My old Victory 21 had a foam-filled buoyancy tank in the bow, and some foam under the cockpit sole. Whether it actually had positive buoyancy or not, I don't know. However, since fiberglass is only marginally more dense than sea water, and wood is a bit less dense, you really only have to worry about providing buoyancy for the ballast (be it lead, iron, or whatever). Generally speaking, for a 2000 lb boat, you probably only need a few hundred lbs of floatation. Five cubic feet of closed-cell foam should provide about 250 pounds of floation, which may well be enough for most boats of that size (but, you would have to work out the actual numbers of course).
Never forget them. Do something to prevent it from happening again.
