I have been looking for a trawler to do the loop for less than $100K. I've considered Island Gypsy, President, Grand Banks, Marine Trader and others but have now come across a 1987 36' Hatteras Sedan with twin 375 hp Caterpiller Diesels, in great shape, low hours, that meets my budget. Its not that much different to the President 37 Sundeck I was looking at in terms of power, and I prefer a sedan layout. And from what I have researched, Hatteras has an exceptional reputation for building solid quality yachts. So my question is, can I run this at trawler speeds (7-8 knots), or alternating on one engine to get the fuel economy I'd am looking for without wrecking the engines. 2-4 gallons per hour is what I am looking for. Your advice would be appreciated, as well as any comments you might have on the 36 Hatteras sedan, or Caterpillar* 3208TA engines. Does this make any sense* as a Great Loop boat when fuel economy is important?
