SPECTRAL 50M Yacht for sale

164' (49.99m)

The 164-foot (50m) SPECTRAL 50 is a new-build, ocean cruiser by exterior designer Christopher Seymour and design consultant Carl Esch to be built by the Dutch shipyard Bloemsma & Balk.

From an impressive 145-square-meter main aft deck to a 40-square-meter upper aft deck and an outstanding 75-square-meter sundeck, this superyacht offers expansive outdoor living for living the best of the alfresco lifestyle. SPECTRAL 50’s sprawling main deck aft features a pool surrounded by sun loungers, a lounge area and a bar — a retractable sun canopy provides shade. When desired the pool can be covered to provide more deck space. Additionally, there is the option for the pool to convert into a helipad.

This new-build yacht has an expectational beach club and garage transom, which allows the owners and their guests to relish endless days right by the water’s edge, enjoying the yacht’s plethora of tenders and toys.

SPECTRAL 50’s interior volume is just as impressive as her exterior with approximately 285-square-meters of interior guest living space. Guido de Groot designed the luxury yacht’s stunning interior. Her main salon, formal dining and skylounge provide the perfect spaces for entertaining. Large windows surround the main salon providing an abundance of natural light. In addition to expansive windows, the main salon blurs the lines between inside and out with two-fold out balconies. A luxurious staircase allows for easy access to her three decks of SPECTRAL 50.

Superyacht SPECTRAL 50 offers accommodations for ten guests in five sumptuous staterooms. Her owner’s suite, on the main deck, is a retreat complete with a private office, dressing room and en-suite bath. The superyacht’s additional staterooms are all located on the lower deck.
