Forward Hatch Info
This is the info I have for the hatch over the V-berth:Bomar “low profile” model.Hatch No.: 1039-10AX, Hatch opening 19-1/4” x 19-1/4” [verify dimensions and model number]Note: Original replacement hatches for an 1988 boat are not available due to a fire at the factory that destroyed their tooling and engineering drawings.Installation: The radius of the new hatch is slightly greater than the old one so you'll have to fill in each of the corners with a bit of fiberglass.Bomar, Div.
