Dear Tim,

Very difficult question to answer as it depends very much on the cost of
diesel fuel and how automated you make the rig.............

Hi there Malcolm: You might reconsider the performance and cost benefits of sail assisted power cats using a kite from Dave Culp at Kiteship. <http://www.kiteship.com/outleader.php> To quote from Dave' web page: "KiteShip offers the world's first and only performance-based sail guarantee.

It is correct to say that it is mainly for pursuing long distances. We ship our Aventure Power Boats world wide and it is now costing a lot of money and damage in many cases. Therefore we have made a few modifications to our rudders, fitted feathering props, a Sparecraft mast, 4 winches, 2 asymetrical spinnakers and 1x 70 sq meter experimental kite. The total price is $32.500, ($8.000 less than the shipping.) The next time round it will cost only $3.000, the amount it cost me to to ship the mast and sails back to the shipyard for the next boat. The interesting aspect of my findings is that the boat can go very quickly under an asymetrical spinnaker only, set from 500 off the the wind through to 1400 therefore saving good money, and as we all know an asymetrical spinnakers is not a train smash to fly, only a good autopilot and a lot of fun. Therefore, stepping a simple mast, 3 winches, an asymetrical spinnaker can really be a great advantage in the correct conditions, and not a pain. >>> For more information, go http://www.aventure-catamaran.com/ --Georgs
