While in Bermuda one spring, he looked at a Bermudian Six Metre, the Saga, owned by Kenneth and Eldon Trimingham, and knew instantly that he had seen the prototype of a racing class boat.

The result may be considered a reminder of yachting's "Golden age" with the traditional metre-boat's long overhangs, graceful sheer, deep, narrow hull, and lofty rig.

After the liberation of Norway, construction resumed at Fredrikstad with boats going to San Francisco, Sweden, France, Oyster Bay, and Cowes.

Fiberglass construction was introduced in the 1960s with great care taken by the class to ensure that the wood and glass yachts could race on an equal basis.

In the next 28 matches, from then to 1964, held to compete for the cup (21 in Bermuda, and 8 on Long Island Sound), the Americans won 13 times, and the Bermudians 16.

Yachts from the International One Design class are used for the annual Bermuda Gold Cup as part of the professional World Match Racing Circuit.

Since its founding, the International Class has remained committed to the tradition of testing sailing skills in equally equipped yachts.

The Class' extensive one-design rules endeavor to ensure that the hulls, rigs and sails of the racing yachts are near equal as possible.

The chosen sail (mainsail, jib or spinnaker) is ordered in a single lot from the local fleet's official sailmaker, who pledges to make them as near equal as possible.

The result of this unique sail purchase program is a racing fleet of equally equipped boats that are maintained at a low cost to the individual owners.

"Bill" Luders Jr., Emil Mosbacher Jr. and Roderick Stephens Jr. codified the ethos of the class to prevent it moving away from its intended single design nature.

[4][5] Today, there are three authorised builders of boats for this class: Tjorns Yacht Service, in Sweden, and South Shore Marine and Tern Boatworks in Chester Nova Scotia.

The most recent all wooden IOD, built from the original 1936 drawings, was constructed in 2009 by Tern Boatworks,[4] in Chester, Nova Scotia.
