What he said. Fuel costs in a trawler will be the least of your concerns. They are a bit more significant in my current boat which burns three times as many gallons per hour as my twin engine trawler did (but goes twice as fast). However, my fuel costs are still insignificant to the overall budget. And, hey, welcome aboard.
