In restricted visibility, the first light you see could be the stern light of a 1000 foot tanker making a wide turn to starboard. Since you''ve determined that it''s a white light and you don''t see the running
lights, it''s heading away from you, so, no worries, eh? Of course it''s up so high (how high up is it, anyway?) it could be a masthead range light (they''re white too, aren''t they?) So you stick you head below to check Chapman''s to be sure, as their stern swings sideways into you. Please take a bearing, repeatdely, regardless of what color the light is.
