Subject: Re: [Star45] Fiber glass vs just sealing the boat

Based on the damage to Phil's boat at the blackwell, I would not recommend
a bare balsa hull. If glass is hard to find, use pantyhose as your
fabric. You should seal the hull with epoxy and the glass adds a small
amount of weight.

my next boats are going to be 1/16 ply sides, 3/32 cedar bottoms and then
a .5 oz layer of glass over the bottom. I think the sides should either
be ply or have glass to prevent punctures in the case of contact. Decks
will be 1/64 ply that is painted. The decks are weak and if I get hit
while heeled over I could get holed, but that is a risk I am willing to

My boats with the two layers of 3.2 oz glass over balsa have held up well.
They have been hit and the damage has been limited to the deck where the
rails flexed when hit.
