Blimey, JF, I make that only about .75l per NMile per engine.
That is excellant economy isn't it?
But another "daft" question.
Why would you not have one 88gal. tank with baffles to stop slopping?
The tank system I'm speaking about on this thread is not my own,
mine has two tanks, very different in shape, but with the same capacity (44 galls) this is quite simply to get them in the boat!
One is under the cockpit floor, it's long, wide and flat (with a sump). The other is under the rear bench seat (accros the boat) this has a square section and is the width of the cockpit.
Given the type of use the boat gets, the tanks are heavily baffled (like me)
With regards to fuel consumption, one must remember that the boat is essentially made for fast passage, during the near 3000 miles that i've covered in it, most longer journeys have been run at 60ish mph, infact an average of 60. This is not the most economical speed, that I reckon is more like 50.
Cruising at 60 it burns 20 galls/hour total (flat out 30 galls/hour = 71 mph) so the sums are simple, if you were to run till empty you could in theory cover around 265 miles from full tanks!
and I reckon probably over 300 at 50mph.
