Most yachts are built to sail the waters of the Caribbean or Mediterranean. The Kilkea Superyacht is designed to go wherever you want. Based on a supply-vessel platform, it measures nearly 270 feet long with a 59-foot beam, and has a steel hull certified for operation in light ice. Yet it still offers resort-class accommodations for up to 36 guests, multiple swimming pools, options like a submarine dock, underwater observation room, or on-deck soccer pitch, and, of course, a helipad with hangar. It can travel for up to a month without making landfall, has a top speed of 15.4 knots, and a cruising speed of 12 knots, making it an ideal mobile base for the adventurous mogul.
