53s with TIs have the option of getting on plane (just), on a good day, with a tail wind, shiny clean bottom and if the overweight mother in law and fat niece stayed on the dock
... I think they burn around 40 GPH, but i could be off since mine is a Natural.
at hull speed, these boats are great... you can take them out, cruise 1/2 hr to your a nearby anchorage and come back for less than a decent restaurant dinner! And since they have great ventilation you only need to run the genny for air con at night.
last week end we were out anchored on the bay (biscayne bay). 90+ degrees but a 10kts breeze which kept the saloon cool (2 doors, and 2 windows) as well as the aft deck (ours is a classic, which unlike the ED has wing doors bringing a ton of air, even in summer)
You do about the same as I did with my Chris Craft at hull speeds, wish I could open up like you can for the air flow. I can cruise at 9.5 knots with the gen set running on about 10 GPH. I've measured that several times while doing an all day cruise, went about 120 nm one day and averaged 10GPH with the gen set, we needed heat that day and the admiral did some meals for us. Did one of about 80 nm averaging 8GPH but didn't run the gen set that day.
Mike I. you mention consumption at cruising speed, what do you call cruising speed for these?
