Pontoons have always been synonymous with entertaining, but the Mandalay Bar takes it to the extreme. As the name implies, an actual bar occupies the boat’s aft deck. It features a faux-granite countertop, three stools and stainless-steel cabinets. Click a switch, and an optional wineglass/plate holder rises from the bar top. Another counter sits behind the helm, with an optional refrigerator below. Someone’s living large.
