Save fuel
🚗 Drive smoother, not slower. Aggressive acceleration can increase fuel use by 20–40%. Ease onto the accelerator, coast to slow down, keep your speed steady.

🔧 Check your tyre pressure. Two minutes at any petrol station, costs nothing. Under-inflated tyres can cost you up to 3% more fuel.

🗺️ Combine your trips. A cold engine uses significantly more fuel for the first few km. Three separate errands = three cold starts. Do them all in one go.
Boat fuel costs
Your boat fuel impact
Estimates based on your inputs at consistent cruise speed. Actual consumption varies with hull type, load, sea conditions, and throttle use. For the most accurate results, enter your actual L/hr from your engine's fuel flow gauge.
The breakdown
Save fuel on the water
🚤 Trim your engine properly. Running bow-high or bow-low wastes fuel. Find the sweet spot where the hull runs cleanest - usually 2-5 degrees bow up.

Slow down a little. Dropping from WOT to 75% throttle can cut fuel consumption nearly in half. A few less knots, a lot less cost.

🔧 Clean your hull. Fouling on the hull and prop creates drag. A clean bottom can save 10-15% on fuel over a season.

🌊 Work with the tides. Running against a strong current burns significantly more fuel. Time your trips around tidal flows and you'll use less fuel getting where you're going and back.
