The Dolphin 24 is an American trailerable sailboat that was designed by William Shaw of Sparkman & Stephens as a Midget Ocean Racing Club (MORC) racer-cruiser and first built in 1959.
O'Day did not build the boat in-house, but contracted out construction to several different companies, including Lunn Laminates of Long Island, New York and later Marscot Plastics in Fall River, Massachusetts, a company that later became a subsidiary of O'Day.
It has a masthead sloop rig, a raked stem; a raised counter, angled transom; a keel-mounted rudder controlled by a tiller and a fixed long keel, with a centerboard.
The Pacific Dolphin boats have 310 lb (141 kg) more ballast and an outboard well instead of the optional inboard engine.
And she can flash ample canvas: The sail area-to-displacement ratio is around 18.2, and conservative by today's standard, but she’s not at all under-canvased.
These boats offer many combinations in sail power: symmetrical spinnakers, multiple jibs and overlapping genoas and everything in between.
Meaning for the brave and the physical, she will push her hull speed with a skilled crew; her balanced helm is easy on the hand.
