial of Vagrant being salvaged after sinking at her moorings in Okahu Bay 3 weeks ago. Vagrant was raised and barged ashore on Tuesday, then brought up road by Boat Haulage arriving at the WTB yard on Wednesday. 
I understand that Vagrant  was saved from the crusher by Dino Herbisone, who will carry out her repairs at the WTB yard. 
It would be amiss of me to not mention the wonderful contribution to our wooden boating community the Pam Cundy & George Emtage offer up at the WTB yard. I do not think the word NO is in their vocabulary, they so generously offer up the yard to help stop the demise of heritage craft and then pair the boats up to capable tradesman or people that can repair them if need be or indeed use and enjoy them. The yard can be contacted via email at 
“Further to the discussion regarding the builder of the mullet boat Vagrant I have followed up my post confirming it was built by my grandfather Jack Greenhalgh with a delve in the family photos. 
Attached please find photos of Vagrant  N17 under construction and one of her sailing close to the camera in light winds bow on.  These are verified as they have her name inscribed on the back.
The other pics below, are of what I believe to be an 18 footer named Vim that my Pop John (Jack Greenhalgh) also built prior to Vagrant.  From one of the photos it is pretty clear that her number is V34.  I wonder if you have any info about her fate as she seems absent from online records and the literature.
John (Jack) Greenhalgh was born 20 June 1901 at Riverhead and died 13 July 1984 at Waitakere Hospital.  He was the middle child of 11 born to Edward Walls Greenhalgh and Helen Ramsay (nee Paterson).  His grandfather John William Greenhalgh, originally a coalminer from Wigan UK arrived in NZ in 1886 to oversee the establishment of paper mills at both Mataura and Riverhead.  His father Edward Walls Greenhalgh also worked in the paper mills both at Riverhead and Mataura later living in Richmond Road Auckland.   At the time of building Vagrant he would have been 24 and obviously younger when he built Vim.  He kept the scale half models of their hull shapes (shaped from Kauri) throughout his life.  My Auntie may know of their whereabouts. I believe that both of these boats were built in the back yard of his parents home at Richmond Road.  As you will see the set up was fairly basic!   
Albert Greenhalgh (Alby Jack’s brother) was born in 1906 and I understand was a sailing partner.  The two brothers were very close, marrying sisters (Doreen) Vera and (Florence) Rita Lee.   Alby and Rita’s son Keith is still active in the Reactor sailing fraternity and daughter Beverley’s husband Jaape Pos was a boat builder (at Sea Nymph I think).  Another cousin was Roy Parris (the well known launch builder).
Jack and Vera married in November 1926 and soon purchased a new home in Kingsley St.  This transaction probably necessitated the sale of Vagrant. A later craft (a dinghy I believe the kids used for fishing trips and floundering in Coxs Bay) was built in the front room of the marital home much to the displeasure of his new wife.
A mischievous and witty character he was always ready to enthrall us with a prank or yarn.  I recall his stories of searching shoreline pohutakawa for suitable bends for stems or knees and cutting the corners off square balks of timber to fashion his masts.  He was a very patient worker in wood or metal.
I have included a photo of Jack and Vera Greenhalgh(with my Mum) c1938
I am not 100% sure if all the fleet shots are of Vim but the colour scheme suggests so (unless Vagrant’s cabin sides were painted darker at some stage).
Apologies for the picture quality as the originals are very small and showing their age”.

The Order Book Is Open For Waitematawoodys T-Shirts

Yesterday’s story on the re-launching of Pacific & My Girl, caused a bit of a stir – nothing to do with the boats, it was all about the photos of people wearing waitematawoodys t-shirts, my email inbox was overflowing with – where’s mine?, where can I buy them? etc.

So folks, it’s been 2 years since I offered up the chance to grab your own WW t-shirt, last year I was just too busy with the boring things in life e.g. work & also getting my boat ready of the Christmas/ NY cruising. This year I’m ahead of the game, for once 🙂 Also the numbers of people reading WW has increased by over 500%, so there are a lot naked woodys out there 🙂

  1. Some background on the T’s – I only source top quality garments & use high-end screen printing for really tight detail & a durable finish. I’m passionate about WW & will only put the logo on something that is 100% quality.
  2. In terms of colour – previously I printed a very dark blue (navy) T, with white logo. So it’s that again. Over the last 2 years I have printed other colours for friends & give-ways, no promises but I might do another colour – e.g. black, let me know if you had a 2nd pick & I’ll see (no promises) how things go. The logistics of the ordering > printing > dispatch is a little frightening, my lips are sealed on numbers, but the house looked like a NZPost mail center for a few weeks.
  3. Price – same as 2 years ago $34.95 (gst inclusive) + $5 p&p (one off freight charge, no matter the number you order). If that’s too much to pay for a quality T-shirt, well I guess you won’t be buying one, but I’m not prepared to compromise on standards.
  4. Sizes? Refer chart below. If there was interest I could do a smaller female size.
  5. Ordering – B4 Xmas I’m doing a limited print run, so if you want a shirt/s – I need your order by Friday 30th November, sooner would be even better. I’ll advise payment details when I confirm your order.
  6. What’s next – email me at waitematawoodys@gmail.com & advise:

 

# Your name 

# Postal address

# Phone

# Quantity & size/s 

Ps – Sent in a sealed courier bag, so if you are ordering for a Xmas present, no-one will know the contents.

Pps – Yes, I can send overseas – freight costs tba

Ppps – My models where flown in from Milan for the shot photo, at great expense – they won’t have to worry about ordering a new shirt 😉

MY GIRL and PACIFIC Relaunched – 60+ Wooden Boat Photos

Big day on Saturday in the woody world, we had the launching of Pacific & My Girl. Pacific is a 1917 Joe Slattery designed & built launch, owned by Nathan Herbert, & has been out all winter at Milford Crusing Club’s yard getting a major over-haul – hats off to Nathan, Pacific is a stunner, the perfect choice & mix of colours & varnish. It has been a long winter but from the smiles on everyones face, dock-side, it was all worth it. This WW link will give you a peek at what she used to look like.   https://waitematawoodys.com/2014/02/07/5898/
Well done Nathan & Steven + a big cast of helpers thru-out the project.
Second splash was Jason Prew’s – 1925, Dick Lang built ‘My Girl’, also re-launched at MCC. Jason’s re-build of My Girl has been a very long 4 years, mostly out of sight in a cold (& sometimes wet) commercial storage yard. My Girl arrived at MCC approx. 6 weeks ago for the final touches. Some of NZ’s most respected woodys were shaking their heads when Jason bought My Girl, she was so close to being a BeeHive (box of matches) restoration, but Jason has a track record of bring woodys back from the dead & that he did with My Girl. This link will show you what he started with    https://waitematawoodys.com/2014/12/12/my-girl/
To see more of the project – check out his weblog.  https://www.my-girl.co.nz/mygirl/Welcome.html
Post launching, I managed to score an invite to go for a blast on My Girl, she is fast (my lips are sealed) but I expected that, what really impressed my was the ride – very smooth. The question of the day was – are classic woodys allowed trim tabs 🙂 I seem to recall James Mobberley had some ‘additions’ on Falcon…………..
Remember click on photos to enlarge 😉

ELLA B – 4 Sale
 
I have been contacted by Taupo woody, Shawn Vennell regarding the very smart woody – Ella B.
 
Ella B is a ‘Monte Carlo’ design, barrel-back, classic inboard mahogany run-about. She was built in NZ by Bill Brassington, & measures 24’6” with a 7’6” beam.
The zoom zoom is via a brand new 5.7 litre 350 BFI marine V8 Kodiak engine complete with a Borg Warner 71c model 1.1 velvet drive transmission. The build quality & attention to detail is amazing + all components in the build were brand new, with the trailer being custom made by Bill.
 
Unfortunately due to health issues, Ella B is reluctantly for sale. This is a turn-key boat, fill the tank & you are off. I suspect the seller is very realistic in terms of a price, interested parties can contact Bill’s son Glen, via email  ellaco@xtra.co.nz to discuss Ella B in more detail.
 
Ella B has appeared on WW b4 – more details here.
 

 

Folly III

FOLLY III

Today’s woody story features a 5’10” video on Folly III, a 33’ cruiser designed by W. Holmes & built by his sons, Reginald & William, c.1920 in Sydney, Australia. Her beam is 9′ & she draws 3′.
I understand Holmes senior was a kiwi builder that moved to Sydney to build bridges & later turned his talents to wooden boats, of all shapes & sizes.
I’m sure HDK will be able to enlighten us on the man.
The Folly III design follows the look of the popular American Lake Union Dream Boats.
The video is beautifully shot in Moreton Bay, Queensland & has a ‘colourful’ commentary from the Folly III owner, Stephen Lake 🙂 Enjoy
Thanks to woody John Sloane for the heads up on the video.

Aurora – Sailing Sunday

Waiheke Island, March 2018

 

AURORA – Sailing Sunday

The other day I received a note from Bill Brown, the owner of the lovely yacht – Susan Jane, that featured on WW when she was being restored at Colin Brown’s Omaha yard.
Bill is a kiwi but works overseas & was delighted to see that his uncle’s old yacht – Aurora appear on WW (link below) recently. Aurora is a 22′ Harrison Butler design, built & owned by his uncle, Neil Brown c.1940’s.
Bill’s father, James Brown, a salty old dog who spent most of his time going up and down the Whangarei Harbour, in various craft, including Woodys; Sarina, (currently for sale, and whom mum and dad had their honeymoon on) Temptress and Yvonne. James passed away last April, just a few days shy of 90, having sailed his entire life, and selling his last boat at the grand old age of 80.
The timing of the WW story on Aurora was very opportune as Bill had recently been canvassing the extended family for  details – with Bill’s permission I have published below the email he sent out – its an great read. Enjoy.
“I saw Aurora for sale on Trademe yesterday and I thought you might be interested in seeing these pictures of her. As far as I know Uncle Neil built her himself in Dunedin to a Norwegian design. Dad used to tell me she was built like a brick outhouse and you can see that even though she is clearly neglected, she is still a tight wee ship! The photos and advertisement make her seem much bigger than she is. I think she is only 21 feet long, making her essentially the size of a trailer sailor!
Most of you know that Uncle Neil sailed her in the famous Wellington to Lyttelton yacht race that was at the time one of New Zealand’s worst sailing tragedies. That was perhaps the first, but not the last time, that old Gran thought Uncle Neil had been lost at sea!
If I remember correctly, dad used to say that Uncle Neil ran before the storm with bare poles and with a spare anchor warp streaming out the stern. As it states in the article he eventually ended up in clear skies up off the coast of the Hawkes Bay.
The other great story I remember about Aurora that was more directly connected to dad, was that Uncle Neil asked if dad wanted to go on a summer cruise from Dunedin to Auckland to coincide with the Queen’s visit in 1953-1954. Dad said yes and that was the plan they told Gran, however when they cleared the Otago Heads Uncle Neil kept heading east! It wasn’t till then that he told dad that they were aiming to be the first pleasure yacht to visit the Chatham Islands post WW2! Uncle Neil figured that if he had told dad the truth he wouldn’t have said yes and Gran would have worried too much. I remember dad had a handwritten log of the voyage, boasting of the huge crayfish they ate when they finally arrived at Waitangi, Chatham Islands. After a few days socialising with the locals they then set a course for Auckland to visit the Queen!
I have seen her only twice in the real flesh. Once she was waiting outside the Kissing Point Boatshed that we kept the launch Yvonne in. We were returning from a weekend down the Whangarei Harbour and the owner had tracked dad down to have a chat with him about her history. I think she was then based in Tauranga. The second time I spied her she was on a swing mooring in the Tamaki River.  I was at University and I had been out windsurfing and noticed her and that there was a guy in the cockpit. I stopped at her stern and explained that my uncle had built her and found out that the guy in the cockpit was readying her for sale, as her owner had been in some trouble picking up the mooring, bouncing off a few boats in the tide and had suffered a heart attack!
Uncle Neil’s second major build was the modified Woollacott – Katherine Anne, Maraval (photo below), which he built in Whangarei, at Smiths boatyard and sailed around the South Pacific and the east coast of Australia, ending up back in Dunedin. I heard that he received a RNZYS Blue Water Cruising Award for this effort, but I can’t seem to find much evidence of that. An interesting aside to this cruise was when I sailed in the Farr 9.2 Interdominion series in Perth Australia, there was a crew from Wellington, who recounted a story of Uncle Neil on Maraval being in Hobart at the same time as the finish of the Sydney- Hobart Yacht Race that they had just competed in a fully powered up ocean racing yacht. Apparently as the story goes, they left Hobart together and Uncle Neil beat them back across the Tasman!
Back in Dunedin, for summer holidays Uncle Neil would head around to Fiordland, down to Stewart Island, even on one occasion venturing to the Campbell and Auckland islands.  Sometimes just for the heck of it he would throw in a circumnavigation of the South Island. On one occasion he lost Maraval, when she was washed out to see by a flood, after sheltering in Port Jackson, Jackson Bay, West Coast, only for Maraval to float out into the Tasman and a few weeks later return on to a piece of sandy West Coast beach up by Greymouth! The only reported damage to her was the broken mast and the front bollard that the farmer had tied his tow rope to as he hauled her up the beach! He re-floated her, had her towed by a fishing boat to Greymouth, built a new mast and went on his way back to Dunedin.”
