The operating base for the expedition is on a boat. But the boat is a river ferry, not a sea-going vessel. And Bhutan has four major river systems: the Drangme Chhu; the Puna Tsang Chhu, also called the Sankosh; the Wang Chhu; and the Amo Chhu. However, the vessel is not only a significantly larger ship than the modest sized ferry boats used on the rivers of Bhutan, but it is unlikely that any of the waterways in Bhutan could accommodate the vessel shown. The fittings visible on the ship make it clear that it is equipped for deep water operations (oceans or very large lakes).
