YN19755 Project Gemini - 2022

55m Steel

Evolutionary style

The 55m Steel encompasses proven efficiency with sophisticated style.
Advanced naval architecture from Van Oossanen utilises the FDHF hull form to ensure performance and power. Combined with exterior design by Omega Architects, she offers a spacious volume of 760GT.

Innovative use of glass throughout provides an abundance of natural light and choice of panoramic vista after panoramic vista. The full beam sky lounge and main saloon embody this. Floor-to-ceiling glass doors lead to outdoor seating, dining and relaxation areas, delivering a seamless connection between indoor and outdoor.

At the heart of the design is the owner’s stateroom, where an 82-squaremetre retreat awaits on the main deck. Elsewhere, ten guests are accommodated across five staterooms – all with en-suite facilities.

A unique dedicated wellness area is accessible via the beach club, with the sun deck incorporating plenty of room for soaking up the best of the yacht life. Powered by two MTU 8V 4000 M63 engines, the 55m Steel achieves a top speed of 15.5 knots with a range of 4,500 nautical miles at 13 knots.

First impressions

The full beam sky lounge is found on the wheelhouse deck and leads out to a spacious seating and dining area. A unique feature to the 55m Steel’s three sister ships, the VIP stateroom is also found on this deck. An additional comfortable seating area is located at the bow - ideal for taking in spectacular views whilst cruising.

Step aboard

Refined materials have been championed in this paired back and sophisticated interior by Italian designer Luca Dini. A geometric design language threads through the yacht creating clearly defined areas. Warm, full gloss, tay wood, mirrors, decorated glass and natural stones are matched with marine leather wall panels and doors and fabric-lined ceilings. Accents of metal, marble and glass are used to give the light and airy interior composition and focus. All views lead to the horizon in a celebration of floor-to-ceiling windows and large reflective surfaces.
