Coming from express cruisers which have a low center of gravity, I did expect a huge difference in Navigation when I switched to my 66SS, with the enclosed bridge. Plus I had always heard bad comments about the way Ocean boats ride with following or quartering seas. However, this boat has me steering like crazy to prevent it from yawing and rolling excessively with following seas, even with smaller waves. It is just scary at times. I don't know if this is something normal with sport fish boats, as I've never owned one before, or if my boat actually has some stability issue. I know that having 1300 lbs on my fwd deck (dinghy and jet ski) doesnt help much, but you would think that this wouldn't affect a 88,000 lb boat much. The other thing is that I do light cruising so I only carry about 20% of fuel every time I go out, maybe the lack of weight amidships and on the stern could also be an issue. One thing that keeps me calm about this is remembering seeing a Bertram 61 cruising next to me when I had my sea ray 54, on following seas, and the guy started rolling like crazy and had to slow down while I was able to keep cruising at good speed with little roll. So it makes me think that this could be a normal issue with Sport fish boats with flybridge, which have a much higher center of gravity??
