: Unless you've got alot of experience using advanced composites, it

: have the compression strength that the wood does and that
: fabric/glass is the heavy part, the wood is actually very light.
: As you mentioned it would also be very expensive.
: Foam sandwich construction can be very light on a bigger boat, but
: as you get smaller the skin weight gets to be a higher
: percentage of the weight.
Ah, I see your point. I hadn't considered the weight ratio for the skin on the smaller craft.
: Fairly easy btw to have a sub 30 lb. 17' kayak using wood strip,
: very difficult to match that using other materials other than
: plywood with S&G.

Thank you for the info, I'll have to reconsider strip and s&g methods.
