I'm building an all composite sea kayak with kevlar as my main reinforcement material. I'm using 5 oz kevlar, how many layers are necessary for the hull? I've heard that it's strength is comparable to 6 oz fiberglass cloth, how many layers of that would I need? Is it necessary to cover the outside of the hull with glass to protect the kevlar and get a nicer finish? I was thinking I would use 4 layers of kevlar for the hull and 3 for the deck, and maybe cover that with glass cloth if necessary. Would that layup be strong enough? Or is it necessary to use 5 or even 6 layers. Thanks
