Beach Club

A true beach club should be a waterside lounge and terrace. Usually at the stern, a beach club might open on one, two or three sides of the yacht. It should be practical, able to withstand plenty of use, watersports and saltwater, but also luxurious, creating a spectacular retreat day or night.
