The question about "How to work the Kick-up Rudder" reminded me of something
I had once seen but can't remember where, or on what boat. Maybe someone
out there will be able to fill in the details.
As I remember, the owner had substituted bungee for all, or part of the
downhaul line so if the rudder hit anything it could pop up (at least part
of the way). The bungee would eventually pull the rudder back down. Only
problem I see with this is trying to find the balance between too weak, and
too strong a bungee. Might be worth looking into.
