Cabin work

So how to attach a foam/carbon cabin to a plywood deck?

The easy way is to tape the inside and outside joint and then fair the tape, but I want to avoid as much of the overlapping as I can by getting some of my primary fibers to also serve as the bonding flange.

First, a clamping caul to the approximate shape of the deck cutout.

Packing tape on the deck, then peel ply, with the top layers of peel ply and absorber ready to go.

One layer of 17 oz. biax getting pressed.

There's the boat-shaped flange.

Gluing the cabin onto the flange.

And here's the cabin all laid up. There's one layer of 9 oz. uni running side-side (and onto that flange!), with some local reinforcement around the hatch opening, around some future hardware cutouts, and lots around the mast step.

I plopped the whole thing on the ground and stood on it- it's bombproof, and that's without having the sides restrained from flexing outward by the bond to the deck.

So the plan is to tune up the deck cutout, trim and sand the flange a bit, glue the flange to the deck, then add one layer of light tape to the underside of the deck/cabin joint.
