The foil is designed to swing aft and up out of the water if it hits a submerged object, or if the Raptor is inadvertently run up on the beach with the foil down. The rudder also kicks up if it hits something. Only the dagger board lacks this kick-up feature. The dagger board is positioned between the helmsman’s feet and is easily retracted. The Raptor will sail without the dagger board, but it will make leeway when beating or on a reach with the board up.
