Flybridge

A superb place to enjoy days or nights on the water, this raised deck and driving position adds another dimension to yacht ownership and the driving experience.

Sirena 42M

Benetti Oasis 40M

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.
