Bye bye troublesome little splashwell........hello bottom of hull.
I opened drains from all closed off inner-hull areas to the bilge and all bilge areas drain here at the rear bilge. I have two special made St steel thru-bolted garboard drains for out of the water and two rule 1100 Auto bilge pumps while underwayl Should take care of any pesky "water in the hull" problems.
Note. Most small boats have their decks at or below the waterline and the use of scuppers for draining is just not functional. Typically it even allows the seawater to come in rather than go out. Looks good on the trailer as a selling point, but they just don't work. I eliminated mine and provide adequate pumps to handle any water entering the boat.
