Arguably, I'm spoiled. On my C28, I had a M25XPB and on the C34 we have the M35BC. In both cases, I've appreciated the boat speed we were able to maintain in 20kts of headwind with the sea state to go along with it. In both cases, we happily clipped along at 4.5-5kts. I attributed it to both boats being slightly overpowered for their size and weight. I wonder how true that is, though. Of course we're talking theoretically, but I wonder how much different it would be with the M25 in the C34.

My 25XP has power enough for my tastes. At 2800 RPM it easily reaches hull speed in smooth to moderate sea state. As Stu said any more power it just buries the stern. Of course that may be a function of my 3-blade flexofold 15x10? Also, my experience on ALL boats is when powering into 20 knot winds and related seas, one should slow down anyway—-less pounding, less green water over the boat, etc.
