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. John Cairns "Scott Vernon" wrote in message ... I think I will. Just for peace of mind. Scotty "Jeff Morris" wrote in message ... 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.

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 -- |
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. Regards Donal -- Regards Donal -- |

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. Scotty |
Scotty,
That is a very, very good point. I have a 20 gal tank and it s a fitted tank so the bottom 1/4 tanks drains a lot faster than the upper 3/4 due to the curve of the hull. Ole Thom |

So, my little mathematical error is of no consequence???? We all agree that a bit of spare fuel would be useful. Your opinion is of little consequence in any case. I was just pointing out your faulty conversion in case some newbie didn't know your track record. To be honest, I had been taught that an Imperial Gallon was exactly 5 US quarts, but its actually a bit smaller. I was surprised to learn that US and British pints and liquid ounces are not the same, either. |
