Re: Kit kayaks....

I've built two Pygmy Coho's. I've generally been happy
with the construction of the kayak. I think their directions fall a
little short regarding seats and hatches, which are almost treated as an
afterthought.

My general attitude, I built it, I can repair it.
There seem to be several friend of friend stories that the the wood 
composites are pretty tough (surviving falling off racks at highway
speeds, etc.). It is pretty amazing how a bunch of long thing
strips of plywood can come together into something that tough.

Strength depends in part on how well you build the wood composite.
Scratches you can sand out or fill with epoxy or varnish. 
In fact Pygmy assumes the bottom strip of fiberglass along the 
keel may need to be replaced from time to time as it gets scratched 
up by landings.

It is possible to split a seam, I know, I did it when trying to install
a bulkhead that was a bit too big for the interior dimension, but repair
was applying more tape, fiberglass and sanding.  I was also putting a lot
of force on the seam, essentially forcing a wedge inside the hull.
Strength seems to be as good as the fiberglass, and in theory, less
brittle with the wood core than a pure fiberglass.

You can make it tank like, both in weight and strength by multiple layers
of epoxy and glass inside and out, or you can make it more lightweight, 
and a bit more fragile by reducing the weight of glass cloth, and where 
or how many layers you add.

They are rigid, like fiberglass kayak.
