Marty Van Lith reports this British Pathé link to ice boats in the Great South Bay, 1940. Title reads: "Pathetone Lightens The "Blackout" With - ICY SCOOTERS! Various shots of people skimming across the ice of a frozen bay in ice yachts - it looks like good fun! One of the boats tips right over, though the two men in it try to prevent it."
Modern photographs by Bobby Sterling, Winter 0f 2007. We call them ice scooters. These photographs were taken off the foot of Mott Lane, Brookhaven Hamlet. Their design has changed little since 1940.
