This is a pretty wild stab and anyone who has actually lived with one of these boats may come back with a different conclusion that has a lot more validity than my supposition.
7000 lbs of ballast in a 15200 lb boat is a reasonable ballast ration taken in absense of any other info. 4.9 feet is a little shallow for a 37.2 foot boat or a 21 foot waterline length. (For comparison, my 38 footer with a 32.5 foot waterline is the shoal keel version at 6''4 and the Beneteau First 38s5 with a 31 foot waterline and similar numbers to your boat has a 5''5" draft for their shoal draft versions. I cite both of these because they were in production about the same time as the 372, but that said the Beneteau was intended as more of a coastal cruiser while my boat was specifically designed for offshore use.)
The other aspect that comes into play on a boat like the 372, which has an interior that is really optomized for coastal cruising, is that much of the storage ends up being high in the boat. As you load up with cruising stores the boat''s displacement will increase pretty dramatically, as much as 3000 to 4000 lbs, and much of that is high in the boat. Now you have an 18000 plus pound boat with 7000 lbs of shallow ballast and that is not too good.
One other concern that I would have with the shallower keel is motion comfort. A deeper keel goes a long way toward dampening a boat''s motion, and a deeper keel''s lower center of gravity goes a long way toward increasing the roll moment of inertia, combination of which means a slower roll rate through a narrower angle and reduction in the tendancy for excitation rolling. Its one thing for a boat that was designed to be shallow to begin with but these boats were designed for a deeper keel and the shoal draft is something of a popular adaptaion.
