I would love to take a ride on that wildcat!!!
I do not have much experience with different catamaran rudder systems as I have a 1976 Tornado (since 1986) and a 1988 H21SE (new this spring). I also have not sailed with other cats to know all the differenct rudder systems. I do know that my old wooden Tornado rudder is hands down much better than the Hobie system. These are my recreational rudders that seem similar to the new Wildcat and am posting pictures for discussion. My racing foils are fixed and do not retract.
Here is the starboard rudder with blade down.
Here is the starboard with blade up. Port restored rudder in background.
Here are the control lines. The right one pulls the rudder up and uses the jam cleat to hold in that position. The left line is used to hold the rudder in the down locked position. There is bungie spliced into the line to allow some relief from hitting shallow water.
