: Hmm, in the equation I've got 2*3 square meters for the surface
: area for the fibreglassing and just the one 3 square meters *
: the wood density for the contribution of the wood weight. Like
: you say it's the attachments, coaming, hatches, fill coats,
: second layers of fibreglass etc etc that all adds up.

: It's interesting to just play with the epoxy contribution - you
: really have to lift it to make the weight go up.

3 square meters would be a tiny boat.

You're generally lucky to get 60/40 epoxy to glass ratios btw doing hand layup, usually not even close to that specially when you first start using it.
