: Of course it depends on what kind of wood you're using-I was using
: western red cedar and Okoume plywood. Marine douglas fir plywood
: is significantly heavier, I believe.
: For my carbon fiber build I'm using 3/8" Okoume plywood except
: around the cockpit where I'm using 1/2". That will provide
: significant weight savings. Carbon fiber-structural foam
: laminate would be ideal from a weight point of view, but
: hopelessly expensive.
: I agree about ounces, and things like float bags and back bands can
: add a surprising amount of weight.

The skin can also be a big weight factor, especially on a folding kayak. My 17.5' X 19" Sea Rider wood frame non-folder
weighs 23 lbs due to WRC stringers and a clear vinyl skin.

My 16' X 21" Sonnet folder weighs 18.5lbs due mainly to it's lightweight 10oz PVC / vinyl skin, minimal aluminim stringers,
and no HDPE. Many commercial folder use 36oz or greater weight skins, hence their much greater weight. Tom

18.5lb Sonnet 16 .... Simple is as simple does !
