Seven Seas

A full-beam master on the main deck is the layout decision that shapes the rest of Seven Seas: the guest cabins' location and the main deck stays open for living. RMK Marine built her as the RMK 120 in 2024, a steel-hulled explorer designed by the Dutch firm Vripack for genuine offshore distance. At 37 metres and 399 gross tons, she has the volume for that master suite without giving up guest space elsewhere.

Build and provenance

Vripack, the Dutch design firm, drew Seven Seas as a global explorer, and RMK Marine in Turkey built her to that design with a steel hull and an aluminium superstructure. Epikworks did the interior in a classic style, and the whole yacht is certified to commercial class, built for the extended offshore work that certification implies.

Layout and accommodation

Ten guests sleep in five cabins, including the full-beam master forward on the main deck. Seven crew have their own three cabins on the lower deck, along with the mess, while the captain's cabin sits on the upper deck next to the wheelhouse, close to where the watch is kept.

Performance and engineering

Twin 1,900 hp Caterpillar C32 engines give her a 10-knot cruise and a 13-knot top speed: figures built for a genuine ocean passage rather than a day out. A tender davit on the upper deck is sized to carry a substantial tender, and Quantum zero-speed stabilisers hold her steady once she stops, keeping remote anchorages comfortable rather than just reachable.

On deck and at anchor

A jacuzzi on deck sits close to the swimming platform, with sunpads for the hours in between, and air conditioning keeps the interior comfortable wherever she cruises.

Where she lies and how to see her

Seven Seas lies in Tuzla, Turkey. Boatcrowd sets up the viewing and is there with you for it, and once an offer is accepted, survey and sea trial follow before she changes hands.
