History
The International DN Ice Yacht Racing Association (IDNIYRA) was founded in 1962. The DN is the world's most popular iceboat. It got its name because its original design won a 1937 contest sponsored by the Detroit News.
The DN is 12 feet long and 21 inches wide, with a sail area of 60 square feet. It has a top speed of about 60 miles an hour.
The IDNIYRA has approximately 2,000 members, split about evenly between North America and Europe. The site of the association's annual world championship alternates between the two continents.
