DN ICEBOATS RACING ON CANANDAIGUA LAKE The DN class is the nearly universal standard for single person iceboats. They're cheap, fast and uncomfortable enough to make the driver feel satisfactorily macho. The smooth expanse of the lake and the impending squall moving in from the northwest are fairly typical during winter, but getting sufficient ice has become a problem in the Finger Lakes during recent years.
