Sailboats do roll more than most trawlers but it is not entirely due to lowered VCG. Sailboats tend to have slack bilges and less form resistance to roll. They have higher ballast ratios which may give them a shorter roll period when the mast is removed. A partial solution to the roll problem would be to keep a stub mast capable of flying about 100 sq. ft. of sail. When sheeted amidship, this would serve well as a roll damper. The boom could be used to raise a dinghy. If the mast height does not exceed 17 ft. you could pass under all of the bridges and transit all canals on the Great Loop. (I may be a foot or so off on the height limit.)
The Willard 30 is a similar boat to the Watkins 27. The same hull has been used in motorsailers and trawlers without alteration. Willard owners complain of roll, but no more so than owners of similar sized trawlers. A boat under 30 ft. is too small to fit active roll dampers. There are no complaints about the Willard's seaworthyness, however.
A sailboat to trawler conversion is quite practical and several members of this list are cruising in coverted sailboats.
Regards,
Larry Z
