Hi Osp, no, that can't happen. the floor of the cockpt is 18" above the waterline. the saloon floor is on the waterline, the bilge below the saloon floor is apx 3 foot 6" deep - engine under saloon.
Battery box (1000 Ah) is fully waterproof - for'ad with snorkel system for vents. to provide power i an emergency for pump systems. plus, of course

manual pumps..
The dump to cockpit in emergency seems a logical idea to me ?
