Servant
The servant is a concept from sailing ships. This is about 120 cm long and more than 20 cm strong square wood, which is vertically fixed on the side of a sailing ship. In the process, it is mostly led through the deck slides into the underlying deck. It is used for passing through and covering traps or pods. For this purpose he has a disc hopper and a document head. In the case of single- and two-mast ships, the servant is generally horizontal and usually has two disciplines. Edit source source text
