My 24,000 lb Carver 35' ACMY (40' LWL) Cummins diesel holds 330 gallons in 3, 110 gal tanks.
At 2300 rpm and 19 kts I get 1 Nmpg
At 1400 rpm which is displacement speed, I get 1.36 Nmpg and 8.3 kts.
Single engine at 1400 rpm I get 2.5 Nmpg and 7.2 kts.
There are many no wake zones in FL and I usually cruise single engine when in these zones, swapping engines every 20 minutes.
However I figure on average 1.5 Nmpg and with a 25% reserve that gives me a range of 375 miles. This is probably a little optimistic however. Admiral likes to go fast with comments like "We're not on our sailboat anymore"!
We cruise the intercoastal so have no real need for long range capabilities, fuel stops are generally less than an hour away. Besides this is no blue water boat.
