I have done 75 miles using about 7 European gallons on flat calm.


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. 12 US gallons are under 10 Imperial Gallons.

Here's the odd thing: Both US and UK Gallons are defined as 8 pints. Except US
Pints are 16 fluid ounces, while the UK pints are 20 fluid ounces. However, in
the US a fluid ounce is 1.8 cubic inches, but in the UK a fluid ounce is 1.73
cubic inches.

Now, if only someone could explain why my 10 cup coffee maker only makes two
mugs of coffee, I'd be happy.

Try cleaning the sediment out of it.





Pathetic Earthlings! No one can save you now!

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

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?

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.

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.

I've got a pair of red, 3 gallon jugs. Gotta keep up the

That sounds like what I said, doesn't it?

I must have been wrong when I thought that you were disagreeing with me.

My only other contribution to this thread was pointing out that you had flawed
conversion for Imperial to US gallons, ironically while you were accusing Scotty
of being "mathematically challenged."

I think everyone is in agreement that 12 gallons, US or Donal sized, should be
enough for a 100 mile trip, but Scotty should still be cautious, since he has
not verified the fuel usage of his boat, or the true size of the tank.

That's an excellant point, Jeff, I have yet to go below the half tank
mark, so I really don't know how far down she'll go.
