Let me rephrase the question, to find out how many miles is involved in
this trip:

*In the boating course, how did they instruct you to estimate how much
fuel you would burn?*

re 'Boating Course' Student's Notes 8th edition 1999
Section 11.3 The Fuel Supply

The fuel supply should be checked to ensure that there is enough for the
journey, or that fuel can be obtained en route. Running out of fuel is
the single most frequent emergency that boaters experience. Every hour, a
marine engine can be expected to use 0.6 liters of fuel for each kW. In
practical terms, a 75 kW gasoline outboard motor on a 6m cruising boat
will give about 1 kilometer per litre of fuel. larger boats and larger
engines use more; diesel engines use less, but all boats use more fuel
when travelling against a head wind and adverse current. If possible, the
up-wind and up-current leg of a journey should be completed first, as it
is then easier to return. A good maxim for fuelling is one-third out,
one-third back, and one-third in reserve.

note: Not sure if this section has been updated since.



Don, I'm trying to find out how many miles the trip involves, not how much
gas to take. You're sounding like my ex wife. I'd ask her if she wanted to
go and pick out paint for the living room and she'd tell me what time it
was.


Boy... you are argumentative...
Wasn't your second question...*"In the boating course, how did they instruct
you to estimate how much
fuel you would burn?"*
