The DN name originates from Detroit News, where the DN was first designed and built in the winter of 1936-1937. It was built in a hobby shop at Detroit News to fulfill the demand for a simple and affordable ice yacht. Since then, the boat has evolved considerably, but has not strayed away from the original parameters. The wooden hull is 12 ft in length and sits atop of an 8 ft wide beam known as the runner plank. Unlike a stern-steerer, the DN has a tricycle configuration, meaning that it has two runners (the steel skates that the boat rides on) aft on the outboard ends of the plank, and one steering runner forward at the very bow. Many newer boats feature upgrades such as lengthened insert runners and an extremely flexible carbon-fiber mast. The mast is 16 ft tall, allowing for a mainsail area of 60 sq ft, which is plenty when you’re sailing at these insane speeds.
