With two classes of ice boats, the Skimmer 45 and the DN, and the RC CR-914 sailboats there's something for everyone. Even if you are just curious, it should make for some interesting spectating (see iceboat video clips below). The DN has a very active international class association.
The DN is the largest iceboat class in the world, so named because it was the winner of an iceboat design contest sponsored by the Detroit News in 1937. That year the newspaper opened up it's shop to 50 builders who assembled the first fleet of "Blue Streak 60" iceboats (as it was originally named).
