glass tape for an optimist
Hello--
I'm building an optimist dinghy for my son out of okoume plywood. He'll be racing it, so its important that the boat come out at the class minimum weight. Can anybody recommend a glass tape (and supplier) to use on the seams? I want something light weight that won't soak up a bunch of epoxy. This is a tiny boat (7.5 ft) sailed by kids, so loads are relatively light. Thanks for any advice! Jack |

I wouldn't go to 4 oz. You'll save more weight by being tidy, using small fillets and only enough resin to wet out the cloth. Consider wetting out dry lengths of tape on polyethylene sheeting and transfering to the boat; excess resin is left on the sheeting. -- Evan Gatehouse you'll have to rewrite my email address to get to me ceilydh AT 3web dot net (fools the spammers) Thanks for any advice!

Some ways # use lite weight (thin) glass cloth wich will absorb less epoxi. (all waeves are intended for ~55%weave - 45% matrix # use not as wide tapes.... Less glass weight = less reinforcement. not as wide tapes = possible delamination. AND ...the chines are the most stressed part of a hull and because of that THIS is the most stupid place to save weight! Morgan |

Jack ------------------- use 3 inch wide tape - let the weave of the cloth show thru instead of trying to 'hide' the cloth weave with coat after coat of epoxy... I've also just taped the outside of similar small boats and left the inside untaped (but still smoothed with a fillet of thickened epoxy). paul oman www.epoxyproducts.com/marine.html |
