There is a whirlpool spa on the centerline forward with sun pads around and a forward-facing settee aft, ahead of the funnel area. Further aft is a gym, storage and the dedicated day bathroom for the inside/outside gymnasium, which has a steam shower as well. There is an elliptical and a treadmill. The sun deck bar faces aft and is accented by stainless bar stools. At the aft end of the sun deck is a U-shaped sofa that has a concealed crane behind. At first glance, there is no storage for a dinghy or rescue boat, until you notice the rails in the deck floor, that enable the U-shaped sofa to slide forward providing storage space for the rescue tender. This convertible feature truly maximizes the use of space and demonstrates the expertise gained from years of yacht building and the preliminary engineering that went into SIRONA III. There is an emergency generator in the funnel forward and accessed through the day bathroom.


Foredeck anchoring is all the way forward with a storage locker further aft which doubles as a seat. The lounging area on this deck is the “pièce de resistance” on SIRONA III. Beautifully laid out with seating, chaise lounges that tilt at each end and deep comfortable couches, all covered when needed by awnings making for an exceptional space, seen only on one other yacht!

The wheelhouse is also perfectly laid out for owner’s enjoyment and visibility with two place settees port and starboard, a central bridge chair and navigation table and a large settee against the aft bulkhead.
Captain’s cabin is aft to port with double berth, desk and good hanging locker space and a really large bathroom.
The ships office is to starboard aft of the bridge, before entering the foyer which accesses the circular staircase down to main and lower decks. A walk in closet, formerly a day bathroom, is inboard. This can be converted back to a day bathroom if required.
The bridge deck owner’s stateroom takes up the remainder of the internal area on this deck. There is an owner’s  office forward to starboard, opposite the owner’s bathroom which is really generous size wise with a circular whirlpool tub outboard, separate his and her sinks and separate toilet rooms, hers with a bidet. There is extensive hanging locker storage throughout the master suite area. The king berth faces aft in the owner’s suite and there are easy chairs, coffee tables and a vanity and desk area as well.
Circular sliding glass doors open up to the aft deck area with glass top table, and four two place couches around it.
The galley is all the way forward on the main deck to port. A chef’s dream with good windows and floor space. The crew lounge and separate crew mess are next to the galley and there is a starboard side shell door for loading from the dock, directly down to the lower deck storage areas. The galley and crew mess area on SIRONA III both have a sea view and are better than on yachts twice her size.  There is a main deck service pantry down the port side.
Aft of galley and crew area to starboard is a fantastic TV lounge with a large L shaped settee (with foldout bed) and adjacent day head bathroom with shower. (This can be comfortably used as a 6th stateroom). The TV console is in the center of this room aft. Large windows provide excellent views.
Proceeding aft through the main deck lobby with central staircase, the main deck lounge has a table and four chairs to port and a U-shaped couch around a coffee table to starboard and an electric piano located aft to port. There is a TV that lowers from the ceiling to port. There is a bar further aft on the main deck and the dining room is further aft, enclosed by sliding glass doors which open up for fantastic alfresco dining scenes, adjoining to the open aft deck with expansive seating area aft around a table with four additional chairs.
There are port and starboard staircases down to the swim platform and port and starboard curved staircases to bridge deck Owner’s deck.
There are 6 double and one single crew cabins forward, each with en suite bathrooms. The single (overflow) crew cabin on starboard side (in the storage/linen area on the GA) has a toilet and vanity and shares a shower with another crew bathroom. The laundry room is further aft.
The ECR is aft, ahead of the two-tiered engine room. The generators are in their own soundproofed room, aft of the engine room.
There are four guest suites aft, all with en suites. The forward two each have queen beds with inboard single beds, and each of these staterooms also has a Pullman berth above. Each stateroom can sleep four, ideal for families with children and very versatile for charter. Further aft are two king berthed staterooms.
The guest tender is stored in the tender garage aft and easily launched off the stern platform.
The tank deck below has massive storage areas for wine, dry stores and huge refrigerator and freezer capacity.
