The picture shows how one of the pumps hangs directly under the propeller and rudder. Pumps use electricity. While the Generator is an option we find out that the harbor is used by hotel barges during summer. We find the owners and they give us permission to connect to their electrical box. The connection box was unfortunately at the other end of the harbor and it was 3 phase, 380V, but with the right connecting plugs and 150 m of 3x-2.5mm rubber cable we were also able to solve that problem.
