Here ya go
Okay Farmhand...........Look up and click on "Resources" then go to "Sailing Web Sites", then click on "Catalina 30 International Association" then click on "Catalina Technical Library" then click on "Catalina Library".......and you will see the hull numbers of the Catalina 30 relative to the year built and the factory changes. Looks like pedestal steering was offered as early as 1978! So, considering the thousands of hulls Catalina made, you know for certain that hulls built before 1978 most probably had tillers. Maybe tillers were custom orders on newer vessels. Good luck with your search.Bob'88 Mark II
