Phil Bolger once started builing a hull that way but gave it up when he
found out how much the adhesive was costing, and finished it the old fashioned way. You might want to cost out the project before getting started. There are more flexible adhesives than epoxy. You might look into some of them. I've heard of polyurethane being used on lapped strake (cliker) hulls. Seams above the waterline tend to dry out and open up while seams below the waterline swell up tight. If glued seams can't open as the wood dries the wood may split. TF Jones encoutered this after 10 years on a lapped strake canoe built light with thin strakes. That canoe was kept inside out of the sun when not in use.

This latter method is the usual treatment when a traditionally built carvel craft is reconstructed using epoxy adhesives as part of a full restoration program. Sometimes a thickened epoxy mix is introduced into the seams as an alternative to wooden splines and this seems to be just as effective in fastening the plank edges together. The planking is also glued to the spine and framework, which on new boats is built of laminated hardwood, glued and coated with epoxy. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-freenet email must have "notspam" in subject or it's returned |
