HF (Hybrid Foil) Blade rest screws to your back deck - to stop the rudder blade banging into the deck when retracting.

Hook holds the rudder down when not in use.

This blade rest is useful for a range of flip-over rudders. In the Smart Track range it is useful for the Hybrid Foil system but not for the standard rudders (Original, Compact, Race, Flow, Ski) as these rudders sit vertical when not deployed.
