a fishing vessel designed for trawling, in which the nets are hauled in over the stern, up a ramp or over a roller or the bulwark, with the aid of a derrick or gantry
On stern trawlers with ramps, the upper part of the ramp must be fitted with a gate or other means of securing it of the same height as the bulwarks or other adjacent means, to protect workers from the risk of falling into the ramp.
