: It looks like the next project is a strip--built version of Gardner's
: Lincolnville salmon wherry in *Building Classic Small Craft.* I know
: others on this board have attempted similar projects. Any comments,
: warnings, etc. would be greatly appreciated. My one particular concern is
: how many if any ribs I need to keep the sides from collapsing inward. My
: initial thought is to install ribs as in the original after both interior
: and exterior glass are applied but to attach them with glass and resin
: rather than screws or nails. Thanks, Tom

Tom,
There have been lots of quite large boats built in cedar strip/sheathed construction. Most larger designs use strips that are a bit thicker, say 3/8 or 1/2". Sheathing inside and out negates the need for a lot of the internal ribs. The internal structure can be that which is required for the seats, floors, centerboard case, mast, etc.. the various knees, the breasthook, guunels, etc., should be enough.
I think that Glen-L marine has a strip built wherry type boat. You might have a look at it to get an idea as to how much you need internally.

There was a Haven 12 1/2 sailboat built in the UK. An article was done on her in Watercraft. The Haven is a 16 foot Herreshoff boat, redrawn by Joel White. Originally intended for carvel planking, this one was done in cedar strip. The builder used 1/2" strips. He stated that the ribs were not needed (the original has some 24 frames), but some were added for cosmetic reasons. Of course this type of boat has a few bulkheads and other necessary framework, that made her plenty stout. Selway-Fisher has strip built canoe yawls that are 18 feet long and 5-6' abeam. Anyway, she can surely be built in cedar strip and would certainly be beautiful.
A.C. Gondola, of NortWest Marine design, www.nwmarinedesign.com , has several plans for large boats in cedar strip/sheathed constuction. It might be worth it in the long run to get a little consultation from an N/A who is comfortable with this type of construction.
Have you given any consideration to doing a glued lapstrake version? Duck Trap woodworking has built some Lincolnvilles and others in glued-lap plywood construction, and they have a manual covering their methods. Strip built boats are beautiful, but to my eye, it is hard to beat lapstrake on a wherry. Glued lap will save time over strip construction and will be lighter than traditional construction (as will strip built), and will take trailering/wet/dry cycles much better (than that of traditional construction).
Good luck.......sounds like a great project.
