Range Calculator
How Far Can You Electric Boat?
Estimate your electric boat's range based on battery capacity, motor power, and cruising speed.
How It Works
Powered by Real-World Data
Our range calculator is built on actual performance data collected by our technicians on the water. For each boat, we record throttle position, RPM, power draw, and speed at multiple points — then use cubic spline interpolation to provide smooth, accurate results at any throttle setting.
Use the map to plan a route with waypoints and see if your boat can make the trip at your selected throttle. The range circle updates in real time as you adjust. Data is updated as we test more boats — check back regularly for new models.
Disclaimer: Range figures shown are based on real-world test results and are provided for planning purposes only — they are not guarantees. Actual range will vary based on water and weather conditions, payload, battery age and state of health, driving style, temperature, and other factors. Always plan conservatively and carry an appropriate safety margin.

Frequently Asked Questions
Our service technician takes each boat out on the water and records throttle position, RPM, power consumption, and speed at multiple settings. This real-world data is far more accurate than manufacturer estimates or theoretical calculations.
Set a starting location on the map, then add waypoints to plan your route. The tool calculates the distance between each waypoint and subtracts it from your available range. A blue line shows reachable segments; a red line means you won't make it at the current throttle setting. Adjust the throttle to find a speed that works.
Speed has a dramatic effect on range. At low displacement speeds (4-6 knots), most electric boats can cruise for many hours. Once you get on plane (typically above 15 knots), power consumption increases significantly and range drops. Finding the sweet spot between speed and range is key for trip planning.
It's a mathematical technique that creates a smooth curve through measured data points. Instead of jumping between recorded throttle settings, the calculator provides smooth, accurate estimates at any throttle percentage — giving you a natural performance curve just like the real boat.
At the national average of about $0.12 per kWh, a 30 kWh battery costs roughly $3.60 to charge from empty. Compare that to a gas boat burning 5-10 gallons per outing at $4-5/gallon. Electric charging costs are typically 90% lower than equivalent gas fuel costs.
Yes! We're continuously testing new boats and adding their performance data. The calculator pulls from a live data source, so new models appear automatically as our team collects the data.
