56′ Neptunus Flybridge MIMI Walkthrough

56′ Neptunus Flybridge MIMI 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 natural cherry joinery, padded light tan Ultra Leather paneling, silk fabrics. The hue of the Ultra Leather Whisper Walls and headliner in this area are unique to this particular 56′ Neptunus and provides a very rich look.

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.

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 rust colored Ultra Leather sofa with storage below the cushions. An oval cherry and burl wood coffee table lies in front of the settee.

To starboard are two matching barrel chairs with storage cabinets outboard. Just forward of the settee is a Samsung 32″ LCD TV on the cherry countertop above. Above is a cabinet with the KVH service port, Clarion AM/FM/CD/Sat radio and the KVH Sat controller.

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 Two Stage stereo speakers, two subwoofers, a Walvac central vacuum unit and outlet, digital Marine Air AC controls. Seven halogen mini spots on a dimmer and rope lighting behind the upper valance provide lighting. The upper valance delivers the air conditioning in an even flow throughout the Salon.

A bulkhead mounted swing arm lamp and footstool accompanies the two occasional chairs.


This open floor plan leads you forward and up two steps into the full Galley. The Galleys design is U shaped to port is well laid out for very efficient use and includes the following features:

Cherry plank flooring
Avonite countertops
Double stainless steel under mount sink w/removable Avonite covers

Dining Area

One step up from the Galley is the yacht’s Dining Area on the port side just ahead of and open to the Galley.

A curved settee faces aft but offers an excellent view out the large forward and side windows. A unique burl wood and cherry table folds in half for easy entry/exit. The tan fabric upholstered settee easily seats four and would be considered the best seats in the house while underway.

Also in this area is a skylight to the Lower Companionway, another Marine Air digital AC control and two directional halogen mini spots over the table.

The sole of this area is carpeted to match the Salon.

Also in this area are two more Clarion Two Stage stereo speakers and window defoggers.

At a landing at the bottom of the steps is a Whirlpool Thin Twin heavy duty washer dryer in a cedar lined locker behind cherry doors.

Continuing forward are carpeted steps going up, a skylight to the Dining Area above, equipment access below the sole, cherry handrails with hidden rope lighting and LCD mini lights at the steps.

Master Stateroom

At the bottom of the Companionway slightly aft is an arched cherry doorway that accesses the Master Cabin. A raised platform berth with two storage drawers and rope lighting below is positioned off the port aft corner maximizing the floor space of the cabin. The mattress is a Tempurpedic mattress. Twin brass swing arm lamps flank the upholstered headboard that sits upon a mirrored bulkhead. To port is cabinetry forming a nightstand with a drawer below, bookshelf above and two opening stainless steel portholes with drapes above the bookshelf. Next forward is access to the en suite Head.

To the starboard side of the berth is a nightstand with three drawers below and an adjacent cabinet with three additional drawers, between them is a cherry cabinet.

Next forward is a large "almost" walk in cedar lined closet with a light, hidden storage, a digital safe and a dressing mirror inside the door.

At the foot of the berth is an upper cabinet with a built in RCA TV/VCR combo and a lower cabinet with a drawer and two curved doors below. Below is a Clarion AM/FM/CD player.

Above is an opening stainless steel porthole behind a Duette shade with rope lighting for accent and three overhead mini spots. Above are four mirrored medicine cabinet doors and a mirror angled to the ceiling for perfect use. The stall shower has a hinged clear glass door, a handheld or wall mountable Grohe fixture, soap and shampoo dispenser, a light, an exhaust fan and a grab rail.

Starboard Guest Cabin

Forward through the center Companionway and up three steps is the Starboard Guest Cabin with twin lower berths. Between the berths is a three drawer cherry nightstand with two brass swing arm lamps above. Beneath each berth is one large and two small drawers.

The outboard berth has two opening stainless steel portholes with drapes and five cherry cabinet doors above.

At the foot of the outboard berth is a cedar lined hanging locker with an auto light and a Sony DVD player within. A Panasonic 15″ LCD TV and a Clarion AM/FM/CD stereo face the berths.

Also in this cabin are two reading lights, digital AC controls, two Clarion stereo speakers and rope accent lighting below the berth and at the valance. A hinged access panel gives great access to the back of the Helm and associated electronics. A hidden third Raymarine 215 DSC VHF to take the place of the Pilothouse or Icom VHF as needed.

Guest Head to Port

Across the Companionway from the Starboard Guest Cabin is the Guest Head with two access doors, one from the center line Companionway, the other from the VIP. It features a custom Noche Travertine tile sole, bow front vanity cabinet with an under mount sink on the Avonite countertop. Above there are three mirror front medicine cabinets. Below the medicine cabinets is an opening stainless steel porthole with Duette shades. The toilet is a Raritan Atlantis model. The stall shower has a tempered glass door, handheld or wall mounted fixture, a light, a soap dispenser and an exhaust fan.

Plenty of mirrors including the overhead and three halogen mini spots offer excellent lighting.

VIP Cabin

The VIP Cabin is all the way forward and rivals many Master Cabins of similar sized yachts. The queen size berth with innerspring mattress is off the forward mirrored bulkhead with an upholstered headboard above. Below the berth are rope lights and two storage drawers facing aft. Above the berth is a round Bomar escape hatch with screen or privacy cover for emergency escape and ventilation and two separate halogen mini spots as reading lights. To both port and starboard are seven cherry cabinets. Below are full drapes and rope lights with one opening stainless steel porthole on each side. Built in cabinetry form nightstands both port and starboard. Aft to port is access to the Guest Head. Aft to starboard is a cedar lined hanging locker with auto light and a central vacuum outlet.
