Hi Eric,
The sea kayak is being built in a mold i acquired via eBay, not sure of the design, but about 17' long and quite high volume - which suits me at 6'2"
I built a very light polyester / chopped strand boat from it a couple of years ago which paddled beautifully but regrettably sank on the Solent during a trial paddle, however i did get enough paddling in to convince myself that the design & mold where worthwhile, so I am prepared to invest some better material in another boat
The mold is in 3 parts, a forward and after deck section, and a 1 piece hull. Progress so far is to make the two deck sections, Layup is: Polyester gel coat, then 200g CSM & 450g carbon bi-ax infused with epoxy. I've not been able to balance them on my scales, but i estimate about 5-6Kg total for the deck.
Hull will be Gel, 200g CSM, 300g e-glass twill, 3mm PVC foam, 300g e-glass twill. with some carbon UD down the center and along the gunnels. Biggest challenge with the hull is working out how to fit it into the garage, I've acquired a couple of extra machine tools since i built the last one...
Sorry no pictures, lost them when my last phone died
