Definition
A vessel trawling shows two all-round lights in a vertical line, green over white; a vessel fishing other than trawling shows red over white. By day both display two cones with their apices together, and vessels of less than 20 metres may substitute a basket. Sidelights and a sternlight are added only when making way. Where gear extends more than 150 metres horizontally, an all-round white light or a cone apex upwards marks that direction.
