4mm Ply Glass Weight

Postby J_delabere on Tue Dec 12, 2017 6:16 pm

Hi All,

There has been previous discussions on fiberglassing the bottom panels of timber Sabres. Most people suggest 2 Oz. Cloth which when I convert to gsm is about 65 gsm? This sounds very light? Is this correct?

Hi James

I just had my first few sails in my newly built Sabre (2074) which was constructed with 4mm hoop ply and 2oz glass inside and out. The hull seems fine, no sense of it not being rigid enough, or that I am going to put a foot through it.Pretty sure this the same combo as much larger Jarcats etc.

Cheers Chris
