hatch leaks, foredeck and lazarette

We cut out the original Cal 40 hatches and glassed in  short pedestals that are about 2 inches high at the outboard edges and absolutely flat on the top.  We then installed Lewmar hatches on the short pedestals.   They have been perfect and leak free for 28 years.  We lubricate and clean the rubber seals every few years with some silicone grease.
