Full Details

This 56' Neptunus "Flybridge Model" offers more than any other similar size yacht with her three generous staterooms, two heads, a lower helm station, an on deck galley and dining options forward of the galley or on the flybridge.

The interior has the perfect blend of high gloss cherry joinery, padded off white Ultra Leather paneling, silk fabrics with many relaxing areas and large cedar lined closets are throughout this yacht.

The deck plan of the main deck, below deck and flybridge are unique only to Neptunus designs.  The Neptunus Space planning is excellent and needs to be seen to be appreciated.

This particular 56' Neptunus has been very well cared for with most of her use in freshwater.

Upon entering the Aft Deck, with built in seating and port and starboard access to the side decks, the same deck level Salon is entered via a centerline door.  There is seating to both port and starboard with the full Galley two steps up on the port side.  Forward of the Galley is ample dinette seating to port with the Lower Helm to starboard.  Just aft of the Lower Helm are the curved steps to the accommodations below.  The Master is aft with an en suite Head.  Forward to starboard is a twin lower berth Guest Cabin.  All the way forward is the VIP.  The shared Guest Head is to port opposite the Guest Cabin.


The Salon is entered via a curved “Trend” stainless steel sliding door with a sliding insect screen and lined silk drapery.  The entire main deck is open with two levels of accommodation.  To port is an L shaped off white Ultra Leather sofa with storage below the cushions.  An oval cherry and burl wood coffee table lies in front of the settee.  The carpet in the Salon and throughout the boat was replaced (summer 2019).

To starboard is a matching Ultra Leather settee with cherry arm rests with storage below the cushions.  Just forward of the settee is a built in 32” LCD TV with a cherry countertop above.  Above is a cabinet with the KVH service port, Clarion AM/FM/CD/Sat radio, Clarion 6 disc changer, Glomex Terrestrial TV attenuator and wine glass storage below.

Also in the Salon are the Neptunus signature bi level cabin side windows each with silk drapes and an upholstered panel between.  Additional equipment includes Clarion stereo speakers, a Clarion subwoofer, a Walvac central vacuum unit and outlet, digital Marine Air AC controls.  Six halogen mini spots on a dimmer and rope lighting behind the upper valance provide lighting.
