I was wondering if any other 44 owners could share their experience with boat speeds they can obtain while under power. I absolutely understand that there are many variables including prop, bottom condition, current, etc.
We have a 2005 44AC with a 4JH4E Yanmar (54/56HP). Max engine RPM is 3000 RPM per the nameplate. I have a fixed 3 blade prop that as I recall is 18 x 12 or 18 x 13. I can get up to about 3150 RPM at full throttle which would seem to indicate that the prop is sized correctly. Best speed that I can get is about 5.5 to 6.0 knots full throttle with a very small chop and little or no current. I'm in the neighborhood of 5 knots at 2900 RPM.
I was motoring alongside a friend last weekend and his Beneteau 393 passed me as though I was standing still. I always suspected that the boat was slow under power but it never bothered me until this season.
