This is the gennaker we have ordered for the SaltyPaws. Catamarans are normally faster than monohulls, but this is not so in light winds. Due to the higher wetted surface area of a catamaran compared to the mono hull, there is more friction which leads to a slower boat speed. The solution... The Gennaker. Due to the wide hull of the catamaran no pole is needed to fly this sail, and a massive 113m² is added. We have opted for the All round Quantum A3 Assymetrical cruising spinnaker.

The polar chart shows that the A3 genaker can be used 90 degrees to the wind in light winds (<8 knots) and between 120-170 degrees in fresh winds (21 knots +). Personally I don't intend to use the gennaker in winds >20 knots, as by that time we will be making some good progress with the normal sails. We have added a launch funnel, to make setting and removal of the sail a breeze with a crew of 2 humans, and 2 cats.
