suggestions/advice anecdotes on how to jury/jerry rig a rudder on an unltd (SIC in this case) when the steering fails.
I am not asking for when the entire rudder fails or falls off - assume one just "bobs" - but rather ideas on how to jam the rudder when the steering has failed (broken screw, snapped cable, cable jumping loose from rudder post, etc). A board is very ungovernable when the rudder is "free" & pivots... being able to jam it gives significant control but how best to achieve that in rough water, 40kts of breeze & crew disappearing over the horizon.
