For what kind of boat ?

The Torqeedo Ultralight is designed to propel light boats

A major boost for a dinghy, catamaran or a small trimaran .

Fully waterproof, it represents a major element of safety when the wind drops. We can not imagine that this little motor will help to navigate or sail in light airs, the impulse of the Torqeedo Ultralight is enough to go close to the wind while the vessel not equipped seek the wind and drift.


Kayak Fishing: whether to fish in fresh water or go down a long winding river in a beautiful sunny afternoon, the engine option increase the pleasure of kayaker.

* Torqeedo static thrust measurement is based on globally valid ISO standards. Static thrust figures for conventional trolling motors are measured digressively, which results in higher values. In order to compare Torqeedo static thrust data with conventional trolling motors, add approximately 50% to the Torqeedo static thrust values.
