: I have a mold for a 18 ft kayak and I'm looking for imformation on the cloths
: and fiberglass mats that are the best to use to make a light and strong
: hull with polyester resins. The number of laminations of material needed
: with out using carbon or kevler.

The mold for the fiberglass kayak is built to a steve killings design and it was built by myself and friends strip planked and covered with 6oz cloth and faired with long broads. The mold is a male mold and if the frist boat turns out good we are going to make a female hull and deck mold and start useing gelcoat in the lay up. The frist hull was pulled off the mold yesterday. The lay up was two layers of 10 oz cloth and two layers of mat. the hull is stiff but still has give and weights 30 pounds which isn't bad because the store bought boat weight 60 pounds. the deck is going to be layed up of one layer of 10oz of cloth and two of mat which will be lighter then the hull. So hopefully the kayak will be around the some weight as the store bought boat. I will post some pictures soon
