Together at last

Hessen latest build, Project Neptune, had its hull and superstructure joined together.

15 December 2017


On 25 November, 2017 the joining of hull and superstructure of YN 18556, Project Neptune, took place at the shipyard in Oss.

Project Neptune is yet another example of Heesen‘s expertise in creating extremely efficient and luxurious custom yachts. British design firm H2 worked on the Heesen pre-engineered FDHF platform to create an innovative, timeless sleek profile that still retains the Heesen family look and feel.

The design includes tenders conveniently stored on the forward deck, covered by hatches and invisible from the profile. The subtle but different paint scheme with the addition of metallic silver paint on the transom, wing station and mast, will make Project Neptune stand out.

Project Neptune sports a steel hull and complies with Lloyds 100A1, SSC Yacht, LMC Large Commercial Yacht LY3 and IMO Tier III exhaust emission regulations. Powered by twin MTU 8V 4000 M63 engines, she will reach a maximum speed of 15.5 knots with a cruising range at 13 knots of 4,300 nautical miles.


The Owner appointed Reymond Langton to create a bright and elegant interior with a contemporary design interwoven with subtle design details and artworks to create a rich but refined atmosphere.

The interior layout makes the most of the 770GT by offering an impressive 85-square-metre owner’s apartment set forward on the main deck comprising a private gym with steam room, office, full-beam bedroom and bathroom with central bath tub and shower stall accessible through His and Hers walk-in wardrobes.

There will be grandiose accommodation for eight guests in four suites on the lower deck, all with king-size beds and large en-suite bathrooms. A fifth double cabin is located on the bridge deck. Both owners and guests will be efficiently and discreetly serviced by the 13 crew thanks to separate crew corridors and stairs

The interior architecture throughout the main and upper deck living spaces is in light fiddle back sycamore combined with pale taupe leathers, bronze inlays and white onyx, with clean, simple lines combined with understated geometric motifs.

The fabrics and soft furnishings add hints of colour and pattern that draw in the eye and define the individual character of state rooms and saloons.

A further layer of interest is created by the inclusion of custom artworks in glass, gypsum, resin and bronze that echo and emphasize and add a glamourous sparkle to the understated foundation.

With tenders conveniently stored under hatches on the foredeck, the lower deck beach club is designed to accommodate the various water toys to entertain the guests, and is accessible from the main deck aft terrace via an internal stair case. A 3.5 metre long fixed swim platform provides easy and comfortable access to the water. This space offers a relaxed variation on the themes of the other guest areas with warm teak, blue backlit panels and bamboo detailing that blends seamlessly with the ocean beyond.
