Rossinavi Launches First 48m Adventure Yacht Seazens

Italian shipyard Rossinavi has launched the 48m superyacht Seazens in Viareggio, marking its entry into the adventure yacht sector with a vessel designed for extended exploration and activities at sea.

Previously known as Project Berserk 47, the fully custom motor yacht features exterior design by Rossinavi, interiors by the Touch Studio and naval architecture by Arrabito Naval Architects. Built with a steel hull and aluminium superstructure, the sub-500GT yacht accommodates up to 11 guests across five cabins

A distinctive profile for adventure cruising

The custom yacht features a high, near-vertical bow, substantial hull volumes and a contemporary profile defined by horizontal lines and geometric glazing. A grey hull contrasts with the lighter superstructure, while continuous bands of upper deck windows provide panoramic views. Her fully custom design prioritises practical deck arrangements while retaining the appearance of a modern luxury superyacht.

Convertible cockpit accommodates two large tenders

The main deck cockpit accommodates two tenders, handled by a concealed crane with an 8.6m boom and 5.5-tonne lifting capacity. Once launched, the cockpit converts into an outdoor lounge using furniture stored below deck. Forward storage accommodates two jet skis and a rescue boat, while the upper deck features indoor and outdoor lounges. The sundeck includes alfresco dining with sliding wind panels, a bar and a forward pool with sunbathing space.

Flexible guest suites and onboard wellness

The motor yacht's accommodation includes a full-beam owner's suite on the main deck, while two lower deck guest cabins can be combined into a full-beam VIP suite with a private lounge. A lower deck indoor beach club incorporates a gym, sauna and shower, providing dedicated wellness facilities alongside the yacht's adventure-focused amenities.

She reaches a maximum speed of 15 knots and cruises at 12 knots, with a range of 4,000 nautical miles at an economical speed of 10 knots. Fuel capacity is approximately 65,000 litres, supporting her long-distance cruising capabilities.
