my v is a 1974. It had the drain to the bildge floor. I ended up raising my floor about 1 inch throughout my build between bring the stringers up a little and using 3/4 ply instead of 1/2 inch. I absoulutely refuse to own a boat that drains into the bildge, the thought of it make me nausias!!!! lol!!! so what i did is completely sealed off the bildge from my deck I want her to ultimately pop up like a cork if shes swamped, I want the water to roll out of the transom. If you look close at this picture you will see I converted one of the old fish boxes in the floor to a sump well in the rear were a 1100 gph rule pump will relieve the deck of annoying wash. I also included ball scuppers on both sides with brass tubes incorperated so they be plugged up when on the hook and plugs pulled when on plane and trailered at the house. there will also be a 16" inch wash board that will span the deck port to starboard that is removable.this wash board will also keep transom wash off of the main deck and inside the "sump well area" so the bildge pump can remove it over board. so my deck is almost a hybrid of many styles. And of course I will have a 1100 rule and a 800 rule below deck with a high water alarm. I just didnt see the point that if one did come over the transom why I would want it to drain into the bildge why not make a sump in the rear to drain it off the deck. and the odds of you recovering after taking a good size swell over the rearend of the boat is isnt all that great. you really need to react fast regardless of how big your pump and scupper holes are. just my opinion.
