The lower deck features 4 further guest cabins. The forward cabins are twins, each with their own ensuite bathrooms. The aft cabins can either be set up as separate double cabins, alternatively, can be opened to make a full beam VIP suite.

An elevator and central staircase connect the interior decks.

Up to 9 crew are accommodated in 5 crew cabins, including a separate captain’s cabin. All crew cabins are located forward on the lower deck.

EXTERIOR DECK SPACES

The primary guest exterior entertainment space can be found on the sundeck, which has been split with large, glass panels midship to shelter the aft area. The sundeck forward offers a large jacuzzi and sun pads. Midship, under the hard top shelter, can be found a dining table for 10 guests with further seating found aft around a firepit.

The bridge deck offers a private space for the owner, with direct access out of the master cabin.

In addition, there are walk around side-decks leading to the flush foredeck. The main deck aft accommodates the primary guest tender to port, with additional guest seating to port. The main deck aft leads down a central staircase to the generous swim platform. There is a secondary tender garage forward on the main deck, to accommodate the rescue tender and jet skis.
