The trawl skippers operate wetfish trawlers with a loading capacity of 60 to 80 tonnes of fresh fish packed on ice. Vessels range between 28 and 48 m in length and measure 268 to 838 GRT (Benguela Current Large Marine Ecosystem 2006). Trips are up to 8 days long. Trawling involves dragging a net behind the vessel across the seabed.
