Loosing a rudder is probably the worst with the exception of loosing a mast.
The easiest way to compensate for lost steering is to simply create drag past the stern. Simply put things like a sea
anchor, old tire (sometimes not easy to come by at sea),
anchor not dragging, extra sail on a
line, bucket on a rope. Well you get the idea, and if any one of these don’t work just add to the list.
By creating drag you will be able to steer the boat. Takes a little getting use to and does require a little work.
