Guess what else doesn't use oil?
Powered by the unforgiving winds of Lake Calhoun, my uncle Jim-the captain of a 21 foot Reynolds catamaran took us out for a 2 hour tour. Compared to a 2 hour outing on a motor boat, we saved about 30 gallons of gas. This is 71% of a barrel of oil and equivalent to 1,098 kWh (about 5 months of our electricity bill). According to this article... http://www.boatingmag.com/skills/calculating-fuel-consumption:
"On average, an in-tune four-stroke gasoline engine will burn about 0.4 to 0.45 pounds of fuel per hour for each unit of horsepower. Likewise, a well-maintained two-stroke outboard burns nearly 0.6 to 0.8 pounds of fuel per hour for each unit of horsepower it produces. These figures apply to carbureted and fuel-injected engines, but not to direct-injected engines such as Mercury's OptiMax and OMC's FICHT models."
This means that a 150 horsepower engine would use about 15 gallons of gas per hour.
In addition, 1 gallon of gas is equal to 19.564 pounds of CO2. This website has some examples of how you can reduce your gas usage on a boat http://www.boatcarbonfootprint.com/.
Or....you could just go sailing instead :)
