Plus, if you get one of those official yellow 5 gallon plastic jerry cans
and strap it to your stern rails it looks veeeeeeeeeery cool.

Scotty's boat has an LWL of 25 so 5 knots means an S/L of 1.0.

Pushing a boat
at S/L of 1.0 needs one HP per 1200 pounds, which for 7500 pounds is

6.25.
Assuming 0.055 gal/hp/hour means about .35 gal/hour or about 35

hours run time.
At 5 knots, that should give him a range of 175 miles.

If you look at the specs of the 2GM20, these numbers are close to

realistic,
though there are variables not considered, such has the propeller

setup, and the
cleanliness of the hull.

So in theory, there should be no problem. If his only concern is no

wind, then
he should be able to come close to these idealized numbers, or even

do better by
slowing down some. However, if headwinds are a problem,or if the is

absolutely
no alternative source of fuel, he might want to carry a reserve,

especially
since he can gain 50% capacity with a low cost jug lashed on deck.

I have done 75 miles using about 7 European gallons on

Doesn't help any, Donut. Where am I going to find Euro

gallons over
here?

You must have missed the bit where I said that US gallons were

about 90%
of
UK gallons.

Your 12 gallons are about 10.8 of my gallons. Therefore, my

opinion is
that
12 gallons will be fine as long as you don't try to motor into

strong
head
winds.

I didn't mean to embarrass you .. honestly ... I wasn't aware

that you
were
mathematically challenged!!

You're not much better, Donal.

Correct ... but I deliver my insults with more panache!

12 US gallons are under 10 Imperial Gallons.

Again, You are absolutely correct. I hadn't realised that US

gallons were
so small.



Now that we have the confessions out of the way, do you think that

Scotty
should attempt his trip without spare fuel?



Regards


Donal
