Neptunus builds a high quality semi custom yacht in St. Catherines Ontario. This express cruiser with hardtop owner will consider trades for residential real estate or a smaller power boat and cash. She is loaded including an electric sun roof, hydraulic swim platform, Satphone and SatTV. She was repainted with Imron in 2011, just had a bottom paint job in 10/14, and her engines serviced 2011.

General Description & Accommodations

During the construction phase additional layers of glass reinforcements were added to the laminates well as additional longitudinals in the structure. Since the yacht was original to be stored on a lift out of water when not in use these additional reinforcements enhanced the structural integrity of the vessel both while on the lift and when at sea in that the structural rigidity of the vessel was increased. This attention to the rigidness of the vessel coupled with the larger Series 60 MTU 825 Hp engines combine to produce faster cruising speeds at 28 knots and top speeds in excess of 32 knots, more than other Neptunus 56 Expresses.

This yacht is a great family boat for entertaining as there is a secure feeling of openness in the enclosed upper salon/Helm area where views abound in an atmosphere where everybody is able to be together in comfortable dry surroundings. Forward is the Helm area with a Stidd captain’s chair and bench for 2-3 others.

Entry to the aft deck from the Upper salon is through the dual opening glass door which creates an open entertaining area where there is a large comfortable seating area complete with cockpit table, BBQ, icemaker and sink. The cockpit sole is teak enhancing the atmosphere of the cockpit.

The hydraulic swim platform is gated for safety and is accessed via a starboard staircase. There is also access to storage in the lazarette where there is a separate washer and dryer and access to the engine room from the cockpit.

Back inside the vessel and down a few steps you enter the galley and lower salon areas. The galley is large and easy to navigate with refrigerator/freezer and a built in dishwasher. The lower salon settee is  also  large  and  comfortable  and  has  a  36"  LCD  TV.   The flooring in the galley is granite while the balance of the lower salon sports the warm patina of natural cherry flooring throughout making the salon a snap to keep clean.

Aft is the master Stateroom with separate en suite head and shower while the VIP forward with its separate head and shower completes the Accommodation Plan.

The fore deck is fitted out with a large spacious sun pad.

Upper Salon/Helm

There is a built in LCD TV aft and to port with a stereo surround sound system and reception for satellite TV. The Helm features comfortable  captain’s  chair  and  addition  seating  so  everyone  may  be  together  while  running  the  boat.  All  controls  are   conveniently located to the Helm as are the navigation/communications instruments. An additional air handler under t he Helm provides additional cooling for this area.

Side windows lower electrically to allow fresh air into the cabin and for communication during docking procedures. There also is an electrically opening overhead sun roof for additional air and sun when d esired. When it is not desired and the sunroof is closed there is a manual sliding cover to prevent radiant heating from the sun within the enclosed opening.

Galley/Lower Salon

The Galley is below and to Port. Included are custom counter tops, dual side by side Sub Zero refrigerator and freezer. Flush mounted 3 burner Princess electric stove, built-in microwave, built-in space saver coffee maker. Large stainless steel sinks and ample storage.

Hull deck and all structures are constructed from fiberglass laminates. Longitudinal and athwart ship stringers reinforce the whole hull.

The  vessel’s  structure  and  laminates were increased during the construction phase in order to further re-enforce the hull as the boat initially spent most of its time on a lift and the owner wanted to ensure there was no movement at all in the boat while in storage.

All partitions and re-enforcements are constructed of plywood or foam and are laminated to the hull on both sides. The engine stringers run from bow to stern and incorporate the engine mounts where steel top plates are embedded for the engine mounts.

The deep Vee hull coupled with a 19.5 degree dead rise aft has been designed to ensure a vessel with excellent seafaring qualities and a dry ride. Special attention has been given to the ratios between installed power, speed, and fuel efficiency.
