Sea Axis Yacht Description

Boasting impressive pedigree and Dutch build quality, SEA AXIS is truly a supreme motor yacht. 

She features Frank Mulder design, which is visible in her sleek lines. This impressive yacht has benefitted from constant and consistent maintenance and upgrades throughout her life, including multi-million dollar refits that ensured her pristine, turnkey condition. From a deck extension to the overhaul of many systems to the full upgrade of her interior, no expense was spared in elevating Sea Axis to her current condition.

SEA AXIS has been fully restored, with a commitment by her current owner to keeping her Dutch heritage intact.

Under previous ownership, a structural rebuild took place in Europe that spanned two years from 2009-2010.

More recent interior refurbishments took place in both 2015 and 2018, with SEA AXIS benefiting from extensive financial investments by highly experienced owners.

Highlights include:

  •  Extension of decks
  • Re-plating of hull sections

SEA AXIS has been maintained in ABS Class since her construction at Heesen Yachts, and she has crossed the Atlantic on several occasions.

With her economical Duetz engines, and Dutch seakeeping capabilities, she is very capable of long open ocean runs but is also quite comfortable cruising to hidden Caribbean anchorages.

SEA AXIS's interior layout and design were carefully constructed by European craftsmen, with a special focus on contemporary yacht features. She is adorned with rich wood paneling and cabinetry, creamy white furnishings and carpeting, and bold red accent pieces that lend energy to elegance.

Unobstructed design and a flexible main salon layout lend the ideal flow of circulation, adaptable to an intimate gathering or entertaining a more extensive guest list. The furnishings, finished in soft and supple white leather are elegant, understated and luxurious; the dining salon is furnished in a modern, comfortable style providing formal or casually elegant dining for up to eight guests.

Complimented by the main salon bar and surrounding oversized windows the main deck is thoughtfully arranged to create an inviting, warm, elegant space within which to entertain or simply relax.

The comfortable sky lounge, with magnificent views, has a dedicated office area and entertainment center, unparalleled for casual, indoor relaxation. With surrounding oversized windows, this cozy but vibrant space was thoughtfully designed to create an adaptable space within which to work, relax or entertain.

Her five guest staterooms all have private baths and accommodate up to 12 guests.

Sea Axis also has great outdoor living spaces. The aft extension on the main deck provides shaded dining for 12 guests.

Full walkaround decks provide easy access to the bow seating area and gracious, spiral stairways to port and starboard descend to a large swim platform.

The expanded bridge deck provides crane and tender storage but when the tender is launched, it serves as a perfect space for lounging. 

The new ‘tender and toy-free sundeck benefits from an easy flowing layout and the perfect combination of sun and shade. With an elegant, teak sole there is banquette seating forward with a raised observation bench at the center that adjusts to fore or aft viewing positions. 

Centered under the protective shade, the fully equipped U-shape bar seats six guests, and the large Jacuzzi is flanked by vast thickly cushioned sun pads.


SEA AXIS accommodates 12 guests in 5 staterooms. The master stateroom is located furthest forward on the main deck with a centerline, King-sized bed. The private ensuite is located aft, with a Jacuzzi tub, glass shower, his and hers sinks, toilet, and bidet.

Located on the lower deck midship are three additional staterooms:

  • 1 x King VIP centerline bed with ensuite
  • 1 x King VIP centerline bed with ensuite
  • 1 x (2) Twin beds with Pullman and ensuite

The remaining guest stateroom is located on the lower deck aft, with access via a staircase in the main salon:
