The Sail-Gen water generator produces electricity as you sail and is easily capable of matching or exceeding your yacht's power consumption. The Sail-Gen shares the same operating principal as the DuoGen's water mode, which is well proven over hundreds of thousands of sea miles.

The Sail-Gen has the same geometry as the DuoGen and also utilizes the same alternator, water impeller and drive train. The Sail-Gen comprises a rigid welded aluminum frame with carbon fiber drive shaft and cast alloy impeller. It is compact in size and both reliable and efficient in operation. At typical passage speeds (5-6kts.) the Sail-Gen is capable of matching power consumption, freeing the owner from
engine runs to charge batteries.
Direct-drive 1:1 ration impeller to alternator - no gearbox or added friction.
The alternator is not submerged and is, therefore less liable to failure through water ingress.
The slow speed, permanent magnet alternator is robust, highly efficient and well proven. Featuring stainless steel shaft and bearings, powerful ferrite magnets and heavy copper windings, this unit is capable of sustained outputs in excess of 500 watts.
A standard 280mm diameter impeller is available for yachts with passage speeds up to 9kts. A high-speed 240mm diameter impeller is recommended for boats capable of speeds up to 15kts.
Using a regulator with a diversion load "dump" is standard installation procedure and should be rated at a minimum of 40 amps at 12V.
The Sail-Gen weighs 16.7 kg (36.8 lbs.) excluding mounting.

Dive Plane:
The Sail-Gen's running depth is controlled by a "hydro foil" or "dive plane". This means that the water impeller flies through the wave action at a constant depth and is not directly affected by the pitching movement of the yacht, as occurs with the "outboard leg" type generator. This prevents the water impeller from surfacing in all but the most extreme conditions. The running depth is simple to adjust and optimize.
Recovery of the towed generator is easy regardless of boat speed.
An impact wire can be fitted to move the dive plane in the event of a collision with floating debris.

Brackets and Installation:
The Sail-Gen is supplied complete with an alternator yoke and C-bracket. Together, these form the gimbaled mount for the Sail-Gen and allow the unit to pivot both vertically and horizontally when deployed. This bracket should be attached to the yacht within 500mm of the center line, and to get the C-bracket to rest somewhere between 400mm (16") to 540mm (21") above the static water line. The C-bracket can be through-bolted to the transom, but there are also many other options for mounting available. Ask for more information.

In its "parked" position when not in use, the Sail-Gen is held in a vertical position by a frame clip integral to the mount hardware.
Very easy retrieval and recovery of water generator at any boat speed.

Drag and Speed Loss:
Drag and resulting speed loss from water generators are often over-stated. Drag from the Sail-Gen is less than 15kg at 6kts and typical boat speed losses at that speed are in the order of a tenth of a knot or less. Unlike tow-rope type water generation systems, the Sail-Gen is truly practical in use and can be deployed and recovered in seconds and with minimal effort. As the Sail-Gen operates in a controlled way with the impeller close to the transom, drag is minimized and it is possible to trawl fishing lines when on passage with minimal risk of a tangle.
