Project Petra revealed by RMK Yachts

Turkish shipyard RMK Yachts has unveiled its latest collaboration with Milan-based design studio Hot Lab, part of the Viken Group: a 50-metre ocean-going explorer yacht concept called Petra.

The companies are long-standing partners. Previous Hot Lab-RMK collaborations have included the refit of the 45-metre Keyla (winner of the 2014 World Superyacht Award for Best Rebuilt Yacht) and the RMK 5000 Explorer concept, along with several other remarkable designs.

As the latest flagship to emerge from the yard, Petra builds on RMK Yachts’ well-respected heritage of robust engineering and quality craftsmanship while introducing a more lifestyle-driven, versatile approach to yacht design.

The 50-metre Petra is available in three versions: Aura, Core and Infinite. As three complete interpretations of the same platform, they vary in outfitting philosophy, layout solutions and exterior finishes.


Petra Aura

‘Aura’ is the most lifestyle-orientated yacht. Softer in character, warmer in atmosphere and conceived for owners who prioritise comfort, conviviality and a more relaxed onboard experience. Appealing to dynamic, next‑generation leaders, ‘Aura’ includes an extra guest room on the main deck, more social spaces, and an entertainment room on the lower deck.

‘Core’ is the purest expression of the concept: balanced, essential and closest to the original spirit of the design. It is the version that most directly expresses the synthesis between explorer functionality and Italian clarity. Designed for intimacy, comfort, and family life, ‘Core’ offers private retreats and warm spaces to create lasting memories, complemented by a spacious main deck pantry and the signature owner’s balcony.


Petra Core

‘Infinite’ is the most expansive and experience-driven variant. It is designed for owners looking for maximum flexibility, more generous spatial scenarios and a stronger sense of openness toward the sea. ‘Infinite’ is a true explorer with ice class notation, helideck, optional hybrid propulsion, large tender and crane capacity, water sports storage, and a large main deck pantry.

Conceptually, Petra stands out amongst her competitors on the market due to her combination of genuine explorer credibility with a highly resolved design language which is clean, intentional and architectural.


Petra Infinite

Built with an explorer-appropriate steel hull, aluminium superstructure and teak decks, the material approach on board Petra is based on authenticity and tactility.

Her palette will be built around natural woods, refined stones, technical surfaces, leathers and textured fabrics — materials that express durability and quality, but also warmth. The goal is to avoid anything overly decorative and instead create an atmosphere that feels precise, calm and enduring.

Petra can be described as a true ocean-going explorer, thanks to her steel hull, aluminium superstructure and impressive range of approximately 4,000 nautical miles, with a maximum speed of 16 knots.

Petra is also notable for her ability to carry and store large tenders, with fold-down bulwarks that transform the garage area into a beach club once the toys are launched. Furthermore, the ‘Infinite’ version is fully exploration-ready with ice class notation, hybrid propulsion option, and long-range capability. She can safely travel to polar regions, remote islands, and transoceanic routes.
