DETAILS

Built in steel and aluminum to a design penned by A. Vallicelli & C. Yacht Design, K-584 sports a “masculine” exterior with “military flavor” and a red stylized “K” towards the bow.

To facilitate the yacht’s upcoming adventures, K-584 carries a 6-metre Tideman tender on her aft deck where a two-tonne HS-Marine crane takes care of launching and retrieving operations. The lower aft deck features a large swim platform with an adjacent fully equipped diving area designed for serious underwater expeditions.

Powered by 2 x MAN D2868 LE 425 engines delivering a top speed of 14.00 knots and a range of 6,000 nautical miles when cruising at 10 knots. Maximum comfort, with noise and vibrations at an incredible low level.

The entire upper deck is dedicated to the owner’s stateroom with a master cabin and a private outdoor terrace offering 360-degree views.

The smooth cruising of K-584 guarantees extremely high comfort for your precious time while relaxing onboard and enjoying your journey in total privacy.

Working closely with the Owners throughout the whole project, Architect Pierluigi Floris signed the “modern but cosy” interior, which can accommodate up to 10 guests across five cabins. 

Walking though the library and the cigar humidor to the gym and yoga area all the way to the VIP Cabin with a Furo bath. Port side directly connected to the crew area and the galley.

Three guest cabins with en-suite bathrooms and a very comfortable crew area amidship with direct access to the engine room and technical areas.

The engine room and the exploration room are directly connected to the crew area for easy access.
