water, fuel oil, and ammunition, are to be sent to certain
stations. When the marker box is flagged correctly,
there will be little chance of receiving the wrong cargo
at a station.
The Boatswain's Mates will usually test the station
marker box prior to underway replenishment, but you
should be prepared for any possible trouble and have
spare light bulbs readily available.
Hull Contour Lights
The HULL CONTOUR LIGHTS (blue) are found
on replenishment-at-sea delivery ships. These lights
assist the receiving ship coming alongside during
replenishment operations by establishing the delivery
ship's contour lines. Two or three hull contour (blue)
signal lights (135arc) are located on each side of the
delivery ship (fig. 4-25) at the railing. Additional lights
may be installed if obstructions exist beyond the
delivery ship's parallel contour lines.
