One of the few drawbacks to our Aphrodite 101, Averisera, is the low main hatchway. If we swamp, a lot of water can make its way quickly into the interior. Our hatchboards are fine for near coastal work. We have stress-tested the boat's ability to swamp and recover and find ourselves satisfied... in a general way. Bascally, Averisera is hard to lay over on her side and swamp. A wave breaking over the side is another matter. With low freeboard, a boarding wave is very likely. That is the problem to solve.
The cockpit must be improved in a few ways. One is to improve the height of the "bridge deck" or entrance sill. Another is to add cockpit drains. The engine hatch in the cockpit floor is a whole other matter.
Here we are at the end of October 2014 and I measured for a hatchway revision. I think a securely fastened and caulked plexiglass slider will do the job. The height is not too much inconvenience.
