100W Wind/Water Generator
12Vdc, 24Vdc, 48Vdc

Towed Turbine Generator when sailing
Wind Driven Generator when at anchor

 

Aquair 100 Hybrid Wind & Water Generator

Towed turbine generator for yachts, and optional wind conversion kit

The most effective means of generating electricity to recharge 12v/24v batteries at sea.
* Generates approx. 1 amp per knot (12v) at average cruising speeds.
* Rope transmits power of spinning turbine to on-board generator.
* Gimbal mounting of generator gives fool-proof operation & long-life.
* Simple installation from stern rail - no permanent hardware. Easily rigged.
* Thousands in use worldwide. Hundreds of circumnavigations made.
* Highly suitable for use on long distance blue water cruising yachts. 
* Wind turbine conversion available for use at anchor.

The Aquair pedigree

Proven over thousands of miles of ocean cruising. Reliability is achieved by using a towed turbine on a 100' line directly coupled to the alternator shaft. Totally sealed alternator. Stainless steel gambol ring provides a simple and automatic alignment method.

Built to professional standards for long term endurance and backed by full manufacturers warranty. The Aquair 100 is constructed of marine grade materials for minimal maintenance. Only a spare turbine is recommended to cater for accidental loss. Electrical contact is direct to the battery using a simple on/off control switch.
Advantages of the hybrid system - why water drive and wind drive

An Aquair greatly reduces the frequency of engine running to recharge service batteries. The Aquair 100 generates sufficient power to run an autopilot, maintain navigation equipment or support a fridge. Produces a continuous output up to 7 Amps at 12 volts. Permanent magnet alternator, has no commutator brushes, windings cannot overheat so requires no thermal cutouts.

The Aquair 100 is a towed turbine generator when sailing and a wind driven generator when at anchor. The reason for the choice is that when sailing downwind at 6 knots, the Aquair 100 Water Drive generates approx. 5 amps continuous charge. Contrast this with the fact that to obtain 5 amps of generation from the wind driven version while underway, the wind speed required is typically 30 knots (24 knots plus 6 knots boat speed) and you can see why long distance cruisers prefer water drive for reliable continuous power. And when the boat is at anchor or in harbor just rig the generator in Wind Drive - either on the pole mount kit or using the hoist in rigging kit, and have all the advantages of a wind turbine

Aquair 100 generator technical description

16ft of 2-conductor cable connects the Aquair generator to the battery. This can be terminated direct to the battery, but we suggest wiring through a switch, fuse and ammeter (10 Amp for 12v, 5 Amp for 24v) and also the use of a through deck plug and socket. A second deck socket should be considered for fore-triangle hoisting of the wind version. A cable extension up to 16ft can be made using the same wire. Operating a towed generator with the switch in the open (off) position will not damage the unit but will generate a high open-circuit voltage, which must be treated with due care. The Aquair 100 generator features built-in rectifiers which convert AC to DC and block reverse current flow, while the permanent magnet alternator can even charge a totally flat battery. The special two bladed turbine is streamed behind on a high strength line which transmits the rotation of the turbine to the generator (in much the same way as a trailing log does). A safety break-link connects the rope directly to the alternator shaft which protects the generator and fixing point in the event of a fouled turbine. A combination of line length and the weight of the stainless steel turbine shaft, prevent the turbine skipping in normal sea states while limiting drag to produce only minimal speed loss (between 1/3 and 1/2 of a knot for yachts of 30ft and over).

Turbine surfacing occurs at 7-8 knots for the standard pitch unit and 12 knots for the coarse pitch. The slower speed of the latter reduces output by over 50% below 7 knots. Less drastic adjustment can be made by increasing the tow line diameter and length or by adding sinker weights to the turbine. Frequent skipping caused when a larger yacht surfs down waves in heavy seas can lead to the turbine tangling with its own rope. A short length of hose over the rope will help prevent this. Shorter tow lines of 65ft are usable on smaller yachts which typically sail at about 6 knots maximum speed. Generally, it is necessary to slow to retrieve the turbine and line, otherwise hauling it in hand over hand is difficult, due to its spinning power. Once on board, the line must be re-streamed without the turbine to unwind the twists and kinks.

DC cable length and voltage drop must be evaluated carefully when laying out system.  Click here for our simple voltage drop calculator.

Maintenance and Recommended Spare Parts

The Ampair 100 is designed so that users can replace those components that wear out over time or that become damaged in accidents. In remote locations or on long sailing voyages accidental damage is always a possibility. We suggest that two spare wind turbine blades be carried. Other spares to consider are: Pivot Seal, Shaft Seal, Set of Brushes and Caps.  Recommended short-term and long-term spare parts are listed below.

Short-Term Spares Long-Term Spares

Q01-SP-11 or Q01-SP-12

Towed Turbine  - standard pitch <7 knots
or coarse pitch >8 knots
Q01-SP-21 Tow Rope - 100ft
Q01-SP-13 Wind Turbine Blades - matched set of 2 Q01-SP-22 Shaft Bearing - set of 2

Mounting options

Aquair Stern Deck Mount

Suitable Stainless Steel fabrication to accommodate the Aquair 100 gimballed generator on yachts without a suitable push-pit e.g. those with canoe sterns, rails separated by less than 12 inches and many multi-hulls

Aquair 100 Hoist in rigging kit & Pole mount kit for wind charger option

There are two Aquair 100 kits to convert the towed turbine generator to wind charger for battery charging at anchor. Conversion consists of a 6-blade wind turbine, direction fin plus top & bottom swivel poles or pole & pole mount assembly. This enables the Aquair 100 to be hoisted in the rigging or stern mounted for use at anchor.
