In principle, our eCopters can be used wherever a high level of effort is required to transport goods or people from A to B. The range extends from supplying sailors on container ships, which often do not go ashore at all, to remote alpine huts to bridging a traffic bottleneck like the Bosporus in Istanbul. Instead of laboriously circumnavigating e.g. Lake Constance, drones can fly directly from one shore to the other. The same applies to cities on rivers and by the sea.
