West İstanbul Marina

West İstanbul Marina sits on the Marmara Sea coast in Beylikdüzü, on Istanbul's western outskirts, and it's particularly well-regarded for its technical and maintenance capabilities — if your boat needs serious work done, this is the place. The setup here is professional and purposeful, with a full team geared toward yacht repair rather than just overnight stays. You'll find it at Yakuplu on the Marmara shoreline, roughly 35km west of central Istanbul, reachable at +90 212 850 22 00.
