SEDATION 4 Labyrinth floorplan
living without doors

Most yachts have way too many hinged doors.  Usable floorspace is substantially reduced to accommodate the swing-arc of each door.  Doors rattle in rough seas and doorknobs can bruise a passenger's hip when bumped.  Closed doors inhibit ventilation.  Open doors obstruct passageways.  In this early conceptual floorplan of SEDATION 4, the abundance of swinging doors is obvious.  Each bedroom had a 24" wide door.  Each enclosed head had a 20" wide door.  All closets had doors.  A privacy door was even planned at the entrance to the master suite.  What was I thinking?!

SEDATION 4 has two private suites, albeit rather commodious for a vessel of her size, so privacy is inherent since each suite occupies a separate hull.  In this iteration, two 18" doors remained on each outboard hanging closet but these were subsequently changed to sliding mirrored panels.  Pocket (sliding) doors were designed for the heads in this second generation design and bedroom doors were eliminated completely.  My only justifiable application of a door is the soundproof Machinery Room entry.

Pocket doors are very practical but traditional implementations are rather heavy, complex and increase effective wall thickness.  I borrowed a design feature of public restroom's toilet stalls and designed a large air gap at the top and bottom of each sliding panel.  This enhances ventilation significantly and reduces door weight.  The tinted Lucite® panels are attached to heavy-duty drawer slides which are fastened to the inner surface of each heads' longitudinal wall.  The slides are less than 3/8" thick so increased effective wall thickness is minimal.  When the heads are not in use, the doors are slid into the open position.  The light and ventilation from the heads' portholes, now, contribute to the vessel's overall  comfort.  Note the dual sliding doors on the closets which also increase effective floorspace.  I decided to keep the full-length mirrored doors on the forward closets since these may be swung open for viewing from the queen size berths ;}

Privacy within each hull is obtained by staggering bulkheads and doorways to establish a labyrinth.  Line-of-sight is obstructed by these staggered features.  In this snapshot, looking forward from inside the machinery room, light from the guest stateroom is barely visible.  Once the machinery room door is installed, this line-of-sight will be eliminated.  The shower wall, just forward of the stairway, provides privacy for the bathroom and the head's aft wall screens the stateroom's dressing area.
