John, It is true gas is more readily available than diesel. However, trawlers do not have diesel "trucked in" because it is not available, but rather because they want to save money. In many places where diesel is available for $1.50/gal you can get it delivered by truck for less than $1/gallon. If you are in need of 3 to 4 hundred gallons, you can save nearly two hundred dollars. There are problems with having fuel trucked in. In some locations it is illegal. You also have to find a place where you can tie up and get a truck close enough. Marinas usually frown on it since they make money pumping fuel. All in all we have purchased "trucked" diesel fuel twice in 9 years. One experience was good, the other wasn't. In one case we saved lots of money, in the other we took on a load of "bad" fuel and spend hundreds of dollars in fuel additives and filters to burn up the poor fuel we got. That was 1995 and we never bought fuel from a truck again. When you get a bad load from a truck, you can't really go back and complain like you could at a marina. The marina is not going anywhere. The truck driver just drives off never to be seen again. What he doesn't sell to you he pumps into someone's home to burn for heat. Diesel fuel is readily available all along the Great Circle Route for vessels with a range of over 300 miles. I have never met anyone on a diesel powered trawler without that kind of range. Most can go over 1000 miles without fueling up. By the way. Your fuel estimate is very realistic and you will probably enjoy the Great Circle Route because you are planning properly. Best of luck and do not hesitate to ask any questions you may have. Bob Skipper Bob Publications Web page: Http://SkipperBob.home.att.net
