Hi Folks. Please don’t pile on the what is a trawler discussion, but I have a 2002 Sabre 34 running two diesel yanmars at 310 hp each and I am trying figure out if we can extend its range to get to the Bahamas from Florida by going slower. It has an odd consumption graph where the faster you go the more miles per gallon with the best going 17 to 23 knots with one gallon per knot at 3000 rpm with a range of 225 nm. Anything less drops the mileage to .7 nm per gallon. The consumption chart from Sabre stops at seven knots at 1400 rpm at 160 nm range. I have researched and my waterline is 30.25 feet so my hull speed is about 7.2 knots. If I am below hull speed, do you think I can extend my range or is this just the downside of a fast trawler?
