Heh. I was reading one of my zillion magazines the other day about a
62' Hatteras that was being built with twin 1200 hp turbocharged MAN
12 cylinder diesels - supposedly, it was able to do something like 50
mph.

I can't imagine what the fuel bill would be.

===================================

It's fairly easy to make some estimates.

2400 total hp, typically 2/3 at full cruise = 1600.

Figure about 1 gph for every 17 hp = approx 95 gph.

Estimating 30 kts cruising speed, approx 3.2 gals per nautical mile.

Those are pretty typical numbers for big planing sport fish and motor
yachts. It would certainly add a few dinero to the fuel bill for our
5,000+ NM this year. But if you're paying something like $2M for a
boat like that, what's another $50K/yr for fuel I suppose.
