There was a water line 6" above the cabin sole aft. That's because the cabin sole is literally on the bottom of the hull. The owner had built some kind of coffer dam into which he installed one of those Rule aquarium pumps (which is about all they're good for) to try to solve the problem of there only being one bilge pump in the boat, and that being located under the engine. Of course, when you slow down suddenly, all that water in the bilge which the pump won't remove runs forward and . . . .well, you know. Messes up the carpet a bit, among other things. here
