I have a 1989 Pacific Seacraft 31. It has two water tanks. The bow tank has a plexiglas cover over the entire tank that is siliconed in place as an observation port and then a loose plywood cover is fitted over the plexiglass.
However, on the aft water tank the plywood cover is also siliconed in place on top of the plexi-glass. This eliminates the ability to view inside the tank. This tank leaks from the top when on a starboard tack despite having both the plexi-glass and plywood panel siliconed in place.
Of course the easiest solution is to never sail on a starboard tack . . .
, but we are looking for a better solution. Any suggestions on how to separate a phywood panel from silicone and/or a better sealant. The leak is on the port side midway on the full curve.
