About the DN iceboat
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).
