My 1985 Hunter 25.5 is rather tender in anything beyond, perhaps, 15 knots of wind even for me, a veteran of many years of performance sailing. I know that this particular Hunter model was available in either an outboard engine version or a saildrive version. My questions are: 1. Is it logical to assume that the outboard version, which is the one I have, is underballasted in consequence of the absence of the typical weight of a saildrive of about 120 pounds? and 2. Would a couple of sandbags totaling 120 pounds in the bilge make a real difference in her ability to stand up to wind?
