RMK Marine has operated as a leading force in Turkish shipbuilding for over 50 years, starting as a small workshop in Istanbul's Haliç before growing into a globally recognized superyacht builder. Since 1997, the yard has been a key subsidiary of the Koç Group, Turkey’s largest industrial conglomerate, which provides the financial stability and industrial resources required for ambitious custom projects. This unique positioning allows the shipyard to apply rigorous military-grade engineering standards to the construction of luxury motor and sailing yachts.

Operating from a state-of-the-art 30-acre facility in Tuzla, the yard specializes in bespoke projects constructed from steel, aluminum, and advanced composites. Their capability spans a wide spectrum, from pocket-sized explorers like the 120’11” (36.9m) Seven Seas to expansive transoceanic vessels exceeding 230’ (70m). The shipyard’s infrastructure includes climate-controlled hangars and specialized workshops that ensure every phase of production, from interior joinery to technical outfitting, is managed in-house for absolute quality control.

The builder's reputation is anchored in successful collaborations with elite international design firms, resulting in a portfolio of award-winning yachts that balance rugged capability with Mediterranean elegance. Owners choose this yard for its technical transparency, engineering pedigree, and the security of building with an established industrial giant. Whether commissioning a high-performance sailing yacht or a long-range explorer, clients find a partner dedicated to delivering precision-engineered vessels that perform reliably across the seven seas.
