* Dependent on factors such as type of boat, load, propeller and ambient conditions. Figures for speed and range are indicative only and are not a guarantee of performance.
Example: Fishing kayak Hobie Mirage Revolution (4.1 m / 26.3 kg)

Information on range and speed

For a displacement boat making way through the water, the required propulsive power increases in proportion to the cube of the speed. This means that if you want to double your speed, you need eight times as much power.

And vice-versa, a small reduction in speed is enough to increase the achievable range substantially.

The Torqeedo Ultralight's on-board computer calculates the remaining range constantly, by linking the motor's consumption data with the charging level of the batteries, and the speed over the ground from the GPS. This allows you to read the remaining range in real time from the motor display or the smartphone app TorqTrac.

* Torqeedo static thrust measurement is based on internationally accepted ISO standards. Static thrust figures for conventional trolling motors are typically measured differently, which results in higher values. To compare Torqeedo static thrust data with conventional trolling motors, add approximately 50% to the Torqeedo static thrust values.
