第 十 九 條    Rule 19

船舶在能見度不良時的行動規(guī)則  

Conduct of Vessels in Restricted Visibility

1．本條適用于在能見度不良的水域中或在其附近航行時不在互見中的船舶。

(a) This Rule applies to vessels not in sight of one another when navigating in or near an area of restricted visibility.

2．每一船應以適合當時能見度不良的環(huán)境和情況的安全航速行駛，機動船應將機器作好隨時操縱的準備。

(b) Every vessel shall proceed at a safe speed adapted to the prevailing circumstances and conditions of restricted visibility. A power-driven vessel shall have her engines ready for immediate maneuver.

3．在遵守本章第一節(jié)各條時，每一船應充分考慮當時能見度不良的環(huán)境和情況。

(c) Every vessel shall  have due  regard to the prevailing circumstances and conditions of restricted visibility when complying with the Rules of Section I of this Part.

4．一船僅憑雷達測到他船時，應判定是否正在形成緊迫局面和（或）存在碰撞危險。若是如此，應及早地采取避讓行動，如果這種行動包括轉向，則應盡可能避免如下各點：

(d) A vessel which detects by radar alone the presence of another vessel shall determine if a close-quarters situation is developing and/or risk of collision exists. If so, she shall take avoiding action in ample time, provided that when such action consists of an alteration of course, so far as possible the following shall be avoided:

   （1）除對被追越船外，對正橫前的船舶采取向左轉向；

(i) an alteration of course to port for a vessel forward of the beam, other than for a vessel being overtaken;

   （2）對正橫或正橫后的船舶采取朝著它轉向。

(ii) an alteration of course towards a vessel abeam or abaft the beam.

5．除已斷定不存在碰撞危險外，每一船當聽到他船的霧號顯似在本船正橫以前，或者與正橫以前的他船不能避免緊迫局面時，應將航速減到能維持其航向的最小速度。必要時，應把船完全停住，而且，無論如何，應極其謹慎地駕駛，直到碰撞危險過去為止。

(e) Except where it has been determined that a risk of collision does not exist, every vessel which hears apparently forward of her beam the fog signal of another vessel, or which cannot avoid a

close-quarters situation with another vessel forward of her beam, shall reduce her speed to the minimum at which she can be kept on her course. She shall if necessary take all her way off and in any event navigate with extreme caution until danger of collision is over.
