There is no difference to the height or speed you can sail an Infusion, tiger or capricorn with a shy kite. The method used on each boat differs but the outcome is the same.
So what is the secret for the wing mast boats then? There are some Infusion sailors who would like to know. I think one team tried a few settings on the last day of the Tybee that resulted in a folded mast.
