Yachting Monthly Group Gear Test

This model, from Southwest Windpower, USA, supercedes the AirX but spins slower so it’s quieter than its predecessor. Sales of over 100,000 are claimed for both models, in 12v, 24v and 48v versions. The unit has a one-piece cast aluminium fin and casing. The built-in speed and output regulators cut in above 25 knots. It weighs about half as much as its nearest rivals. Mounting is a 50mm (2in) clamp socket. Performance is high, at 89Ah.
