Schooner planking photo

It looks like they are double planking and gluing the layers together with 5200. Is that what it looks like to you?
Are they then cotton caulking the outer later?

Yup. That's what it looks like. Who'da thunk it?

The Hereshoff Bounty replica that was built for a client of mine was built using that method, 'cept 3M 4200 compound was spec'd. It has lower tensile strength and was selected so that there would be some possibility of getting a damaged plank off without power-planing it away layer by layer. ;) :D

We saw a Garden trawler yacht being done this way at French & Webb in 2000. I asked them about it. It's not a new idea, but a variation on an old one where lead paste and felt would have been used instead of 5200. They were building to owner's specs, but didn't seem to have any qualms about doing it this way. If I understand correctly, it was a popular method at Herreshoff Mfg.

Only the planks below the waterline are caulked, I suppose to allow for movement. Nice pics.

That Garden trawler yacht was being built for Bill Page, one of the founders of Cannell, Payne and Page Yachtbrokers. If his experience with wood boats lead him to request that type of construction I imagine it was a dependable method.

I don't get it, if your going to use 5200, why not just use epoxy? :confused:

How about ...ones flexible ,one's not.What a mess to get on your tools !

[sdowney717]

The flexibility issue has to be the reason for the 5200. Epoxy would lock the wood together and the only way to allow for movement with epoxy is the wood surface would have to tear free. I once saw where an owner routed down the plank seams 1/4 inch wide to create clean seams and then filled them with 5200.
