Actually the DF 48 has quite a curve about (10" or so over the 14') stern to the transom, making it quite kindly in following seas in comparison to some other un-named vessels. I saw one of Art's earliest vessels this summer and it was nearly canoe sterned. As the years progressed his designs became more contemporary, I'd bet Tad Roberts could educate us on the pros and cons of these two extremes.

I have found that throttling up to about 8.7 knots and 1900 RPM smooths out following seas giving the rudders additional bite so the AP can work more efficiently. Daddyo, you'd be amazed at what the active stabilizers do for roll mitigation on the DF 48.
