Topic: engine compartment hatches
My contessa does not have an inboard engine and I don't plan to put one in. However I would like the access hatches for easy access to storage. Someone previouse to me has semi permanantly sealed off the previouse engine room access hatches in the cockpit by laying a heavy bead of 4200 sealant around the edges and screing the hatch covers down. I am removing that now cuz I'd like easy access to that storage area, was wondering how it is usually rigged for boats with engines where it is sealed from water that comes in the cockpit but also easily accessible for engine service.
What kind of gasket and fasteners are used to keep the hatch down and water tight while remaining removable when needed?
