I had an 1970's vintage 23 Seacraft that nearly sank as the result of leaking through hull fittings. The factory installed through hulls were plastic that were set in place with some type of caulking. Eventually they would start to work loose and leak with unfortunate results if the bilge pump failed. After figuring out what was wrong, I replaced all through hulls with brass ones and never had a problem.
I also know of a late 80's vintage one sinking while anchored in a storm as the result of water coming in throught the rear scuppers and getting into the bilge through a hatch in the deck that was not sealed.
The Seacraft that I owned had the rear drains going through the deck. While they were a pain in that you got your feet wet, that weren't a factor in Seacrafts sinking unless they bacame loose and started to leak.
