In the summer of 1975 Rodney Johnstone designed and built hull number 1 in his garage in Stonington, Connecticut. "Ragtime" would serve as the master mold for the subsequent hulls. This design allowed him to start the very successful J-Boat company with his brother Bob Johnstone. By 1978 the class was popular enough to hold a one-design regatta in Key West with twenty boats on the line.
New boat manufacturing has been done by multiple companies around the world in UK, France (only 5), Croatia, USA, Italy and Argentina. In the US, J/24s are built by US Watercraft. Italy could still build new boats.
As of January 2009, approximately 5,475 J/24s have been produced. Approximately 20 new boats were produced in 2008. The average price of a complete, new boat without sails was approximately £20,000. (31,370 USD)
The J/24 is a racing keelboat, built predominantly of fiberglass, with wood trim. It has a fractional sloop rig, a raked stem, a plumb transom, a transom-hung rudder controlled by a tiller and a fixed fin keel. It displaces 3,100 lb (1,406 kg) and carries 950 lb (431 kg) of lead ballast.
The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two straight settees in the main cabin. The galley is located on the starboard side just aft of the bow cabin. The head is located just aft of the bow cabin on the starboard side stowed under a table. Cabin headroom is 48 in (122 cm).
The international authority for the class is World Sailing, which cooperates with the International J/24 Class Association on all matters regarding the rules. Interpretations of these rules shall be made by the ISAF, which in coming to its decision may consult the International J/24 Class Association and the copyright holder. The International J24 Class Association (IJCA) has the sole authority worldwide for the conduct and management of the International J/24 Class. IJCA is a "not-for-profit" organization.
One reason for its popularity is that it is fairly easy and inexpensive to acquire a used boat and gear due to the large number of boats produced. There are 136 active fleets in the US alone, which offer a lot of race competition. This makes the J/24 a popular boat for beginners and experienced sailors.
In a 2010 review Steve Henkel wrote, "The boat is light and sails like a big dinghy. In anything over ten knots of air, 'rail meat' is needed to keep the boat on her feet going upwind, but the ride can be thrilling, We cruised her occasionally, and once or twice trailered her to Newport for a week’s cruise of Narragansett Bay, where there was a public park with a launching crane available. But we wouldn't recommend the boat if cruising is your main aim. Best features: This is a great boat to race if you like to socialize and want to learn how to race well. Worst features: With her 4-foot draft, launching at any but the steepest launching ramps is out of the question, Luckily, most places where J/24s are raced have access to a crane. The /24 has an eyebolt on the top of the keel for shackling to a crane hook. The crane can also be used to lift and set the mast, which steps not on deck but on the keel."
