There are two large cedar lined hanging closets one on each side of the room in front of the bed. A large in suite head with shower complete this elegant interior. All windows and door frames are heavy duty stainless steel with screen and screen door. There is a 24” flat screen TV with built in DVD player, and a Kenwood Bluetooth stereo system. The TV is wired so it plays through the stereo system. The rooms are all wired to the Satellite TV system so just add the service and all rooms have their own Sat TV. There are overhead lights, mode lights and reading lights all control by switches conveniently located on each side of the Queen Bed. There is also 12 volt outlet for charging or other uses.

The private mater bathroom is spacious and has plenty of storage cabinets. The Raritan Electronic heads are very elegant and are easy to control water usage. They run on 12 volts so are always functional. The shower is a curved corner unit. It has matching gold fixtures with a single water control. The shower has its own pump box which uses a “Gulper” 12 volt pump.

Port Stateroom/Laundry

The port state room consists of two large bunks, a stackable Washer/Dryer, and the battery/electronics control room. Unlike many bunk/single bed style rooms the beds are very long measuring 7.5 feet. Each bed has its own lighting control with overhead reading lights. The room has a flat screen TV with built in DVD player. There is a Kenwood Bluetooth Stereo that also has the TV as an input. This room has its own zone for heat/air with separate electronic control.

VIP Stateroom

The room has a 19” TV with built in DVD player. There is a Kenwood Bluetooth stereo system that has the TV as an input.

There is a large hanging closet in front of the bed and a floor to ceiling closet to the right of the bed. The VIP Stateroom has its own access door to the center head so when cruising with two couples each room has private bathroom.

Deck Equipment

Full walk-around decks with heavy duty stainless steel rails. The back bridge has a cover that extends from the fly bridge overhang to the back sidewall. This provides excellent protection for the boat and also privacy while in the marina. There is an aft transom door with steps down to a molded TNT hydraulic lifting swim platform. The built in molded rear platform is extended an additional 5 feet with the Hydraulic TNT swim platform. The TNT platform is controlled with either a connected cable remote or a wireless remote that is the primary control. The Dinghy mounts on the platform so loading is a breeze. The platform drops and the dinghy is simply slid over the mounts and the platform raised. There are several attachment point to use straps that secure the dinghy. On the back there is a transom shower with hot and cold water. There is a fresh water faucet that can be used as a boat flush down or to take showers. There is a Marquipt Davit on the aft. This has been converted to 12 volts so it works without the generator. There are many uses for the davit from having rope chairs, lifting propellers, lowering heavy objects into the engine room, or loading the dingy in case of a failure in the TNT.

The deck is equipped with heavy duty fenders, lines, courtesy lights, and stainless steel cleats. There are molded steps from aft deck to the bridge with excellent lighting. There are new cushions on the entire bridge area seating, bow cushion, windshield cover and port and starboard wing lockers.

Fly Bridge

The Neptunus 55 sedan flybridge is very spacious. A very expensive vinyl hard top was install along with full isinglass enclosure that protect the flybridge furniture and equipment from the elements and makes the flybridge very versatile. All of the windows have “U” shaped zipper rollups which allow the entire flybridge to be open in minutes. With the enclosure it is no issue to drive through rain storms or with strong head winds as the front window can be shut and provide excellent protection. There is seating for ten along with a table that can be use for dining, snacks, drinks or general purpose. The table is removable and the couch converts into a bed. The centerpiece unit has the drivers couch fore with a center icemaker and sink aft. On each side of the icemaker/sink are built in seating. The captain’s bench can seat three which makes for nice passages with guests. Built into to the overhead hardtop are LED color changing lights.
