With more than 6000 sold, the Catalina 30 is one of the most successful production sailing yachts in history.
During the long production run of this basic model there were a great number of variations with standard and tall rig configurations, each with a bowsprit option, and also including shoal, wing and deep fin keels.
A MK II version began around hull# 3300 (1986).(T-shaped cockpit is the most notable change)
The Mark III (1994) (walk-thru transom with boarding/swim platform standard though offered as an option on earlier models.)
Aux. power:
The early Yanmar, Universal 5411 and Atomic-4 engines were phased out in favor of the 3-cylinder Universal M-25 diesels during the middle 80s.
