The Blue Jay is an American sailing dinghy that was designed by Drake Sparkman of Sparkman & Stephens as a trainer for the Lightning one-design racer. The Blue Jay was first built in 1947.

Production

The design has been built in the United States by a number of manufacturers over the years, including the Clark Boat Company of Kent, Washington, Lippincott Boat Works, Beaton Boat Works, McNair Boat Works, Saybrook Yacht Yard and Formula Yachts of Groton, Connecticut. The current builder is the Allen Boat Company of Buffalo, New York.

The International Blue Jay Class Association owns two hull molds for the design, which were donated to the club by past builders, Formula Yacht and Saybrook Yacht Yard. These two molds have been loaned to the current manufacturer for production use.
