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,包含远距离扫描,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不雅察.(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．不理当按照不充分的资料,特别是不充分的雷达不雅测资料作出推断.(c) Assumptions shall not be made on the basis of scantyinformation, especially scanty radar information.4．在断定是否存在碰撞危险时,考虑的因素中应包含下列各点：(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更,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更,有时也可能存在这种危险,特别是在驶近一艘很大的船或拖带船组时,或是在近距离驶近他船时.(ii) Such risk 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 Rule 8避免碰撞的行动 Action to Avoid Collision1．为避免碰撞所采纳的任何行动,如当时环境许可,应是积极的,应及早地进行和充分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 inample time and with due regard to the observance of good seamanship.2．为避兔碰撞而作的航向和（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不雅测时容易觉察到；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,只要这种行动是及时的、大幅度的,并且不致造成另一紧迫局面.(c) If there is sufficient sea room, alteration of course alone may be the most effective action to avoid a close-quarters situation provided that it is made in good time, is substantial and does not result in another close-quarters situation.4．为避免与他船碰撞而采纳的行动,应能导致在平安的距离驶过.应细心查核躲避行动的有效性,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．如需为避免碰撞或留有更多的时间来估量局面,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 may slacken her speed or take all way off by stopping or reversing her means of propulsion.6．（1）按照本规则任何规定,要求不得妨害另一船通过或平安通过的船舶应按照当时环境的需要及早地采纳行动以留出足够的水域供他船平安通过.(f) (i) A vessel which, by any of these rules, isrequired not to impede the passage or safe passage of another vessel shall when required by the circumstances of the case, take early action to allow sufficient sea room for the safe passage of the other vessel.（2）如果在接近其他船舶致有碰撞危险时,被要求不得妨害另一船通过或平安通过的船舶其实不解除这一责任,且当采纳行动时,应充分考虑到本章条款可能要求的行动.(ii) A vessel required not to impede the passage or safe passage of another vessel is not relieved ofthis obligation if approaching the other vessel so as to involve risk of collision and shall, when taking action, have full regard to the action which may be required by the rules of this part.（3）当两船相互接近致有碰撞危险时,其通过不得被妨害的船舶仍有完全遵守本章各条规定的责任.(iii) A vessel the passage of which is not to be impeded remains fully obliged to comply with the rules of this part when the two vessels are approaching one another so as to involve risk of collision.第九条 Rule 9狭水道 Narrow Channels1．沿狭水道或航道行驶的船舶,只要平安可行,应尽量靠近其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 Iies on her starboard side as is safe and practicable.2．风帆或者长度小于20米的船舶,不该妨害只能在狭水道或航道以内平安航行的船舶通行.(b) A vessel of less than 20 meters in length or a sailing vessel shall not impede the passage of a vesselwhich can safely navigate only within a narrow channel or fairway.3．从事打鱼的船舶,不该妨害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、船舶不该穿越狭水道或航道,如果这种穿越会妨害只能在这种水道或航道以内平安航行的船舶通行.后者若对穿越船的意图有怀疑时,可以使用第三十四条4款规定的声号.(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,如只有在自愿越船必须采纳行动以允许平安通过才干追越时,则企图迫越的船,应鸣放第三十四条3款（1）项所规定的相应声号,以暗示其意图.被追越船如果同意,应鸣放第三十四条3款（2）项所规定的相应声号,并采纳使之能平安通过的措施.如有怀疑,则可以鸣放第三十四条4款所规定的声号.(e) (I) In a narrow channel or fairway when overtakingcan 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.If in doubt she may sound the signals prescribed in Rule 34(d).（2）本条其实不解除追越船按照第十三条所负的义务.(ii) This Rule does not relieve the overtaking vessel of her obligation under Rule 13.6．船舶在驶近可能有其他船舶被居间障碍物遮蔽的狭水道或航道的弯头或地段时,应特别机警和谨慎地驾驶,并应呜放第三十四条5款规定的相应声号.(f) A vessel nearing a bend or an area of a narrow channel or fairway where other vessels may be obscured by an intervening obstruction shall navigate with particular alertness and cautionand shall sound the appropriate signal prescribed in Rule34(e).7．任何船舶,如当时环境许可,都应避免在狭水道内锚泊.(g) Any vessel shall, if the circumstances of the case admit, avoid anchoring in a narrow channel.第十条 Rule 10分道通航制 Traffic Separation Schemes1．本条适用于本组织采取的分道通航制,但其实不解除任何船舶遵守任何其他各条规定的责任.(a) This Rule applies to traffic separation schemes adopted by the Organization and does not relieve any vessel of her obligation under any other rule.2．使用分道通航制区域的船舶应：(b) A vessel using a traffic separation scheme shall:（1）在相应的通航分道内顺着该分道的船舶总流向行驶；(i) proceed in the appropriate traffic lane in the general direction of traffic flow for that lane;（2）尽可能让开通航分隔线或分隔带；(ii) so far as practicable keep clear of a traffic separation line or separation zone;（3）通常在通航分道的端部驶进或驶出,但从分道的任何一侧驶进或驶出时,应与分道的船舶总流向形成尽可能小的角度. (iii) normally join or leave a traffic lane at thetermination of the lane, but when joining or leaving from either side shall do so at as small an angle to the general direction of traffic low as practicable. 3．船舶应尽可能避免穿越通航分道,但如不克不及不穿越时,应尽可能用与分道的船舶总流向成直角的船首向穿越.(c) A vessel shall, so far as practicable, avoid crossing traffic lanes but if obliged to do so shall cross on a heading as nearly as practicable at right angles to the general direction of traffic flow.4．（1）当船舶可平安使用邻近分道通航制区域中相应通航分道时,不该使用沿岸通航带.但长度小于20米的船舶、风帆和从事打鱼的船舶可使用沿岸通航带.(d) (i) A vessel shall not use an inshore traffic zonewhen she can safely use the appropriate traffic lane within the adjacent traffic separation scheme.However, vessels of less than 20 meters in length, sailing vessels and vessels engaged in fishing may use the inshore traffic zone.（2）尽管有本条4（1）规定,当船舶抵离位于沿岸通航带中的口岸、近岸设施或建筑物、引航站或任何其他地方或为避免紧迫危险时,可使用沿岸通航带.(ii) Notwithstanding subparagraph (d)(i), a vessel may use an inshore traffic zone when en route to or froma port, offshore installation or structure, pilotstation or any other place situated within the inshore traffic zone, or to avoid immediate danger. 5．除穿越船或者驶进或驶出通航分道的船舶外,船舶通常不该进人分隔带或穿越分隔线,除非：(e) A vessel other than a crossing vessel or a vessel joining or leaving a lane shall not normally enter a separation zone or cross a separation line except:（1）在紧急情况下避免紧迫危险；(i) in cases of emergency to avoid immediate danger;（2）在分隔带内从事打鱼.(ii) to engage in fishing within a separation zone. 6．船舶在分道通航制区域端部邻近行驶时,应特别谨慎.(f) A vessel navigating in areas near the terminations of traffic separation schemes shall do so with particular caution.7．船舶应尽可能避免在分道通航制区域内或其端部邻近锚泊. (g) A vessel shall so far as practicable avoid anchoring in a traffic separation scheme or in areas near its terminations.8．不使用分道通航制区域的船舶,应尽可能远离该区.(h) A vessel not using a traffic separation scheme shall avoid it by as wide a margin as is practicable.9．从事打鱼的船舶,不该妨害按通航分道行驶的任何船舶的通行.(i) A vessel engaged in fishing shall not impede the passage of any vessel following a traffic lane.10．风帆或长度小于20米的船舶,不该妨害按通航分道行驶的机动船的平安通行.(j) A vessel of less than 20 meters in length or a sailing vessel shall not impede the safe passage of a power-driven vessel following a traffic lane.11. 把持能力受到限制的船舶,当在分道通航制区域内从事维护航行平安的作业时,在执行该作业所必须的限度内,免受本条规定的约束.(k) A vessel restricted in her ability to maneuver when engaged in an operation for the maintenance of safety of navigation in a traffic separation scheme is exempted from complying with this Rule to the extent necessary to carry out the operation.12．把持能力受到限制的船舶,当在分道通航制区域内从事敷设、维修或起捞海底电缆时,在执行该作业所必须的限度内,免受本条规定的约束.(l) A vessel restricted in her ability to maneuver when engaged in an operation for the laying, servicing or picking up of a submarine cable, within a traffic separation scheme, is exempted from complying with this Rule to the extent necessary to carry out the operation.第二节船舶在互见中的行动规则Section II - Conduct of Vessels in Sight of One Another第十一条 Rule 11适用范围 Application本节条款适用于互见中的船舶.Rules in this Section apply to vessels in sight of one another.第十二条 Rule 12帆船 Sailing Vessels1．两艘风帆相互驶近致有组成碰撞危险时,其中一船应按下列规定给他船让路：(a) When two sailing vessels are approaching one another, so as to involve risk of collision, one of them shall keep out of the way of the other as follows:（1）两船在不合舷受风时,左舷受风的船应给他船让路；(i) when each has the wind on a different side, thevessel which has the wind on the port side shallkeep out of the way of the other;（2）两船在同舷受风时,上风船应给下风船让路；(ii) when both have the wind on the same side, the vessel which is to windward shall keep out of theway of the vessel which is to leeward;（3）如左舷受风的船看到在上风的船而不克不及断定究竟该船是左舷受风还是右舷受风,则应给该船让路.(iii) if a vessel with the wind on the port side sees a vessel to windward and cannot determine withcertainty whether the other vessel has the wind onthe port or on the starboard side, she shall keepout of the way of the other.2．就本条规定而言,船舶的受风舷侧应认为是主帆被吹向的一舷的对面舷侧；对于方风帆,则应认为是最大纵帆被吹向的一舷的对面舷侧.(b) For the purposes of this Rule the windward side shall be deemed to be the side opposite to that on which the mainsail is carried or, in the case of a square-rigged vessel, the side opposite to that on which the largest fore-and-aft sail is carried.第十三条 Rule 13追越 Overtaking1.不管第二章第一节和第二节的各条规定如何,任何船舶在追越任何他船时,均应给被追越船让路.(a) Notwithstanding anything contained in the Rules of Part B, Sections I and II any vessel overtaking any other shall keep out of the way of the vessel being overtaken. 2．一船正从他船正横后大于22．5度的某一标的目的遇上他船时,即该船对其所追越的船所处的位置,在夜间只能看见被追越船的尾灯而不克不及看见它的任一舷灯时,应认为是在追越中.(b) A vessel shall be deemed to be overtaking when coming up with another vessel from a direction more than 22.5 degrees abaft her beam, that is, in such a position with reference to the vessel she is overtaking, that at night she would be able to see only the stern light of that vessel but neither of her sidelights.3.当一船对其是否在追越他船有任何怀疑时,该船应假定是在追越,并应采纳相应行动.(c) When a vessel is in any doubt as to whether she is overtaking another, she shall assume that this is the case and act accordingly.4．随后两船间方位的任何改动,都不该把追越船作为本规则条款含义中所指的交叉相遇船,或者免除其让开被追越船的责任,直到最后驶过让清为止.(d) Any subsequent alteration of the bearing between the two vessels shall not make the overtaking vessel a crossing vessel within the meaning of these Rules or relieve her of the duty of keeping clear of the overtaken vessel until she is finally past and clear.第十四条 Rule 14对遇局面 Head-On Situation1. 当两艘机动船在相反的或接近相反的航向上相遇致有组成碰撞危险时,各应向右转向,从而各从他船的左舷驶过.(a) When two power-driven vessels are meeting on reciprocal or nearly reciprocal courses so as to involve risk of collision each shall alter her course to starboard so that each shall pass on the port side of the other.2．当一船看见他船在正前方或接近正前方,并且,在夜间能看见他船的前后桅灯成一直线或接近一直线和（或）两盏舷灯；在白日能看到他船的上述相应形态时,则应认为存在这样的局面.(b) Such a situation shall be deemed to exist when a vessel sees the other ahead or nearly ahead and by night she could see the masthead lights of the other in a line or nearly in a line and/or both sidelights and by day she observes the corresponding aspect of the other vessel.3．当一船对是否存在这样的局面有任何怀疑时,该船应假定确实存在这种局面,并应采纳相应的行动.(c) When a vessel is in any doubt as to whether such a situation exists she shall assume that it does exist and act accordingly.第十五条 Rule 15交叉相遇局面 Crossing Situation当两艘机动船交叉相遇致有组成碰撞危险时,有他船在哪有或船舶应给他船让路,如当时环境许可,还应避免横越他船的前方.When two power-driven vessels are crossing so as to involve risk of collision, the vessel which has the other on her own starboard side shall keep out of the way and shall, if the circumstances of the case admit, avoid crossing ahead of the other vessel.第十六条 Rule 16让路船的行动 Action by Give-way Vessel须给他船让路的船舶,应尽可能及早地采纳大幅度的行动,宽裕地让清他船.Every vessel which is directed to keep out of the way of another vessel shall, so far as possible, take early and substantial action to keep well clear.第十七条 Rule 17直航船的行动 Action by Stand-on Vessel1．（1）两船中的一船应给另一船让路时,另一船应坚持航向和航速.(a) (i) Where one of two vessels is to keep out of the way the other shall keep her course and speed.（2）然而,当坚持航向和航速的船一经觉察规定的让路船显然没有遵照本规则条款采纳适当行动时,该船即可独自采纳把持行动,以避免碰撞.(ii) The latter vessel may however take action to avoid collision by her maneuver alone, as soon as it becomes apparent to her that the vessel required to keep out of the way is not taking appropriate action in compliance with these Rules.2．当规定坚持航向和航速的船,觉察本船不管由于何种原因迫近到单凭让路船的行动不克不及避免碰撞时,也应采纳最有助于避碰的行动.(b) When, from any cause, the vessel required to keep her course and speed finds herself so close that collision cannot be avoided by the action of the give-way vessel alone, she shall take such action as will best aid to avoid collision.3．在交叉相遇的局面下,机动船依照本条二款（2）项采纳行动以。

1972年国际海上避碰规则英文

The COLREGs consist of 38 rules that cover a wide range of topics related to navigation and the conduct of vessels. These rules aim to promote the safety of navigation and provide a universal framework for mariners to follow in order to avoid collisions.Rule 1 of the COLREGs establishes the scope and application of the regulations. It states that the rules apply to all vessels upon the high seas and in all waters connected to the high seas and navigable by seagoing vessels.Rule 2 provides definitions for various terms used throughout the COLREGs. These definitions ensure that there is a clear understanding of the terminology used in the regulations.Rule 3 states that vessels should be operated at a safe speed and in a manner that allows for proper and effective action to avoid collisions. This rule emphasizes the importance of maintaining a watchful outlook and being alert to the presence of other vessels.Rules 4 to 10 outline the requirements for vessels to display navigation lights and signals. These rules specify the types of lights that should be used during different conditions, such as at night or in restricted visibility.Rules 11 to 18 cover the conduct of vessels in different scenarios. For example, Rule 11 states that a vessel shall keepa good lookout by sight and hearing in order to determine whether there is risk of collision.Rule 18 addresses the responsibilities between vessels in restricted visibility. It states that a vessel should proceed at a safe speed and navigate in a manner that avoids collision and minimizes the risk of its navigation being hindered by limited visibility.Rules 19 to 24 discuss maneuvering and the conduct of vessels in various situations, such as overtaking, crossing, and head-on encounters. These rules provide guidelines for theright-of-way between vessels and establish principles for vessels to follow to avoid collisions.Rules 25 to 38 cover important topics such as traffic separation schemes, navigation in narrow channels, and responsibilities between vessels in distress. These rules provide specific instructions for navigating in areas where there is a high volume of vessel traffic to prevent accidents and ensure safe navigation.。

1972年国际海上避碰规则英文

The International Regulations for Preventing Collisions at Sea, also known as the COLREGs, were first adopted in 1972.These regulations are a set of rules that govern the actions and behaviors of vessels when navigating at sea to ensure the safety of all parties involved. This article will provide an overviewof the 1972 International Regulations for Preventing Collisionsat Sea in more than 1200 words.Part A of the COLREGs contains general rules that apply toall vessels and all conditions. These rules include the fundamental principles of safe navigation such as maintaining a proper lookout, taking action to avoid a collision when the vessel has the right of way, and using all available means to determine whether a risk of collision exists.Part B focuses on navigating in restricted visibility, such as fog or heavy rain. It provides guidance on actions to betaken when encountering another vessel in these conditions, including appropriate sound signals to indicate the presence, position, and maneuvering intentions of the vessel.Part D outlines the markings and shapes required to be displayed by vessels during specific circumstances or operations. For example, it requires vessels involved in fishing to display appropriate shapes or lights to indicate their fishingactivities to other vessels to avoid tangling or collision.。
