The world’s oceans hold endless possibilities, and few vessels embody that spirit of boundless exploration like MASTER: Travel without borders. Crafted by ICON Yachts, a Dutch shipyard celebrated for its innovative conversions, MASTER is a 70-meter explorer yacht designed to traverse the globe without limitation. Originally an offshore rescue vessel, this ambitious project transforms a utilitarian ship into a luxurious, eco-conscious superyacht capable of reaching the most remote corners of the planet. In this article, we’ll dive into how MASTER redefines yachting by blending cutting-edge technology, sustainability, and a passion for unrestricted adventure.
The Genesis of MASTER: Travel Without Borders
Every great journey begins with a vision. For ICON Yachts, that vision took shape when an experienced superyacht owner approached them with a dream: a family-oriented vessel that could explore the world while remaining suitable for charter. After considering a new build, the owner pivoted to a conversion project, captivated by the potential of repurposing an existing platform. Thus, MASTER was born from the hull of Ocean Ness, a 2001-built offshore rescue ship from Kleven Verft in Norway.
The decision to convert rather than construct anew wasn’t just practical—it was sustainable. By retaining 95% of the original structure and extending it by four meters, ICON Yachts minimized the environmental toll of raw material extraction. Consequently, MASTER: Travel without borders stands as a testament to resourceful engineering, proving that luxury and ecological responsibility can coexist harmoniously.
A Design Built for the World
What sets MASTER apart is its go-anywhere capability. Designed in collaboration with Espen Øino International, the yacht’s exterior reflects a rugged elegance suited for polar regions, tropical waters, and everything in between. The conversion process, currently underway at ICON’s Harlingen shipyard, includes a diesel-electric hybrid propulsion system. This setup allows for near-silent cruising at seven knots, reducing noise pollution in sensitive marine environments.
Moreover, MASTER boasts a range of 6,000 nautical miles, making transoceanic voyages—like crossing the Atlantic or Pacific—a reality. The yacht’s two 1,100 kW Voith Schneider propellers enhance maneuverability, while lithium batteries and an advanced energy distribution system future-proof its operations. For instance, the propulsion can be upgraded to full diesel-electric down the line, ensuring MASTER remains adaptable as technology evolves.
Inside, Winch Design has crafted an interior that balances luxury with functionality. The owner’s suite, a sprawling 135-square-meter retreat, spans the uppermost deck, offering privacy and panoramic views. Five additional suites accommodate up to 12 guests, with flexible configurations for expedition staff or family. Therefore, MASTER: Travel without borders is as much a home as it is an adventure platform.
MASTER: Travel Without Borders and Exploration
Exploration lies at the heart of MASTER’s purpose. The yacht is equipped with an arsenal of toys and tenders, stored in over 800 square meters of space. Picture this: two 11.5-meter cranes launching submarines or tenders, a certified helideck for aerial excursions, and a 42-square-meter expedition area for scientific pursuits. Whether it’s diving into uncharted waters or landing on a glacier, MASTER enables experiences that defy conventional yachting.
Additionally, ICON Yachts has partnered with adventure specialists like Cookson Adventures to ensure MASTER delivers more than just leisure. The yacht supports marine research, conservation efforts, and educational outreach. For example, its onboard facilities can host scientists mapping the ocean floor or studying remote ecosystems. As a result, every voyage becomes an opportunity to contribute to global understanding and preservation.
The collaboration with Cookson Adventures, filmed in 2023 at the shipyard, highlights this shared vision. Nick Davies, Managing Director of Cookson, noted, “We’re designing complex, meaningful expeditions with purpose.” This synergy ensures that MASTER: Travel without borders isn’t just a vessel—it’s a platform for discovery.
Sustainability as a Guiding Principle
Sustainability isn’t a buzzword for MASTER—it’s a core value. ICON Yachts has integrated green technologies throughout the yacht’s design. Since 2021, the shipyard has operated on 100% renewable energy, a commitment mirrored in MASTER’s construction. The hybrid propulsion system reduces emissions, while the anchorless dynamic positioning system prevents seabed damage in fragile areas.
Furthermore, the yacht adheres to RINA’s Green Passport standards, ensuring environmentally responsible operations. Even the discarded parts from the original vessel were recycled or repurposed within the maritime industry. Consequently, MASTER minimizes its ecological footprint while maximizing its reach, embodying a new standard for eco-conscious exploration.
The owner’s brief emphasized this balance. “They wanted a yacht that could go anywhere without compromising the planet,” explained Stephan Vitus, ICON’s Head of Project Development. By marrying advanced engineering with sustainable practices, MASTER delivers on that promise.
MASTER: Travel Without Borders in Action
Imagine MASTER docked in a remote fjord, its helideck buzzing as guests return from a glacier trek. Or picture it anchored off a tropical atoll, tenders ferrying researchers to a coral restoration site. These scenarios aren’t hypothetical—they’re the reality MASTER is built for. Scheduled for delivery in 2025, the yacht is already poised to redefine global cruising.
During its transformation, MASTER has drawn attention at events like the Monaco Yacht Show, where ICON unveiled the project in 2021. Its ability to blend family-friendly luxury with expedition-grade capabilities makes it a standout. For instance, the top deck doubles as an entertainment space when the helicopter isn’t in use, offering over 200 square meters of outdoor living.
Moreover, the yacht’s versatility extends to its charter potential. With space for 12 guests and a crew of 18, plus room for six expedition staff, MASTER can cater to diverse groups—whether thrill-seekers, scientists, or philanthropists. Thus, it’s not just a private retreat; it’s a vessel for shared experiences.
The Technology Powering MASTER: Travel Without Borders
Technology is the backbone of MASTER’s borderless ambition. The diesel-electric hybrid system, paired with Voith eVSP propellers, ensures efficiency and silence—a rarity in yachts of this size. At 14 knots top speed, MASTER balances performance with endurance, while its 6,000-nautical-mile range opens up the world’s most distant destinations.
The yacht’s conversion also includes a technological overhaul. The wheelhouse, stripped of outdated equipment, has been upgraded for the next two decades of service. Meanwhile, the energy distribution system integrates lithium batteries, paving the way for future enhancements. As a result, MASTER is both a product of today and a vessel for tomorrow.

ICON’s expertise in conversions shines here. “We bring a unique skill set from commercial and superyacht sectors,” said Tony Gale of ICON Yachts. This dual perspective allows them to source robust platforms like Ocean Ness and transform them into something extraordinary.
