In determining a safe speed the following factors shall be among those taken into account:１．对所有船舶：(a) By all vessels: （１）能见度情况；(i) the state of visibility; （２）通航密度，包括渔船或者任何其他船舶的密集程度；(ii) the traffic density including concentrations of fishing vessels or any other vessels;（３）船舶的操纵性能，特别是在当时情况下的冲程和旋回性能；(iii) the manoeuvrability of the vessel with special reference to stopping distance and turning ability in the prevailing conditions;（４）夜间出现的背景亮光，诸如来自岸上的灯光或本船灯光的反向散射；(iv) at night the presence of background light such as from shore lights or from back scatter of her own lights;（５）风、浪和流的状况以及靠近航海危险物的情况；(v) the state of wind, sea and current, and the proximity of navigational hazards;（６）吃水与可用水深的关系。(vi) the draught in relation to the available depth of water.２．对备有可使用的雷达的船舶，还须考虑：(b) Additionally, by vessels with operational radar: （１）雷达设备的特性、效率和局限性； (i) the characteristics, efficiency and limitations of the radar equipment; （２）所选用的雷达距离标尺带来的任何限制； (ii) any constraints imposed by the radar range scale in use;（３）海况、天气和其他干扰源对雷达探测的影响； (iii) the effect on radar detection of the sea state, weather and other sources of interference;（４）在适当距离内，雷达对小船、浮冰和其他漂浮物胃探测不到的可能性； (iv) the possibility that small vessels, ice and other floating objects may not be detected by radar at an adequate range; （５）雷达探测到的船舶数目、位置和动态；(v) the number, location and movement of vessels detected by radar;（６）当用雷达测定附近船舶或其他物体的距离时，可能对能见度作出更确切的估计。(vi) the more exact assessment of the visibility that may be possible when radar is used to determine the range of vessels or other objects in the vicinity.第七条 碰撞危险 Rule 7 Risk of collision１．每一船舶应用适合当时环境和情况的一切有效手段断定是否存在碰境危险，如有任何怀疑，则应认为存在这种危险。(a) Every vessel shall use all available means appropriate to the prevailing circumstances and conditions to determine if risk of collision exists. If there is any doubt such risk shall be deemed to exist. ２．如装有雷达设备并可使用的话，则应正确予以使用，包括远距离扫瞄，以便获得碰撞危险的早期警报，并对探测到的物标进行雷达标绘或与其相当的系统观察。(b) Proper use shall be made of radar equipment if fitted and operational, including long-range scanning to obtain early warning of risk of collision and radar plotting or equivalent systematic observation of detected objects.３．不应根据不充分的资料，特别是不充分的雷达观测资料作出推断。(c) Assumptions shall not be made on the basis of scanty information, especially scanty radar information.４．在断定是否存在碰撞危险时，考虑的因素中应包括下列各点：(d) In determining if risk of collision exists the following considerations shall be among those taken into account:（１）如果来船的罗经方位没有明显的变化，则应认为存在这种危险；(i) such risk shall be deemed to exist if the compass bearing of an approaching vessel does not appreciably change, （２）即使有明显的方位变化，有时也可能存在这种危险，特别是在驶近一艘很大的船舶或拖带船组时，或是在近距离驶近他船时。(ii) such risks may sometimes exist even when an appreciable bearing change is evident, particularly when approaching a very large vessel or a tow or when approaching a vessel at close range.第八条 避免碰撞的行动 Rule 8 Action to avoid collision１．为避免砬撞所采取的任何行动，如当时环境许可，应是积极地，并应及早地进行和注意运用良好的船艺。 (a) Any action taken to avoid collision shall, if the circumstances of the case admit, be positive, made in ample time and with due regard to the observance of good seamanship. ２．为避免碰撞而作的航向和（或）航速的任何变动，如当时环境许可，应大得足以使他船用视觉或雷达观察时容易察觉到；应避免对航向和（或）航速作一连串的小变动。 (b) Any alteration of course and/or speed to avoid collision shall, if the circumstances of the case admit, be large enough to be readily apparent to another vessel observing visually or by radar; a succession of small alterations of course and/or speed should be avoided.３．如有足够的水域，则单用转向可能是避免紧迫局面的最有效行动，倘若这种行动是及时的，大幅度的并且不致造成另一紧迫局面。(c) lf there is sufficient sea room, alteration of course alone may be the most effective action to avoid a close-quarters situation provided that is made in good time, is substantial and does not result in another close-quarters situation.４．为避免与船碰撞而采取的行动，应能导致在安全的距离驶过。应细心查核避让行动的有效性，直到最后驶过让清他船为止。(d) Action taken to avoid collision with another vessel shall be such as to result in passing at a safe distance. The effectiveness of the action shall be carefully checked until the other vessel is finally past and clear.５．如须避免碰撞或须留有更多时间来估计局面，船舶应当减速或者停止或倒转推进器把船停住。(e) If necessary to avoid collision or allow more time to assess the situation, a vessel shall slacken her speed or take all way off by stopping or reversing her means of propulsion.第九条 狭水道 Rule 9 Narrow channels１．船舶沿狭水道或航道行驶时，只要安全可行，应尽量靠近本船右舷的该水道或航道的外缘行驶。 (a) A vessel proceeding along the course of a narrow channel or fairway shall keep as near to the outer limit of the channel or fairway which lies on her starboard side as is safe and practicable. ２．帆船或者长度小于２０米的船舶，不应妨碍只能在狭水道或航道以内安全航行的船舶通行。(b) A vessel of less than 20 metres in length or a sailing vessel shall not impede the passage of a vessel which can safely navigate only within a narrow channel or fairway.３．从事捕鱼的船舶，不应妨碍任何其他在狭水道或航道以内航行的船舶通行。(c) A vessel engaged in fishing shall not impede the passage of any other vessel navigating within a narrow channel or fairway. ４．船舶不应穿越狭水道或航道，如果这种穿越会妨碍只能在这种水道或航道以内安全航行的船舶通行。后者若对穿越船的意图有怀疑时，可以使用第三十四条第４款所规定的声号。(d) A vessel shall not cross a narrow channel or fairway if such crossing impedes the passage of a vessel which can safely navigate only within such channel or fairway. The latter vessel may use the sound signal prescribed in Rule 34(d) if in doubt as to the intention of the crossing vessel.５．（１）在狭水道或航道内，如只有在被追越船必须采取行动以允许安全通过才能追越时，则企图追越的船，应鸣放第三十四条第３款（１）项所规定的相应声号，以表示本船的意图。被迫越船如果同意，应呜放第三十四条３款（２）项所规定的相应声号，并采取使之能安全通过的措施。如有怀疑，则可以鸣放第三十四条第４款所规定的声号。(e) (i) In a narrow channel or fairway when overtaking can take place only if the vessel to be overtaken has to take action to permit safe passing, the vessel intending to overtake shall indicate her intention by sounding the appropriate signal prescribed in Rule 34(c)(i). The vessel to be overtaken shall, if in agreement, sound the appropriate signal prescribed in Rule 34(c)(ii) and take steps to permit safe passing.
