Ron, I have a 1995 Oceanis 440 that has exactly the same problem. I've tried Vaseline on the gaskets, but without much luck. It appears to me that the seals between the gaskets and the plexi are quite good, but that the water is coming in through the frame of the latch itself. I haven't found the time yet to experiment with my boat, but I suspect that once we find the right spot, it will take a very small amount of well-placed silicon to fix the problem.On the plus side, the boat otherwise seems to be VERY dry. Even after heavy rains or tropical storms, the bilge never accumulates enough water to trip the bilge pump. During the dry season, I've actually found the bilge DRY!
