How self bailing is a V20 ?

[throwback]

The early boats including my 76 is not self bailing in fact damn near lost the boat about ten years ago bilge pump died while moored at dock boat had about 8 inches of water in boat after a storm; covered starter and got into outdrive from inside. Have since installed two batteries and a 1200 gallon per hr pump but still do not leave boat in water for any length of time. Thought about installing scuppers at deck level in boat but not sure they would be high enough above water line. The boat needs a bit of TLC and am building a new 34x30 shop this fall. Plan to rebuild boat over the next year of so which will include replacing the deck, paint, new hardware and installing floatation but still at not sure the hull can be made totally self bailing.
