My 1984 Catalina 27 has had some lateral play in the tiller for some time - but following a grounding, it has become significantly greater. Sooo, I tried to tighten the bolt which which goes through the rudder shaft ( it was very loose) was very loose and it immediately sheared. I have a few questions: 1) if the remaining part of the bolt comes out, will I drop the rudder (the boat is in the water), 2) is the lateral play due to this bolt being loose or is it the fiberglass sheath for the rudder shaft and 3) does the boat need to be pulled to fix these issues. Thanks.
