I couldn't even guess what a tankful of fuel would cost on that thing and how long it would last. Probably more than my mortgate, for the whole year!

That's an old strategy for beating the theoretical hull speed--much as modern catamarans and high-speed ferries do. Shape the hull to slice through the water, power up, and let'er rip! Now, if Frank had just made our boats with about 3' of beam (and a 10' deep bulb keel to compensate for the loss of form stability), who knows?

Fuel? As P.K. Rigley used to say, "If you have to ask, you can't afford it."

The old formula 1.34 x square root of waterline length yeilding max hull speed in knots ASSUMES a variable called the Prismatic Coefficent is in a normal range. That is a measure of how long and pointed the hull is. Bulb bows on big ships lower the PC. Knife like catamarans and the boat in this picture have a much lower PC.

I would guess a fillup on this boat costs between $50,000 and $100,000 (25 to 50 thousand gallons). You know you've got a big boat when you start measuring the fuel in tons.

Guess about 5 gallons to the mile, yeilding a 10,000 mile range.

A "Captain" on a boat like this is more like a CEO of a small, international, company than a boat driver.
