Ports
The ports in the back room are the same as the other small ones. As for the four larger ports in the saloon: I do not have them because I have the older version of the O'day 37. They are simple plastic sheets. I will replace those crazed sheets with new thick acrylic sheets. The main hatch in the the saloon also need reinforcing. I will also buy a thick piece of acrylic or polycarbonate (Lexan) for it (approx $50). Cut out the inner portion of the existing hatch plastic. Place the new full size acrylic sheet on top, caulk and through bolt. I will also reinforce the forward hatch with fiberglass ribs and paint over them.And yes: the 8" round port that I bought is by the galley facing the cockpit. It will provide additional lighting, help air circulation while cooking (needed), let us see what is going on in the cockpit while the hatch boards are down, and I think it looks good!
