Well, I have read with great interest all the information regarding economical cruising. For a couple of years I had a 29' Prairie that cruised at 7 knots (average) with a fuel consumption of less than 1 GPH. It was awesome and I loved the little boat which had considerable comfort for it's size. I the realized that I needed a little more space and speed and went on a search for a larger boat with a little more power. When cruising the intracoastal waterways with narrow channels most of the time I encountered too many dangerous situations where I couldn't get out of my own way with the trawler - very sad but the reality! I found a 1985 40' Mainship Nantucket that had been repowered in 1996 with twin 170HP Yanmar diesels. I know there are some originals out there with 200HP Perkins. It is an incredibly fuel efficient boat for it's size and comfort. I average a 13 Knot cruising speed (which puts the boat on plane) with a fuel consumption of about 8 GPH. At trawler speed I know it is considerably better but then one trades speed for economy which is almost a toss-up. it It doesn't get much better than that unless you can be satisfied with something like the Prairie. Good luck with the search! Steve Lattmann "Tranquility"
