Quick Answer

Our free boat fuel estimator calculator delivers instant, accurate fuel cost predictions—no sign-up required. Simply input your vessel specs, speed, and trip details to estimate consumption using proven formulas like GPH = (SFC × HP) / FSW, where medium yachts burn 20–80 gallons per hour at $4–$7 per gallon in 2025[1][3]. Plan trips confidently, avoiding shortages or excess spending on extended voyages[1].

Why You Need a Boat Fuel Estimator

Boating trips often face unpredictable fuel costs due to fluctuating marine diesel prices of $4–$7 per gallon in 2025, leading to shortages, overspending, or inefficient routes[1]. Medium-sized yachts (40–80 feet) guzzle 20–80 gallons per hour, while superyachts hit 500 gallons per hour, and sailboats use 1–5 gallons under power—amplifying expenses for long cruises[1]. Globally, marine fuel hit 300 million tonnes annually (6.1% of world oil demand in 2012), with the optimization market surging from $12.01 billion in 2024 to $13.75 billion in 2025 at a 14.5% CAGR[4][9].

Recreational owners, yacht captains, marina operators, and eco-focused fleets under IMO regulations (e.g., sulfur caps, decarbonization goals) rely on these tools for precise planning, emissions tracking, and 20–50% fuel savings via optimal speeds[1][2][3].

How It Works

Enter your boat's horsepower (HP), engine type (gas/diesel), speed, hours, and local fuel prices into our intuitive calculator[3][8]. It applies the core formula GPH = (0.50 lb/HP × HP) / 6.1 lb/gal for gas or 0.40 lb/HP for diesel, factoring in cruising vs. peak modes, then multiplies by trip time and price for total costs[2][3]. AI enhancements account for weather, trim, and routes for real-time accuracy—no downloads needed[1][3].

Tips for Best Results

  • Use precise specs: Displacement hulls at 8–12 knots or planing at 20–25 knots for peak efficiency[1].
  • Track variables like RPM, load, weather, and auxiliaries (e.g., generators) via logbooks or flow meters[2][3].
  • Compare outputs to budgets—aim for slower speeds yielding 20–50% savings; cross-check with real trips[1][3].
  • Generate reports for IMO compliance, future planning, or biofuels integration to cut emissions[2][3].
