Yup, at 2800 rpm ford lehman 140hp in a flat sea with a clean bottom, Nauticat themselves give fuel consumption figs up to 13knots, never done that though.
Optimum fuel v speed for Beleza seems to be 9.5 knots. When I brought her down to portugal non stop, liverpool to Lagos, she motorsailed most of the time and we averaged a tad over 9 knots logging 1350 mls in six days used slightly over a Gallon an hour when the motor was on and used under a quart of oil. Beleza has a 22 inch three bladed prop.
She's a heavy boat but seems very slippy through the water, the transom stern helps. Also she's schooner rigged so rubbish to windward but a real witch with anything on or abaft the beam.
I love that boat to bits. Say what you like about motor sailors, carpet slipper sailing, old mans boat etc etc. I know when the going gets rough I reef down, shut the doors, turn on the wipers and put the kettle on. My wellies have gone moldy with lack of use, my oilys only get used when going ashore in the dink.
I've done the rough stuff, now I want comfort.
Some thoughts (facts actually).
Consumption of little over than a gallon per hour means engine output of around 20hp.
12 knots for a displacement yacht mean 24.5 m or 80 ft waterline.
