Agree you need 2330 if she were my boat. We surveyed a 54 with C12's out of FLL 2 months ago and she was advertised to cruise at 16 knots. 19/20 wot. At 1950 we had 12/12.5. WOT was only 2220 When we stripped off the prop speed we found the props had been damaged and repaired multiple times. New set of Veems 3 weeks away. The new props are set to give us 2320/2340 wot. These Offshore 54' struggle to get up and trim off anyway so everything has to be 105%.
