One interesting design I've seen is the kickup system for the
Dragonfly 35.
The line holding the centerboard in place is routed up on deck and
then through a jam cleat to hold it in place. The cleat itself is then
built into a hinged box, with the hinge on the tensioned side, so the
cleat can flip up and let out the line. The cleat is then held in its
normal position by a ball bearing on a spring (push the cleat down, it
pops through the bearing, and the bearing then holds it in place).
When enough force is put on the cleat, it pulls upward past the ball
bearing, which then allows the cleat to fully pop up on the hinge,
which then releases the line.
I'm not sure how I'd do this on a rudder that turns more than 90
degrees, but it's still a neat way to tackle the problem.

The fuse system worked very well but make sure you have some spare fuses on hand or you may be tempted to replace it with something else that doesn't give.
