Proposal for catamaran rudders

Power cats are different in so much as propeller wash has a tendancy to push a rudder in a direction depending on rotation of the propeller.

I have swopped props to find no difference in handling at all. I have altered toe in and toe out to find that only large changes in either toe in or toe out did any thing to a pre determined set speed to certain RPM.

I also changed geometry of the steering arms to acheive an Akerman principle to the rudders. This change was not as acute as that of a car.

Going only by feel I have to say that there was no noticable difference, it still remains on the boat. Its hard to say but it certainly did'nt make it worse.
