baitwell hatch problems?

[aaron]

Salmon season started yesterday, and I,m still working on the boat. A sc18 1976.
1) Is there a bulkhead on the fwd side of the of the fwd wall of the baitwell?
2) I'm looking for a watertite hatch for the baitwell. 24 x 27 O.D. The closest I've come is a 19 x 27 od but only has a 14 x 22 opening, not very big. I'ts from anchor hatches in canada. West Marine, Freeman,bomar, tempress were all dead ends for me.
3)Do I have to build one myself?[LIST]
