The Nevelskoy Strait is a narrow waterway located in the Russian Far East, separating the islands of Sakhalin and the Kamchatka Peninsula. It connects the Sea of Okhotsk to the Pacific Ocean, playing a crucial role in maritime navigation in the region. The strait is named after the Russian explorer Gavriil Nevelskoy, who was instrumental in mapping the area in the 19th century. The strait is approximately 30 kilometers long and varies in width, with its narrowest point being around 6 kilometers. It is significant for shipping routes, allowing vessels to bypass longer journeys around the islands. The Nevelskoy Strait is also known for its challenging navigation conditions due to strong currents and varying depths.
