|Speed in km/h*||Range in km*||Running time in hours|
* 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.
