(_b_) Green and red side lights constructed and fixed as prescribed
in article 2 (_b_) and (_c_) and of such a character as to be
visible at a distance of at least 1 mile, or a combined lantern showing
a green light and a red light from right ahead to 2 points abaft the
beam on their respective sides. Such lanterns shall be carried not less
than 3 feet below the white light.

Second. Small steamboats, such as are carried by seagoing vessels, may
carry the white light at a less height than 9 feet above the gunwale,
but it shall be carried above the combined lantern mentioned in
subdivision 1 (_b_).

Third. Vessels under oars or sails of leas than 20 tons shall have ready
at hand a lantern with a green glass on one side and a red glass on the
other, which on the approach of or to other vessels shall be exhibited,
in sufficient time to prevent collision, so that the green light shall
not be seen on the port side nor the red light on the starboard side.

The vessels referred to in this article shall not be obliged to carry
the lights prescribed by article 4 (_a_) and article 11 last
paragraph.

ART. 8. Pilot vessels when engaged on their station on pilotage duty
shall not show the lights required for other vessels, but shall carry a
white light at the masthead, visible all around the horizon, and shall
also exhibit a flare-up light or flare-up lights at short intervals,
which shall never exceed fifteen minutes.

On the near approach of or to other vessels they shall have their side
lights lighted ready for use and shall flash or show them at short
intervals to indicate the direction in which they are heading; but the
green light shall not be shown on the port side nor the red light on the
starboard side.

A pilot vessel of such a class as to be obliged to go alongside of a
vessel to put a pilot on board may show the white light instead of
carrying it at the masthead, and may instead of the colored lights above
mentioned have at hand ready for use a lantern with a green glass on the
one side and a red glass on the other, to be used as prescribed above.

Pilot vessels when not engaged on their station on pilotage duty shall
carry lights similar to those of other vessels of their tonnage.

ART. 9. Fishing vessels and fishing boats when under way and when not
required by this article to carry or show the lights therein named shall
carry
