Specification of the size of panels (aluminum, plastic or steel) may vary and are listed under article 8. This Regulation applies to the territorial waters and economic zone north of 62 N, in the Skagerrak bordering to the west by a straight line through Lindesnes and Hanstholmen lighthouse and to the south by a straight line through the Skagen lighthouse and Tistlarna externally 4 nautical miles from the baseline in the fishery zone around Jan Mayen, the fishery protection zone around Svalbard and its territorial waters.
