: I recently finished glassing my strip deck.
: It is western red cedar.
: I did the top first of course, let it sit for a week to cure.
: Then I pulled it off the forms and flipped it over to plane the
: underside and glass, then cure.
: After finishing this step I placed the deck back on the hull
: and found that the shape had changed dramatically.
: In essence the curve of the deck from shear to shear is much
: larger now and dose not match the bulkheads.
: To get the outer edges of the deck to touch the shear strips
: I have to use a strap clamp.
: So my question is;
: Should I stress the deck over the bulkheads or should I
: reshape the bulkheads to fit the shape of the deck?
: I have not cut my hatches yet.
: If I reshape I will lose 1" of height at the top of the front bulkhead.

Usually on a deck and/or a hull I use a strap, spreader, or other device to hold the hull/deck at near the correct cross dimension while working on the inside. It doesn't have to be on there all the time, but does need to be installed while the inner laminate cures. All is not lost though. Nothing ever works perfectly. As long as you can use the strap clamp, banding, rope, clamps, duct tape, etc. to get the hull and deck joined while you apply some tape on the inside you should be ok.
