Yeah, but the sol cat is a great deal. Believe me, if the two were even if a close price range, I would definitely go with the Hobie- and i still might
The Sol Cat was a great boat in its day, and you may get lucky with many of the parts that are generic, but will have a hard time with those that are not, rudder casting, rudders, mast casting, beams, etc......
I see your in Northern CA. There is a big very active Hobie fleet up there and a great deal of support close by with Surf City Catamarans.
