We at Aventure Power Catamaran have for quite a few years tried to turn our attention to using kites on our Catamarans. We have keels and bigger rudders to steer under autopilot at slower speeds, but it seems that to fly kites properly you need to trim them all the time to get the maximum out of the them. What we have resorted to is the simple use of a mast, no mainsail or boom and fly bigger and specially cut assymetrical sails which will work perfectly. These sails can be used from a close reach all the way through running and if on a captive winch and roller furling units very easy to use. I have lots of information and VPP program if anyone is interested and we hope to cross the Atlantic in January with one of our production 50 footers. T. Jordaan
