9. (1) Subject to subsection (3), every ship described in Column I of an item of the schedule, other than a dredge or floating plant, and maintaining a listening watch pursuant to section 8 shall make a navigation safety call on the channel set out in Column III of that item

• (a) when risk of collision with another ship is deemed to exist under those provisions of the Collision Regulations that apply in the area being navigated by the ship;

• (b) when the navigation safety call of another ship indicates that a close quarters situation may develop;

• (c) when the ship is in a narrow channel or fairway and is about to

  • (i) overtake another ship,

  • (ii) be overtaken by another ship and agrees or objects to being overtaken;

• (d) when doubt exists as to the actions or the intentions of another ship;

• (e) when the ship is nearing a bend in a river, channel or fairway or an obstruction around which an approaching ship cannot adequately be seen;

• (f) when the ship is approaching, in restricted visibility,

  • (i) a charted route, including a ferry route, or

  • (ii) a concentration of vessels;

• (g) before the ship commences a manoeuvre that will impede the safe navigation of other ships;

• (h) when a ship is engaged in fishing with nets, lines, trawls, trolling lines or other apparatus, or restricted in its ability to manoeuvre in or near a routing system and is being approached by another ship, other than a ship engaged in fishing;

• (i) when the ship is approaching a dredge or floating plant in or near a river, channel or fairway;

• (j) 15 minutes before and again immediately before the ship departs from any berth, anchorage, mooring area, booming ground, dredge or floating plant; and

• (k) at any other time when a navigation safety call may contribute to the safe navigation of the ship or any other ship.

(2) A navigation safety call referred to in subsection (1) shall

• (a) contain only information that is essential for safe navigation and not exceed one minute in duration;

• (b) so far as is practicable, indicate, in the following sequence,

  • (i) the identity of the ship,

  • (ii) the location of the ship, and

  • (iii) the intended course of action; and

• (c) be followed, if necessary, in the following sequence, by indications as to

  • (i) the present course and speed of the ship, and

  • (ii) whether the ship is

    • (A) towing or pushing,

    • (B) not under command,

    • (C) restricted in its ability to manoeuvre,

    • (D) engaged in fishing, other than trolling,

    • (E) severely restricted in its ability to deviate from the course it is following because of its draft in relation to the available depth of water,

    • (F) engaged in pilotage duty,

    • (G) at anchor, or

    • (H) aground.

(3) A navigation safety call referred to in subsection (1) is not required to be made by a ship

• (a) that, while engaged in a towing operation, is manoeuvring in or around any berth, anchorage, mooring area, booming ground, dredge or floating plant if the ship

  • (i) manoeuvres in such a manner that it will not impede the safe navigation of other vessels, and

  • (ii) makes a navigation safety call 15 minutes before its final departure from such berth, anchorage, mooring area, booming ground, dredge or floating plant, or

• (b) that is reporting to a traffic centre

unless any of the circumstances described in paragraphs (1)(a) to (h) or (k) occurs.

(4) Subject to subsection (5), navigation safety calls within the Great Lakes Basin on Channel 13 shall be limited to a transmission power of one watt or less.

(5) A transmission power of calls referred to in subsection (4) that is greater than one watt, but not greater than 25 watts, may be used in the case of

• (a) an emergency;

• (b) a failure on the part of the vessel being called to respond to a second call at a transmission power of one watt or less; or

• (c) a broadcast in blind situations such as where the vessel is rounding a bend in a channel.
