Make Gas Last

With summertime gas prices skyrocketing, here are BoatU.S.'s top ten tips for getting the most from a tank of gas.

1. Leave the extra ‘junk’ home: Don’t load the boat up with weight you don’t need. Do a little spring cleaning—unused equipment that has been collecting mildew in the bottom of lockers for years should be taken home.

2. Water weight: At 8.33 pounds per gallon, why keep the water in the tank topped off if you’re only going out for the afternoon?

3. Tune her up: An engine tune-up is an excellent investment and should easily pay for itself over the summer.

4. Tune your prop: If your boat goes 30 mph with a like-new prop and only 27 mph with a prop that’s dinged and out of pitch, that’s a 10% loss in fuel economy, or, you’re wasting one out of every ten gallons you put in your tank.

5. Paint the boat’s bottom: When boating in salt or brackish waters a fouled bottom is like a dull knife. It takes a lot more fuel to push your boat through the water.

6. Keep the boat in trim: Using trim tabs or distributing weight evenly will help move your boat through the water with less effort – and less fuel.

7. Go with the flow: Consult tide tables and try to travel with the tide whenever possible.

8. Install a fuel flow meter: A fuel flow meter is like a heart monitor; when consumption starts to rise, it’s an early warning that something is amiss. A fuel flow meter also allows you to select a comfortable cruising speed that optimizes the amount of fuel being consumed. If you don’t want to spring for a fuel flow meter (about $300), you can calculate your fuel mileage by dividing distance traveled by gallons at fill-up. Using your logbook, you can then approximate fuel flow using average speeds and time underway.

9. For sailboats only: While their engines are miserly, a sailboat with a fouled bottom, prop, or poorly maintained engine can have marked effect on its fuel economy.

10. Get a discount: Many of the 870 BoatU.S. Cooperating Marinas around the country offer up to 10 cents off a gallon of gas. To get the discount all you have to do is to show your BoatU.S. membership card.
