HARBOUR TUG BOAT BY REVELL
When cargo vessels come into harbour having covered thousands of sea miles there is still a difficult section ahead of them. This is where the harbor tugboats come into play, taking command and pulling the huge ships safely to the pier. The tugboats do not take on cargo, but are used to haul and maneuver large tankers and cargo ships. The small, robust, but very maneuverable ships have a very powerful engine from 250 to several thousand horsepower.
