Example of long range fuel efficient vessel built in alloy.
When I first saw it I thought it was a Dashew.

If you are happy to cruise at around 7 knots, an ideal speed to drag some lures on the way to Fiji, the range extends to around 7000 nm @ 0.53 lpnm. At 8.1 knots the fuel rate increases marginally to 0.67 lpnm.

Economy Plus, powered by a 90hp, four cylinder Beta diesel. But donít be fooled, this little engine provides every bit of power the LRC 58 needs.

Very impressive fuel use numbers. 6mpg at 15 mph is really good for that size boat or any boat that has significant accommodations.

Efficiency is a much bantered about term. Real efficiency has to include all costs of ownership and not just fuel use. Design, first cost to build, maintenance, dockage, insurance, etc., etc. Of all similar offerings I've seen though, this is most impressive. So far, no super high efficiency designs have been able to gain any significant traction in the marketplace. Some are even miserable failures in efficiency of total cost.

Nice boat! I wonder if it would use much less fuel at slower speeds with a much smaller engine?

No doubt it would as would most all other boats. The main objection might be that this boat was designed for a particular set of performance characteristics and much expense in design, building and usefulness would be wasted for no reasonable return on investment.

I was just wondering as my last boat weighed 4 times that and used considerably less fuel at 7 knots. A 43' 20000lbs sailing cat (in my picture). That's when using one 24 hp engine with no headwind. So at that speed it seems very inefficient. But of course we only had a 10k top speed not 25K! Most likely at the higher speeds this boat is designed to be operated it is efficient, but I have nothing to compare that to.
