Background: Commandant Jacques Cousteau, the man popularly associated with the development of the aqualung for skin diving, demonstrated his latest contribution to maritime technology on June 9, off the coast of Marseilles, France. The Cousteau Foundation showed off a 22m fireglass sailboat 'Moulin a vent' (Windmill), a world leader because it has no sail. Instead of a flexible sail hung from the mast, Cousteau's boat has only a mast through which the air is deflected. The mast is 13.50m high and measures 2.25 m front to back and 1.50m across. The surface are of the mast/sail is 30mÃ½. It is angled by motors so as to feed air from the front of the mast, through the inside and then by controlling its flow out, drive the boat. Cousteau estimates that savings on fuel costs are as much as 30 per cent, against using engines. He says that in a 20 knot wind 'Windmill' has reached a speed of 8 knots. The claimed fuel savings are, he says, much better than other similar projects as a modern Japanese ship with sails saves only 8 per cent on fuel.
