starboard and port sides, respectively, and not less than 6 nor more
than 12 feet below the tricolored lantern, a white light in a lantern so
constructed as to show a clear, uniform, and unbroken light all around
the horizon.

Second. If sailing vessels of 7 tons gross tonnage and upward, shall
carry a white light in a lantern so constructed as to show a clear,
uniform, and unbroken light all around the horizon, and shall also be
provided with a sufficient supply of red pyrotechnic lights, which shall
each burn for at least 30 seconds, and shall be shown on the approach of
or to other vessels in sufficient time to prevent collision.

In the Mediterranean Sea the vessels referred to in subdivision
(_b_) 2 may use a flare-up light in lieu of a pyrotechnic light.

All lights mentioned in subdivision (_b_) 1 and 2 shall be visible
at a distance of at least 2 miles.

Third. If sailing vessels of less than 7 tons gross tonnage, shall not
be obliged to carry the white light mentioned in subdivision (_b_)
2 of this article, but if they do not carry such light they shall have
at hand, ready for use, a lantern showing a bright white light, which
shall on the approach of or to other vessels be exhibited where it can
best be seen, in sufficient time to prevent collision; and they shall
also show a red pyrotechnic light, as prescribed in subdivision
(_b_) 2, or in lieu thereof a flare-up light.

(_c_) Vessels and boats when line fishing with their lines out and
attached to their lines, and when not at anchor or stationary, shall
carry the same lights as vessels fishing with drift nets.

(_d_) Fishing vessels and fishing boats may at any time use a
flare-up light in addition to the lights which they are by this article
required to carry and show. All flare-up lights exhibited by a vessel
when trawling or fishing with any kind of dragnet shall be shown at the
after part of the vessel, excepting that if the vessel is hanging by the
stern to her fishing gear they shall be exhibited from the bow.

(_e_) Every fishing vessel and every boat when at anchor shall
exhibit a white light visible all around the horizon at a distance of at
least 1 mile.

(_f_) If a vessel or boat when fishing becomes stationary in
consequence of her gear getting fast to a rock or other obstruction, she
shall show the light and make the fog signal prescribed for a vessel
