My parents are wanting a boat to sail together. They know how to sail, they weigh about 140kgs all up and want something that they could race in the future. Ideally the boat would have three sails and no trapeze. A swing centreboard would be nice and the class must be readily available in Australia. Even though it doesn't meet some of the criteria, my parents are currently considering a Taser. However, any other suggestions would be appreciated.
