Deep cold brought a rare sight back to New York’s Great South Bay this week. With the bay frozen solid, iceboats were able to sail once again between Long Island and Fire Island. Video captured February 4 shows Miss Clella, a wooden iceboat built in 1969, gliding across the ice under sail power alone. Iceboating was once common here, but strong freezes like this haven’t happened regularly since the 1970s and 1980s, making conditions this week a throwback decades in the making. | WeatherBug
