Deep Blue 25 Saildrive V 1.4

Saildrive drive system

The most powerful electric saildrive from serial production is a Torqeedo. The Deep Blue SD can propel displacement vessels weighing up to 50 tons as well as large yachts at speeds of up to 18 km/h. This makes cruising with large yachts completely emission-free with virtually no noise or vibration.
The shaft-free design allows installation at almost any point and makes maintenance of the Deep Blue SD very convenient. Seamless integration with the Deep Blue Hybrid system offers the option of energy recovery while sailing.

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 Deep Blue’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.
