Tom, the Potter/Moesly hulls for the post-1968 20' are actually 19'8". The Moesly 1966-69 19' hulls are 19'6". Later hulls are 20'4". Moesly/Potter hulls are generally a bit heavier, with 4 layers of hand-laid woven roving fiberglass.

As a SeaCraft dealer in '87, we were told that in order to lighten the hull by 200lbs, Tracker had decided to go with an outer layer of 8 oz. cloth, 2 layers of 6 oz. mat (aka "chop"), and 1 hand-laid layer of woven roving. I don't know first-hand if that's what they actually did, just the briefing for changes coming for the 1988 model year. I don't see why that wouldn't still be as strong as you'd ever need a hull to be, it's just different.

I remember as well both the Potter 20'SF and the Tracker 20' had exactly the same fore and aft CG [measured from the stern], despite the length difference and the fact that most of the Trackers had a 25" transom. (20" was optional)
