Side 125 - ... points abaft the beam on the port side, and of such a character as to be visible at a distance of at least 2 miles.
Side 130 - On the near approach of or to other vessels they shall have their side lights lighted ready for use and shall flash or show them at short intervals to indicate the direction in which they are heading; but the green light shall not be shown on the port side nor the red light on the starboard side. A pilot vessel of such a class as to be obliged to go alongside of a...
Side 134 - Rule shall be used as follows — " (i) A power-driven vessel making way through the water shall sound at intervals of not more than 2 minutes a prolonged blast. " (ii) A power-driven vessel under way, but stopped and making no way through the water, shall sound at intervals of not more than 2 minutes two prolonged blasts, with an interval of about 1 second between them.
Side 138 - Every vessel which is directed by these Rules to keep out of the way of another vessel shall, if the circumstances of the case admit, avoid crossing ahead of the other.
Side 140 - I am altering my course to starboard." Two short blasts to mean "I am altering my course to port.
Side 135 - Risk of collision can, when circumstances permit, be ascertained by carefully watching the compass bearing of an approaching vessel. If the bearing does not appreciably change, such risk should be deemed to exist.
Side 129 - Small rowing boats, whether under oars or sail, shall only be required to have ready at hand an electric torch or a lighted lantern showing a white light, which shall be exhibited in sufficient time to prevent collision.
Side 135 - A vessel of less than 12 metres in length shall not be obliged to give the above-mentioned signals but, if she does not, shall make some other efficient sound signal at intervals of not more than 2 minutes.
Side 123 - Rules specifying the carrying of lights and shapes, these provisions shall be followed as closely as circumstances permit. (b) The Rules concerning lights shall be complied with in all weathers from sunset to sunrise, and during such times no other lights shall be exhibited, except such lights as cannot be mistaken for the prescribed lights or impair their visibility or distinctive character, or interfere with the keeping of a proper look-out. (c) In the following Rules, except where the context...
Side 126 - A vessel when towing, a vessel engaged in laying or in picking up a submarine cable or navigation mark, and a vessel under way which is unable to get out of the way of an approaching vessel through being not under command or unable to...
