HOW IS SHE HEADING?

Diagram 3 represents a steamship heading North with the wind
from South, right aft. Discuss the respeptive lights of the sailing vessels
on the bearings as indicated, how the vessels may be heading, how they
are carrying the wind and what action the steamship should take if
there were risk of collision.
I 1. The wind being from South the prohibited courses for a sailing
vessel lie between E.S.E. and W.S.W., that is 6 points on each side
of the wind.
The green light ahead indicates a sailing vessel heading between
E.N.E. and E.S.E. She cannot lie closer to the wind than 6 points, via.,
E.S.E. She may be close-hauled to starboard, or she may have the
wind a little abaft her beam depending on how she is heading.
The red light ahead indicates a vessel heading between W.N.W. and
W.S.W. She may be close-hauled to port, or slightly free with the
wind a little afeaft her port beam.
2. The red light 4 points on my starboard bow indicates a sailing
vessel heading between W.S.W. and N.N.W. She is either close-hauled
to port, or free to port.
^3. The red light on my starboard beam indicates a vessel heading
between West and N.N.W., she is free to port.
4. The green light 4 points on my port bow indicates a vessel heading
between E.S.E. and N.N.E., she cannot He closer to the wind than E.S.E.
She is either close-hauled to starboard, or free to starboard.
5. The green light on my port beam is that of a sailing vessel heading
between East and N.N.W., free to starboard.
If the lights keep on the same bearing there is risk of collision,
I would give 1 blast and alter course to starboard and pass under
the stern of the red lights on my starboard bow, and for the green lights
on my port bow I would alter course to port and give 2 blasts. ^
