A control arrangement 1 for a kite 6 is attached to a boat 2. The control arrangement automatically tracks the movement of the kite as the kite moves relative to the boat without any external control or energy input. The control arrangement ensures that the kite flies so that the line of action 15 of the kite always extends through the centre of lateral resistance 14 of the boat. This enables the kite to pull the boat without applying any heeling moment to the boat. The control arrangement could be used with a land based vehicle and the kite could be replaced with a collapsible wing. |
