Epoxy?

[John B]

Most NZ keel boats/ yachts and many launches were cold moulded in one form or another since roughly the 1880's. Initially they were mechanically fastened , say until the late 50's , and then they became glued cold moulded with either resorcinol or epoxy ( as it developed). Many of those boats are with us today, I've run threads on a few of them here over the years and noted here what I've seen. Rainbow and Rawhiti for example , 1895 and 1905 ,are 3 skin Kauri boats and are sailing now with 90 %, arguably significantly more , original hull material. They ain't no Slocum Sprays or Tally Ho's created off a template of an old boat.
Unless lost to tragedy or mishap , the next generation cold moulded glued hulls are with us too( particularly the kauri ones). Mine is 1975, 4 skins resorcinol glued and I regularly sail with contemporary boats from or around the same period( ie 50 years old plus or minus).
I have and do trust it implicitly, it doesn't creak , all the cupboards open in 30 knots, no binding. The sort of boat you can trust to look after you when it gets nasty 500 miles out.

Would this have been possible if Boadicea had been originally built with epoxy?

Absolutely, why not? Obviously the repair/rebuild methods would be different, but if it can be built in the first place, it can be rebuilt ad infinitum too.

The argument that she's a 200 + year old boat...but almost everything's been replaced (multiple times)...."triggers broom".

Ford would say that's enabled because of the construction choice. Bruce would argue that's in part because of the construction choice.

Obviously there's more to it: being in one persons ownership who has the inclination, ability and understanding to repair and maintain something both Boudicea and Woodwind have that in common.

Bruce's planking choice of AYC also has more influence...it's extremely durable. Totem poles of it in Canada are centuries old. Paired with modern durable two pack adhesives and paint coatings that weren't available before, it's clealry demonstrably effective. But we can't build every boat from AYC.

Now read on.

You can repair anything. But sometimes the work is not worth the candle. A major replank of a damaged epoxy cold molded hull, for one thing.

Slocum kept her name Spray, noting, "Now, it is a law in Lloyd's that the Jane repaired all out of the old until she is entirely new is still the Jane."^[5]

Slocum, 1900, p. 7 from Wiki
Actually, Slocum did not comply with that because he built his copy alongside the old hull. He even increased the beam a tad.
Frost did replace the timbers piecemeal, one at a time, as though it were a continual sequence of repairs, with no gaps in between.

This one on Ebay caught my eye this week...

1970's build sail and oar. 15ft x 4'6". So she's 50. Gaff yawl (might be a lug without seeing a hoist).

Construction looks like strip. Some of the frames are sistered and clenech nailed, others no nails so glued construction but no glass?

Rope steerage around the boat a bit Coquina like.

Rear bumpkin over the rudder head gets around that.

'Semi' thwart. A lovely shape! A one off or maybe she's based on an old design like a Holmes. 'Grayling' rings a bell. Anyway take a look.

She's not far from a Homes Ethel.

Your images don't show.
If it was the boat on the website in your next post, the mast hoops say gunter or gaff, not lug, and I think that the position of the foremast and center plate are different. The planks look too wide for strip plank. Possible tight seamed carvel.

That is a beautiful effing boat!!

[Edward Pearson]

Grayling was an entry by Albert Strange for a small canoe yawl competition by the Humber Yawl Club in 1905. She came second to a design by Holmes. Can’t find any pictures of it, its not in Leather or Clay’s books anyway. Dunno if its any connection. I guess she might have been in the 1905 HYC yearbook. Be a longshot.

I initially though light carvel Nick but the planks look about 1 inch or so. A carvel guy would surely work wider planks? Not sure if she’s glued or not. I guess Aerolite was the small boat glue in the 70’s but wasn’t much of a gap filler.

'Poxy is for less than competent wood butchers.
Resorcinol Formaldehyde is a better glue, WBP that withstands long-term water immersion and has high resistance to ultraviolet light and all that.

That’s pretty much for how I work.

I wish Woodwind was 100%AYC. Her keel, frames,stem/stern are b but I switched to the volcanos knockdown fir for planking as an economy measure. Same story with all galv fastened. She will not be one of the two century boats. One perhaps though.
