Carver 500 CPMY Fuel Consumption

[FloatyThing]

I know there must be some of you out there with a Carver 500 series cockpit motor yacht (years - late '90s) as this is a very popular boat. Would someone please share their knowledge of fuel consumption? I do know that this yacht cruises at approx. 20k. Also, any other interesting info in general regarding this model is appreciated as I am just learning about it. Thanks in advance!

If you know brand/model/horsepower of the engines, you might be able to find performance curves, including predicted/nominal fuel usage at various RPMs, from the manufacturer's website.

I'm just guessing ,but, I would say that a carver 50 at 20knts would probably burn 60gph. I have alot of experience with sportfishing boats and speed costs dearly.

If it helps for comparison, I usually state our "cruise" at RPMs, not speed. Happens ours is usually approx 2200 RPMs (approx 85% of WOT) and I think that works out to about 13 GPH per engine (Cummins 450Cs) according to the manufacturer's performance curve. Our speed at that rate usually ends up around 19 knots, depending on wind, tide, current, load, the way I hold my jaw, etc.
