Sailed an infusion Mk1 with gybing boards and loved it. Really felt good in flat water. If it gets a bit bumpy they can flop around in the case but not as much as you think. Didn't really understand when they started locking them off. Was just the fashion at the time I think.

Love the gybing boards on the viper. You can feel them click in and the thing takes off upwind. They never really move in the case even in bump so i guess AHPC managed to get it right.
