Action please! The EVOLUTION flies at top speeds on just one hull over inland lakes or coastal waters and offers good positioning and stability even in stronger swells and at winds up to force 5 on the Beaufort scale. It is ideal for two sporty sailors but it also packs plenty of fun and space for families with children and luggage. This medium-sized member of the Grabner HAPPY CAT family combines excellent sailing characteristics with speed and fun. This inflatable cat can be stowed away in just 3 bags and is particularly popular with motorhome enthusiasts.
