I made up an emergency tiller some years ago, it is only a pole that fits over the forward end with a pin to drop in that secures it. It is kept above the S’ board bunk. When I visit “Hiran” again I will take photo’s. It has not been used in an emergency, but seems to control the rudder. The length is important as it is used in the confines of the rear cabin and would mean an open hatch. If there was a real problem I am sure that an open hatch would be worth the suffering.
