The International One Design (IOD) is a class of sailing boat that was first designed in 1936 by Bjarne Aas of Norway. It was originally intended as a racing yacht for the Royal Norwegian Yacht Club, but its popularity quickly spread to other countries, leading to the establishment of the International One Design class.
The IOD is a keelboat with a length overall of 33 feet (10.06 meters) and a waterline length of 22 feet (6.7 meters). It has a beam of 6 feet 10 inches (2.08 meters) and a draft of 4 feet 6 inches (1.37 meters).

The design of the IOD is known for its classic lines and elegant appearance. It features a long overhang at the bow and a graceful sheer line. The boat has a traditional wooden construction, with a planked hull and a wooden deck. However, in recent years, some fiberglass versions of the IOD have also been built.
The IOD is a strict one-design class, meaning that all boats are built to the same specifications, ensuring fair competition. This makes it a popular choice for racing enthusiasts who enjoy the challenge of competing on equal terms. The class has a strong international following, with fleets located in various countries, including the United States, Canada, Bermuda, Sweden, and Norway.
The IOD is known for its excellent sailing characteristics. It is a responsive and nimble boat, capable of reaching high speeds and maneuvering easily. It is often sailed with a crew of four or five people, including a helmsman, a mainsail trimmer, a jib trimmer, and one or two crew members on the foredeck.
The IOD class holds various regattas and championships throughout the year, attracting sailors from around the world. It is also a popular choice for recreational sailing, with many owners enjoying the boat's classic design and timeless appeal.
Overall, the International One Design is a revered sailing boat class that combines elegance, performance, and competitive racing. Its enduring popularity and dedicated following speak to its status as a true classic in the world of sailing.
