An article in The New York Times on Tuesday reported that J. Darius Bikoff, the multimillionaire owner of Vitamin Water, is among the principals of ED40, a limited liability corporation that purchased the East Deck Motel at Ditch Plain in Montauk in the fall for a reported $15 million. It seeks to develop the property as a private club with a restaurant, spa, 8,000-square-foot pool, underground parking, and other amenities. None of the names of the corporation’s shareholders had been made public.
