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 at anchor, respectively. (See article 15 (d), (e), and last paragraph.)
(g) In fog, mist, falling snow, or heavy rain storms drift-net vessels attached to their nets, and vessels when trawling, dredging, or fishing with any kind of dragnet, and vessels line fishing with their lines out shall, if of 20 tons gross tonnage or upward, respectively, at intervals of not more than one minute make a blast—if steam vessels, with the whistle or siren, and if sailing vessels, with the fog horn—each blast to be followed by ringing the bell.
(h) Sailing vessels or boats fishing with nets or lines or trawls when under way shall in daytime indicate their occupation to an approaching vessel by displaying a basket or other efficient signal where it can best be seen.
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.
