What's the easiest best way to replace the hatch forward of the mast? I would like to replace the entire hatch including hinges and have something a bit more substantial than just pressing down against some weatherstripping on the deck.
Try Mark Plastics in Irvine, CA. They made all the original windows and hatches for a variety of boats built in CA and are still in business. I had all the windows on my 1978 B30 replaced about 4 years ago. Called up the company and ordered the frame type and plexiglass color and they arrived about 4 weeks later in a wooden crate. Great service. They are listed on the web although I don't believe they have a web site.
