Catalina Yachts Inc is still in business in Largo, FL and may be able to help you. Whether they still have masts to fit a 1984 C22 I can't say. I think there were two different masts used on the 22, one oval shaped (flat on the sides) and the other elliptical shaped (curved on the sides). If you find a mast with the matching profile and it is too long it can be cut down. Howerver, there are several considerations to cutting. You will want to make sure the spreader brackets mount at the same height above the deck as the old mast or your shrouds may not fit.
