A Sixth Collaboration Between Vripack and a Turkish Naval Yard
Seven Seas was designed by Vripack for both her naval architecture and exterior styling, with the interior credited to Epiworks, and built at RMK Marine's Tuzla shipyard on the Sea of Marmara, the same yard Koc Holding has owned since 1997 and that also builds naval and commercial vessels up to 150 metres. Ocean Independence's own brokerage listing describes her as the sixth collaboration between Vripack and RMK Marine, a working relationship the two have used to develop a distinct explorer-yacht style within RMK's much broader commercial and naval order book.
She measures 36.86 metres length overall on an 8.38 metre beam, for a gross tonnage brokerage sources put at roughly 388 to 400 GT, built with a steel hull, aluminium superstructure and teak decks, a construction format shared with most full-displacement explorer yachts in this size range. RMK delivered her in May 2024, and she has remained in private ownership since, never entering charter service despite carrying accommodation and crew sized for it.
Modest Speed by Design, on Twin Caterpillar Diesels
Twin Caterpillar C32 diesels power Seven Seas, rated at 950 to 964 hp each depending on the source consulted, turning her hull to a 10 knot cruise and a top speed brokerage listings state as either 13.5 or 14 knots, a small enough gap to be rounding rather than a real disagreement. Two independent brokerage sources give her range as 4,000 nautical miles at 10 knots and 5,000 nautical miles at cruise respectively, a real discrepancy this entry cannot resolve from public sources and one a serious buyer should ask RMK or a surveyor to confirm from her own fuel logs rather than take from either listing.
Generators are two Caterpillar C4.4 units at 69 ekW each plus a Northern Lights unit at 32 ekW, and she carries zero-speed stabilisers, standard equipment on an explorer yacht meant to sit steady at anchor for extended periods rather than just to smooth a passage underway. Three separate generator sets, two matched and one smaller standby unit, is a configuration built for redundancy rather than economy, letting the smaller Northern Lights unit cover house loads at anchor while the larger Caterpillar pair stays reserved for passage-making and air conditioning. None of the brokerage listings found publish her fuel or fresh water tank capacity, an unusual gap for a boat marketed specifically on long-range, self-sufficient cruising, and one worth asking RMK to confirm directly against the RMK 122 design's own general arrangement drawing.
Ocean Independence's own brokers call her a very high-quality displacement vessel, a claim worth weighing against the EUR 2 million price cut she has already taken inside two years of ownership.
Five Cabins for Ten Guests, with Room for Seven Crew
The accommodation plan puts up to 10 guests in 5 staterooms, with room for up to 7 crew, generous crew provision for a 37 metre yacht and consistent with a boat built for genuine long-range, self-sufficient cruising rather than short coastal charters. That crew ratio, close to one crew member for every one and a half guests, is heavier than most flybridge motor yachts of the same length carry, and matches the pattern seen on other RMK-built explorer and naval-adjacent hulls, where redundancy and self-sufficiency shape the layout as much as guest comfort does. Epiworks' interior mixes wood-panelled staterooms, marble bathrooms and a modern galley finished in stainless steel, described in one brokerage listing as giving the impression of a luxurious living area with wooden accents throughout the main living spaces.
Outdoor space follows the explorer-yacht template rather than a flybridge cruiser's: jacuzzi and bar areas on deck sit alongside display and entertaining space, and one listing specifically frames the boat's appeal around her worldwide cruising capability rather than around onboard entertaining, in keeping with her modest top speed and long-range engineering. She has never been offered for charter, so unlike many yachts in this size bracket there is no public guest-review record of how the layout performs in active use, only the builder's and brokers' own descriptions.
A EUR 2 Million Price Cut Inside Two Years of Ownership
Brokers Alex G. Clarke at Denison Yachting and Jim Evans at SuperYachtsMonaco jointly market Seven Seas, and Boat International's brokerage coverage recorded the EUR 2 million reduction from EUR 13.9 million to EUR 11.9 million without stating the sellers' reason, a silence this entry should not fill with a guess. A roughly 14 percent cut inside two years of a 2024 delivery is a meaningful data point for anyone pricing a comparable explorer yacht, whether or not the specific cause was the boat, the broader brokerage market, or the seller's own circumstances.
RMK Marine itself has never published a new-build price for Seven Seas or for the wider RMK 122 explorer design she is built to, so the EUR 11.9 million current asking figure is the only concrete number available for the model, new or used. Ocean Independence's own listing copy calls her a very high-quality displacement vessel with large carrying capacity for worldwide cruising, marketing language that, as elsewhere in this entry, is kept separate from the verified facts around her price and specification.
A Yard Better Known for Naval Steel Than Yacht Glamour
Industry coverage of RMK consistently frames the yard through its engineering credentials, Lloyd's Register and ABS classification, MCA and SOLAS compliance and military-grade construction standards inherited from its naval and commercial work, rather than through the kind of lifestyle marketing a dedicated luxury yacht brand relies on. That reputation is real and earned: Nazenin V, Karia and the Oyster-designed Sarafin all won recognition at the World Superyacht Awards, evidence the yard can deliver to the same standard as far more yacht-focused competitors when the design brief calls for it.
What RMK lacks, by comparison with a Feadship, Oceanco or even a mid-sized dedicated explorer builder like Bering, is a deep public record of independent sea trials, owner interviews and brokerage history for its yacht side specifically, since most of the yard's output and reputation still comes from naval and commercial contracts rather than yachts. A buyer researching Seven Seas or any other RMK yacht should expect to do more of their own diligence on the yacht-specific track record than they would with a name that builds nothing but yachts.

| What to check on a used Seven Seas | Engine and generator hours on the twin CAT C32s and all three generators; verify her actual range at a chosen cruise speed against her own fuel logs given the 4,000 to 5,000 nautical mile discrepancy between published sources; and ask why her asking price was cut by EUR 2 million within two years, a question this entry could not answer from public sources. |
Cosa riferiscono armatori ed equipaggi
Brokers market her on build quality and range rather than speed or luxury features
Ocean Independence's listing copy calls her a very high-quality displacement vessel with large carrying capacity for worldwide cruising, a framing consistent with her modest top speed and long-range engineering.
Ocean Independence brokerage listingNo independent sea trial or charter guest account has been published
Seven Seas has never been chartered and no yachting magazine sea trial of her was found, so unlike many yachts in this size bracket there is no independent, hands-on account of how she performs at sea.

Cosa convince e cosa va valutato
Punti di forza
- Built by a yard with genuine naval and commercial engineering depthRMK Marine's classification under Lloyd's Register and ABS and its history building to naval and commercial standards up to 150 metres gives Seven Seas a construction pedigree that most dedicated yacht-only builders of similar size cannot match.
- Sized and equipped for genuine long-range, self-sufficient cruisingZero-speed stabilisers, a full-displacement steel hull and accommodation for up to 7 crew all point to a boat built for extended, remote cruising rather than short coastal hops.
Da valutare
- A EUR 2 million price cut inside two years is a real warning sign for resaleWhatever the cause, an asking-price reduction of roughly 14 percent within two years of a 2024 delivery is a meaningful data point a buyer of any comparable explorer yacht should weigh, and no public source explains it.
- Basic tankage and thruster specifications are simply not published anywhere foundFuel capacity, water capacity, gearbox make and thruster specification are all absent from every brokerage listing checked, gaps a buyer should have RMK or a surveyor fill in writing before making an offer.

A chi si rivolge: A buyer who wants a genuine steel explorer hull built to naval-grade engineering standards from a yard with a real commercial and military order book behind it, and who is comfortable that RMK's yacht-specific brand recognition and resale data are thinner than a dedicated luxury yard's.
Prezzo indicativo: RMK Marine has not published a new-build price for Seven Seas or for the RMK 122 design generally. She was first listed around EUR 13.9 million and was relisted in 2026 at EUR 11.9 million, a EUR 2 million reduction, through brokers Alex G. Clarke (Denison Yachting) and Jim Evans (SuperYachtsMonaco). Sources: Boat International, Ocean Independence.
