The Dolphin 24 has been built by several different builders. The first was O'Day Corporation in 1960 although the boats were built by subcontractors. These subcontractors were Lunn Laminates, F.L. Tripp & Sons, and J.J. Taylor & Sons.
In 1965 Yankee Yachts started to build the boat. The first few were built from kits from O'Day. Pacific Dolphin started building the boats in 1977.
In 1973 the design was revised for a New Zealand builder as a fixed keel boat with a draft of 4.17 feet. The deck, house and rig were redesigned at this time.
These boats are not related to the Angus designed Olympic Dolphin 23.
