ll not be obliged to carry
the colored side lights; but every such boat and vessel shall in lieu
thereof have ready at hand a lantern with a green glass on the one
side and a red glass on the other side, and on approaching to or being
approached by another vessel such lantern 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 following portion of this article applies only to fishing vessels
and boats when in the sea off the coast of Europe lying north of Cape
Finisterre:

(_a_) All fishing vessels and fishing boats of 20 tons net
registered tonnage or upward when under way and when not having their
nets, trawls, dredges, or lines in the water shall carry and show the
same lights as other vessels under way.

(_b_) All vessels when engaged in fishing with drift nets shall
exhibit two white lights from any part of the vessel where they can be
best seen. Such lights shall be placed so that the vertical distance
between them shall be not less than 6 feet and not more than 10 feet and
so that the horizontal distance between them measured in a line with the
keel of the vessel shall be not less than 5 feet and not more than 10
feet. The lower of these two lights shall be the more forward, and both
of them shall be of such a character and contained in lanterns of such
construction as to show all round the horizon on a dark night with a
clear atmosphere for a distance of not less than 3 miles.

(_c_) All vessels when trawling, dredging, or fishing with any kind
of dragnets shall exhibit from some part of the vessel where they can be
best seen two lights. One of these lights shall be red and the other
shall be white. The red light shall be above the white light and shall
be at a vertical distance from it of not less than 6 feet and not more
than 12 feet, and the horizontal distance between them, if any, shall
not be more than 10 feet. These two lights shall be of such a character
and contained in lanterns of such construction as to be visible all
round the horizon on a dark night with a clear atmosphere, the white
light to a distance of not less than 3 miles and the red light of not
less than 2 miles.

(_d_) A vessel employed in line fishing with her lines out shall
carry the same lights as a vessel when engaged in fishing with drift
nets.
