shoal keel 30
I have a 1977 with the 4'4" shoal keel. While I have not sailed it against the standard keel, I can say that it is quite satisfactory. If you are going to be racing you probably want the deeper keel. If shallow water is a concern where you are going to be sailing, it is nice to have the extra 11". The boat is very stable and forgiving. You can't get in too much trouble. I have had mine for 3 years and have been very pleased.The wooden spreaders if you have them might need to be replaced . Catalina sells an aluminum replacement kit which I had installed by the local Catalina dealer when I bought the boat. The only other problem I have encountered is a crack where the keel attaches to the hull. This is not a major concern and is fairly common with Catalinas. The dealer is going to repair it for about $500.This is a nice boat. I think you will be very happy with it.
