compound curves in plywood

Does the cedar strip technique you mention use multiple layers of veneer?
Presumably you need a form to wrap this around. Does it have to be solid
or can you just use formers, say, every 9 inches or so? How do you clamp
to get a good bond between layers?

The web site I was looking at for a kayak.

Yes to your question of formers Their plans give you full size former
layouts that you cut out put on the plywood and cut the formers from there.
They then attach the formers to a central beam and proceed to lay up the
wood strips using whatever wood to get the design they want mostly cedar
with mahogany for designs. after they do the top half they cover with
fiberglass and epoxy. They then remove from the formers (you did use
waxpaper on the formers right?) and fiberglass and epoxy the inside.
They then repeat with the bottom side. Then you fit the two sides together
and apply fiberglass tape and epoxy to both inside and outside of the
joint.
Basically instead of using foam for a core they use wood strips.

As soon as I finish this KR-2 in my garage (about another 10 years) I'm
going to start on my Cape Ann Double Kayak!
