Perfectly matched system integration rather than an assortment of components

The most powerful electric saildrives come from Torqeedo series production. The Deep Blue 25 SD propels sail yachts of up to 40 feet in length to speeds of up to almost ten knots (18 km/h), or smaller boats even faster when planing. This makes cruising with large sail yachts completely emission-free with virtually no noise or vibration. The Deep Blue 50 SD offers twice the performance. The Deep Blue sail drive is part of a completely integrated comprehensive system that was developed using industrial engineering methods, comprises high-tech components and which is manufactured in series production.

Light and quiet

With an overall weight of about 125 kg for motor, sail drive and electronics, the Deep Blue 25 SD (50 SD ≈ 180 kg) weighs less than a conventional saildrive with combustion engine. This benefits weight distribution on board, as the low net weight of the Torqeedo Deep Blue Saildrive makes a sailboat noticeably lighter at the stern than a similar configuration with a petrol or diesel engine when the motor is installed toward the rear.
The weight of the lithium battery can also be used to advantage in the design of the boat. The fact that the battery package can be arranged variably when the Torqeedo Deep Blue Saildrive is installed allows the weight of the drive system to be distributed around the centre of the vessel. This is the arrangement favoured by boat builders and boatyards.

Travelling silently even when under motor power

No sailor likes the sound of an engine when travelling in calm conditions or when casting off or landing under engine power. In contrast to conventional petrol- or diesel-powered sail drive engines, the Deep Blue 25 SD & 50 SD operate quietly, creating extremely low noise emissions. The electric sail drive operates almost in silence owing to the nature of the system. Due to the system, the electric saildrives operate almost silently.

Number 1 in power delivery

The Deep Blue Saildrive produces the equivalent of up to 80 hp of power, ideal for use in displacement boats and large sailing yachts.

Complete integration

The Saildrive drives are part ofTorqeedo’s Deep Blue series of high-performance motors. The high-tech components of the fully integrated overall system are carefully selected to match each other and are perfectly adapted for use on water. They offer professional safety features, compliance with international standards at system level and extreme ease of operation. The motors can also be used to generate electricity. The seamless integration of the saildrives into Torqeedo’s hybrid system offers the option of recovering energy while under sail through hydro power generation using the electric drive.

Low incidental costs

There are no incidental costs for petrol or diesel or for regular maintenance incurred by a combustion engine.
Since the lithium batteries are manufactured to the same high standards of quality as in the automotive industry, Torqeedo offers a warranty of nine years on battery capacity, promising a residual capacity of 80 % after nine years of daily use.
