When each has the wind on a different side, the vessel that has the wind on the port side shall keep out of the way of the other. This is commonly known as the starboard rule. ii. When both vessels have the wind on the same side, the vessel that is to windward shall keep out of the way of the vessel that is to leeward. That is the boat closest to the wind keeps out of the way of the other. iii. If a vessel with the wind on the port side sees a vessel to windward and cannot determine with certainty whether the other vessel has the wind on the port or the starboard side, it shall keep out of the way of the other. For the purpose of this Rule, the windward side shall be deemed to be the side opposite to that on which the mainsail is carried. 132 Appendices_fn_Layout 1 17/10/2017 17:05 Page 133 1 Head-on Situations – Rule 14 Rules 16 and 17 concern actions Appendices (a) When two power-driven by give-way and stand-on vessels are meeting on vessels respectively.

(c) When a vessel is in any doubt as to whether such a situation exists, it shall assume that it Navigation Lights does exist and act accordingly. Navigation lights must be displayed on boats operating between sunset Note: For sailing vessels, see Rule and sunrise and must also be used 12. in daylight hours during periods of restricted visibility. The types of light required are determined by the boat type and their activity. They indicate the length of boat, the direction of travel or if they are anchored. Rule 20 of the Collision Crossing Situations – Rule 15 Regulations requires that lights When two power-driven vessels are prescribed shall, if carried, be crossing and at risk of collision, the exhibited from sunset to sunrise vessel that has the other on its and from sunrise to sunset in starboard side shall keep out of the restricted visibility, and may be way and shall, if circumstances exhibited in all other circumstances permit, avoid crossing ahead of the when it is deemed necessary. other vessel. 133 Appendices_fn_Layout 1 17/10/2017 17:05 Page 134 1 Rule 21 provides definitions of different lights. Rule 22 provides for lights to be visible at minimum ranges on a dark night with a clear atmosphere. These are summarised in the Appendices following Table. Table – Visibility of Vessel Lights Minimum light visibility (nm) for vessel length (m) (White, red, yellow, green). 50 m and Between 12 m Less than 12 m greater and 50 m Masthead 6 nm 5 nm* 2 nm Sidelight 3 nm 2 nm 1 nm Stern light 3 nm 2 nm 2 nm Towing light 3 nm 2 nm 2 nm All round light 3 nm 2 nm 2 nm *Where the length of the ship is 12 m or greater, but less than 20 m, the masthead light visibility is 3 nm. 134 Appendices_fn_Layout 1 17/10/2017 17:05 Page 135 1 Light Combinations Appendices The term “under way” in relation to a vessel is used to describe a vessel that is not at anchor or made fast to the shore or aground.
