Yes something like that. Although of course it is easier on even bigger boats (like the Skoota 32) to make a half hull mould so you can access all the mould surface from the side. You don't want to get in the mould if you can help it. Most production boats are on swivels so can be turned left and right. It isn't realistic to do that with a temporary mould

I actually also use a release agent when laying up the first moulding, just to be on the safe side, you don't want any stickups.

As I have said elsewhere on this forum, and I am sure Jacques has said many times, you cannot use regular gelcoat with an epoxy laminate.

Just to clarify, the only exterior joint you need to make is the joint between the two half mouldings down the hull centreline. And there is a rebate along that joint so even after making it the glass is below the hull surface so it is easy to fair. People use thin ply or even layers of packing tape to make the rebate
