“The Lun-class ekranoplan (NATO reporting name Duck) was a ground effect vehicle (GEV) designed by Rostislav Evgenievich Alexeev and used by the Soviet and Russian navies from 1987 until sometime in the late 1990s. It “flew” using the lift generated by the ground effect of its large wings when close to the surface of the water – about four metres or less. Although they might look similar and/or have related technical characteristics, ekranoplans like the Lun are not aircraft, seaplanes, hovercraft, or hydrofoils – ground effect is a separate technology altogether. The International Maritime Organization classifies these vehicles as maritime ships. The name Lun comes from the Russian for harrier”. – Wikipedia (Photo by Igor113)

“For centuries, the Moken sea nomads have traveled the islands between Thailand and Myanmar fishing and foraging for food on the sea floor. Throughout the Mergui Archipelago, Moken migrate in flotillas of Kabangs (traditional boat of the Moken people), stopping at different islands and beaches. Expert freedivers, the Moken have adapted physically to an aquatic life, developing unique characteristics that let them see better and hold their breath longer while underwater”. – Taylor Weidman.
