OK, maybe a stupid, basic question, but how is a boat actually designed as far as the bilge area is concerned? It seems to me that my 19' bowrider has a bilge area that's sealed off from the rest of the boat and is basically just a place to collect water that enters the boat from the top. Unless I haven't looked close enough, shouldn't the bilge area be the lowest point in the boat where the entire boat (even under the floor) drains to???
