Fuel Economy

After more than 2,000 km traveled in Escapade I’ve tallied fuel consumption. I’m happy with the results. Regular readers will recognize that this is important to me. Not just for cost reasons, but also to try to do more with less fossil fuel.

For reference, I tracked fuel consumption carefully on Mazurka, and for my loop trip my overall economy was 4.4 USMPG. Backing out generator use takes it to about 4.7 mpg.

I could easily have burned twice as much fuel or more. At a fast cruise in Mazurka mpg was 2 mpg or less. But I was committed to economy, and had a boat that performed pretty well across a range of speeds. Mostly I went slow, with an average speed of about 6.5 knots.

Escapade is a much larger boat than Muzurka. It’s twice the weight. But it has a smaller more modern motor than Mazurka, and more importantly has a longer waterline. It’s all about hull speed.

Here are some gatherings:

USMPG: 4.9

Average speed: 7.0 knots

That’s great. I fully expect to get 5+ mpg in my extended travels. Better than my last boat.

I won’t boast about how much fuel I burned heating the boat last winter. But I kind of wanted to try the brute force approach. If I do a repeat I’ll do more winterizing and insulating…
