A small 6 man yacht or trawler, extra gas on board. What would be an approximate guess on the gas expenses? Just basically looking for some examples of long distance boating trips and how much the cost of gas was, the distance and the type of boat. Oh and I don't need to know what's "wrong with my plan", just give me your example of your boating trip or an estimate of gas (diesel) costs for that distance, or scram and don't answer the question.
