Rule 25

(a) In a narrow channel every power-driven vessel when proceeding along the course of the channel shall, when it is safe and practicable, keep to that side of the fairway or mid-channel which lies on the starboard side of such vessel.

(b) Whenever a power-driven vessel is nearing a bend in a channel where a power-driven vessel approaching from the other direction cannot be seen, such vessel, when she shall have arrived within one-half mile of the bend, shall give a signal by one prolonged blast of her whistle, which signal shall be answered by a similar blast given by any approaching power-driven vessel that may be within hearing around the bend. Regardless of whether an approaching vessel on the farther side of the bend is heard, such bend shall be rounded with alertness and caution.

Rule 26

All vessels not engaged in fishing shall, when under way, keep out of the way of any vessels fishing with nets or lines or trawls. This Rule shall not give to any vessel engaged in fishing the right of obstructing a fairway used by vessels other than fishing vessels.

Rule 27

In obeying and construing these Rules due regard shall be had to all dangers of navigation and collision, and to any special circumstances, including the limitations of the craft involved, which may render a departure from the above Rules necessary in order to avoid immediate danger.

PART D.-MISCELLANEOUS

Rule 28

(a) When vessels are in sight of one another, a power-driven vessel under way, in taking any course authorised or required by these Rules, shall indicate that course by the following signals on her whistle, namely:

One short blast to mean “I am altering my course to starboard."
Two short blasts to mean "I am altering my course to port."
Three short blasts to mean My engines are going astern."

66

(b) Whenever a power-driven vessel which, under these Rules, is to keep her course and speed, is in sight of another vessel and is in doubt whether sufficient action is being taken by the other vessel to avert collision, she may indicate such doubt by giving at least five short and rapid blasts on the whistle. The giving of such a signal shall not relieve a vessel of her obligations under Rules 27 and 29 or any other Rule, or of her duty to indicate any action taken under these Rules by giving the appropriate sound signals laid down in this Rule.

(c) Nothing in these Rules shall interfere with the operation of any special rules made by the Government of any nation with respect to the use of additional whistle signals between ships of war or vessels sailing under convoy.

Rule 29

Nothing in these Rules shall exonerate any vessel, or the owner, 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.

Rule 30

Reservation of Rules for Harbours and Inland Navigation

Nothing in these Rules shall interfere with the operation of a special rule duly made by local authority relative to the navigation of any harbour, river, lake, or inland water, including a reserved seaplane area.

Rule 31

Distress Signals

When a vessel or seaplane on the water is in distress and requires assistance from other vessels or from the shore, the following shall be the signals to be used or displayed by her, either together or separately, namely:

(a) A gun or other explosive signal fired at intervals of about a minute.

(b) A continuous sounding with any fog-signal apparatus.

(c) Rockets or shells, throwing red stars fired one at a time at short intervals.

(d) A signal made by radiotelegraphy or by any other signalling method consisting of the group in the Morse Code.

(e) A signal sent by radiotelephony consisting of the spoken word Mayday."

66

(f) The International Code Signal of distress indicated by N.C.

(g) A signal consisting of a square flag having above or below it a ball or anything resembling a ball.

(h) Flames on the vessel (as from a burning tar barrel, oil barrel, &c.).

(i) A rocket parachute flare showing a red light.

The use of any of the above signals, except for the purpose of indicating that a vessel or a seaplane is in distress, and the use of any signals which may be confused with any of the above signals, is prohibited.

Note. A radio signal has been provided for use by vessels in distress for the purpose of actuating the auto-alarms of other vessels and thus securing attention to distress calls or messages. The signal consists of a series of twelve dashes, sent in 1 minute, the duration of each dash being 4 seconds, and the duration of the interval between two consecutive dashes 1 second.

66

Rule 32

All orders to helmsmen shall be given in the following sense: right rudder or starboard to mean put the vessel's rudder to starboard"; left rudder or port to mean 'put the vessel's rudder to port."

RESOLUTIONS

Resolution 1

Carriage of Passengers in Excess of Convention Limits

The International Conference on Safety of Life at Sea, 1948,

RECOGNISING

That as a consequence of the situation created by the Second World War the number of passengers needing to be carried by sea at the present time is still considerably greater than the passenger accommodation available, and that a number of Governments signatory to the International Convention for the Safety of Life at Sea, 1929, have accordingly been obliged to allow passengers to be carried in their ships in excess of the limits allowed by that Convention,

RESOLVES

That Governments should each bring their practice into conformity with the provisions of the said Convention as soon as practicable, and in any event not later than the 31st day of December, 1950.

Resolution 2

Spain

In view of the Resolution of the General Assembly of the United Nations dated 12th December, 1946, the Conference considers that Spain is, for the present, prevented from becoming a party to the International Convention for the Safety of Life at Sea, 1948.

The Conference, however, agrees that Spain may, as soon as the Resolution of the General Assembly of the United Nations shall be abrogated or shall cease to be applicable, become a party to the International Convention for the Safety of Life at Sea, 1948, in accordance with Article X of the said Convention.

(187)

RECOMMENDATIONS

Throughout the following Recommendations "the present Convention " means the International Convention for the Safety of Life at Sea, 1948.

1. Denunciation of the International Convention for the Safety of Life at Sea, 1929

[merged small][ocr errors]

That Governments should accept the present Convention at as early a date as possible, and

That the Governments which become parties to the present Convention should denounce the International Convention for the Safety of Life at Sea, 1929, and should co-operate with one another with a view to ensuring that their respective denunciations become effective on dates as near as possible to, but not sooner than, the date on which the present Convention comes into force in respect of the Governments which have denounced the Convention of 1929.

2. Special Application of Convention Standards

The Conference, having excluded cargo ships of less than 500 tons gross tonnage and fishing vessels from the scope of particular provisions of the present Convention in recognition that the Convention requirements in question might not be applicable to such ships without modification, recommends that Governments should apply the principles of the present Convention to all such ships belonging to their countries as far as is reasonable and practicable.

The Conference, recognising that the safety of life at sea will be promoted by the fullest possible availability of radio on ships, recommends that all Governments should consider the possibility of extending with such modifications as may be necessary the requirements for radio installations so that such installations should, in so far as practicable, be carried by ships, including coasting ships and fishing vessels, not covered by the present Convention, on voyages in the open sea.

The Conference further recommends that Governments should take steps to ensure that, when ports in their countries are used by ships belonging to countries whose Governments are not parties to the present Convention, such ships are required to conform to standards not lower than those prescribed by the present Convention.

3. Amendments of the Convention Provisions Relating to Construction WHEREAS

The Conference has made provision for such amendments to the Regulations annexed to the present Convention as may prove necessary or desirable, but it is the opinion of the Conference that new developments in the art of shipbuilding or in the materials available for ship construction should not call for amendment of the Regulations until their worth has been proved.

The Conference therefore

RECOMMENDS

That Governments or the Intergovernmental Maritime Consultative Organisation in applying the provisions of Article IX, which gives them discretion as to the time of the application of amended Regulations governing construction, should take the above factor into consideration.

4. Standards of Watertight Subdivision of Passenger Ships

The Conference has given careful consideration to the question of the watertight subdivision of passenger ships in the light of the results achieved since the International Convention for the Safety of Life at Sea, 1929, came into force, and has agreed on certain additional requirements calculated to secure greater safety. It recognises, however, that the question of watertight subdivision deserves continued study, including in particular the operation of the Criterion of Service formula by which the factors of subdivision applicable to ships are determined.

The Conference therefore recommends Administrations to continue the study of this subject and to interchange the results of their study from time to time though the Authority charged with the circulation of information on matters within the scope of the present Convention.

5. Intact Stability

The Conference has considered the necessity for and the practicability of adopting Regulations for intact stability. Inasmuch as the rules which have been adopted for damage stability will affect intact stability, the Conference is of the opinion that additional experience should be gained to determine the extent to which any additional Regulations dealing with intact stability are required, before promulgating such rules.

The Conference recommends, however, that a further study be made by Governments of the subject of intact stability and that information on this subject be exchanged between Governments.

6. Openings in Bulkheads and Shell Plating

The Conference recognises the objection which attaches to openings, which may sometimes be open at sea, in the shell plating of ships and in the main transverse watertight bulkheads, but the Conference does not consider that it is practicable to adopt international regulations concerning such openings which are more exacting than those incorporated in the present Convention.

The Conference recommends, however, that the various Governments make special efforts to ensure that the number of such openings, particularly hinged sidescuttles below the margin line and doors low down in the machinery space bulkheads, be kept at the minimum required in each case.

7. Metal Hatchway Covers

The Conference has considered the use of metal hatchway covers on weather decks.

The Conference recommends Governments to exchange information regarding their experience as to the respective efficacy of metal and wood hatchway covers for preventing the spread of fire and other matters within the scope of the present Convention.
