Cruise and WOT C28

[JamesC28]

Now that the boat is loaded up...

We use our 2013 Cutwater 28 for day trips and a few overnights.
These numbers are for about half full of fuel and water and 3 passengers and plenty of alcohol.
We are on the Chesapeake bay which is brackish
The bottom is clean, I added drop fins and the prop has been coated with PropSpeed, these two things made a HUGE difference.
D4-260 has 400 hour.

RPMs, Knots, gal/hr, nm/gal
