There's a Farrier trimaran with pull-up rudders in a cassette. Normally you pull them straight up manually, but if you hit something the whole cassette kicks up, saving the rudders. That sounds like the ideal set-up to me! Too bad it won't work for daggerboards! Could be nice on the F14, but maybe it would put too much weight on the transom? (End quote)

There is a 14’ cat (paper tiger) here that has/had such a “kick up” cassette rudder stock system, and we have looked at that system but then decided to keep it as simple as possible. We have had no problems so far with this cassette system even without any kick up ability.
