      Don't rely on me here, but I doubt if a fair bottom will get you near
      30mph. Each successive unit of speed comes dearer than the last; a
      wild guess says your gain will be pretty small (a 50% gain is

      Is the performance near your expectations, or did you expect 30mph on
      Also, how does she handle at manuevering speeds?

      (Is that the Kerr-cLellan channel you speak of?)
