We recently had a report from John and Jane Linscott who ran their beautiful Claret colored Back Cove 37 Maine Event, from Ft Myers, Florida up to Portland, Maine. The distance was 1946 miles and the fuel consumption was an astoundingly low 1255 US gallons. They averaged 20 knots of boat speed.
Back Coves are very reasonable on fuel and with fuel prices where they are today, many boaters are considering a change to a single diesel engine vessel like the Back Cove 37. When we calculate fuel consumption for this boat at those rates of speed, we come up with a 1.3 mpg burn rate for the Cummins 600 hp QSC 8.3 engine. However, fuel rate on these engines is calculated by the internal computer and not by a flow meter. John and Jane's actual fuel rate was 1.55mpg so they burned 242 gallons less that we would have predicted for this voyage.
Do the math and you'll see what they saved. I loooked up fuel consumption rates for a boat of the same size built by another US manufacturer with twin diesel inboards. Their boat burns 30 GPH where as the Back Cove burned 13 GPH ! That's half the fuel and every bit as much fun!
