Just bought my first sailboat, I decided to gut her to redo the mahogany,wiring, etc. The main hatch is rotted and it isn't the original. Anyone have the original drawings or has anyone replaced one with fiberglass? Also my forward hatch is fiberglass, is this the way they were manufactured with one fiberglass and the other wood? 2nd question and I've read some opinions as far as cleaning the interior fiberglass, seems as if bleach is going to work the best. As any one tried 'On & Off'? Since the interior is striped to the fiberglass caution as far as damage to other surfaces isn't an issue. Thanks Don
