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. |
are you trying to be obtuse?

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 -- |
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 think I will. Just for peace of mind.
