Daggerboard rudders which kick up are fine so long as everything is
braced all the way up. The board kicking out the back of the case is
an awful solution as it wrecks the case on the way. The new boats
have beam mounted rudders with either the Blind Date solution or a
tube which rotates around the beam.

Rob
