Aquair Wind & Water Generators
The Aquair 100 Wind and Water is a dual-purpose generator. At anchor or on a mooring the Aquair wind generator hangs from a halyard on the foredeck, collecting energy from the wind, generating 50 to 100 amp hours per day.
Once underway, the wind blades are removed and the generator is lashed to the stern rail with a gimbal ring. The water turbine is then payed out and towed on a 100' warp, where it makes power from the motion of the boat through the water. The water generator is especially effective when the boat is running before the wind for long periods of time and the apparent wind is low. (The electrical specifications are the same as for the Ampair 100).

Power from Wind & Water

On most boats, the engine alternator is the primary source of power. Wind- or water-driven alternators are an excellent supplementary power source. The best systems are based on the Aquair (combination wind and water turbine). Complete kits, teamed with appropriate regulators.
Aquair wind- and water-driven alternators are state-of-the-art products designed to supply the most power for the least trouble and expense. They are durable, lightweight, simple to install, and completely quiet and free of vibration. Best of all, they quietly go about their business of charging your batteries 24 hours a day, whenever there's a breeze--at sea or at anchor.
Your choice of wind and water generators should be determined by the way you plan to cruise and your itinerary. Unless you plan to be at sea for long periods, you'll probably be happier with a permanently-mounted, wind-driven Ampair. If you're planning long passages, you may prefer the Aquair convertible wind/water generator. Generally speaking, water generators produce more amps than wind generators, particularly when you're running before the wind.
The graphs appearing for the Aquair, below show the rated power output at various wind and water speeds.
