same Lights as Steam Ships under weigh, with the Exception of the White Mast-head Lights, which they shall never carry.
Art. 6. Whenever, as in the Case of small Vessels during bad Weather, the Green and Red Lights cannot be fixed, these Lights shall be kept on deck, on their respective Sides of the Vessel, ready for instant Exhibition; and shall, on the Approach of or to other Vessels, be exhibited on their respective Sides in sufficient Time to prevent Collision, in such manner as to make them most visible, and so that the Green Light shall not be seen on the Port Side, nor the Red Light on the Starboard Side.
To make the Use of these portable Lights more certain and easy, the Lanterns containing them shall each be painted Outside with the Colour of the Light they respectively contain, and shall be provided with suitable Screens.
Art. 7. Ships, whether Steam Ships or Sailing Ships, when at Anchor in Roadsteads or Fairways shall exhibit, where it can best be seen, but at a Height not exceeding Twenty Feet above the Hull, a White Light, in a globular Lantern of Eight Inches in Diameter, and so constructed as to show a clear uniform and unbroken Light visible all round the Horizon, and at a Distance of at least One Mile.
Art. 8. Sailing Pilot Vessels shall not carry the Lights required for other Sailing Vessels, but shall carry a White Light at the Mast-head, visible all round the Horizon,—and shall also exhibit a Flare-up Light every Fifteen Minutes.
Art. 9. Open Fishing Boats and other open Boats shall not be required to carry the Side Lights required for other Vessels; but shall, if they do not carry such Lights, carry a Lantern having a Green Slide on the one side and a Red Slide on the other Side; and on the Approach of or to other Vessels, 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.
Fishing Vessels and open Boats when at Anchor, or attached to their Nets and stationary, shall exhibit a bright White Light.
Fishing Vessels and open Boats shall, however, not be prevented from using a Flare-up in addition, if considered expedient.
Rules concerning Fog Signals.
Art. 10. Whenever there is Fog, whether by Day or Night, the Fog Signals described below shall be carried and used, and shall be sounded at least every Five Minutes; viz. :—
(a) Steam Ships under weigh shall use a Steam Whistle placed before the funnel, not less than eight feet from the deck:
(6) Sailing Ships under weigh shall use a Fog Horn:
(c) Steam Ships and Sailing Ships when not under weigh shall use a Bell.
Steering and Sailing Rules.
Art. 11. If Two Sailing Ships are meeting End on or nearly End on so as to involve Risk of Collision, the Helms of both shall be put to Port, so that each may pass on the Port Side of the other.
Art. 12. When Two Sailing Ship are crossing so as to involve Risk of Collision, then, if they have the Wind on different Sides, the Ship with the Wind on the Port Side shall keep out of the Way of the Ship with the Wind on the Starboard Side; except in the Case in which the Ship with the Wind on the Port Side is closed hauled and the other Ship free, in which Case the latter Ship shall keep out of the Way; but if they have the Wind on the same Side, or if One of them has the Wind aft, the Ship which is to windward shall keep out of the Way of the Ship which is to leeward.
Art. 13. If Two Ships under Steam are meeting End on or nearly End on so as to invole Risk of Collision, the Helms of both shall be put to Port, so that each may pass on the Port Side of the other.
Art. 14. If Two Ships under Steam are crossing so as to involve Risk of Collision, the Ship which has the other on her own Starboard Side shall keep out of the Way of the other.
Art. 15. If Two Ships, one of which is a Sailing Ship, and the other a Steam Ship, are proceeding in such Directions as to involve Risk of Collision, the Steam Ship shall keep out of the Way of the Sailing Ship.
Art. 16. Every Steam Ship, when approaching another Ship so as to involve Risk of Collision, shall slacken her Speed, or, if necessary, stop and reverse; and every Steam Ship shall, when in a Fog, go at a moderate speed.
Art. 17. Every Vessel overtaking any other Vessel shall keep out of the Way of the said last-mentioned Vessel.
Art. 18. Where by the above Rules One of Two Ships is to keep out of the Way, the other shall keep her Course, subject to the Qualifications contained in the following Article.
Art. 19. In obeying and construing these Rules, due regard must be had to all Dangers of Navigation; and due regard must also be had to any special Circumstances which may exist in any particular Case rendering a Departure from the above Rules necessary in order to avoid immediate Danger.
Art. 20. Nothing in these Rules shall exonerate any Ship, or the Owner, or Master, or Crew thereof, from the Consequences of any
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,
TO ILLUSTRATE THE USE OF THE LIGHTS 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.
