List Friends,
Our new to us 35' Cat (designer unknown) appears to have both rudders toed in about half a degree from parallel. Is this a normal thing with cats or a builder's mistake? My experience is with trimarans and I would think they should be parallel with the centerline of the hulls. The rudders are a tapered NACA 0012 foil with the shaft at 25% of the chord. I'm reattaching the tiller crossbar at the ends of the tillers, and it is 1 1/2" shorter (center of tiller hole to hole) than the rudder shafts are (14' center to center) The tillers are 58" long.
Thanks for any advise!, John Matthiesen, Sugaree Too
