: This group is into everything. There were discussions and commentary on the
: performance of the "Walrus" some time ago. If you have time go
: into the archives and do a search. It's all in there somewhere. Someone
: even recalculated the forms so you don't have to waste all that plywood
: with the tall ones Puttz designed.

A neighbor built the Walrus from the George Putz book quite a while ago . He was a beginner , fished from it even , so it had to be stable. He liked it very much but I recall him saying it was suffering from breakage to the side trusses.

I would use plywood forms rather than Putz's method . It will be much lighter in weight and just as strong. Tom Yost has some very good designs and ideas on his website. Don't mean to put you off Putz's method as it does get you a kayak.
