Re: Material: Composite sandwich with foam?

: Unless you've got alot of experience using advanced composites, it
: will be very tricky using foam and it'll likely be quite a bit
: heavier rather than lighter. Strip built can be very light. You
: need much more fabric if you use divinycell since it doesn't
: 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.
