Sailboats get better gas mileage than you think...+

Okay, I'm teaching sailing off a Beneteau First 7.5. Lots of fun, and pretty responsive for the students. I tend to use the motor (Yamaha 4-hp single cylinder, 4-stroke) as little as possible, but in the light summer air, sometimes we have to. So it seems from experience that the .3 gallon integral tank lasts almost an hour at 5 knots. So that's about 15 miles per gallon, or a little more.

Pretty good for a sailboat with a few students on board. How do we do this? Some cars don't do this well, and they have a lot less resistance going over the road than we do going through the water...

I typically measure this in GPH, but in MPG terms, it's not too bad.

Strange, but true??

This is precisely correct! I recently drove my 37' Hunter from Muskegon to Ludington (winds didn't cooperate and we needed to make time to get there fast enough to see friends who we're leaving) and over the course of the trip we averaged about 10-12 miles per gallon as i can calculate, running roughly 6.8 - 7.2 knots at about 1300rpm on a 27-hp Yanmar. I always love bringing that fact up to the powerboaters at the dock. At least when i have to motor I don't get .8MPG, and i get an extra aft cabin out of that engine space =). Of course i didn't buy it for the engine, and "unlimited" MPG is truly the best!

Of course if you drove a car at 5 knots, you'd get ridiculously good mileage, too.

Nolatom, perhaps inadvertently, reveals an important point. Waterborne transportation of commercial goods is the cheapest form of transportation there is available. From ferry boats to freighters, nothing moves large quantities of people, possesions, and cargo as inexpensively. Not necessarily fast, but cheap.

And, as Tom notes, when you put a number of people on a sailboat in pursuit of a destination the costs can begin to approach negligible. As I have had recent cause to mention, "speed costs money" how fast do you want to get there? And btw, are there really any sailors out there who are really not Dutch at heart? (g)

I believe a scooter would get similar gas mileage. But I like to get where I am going so I can spend more time sailing.

That is why a Trimaran sounds cheaper on gas! It goes when there is no wind or I should say a little wind.... If its classy then you can use the motor!

Actually, you'd get really lousy mileage, since you're running the engine down in a very inefficient part of its operating range. If you think about how much gasoline an engine burns idling for an hour and figure that you're using a bit more than that to go all of six miles... your mileage is going to really suck.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
