I read somewhere that the QE2 gets 6" per gallon.- Hide quoted text -

Which probably translates out to be about a gallon per piston stroke.
Maybe more!

Fairly easy to figure out: At 20 knots they are doing approximately
6000 x 12 = 72,000 inches/hour. If they are burning 1,000 gallons per
hour which I believe is in the ballpark, that would be 7.2 inch/gal
which jibes pretty closely with the 6 in/gal stated previously.

What we don't know is what RPM the engines are turning at, the number
of pistons, and whether they are 2 cycle or 4 cycle - all of which
would impact fuel per power stroke. Just for grins, let's estimate
720 RPM, 10 pistons and a 2 stroke engine. That's 12 RPS x 10
powerstrokes per rev = 120 PowerStrokes/sec. Fuel burn at 1,000 gph
is less that 1/3 gal/sec so the amount of fuel per power stroke is
actually not all that high, maybe about 1/4 ounce per stroke.

Wayne, I found some specs. Scroll down to the FAQ's.

It's pretty interesting.

9- 9cyl. 4- stroke engines at 400 RPM running on Baker's fuel. No
wonder it's rated in tons.

Interesting, thanks.

Note that by using a diesel-electric propulsion system, they have
cleverly eliminated the need for alternators and generators... *

Thank Goodness!!!!

"The Marina can accommodate 40 yachts from 30 ft to 250 ft LOA with a
maximum draft of 16 ft and a maximum beam of 44ft."


Good Lord! I think my 27 ft. Cavalier could have probably fit in the
master closet with room to spare!

in fact just like us but they do have more money and more toys.

At least bigger money and bigger toys.

Some of the folks that hang out there obviously have giga bucks. Since
they could go where ever they wanted, that tells you something.

It really is a great place and the marina is reasonably priced, at
least for boats in our size range.
