Rules of the Road: BOTH INTERNATIONAL & INLAND Which vessel may show identifying lights when not ac...

Tiatia81, this is asking if any of the listed occupational vessels can display their unique ID lights (fishing = red over white, Pilot = white over red, mine sweeping = three green) when they are "off duty" or not working. The associated RULES are 26 (fishing), 27 (mine clearance), and 29 (pilot duty). In each RULE the wording states "when engaged in...", clearly implying that they must be on-duty to show the ID lights. RULE 29 goes one step further and actually states that off duty pilot vessels must show only lights associated with underway power vessels (no white over red)/

thanks Golivi, that helped
