Circulation is available on both sides of the bed, maintaining symmetry and ease of movement. To starboard, a built-in upholstered settee runs beneath the window line, providing a secondary lounging area within the suite. To port, a dedicated vanity and desk area is seamlessly integrated into custom cabinetry and paired with a swivel chair and additional drawer storage. The suite features a split-level configuration that enhances privacy and separation. Forward and down a few steps, a walk-through dressing area provides generous locker space, hanging storage, and cabinetry, creating a proper transition zone between sleeping quarters and the ensuite. The dressing area leads directly into an expansive ensuite head finished in marble, featuring a full walk-in shower and refined contemporary detailing. The layout provides a true owner’s apartment experience rather than a conventional cabin arrangement. With its skylight glazing, neutral palette, and integrated seating and storage, the owner’s suite prioritizes light, volume, and modern design. The result is a private living space that feels residential in scale and execution, offering comfort, separation, and architectural presence within the yacht.

Enclosed shower compartments with glass doors
Stone or solid-surface vanity countertops
Integrated sink basins
Mirror panels with overhead lighting
Gloss white cabinetry
Built-in storage below vanity
Modern marine-grade fixtures and hardware
Proper standing headroom

The layout of each ensuite is efficient without feeling confined. The use of light-toned materials and reflective surfaces enhances perceived volume, while consistent finishes maintain cohesion throughout the accommodation deck.The VIP ensuites are slightly more spacious in footprint, while the twin cabins retain full functionality with private shower and vanity arrangements.
Fifth Cabin - Flexible Suite:The fifth stateroom is currently configured as a private lounge and gaming area but includes a full ensuite head and convertible sleeping capability.

Built-in sofa seating
Pull-out sofa bed
Integrated cabinetry and storage
Full private ensuite
This space operates effectively as a secondary media room, children’s lounge, or overflow sleeping cabin.
Historically, prior to the 2015/2016 refit, this cabin functioned as the captain’s cabin and included direct stair access to the galley. That staircase was removed during the redesign when the corridor was reconfigured to create the present entrance from the main foyer.
Because the cabin retains full ensuite facilities, it can easily serve as:
A full-time sixth stateroom
A dedicated captain’s cabin
A children’s playroom
A private office or media lounge
This flexibility is a strategic advantage for buyers who prioritize operational customization.
