: 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

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.
