2. The International Code signal of distress indicated

4. A continuous sounding with any fog-signal apparatus.
At night—
<poem> 1. A gun or other explosive signal fired at intervals of about a minute.
2. Flames on the vessel (as from a burning tar-barrel, oil-barrel, etc.).
3. Rockets or shells, throwing stars of any colour or description, fired one at a time, at short intervals.

The skipper of the small yacht will discover,
from a perusal of these regulations, that it is his duty
to carry with him the following lanterns—a white
riding light, a red port light, a green starboard light,
and a white bull's-eye lantern; for he will find the
bull's-eye the most convenient form of light to show
from the stern when overtaken by a vessel (see Art.
10). The author on his cruising yachts invariably
kept a lit bull's-eye lantern hanging at the top of
the companion lantern at night, within easy reach
of the man at the helm.
A vessel under 20 tons need not carry two sidelights, as she is permitted by Article 7 to carry a lantern with a green glass on one side and a red glass on the other, to be exhibited on the approach of a vessel. A lantern is also sold which combines in itself the port, starboard, and riding lights.
