Our CT 35' Sundeck Trawler has a swing out hatch window right in the center of the wheel house. The hatch is fitted with a groove to accept a gasket designed to go around the entire grooved hatch to waterproof the hatch when closed and dogged down. This gasket has, over the years, flattened out to the point of being useless. I've used the usual stick on gasket material to attempt to waterproof the hatch, but I still get leaks in a good rain. Does anyone know a source for this type of hatch gasket? There is no name on the hatch, and, being a Taiwan Trawler, it's an unknown manufacturer. If anyone can help with this, your karma level will rise accordingly. Mahalo.....
