Title: glassing 11' hull
Post by: tobyker on July 22, 2010, 11:39:21 pm
I have an 11' long canadian canoe with a lug sail. I am very pleased with the hull shape but it has been kept out in the open for some years and the ply is starting to go. I'd like to cover it in grp and remove the ply, so I end up with a grp hull. I will glass some stringers inside when the ply is out, but can anyone advise me how many layers of what weight cloth I should use for adequate strength/rigidity. (I know I ought to make a female mould and then lay up the hull inside that, but the shapes are not right - plumb bow and stern, and I'll never get the plug out in one piece.)

is there any reason why you cant make yourself a female plug from your male hull ? it would make your life a lot easier to then make a two piece mould , you could then build a more to sell on to help recover some of your outlay !

VMT oldiron - one of your links suggests leaving the ends open to be finished off later, so you can get the canoe off the mould - brill idea! And another suggests cloth weights. Think it may work!
 Jon, I'm lazy and want to get a boat quickly - If I can get the cloth off without breaking up the hull then more might be a possibility but I don't really want to go into production!

Hello Tobyker, It may be easier to hire a canoe mould, save you a lot of work and aggro. They may tell you what the scantlings are for a given hull.    Nemesis
