rigging. Catalina uses closed turnbuckles,stainless tube over brass turnbuckle, naturally the tube corrodes to the brass. So, first try to move all those stainless covers up to see if you can access the turnbuckles. Other than tuning, your rigging may be okay. Probably need to reseize the shrouds because it's often overlooked. So, free the turnbuckles, inspect and try to tune.You can have a rigger do an inspection for about $300 if necessary. As Alan mentioned headstays are often hidden in furlers, are pretty critical, and often susceptable to unseen damage. If you go to the trouble to remove the furler might be a good idea to replace the headstay and not worry about it.
