Neglect to carry Lights or Signals, or of any Neglect to keep a proper Look-out, or of the Neglect of any Precaution which may be required by the ordinary Practice of Seamen, or by the special Circumstances of the Case.

Whereas there has been doubt or misapprehension concerning the effect of the said two articles:

And whereas the Admiralty and the Board of Trade have jointly recommended to her majesty to make the following additions to the said regulations for the purpose of explaining the said recited articles, and of removing the said doubt and misapprehension :

Now, therefore, Her Majesty, by virtue of the powers vested in Her by the said recited Act, and by and with the advice of Her Privy Council, is pleased to make the following additions to the said regulations by way of explanation of the said two recited articles; that is

to say,

The said two articles, numbered 11 and 13 respectively, only apply to cases where ships are meeting end on or nearly end on in such a manner as to involve risk of collision. They consequently do not apply to two ships which must, if both keep on their respective courses, pass clear of each other.

The only cases in which the said two articles apply are when each of the two ships is end on or nearly end on to the other; in other words, to cases in which by day each ship sees the masts of the other in a line or nearly in a line with her own; and by night to cases in which each ship is in such a position as to see both the side lights of the other.

The said two articles do not apply by day to cases in which a ship sees another ahead crossing her own course; or by night to cases where the red light of one ship is opposed to the red light of the other; or where the green light of one ship is opposed to the green light of the other; or where a red light without a green light, or a green light without a red light, is seen ahead; or where both green and red lights are seen anywhere but ahead,

LIGHTS

TO ILLUSTRATE THE USE OF THE
CARRIED BY VESSELS AT SEA,

And the manner in which they indicate to the vessels which sees them, the position and description of the vessel that carries them.

WHEN BOTH GREEN AND RED LIGHTS ARE SEEN.

A sees a Red and Green Light ahead:-A knows that a vessel is approaching her on a course directly opposite to her own, as B. (Fig. 1.)

If A sees a White Mast-head Light above the other two, she knows that B is a steam vessel.

WHEN THE RED AND NOT THE GREEN LIGHT IS SEEN.

A sees a Red Light ahead or on the bow;-A knows that either (Fig. 2) a vessel is approaching her on her Port bow, as B; or (Fig. 3) a vessel is crossing in some direction to Port, as DDD.

If A sees a White Mast-head Light above the Red Light, A knows that the vessel is a steam vessel, and is either approaching her in the same direction, as B, or is crossing to Port in some direction, as DDD.

WHEN THE GREEN AND NOT THE RED LIGHT IS SEEN.

A sees a Green Light ahead or on the bow;-A knows that either (Fig. 4) a vessel is approaching her on her Starboard bow, as B, or (Fig. 5) a vessel is crossing in some direction to Starboard, as DDD.

If A sees a White Mast-head Light above the Green Light, A knows that the vessel is a steam vessel, and is either approaching her in the same direction, as B, or is crossing to starboard in some direction, as DDD,

What light or lights are required by the regulations to be exhibited by steam ships in a roadstead or fairway at anchor.

A.-The same as for sailing vessels.

3.-Where is the anchor light to be exhibited?

A.-It may be exhibited at a height of 20 feet above the deck, but not higher.

5.-What is the description of the lantern containing the anchor light required by the regulations?

8. What is the number of lights required by the regulations to be carried by sailing ships when under weigh at night?

A.-Two.

9.-Of what colour are these lights, and how are they to be placed on on board the ship?

A. A green light on the starboard side, and a red light on the port side.

10. What description of light must be shown from the sides of sailing vessels under weigh; and over how many points of the compass, and in what directions, and how far, are they required to show?

A.-Each light must be so constructed as to show an uniform and unbroken light over an arc of the horizon of 10 points of the compass; so fixed as to throw the light from right ahead to two points abaft the beam on the starboard and port sides respectively; and of such a character as to be visible on a dark night, with a clear atmosphere, at a distance of at least two miles.
