Tail lift
The Heckaufschleppe , colloquially rear train called is that the rear and slightly below the water line cut into the hull path that forward and leading up to the fishing deck. A stern drag for stern trawlers and whaling ships is typical .
In the case of tail catchers, the tail lift is used to launch and retrieve the trawl net. The rear lift enables the most extensive mechanization of the launching and retrieving process of the codend. On whaling ships the stern lift is used to pull the hunted large whales on board .
A stern drag typically takes up about half the width of the ship at the blunt, vertical stern and is spanned by arches with crane winches. It can be locked at the stern with rotating plates to prevent waves from breaking in and / or at the convexly curved transition to the approximately horizontal catching deck, which can be pivoted upwards and which at the same time exposes a grate through which the (small) fish of the catch can fall down for further processing.
Rear towing was first used on whaling ships in the 1920s, and the development of the fishing vessel into a stern catcher with stern towing began shortly after the end of the Second World War with the British ships Oriana and Fairfree .
