The Catalina 30 is a series of American sailboats, that were designed by Frank Butler and later by Gerry Douglas.

[1] The Catalina 30 is a small recreational keelboat, built predominantly of fiberglass, with wood trim.

It has a masthead sloop rig, an internally-mounted spade-type rudder and a fixed fin keel.

[1] The Catalina 30 was inducted into the now-defunct Sail America American Sailboat Hall of Fame in 2001.

This design philosophy is perhaps best expressed in the Catalina 30, a racer-cruiser that set the trend for many of today's most successful lines and is itself still going strong after a production run of 25 years and more than 6,500 boats.
