《船舶避碰》复习题 例1．《国际海上避碰规则》适用的船舶是指： A.在公海上的一切船舶 B.在公海以及连接公海而可供海船航行的一切水域中的在航船舶和锚泊船 C.除内河船舶之外的任何船舶 D. 在公海以及连接公海可供海船航行的一切水域中的一切船舶 【解答】本题选D。本题宜采用“规则条款对号入座法”。对于测试规则条款的考题，应牢记条款原文（中文翻译），通常含有规则条款原文的选项即为正确选项。按照这一原则，本题应选D。D选项既讲明了规则适用的水域，又讲明了规则适用的对象，为最佳答案。题设中的A、B、C三选项均在规则的适用水域或适用对象方面有所欠缺。 例2．《国际海上避碰规则》适用的船舶包括：Ⅰ、在水面航行的水上飞机Ⅱ、超低空飞行的飞机Ⅲ、拖航中的钻井平台 A. Ⅰ B. Ⅱ C. Ⅰ、Ⅲ D. Ⅰ、Ⅱ、Ⅲ 【解答】本题选C。本题测试对规则适用船舶的理解，规则适用的船舶是“公海和连接于公海而可供海船航行的一切水域中的一切船舶”，题设中的第Ⅱ项“超低空飞行的飞机”不属于规则第三条中定义的“船舶”。因此，本题正确选项为C。 例3．下列哪些说法正确? A. 任何特殊构造或用途的船舶，只要其政府确定，即可自行制定有关号灯、号型的配置、安装等技术方面的规定 B. 有关政府有权为其管辖下的任何特殊构造或用途的船舶制定有关号灯、号型的数量、位置、能见距离、弧度的规定尽可能符合《国际海上避碰规则》条款的规定

C. 上述的特殊规定应尽可能不致被误认为《国际海上避碰规则》其它各条规定的号灯、号型或信号 D. 任何特殊构造或用途的船舶应显示特殊的尽可能不致被误认为《国际海上避碰规则》其它各条规定的号灯、号型或信号 【解答】本题选B。本题考查的是对规则第一条第5款的理解与记忆。A选项的错误之处在于“可自行制定”用词错误，有关政府在为其管辖下的任何特殊构造或用途的船舶制定有关号灯、号型的数量、位置、能见距离、弧度的规定应尽可能符合本规则条款的规定；C、D选项中的“尽可能不致被误认为”应该为“尽可能符合”；题设中只有B选项正确。 例4．关于特殊的避碰规则或规定，下列说法正确的是? A. 各沿海国家的特殊规定，必须由政府统一制定 B. 有关主管机关可在其管辖的一切水域内制定任何特殊的避碰规定 C. 任何船舶均应当遵守有关主管机关在其管辖水域内制定的特殊避碰规定 D. 特殊水域的特殊避碰规定，由IMO统一制定 【解答】本题选C。 例1.《国际海上避碰规则》第三条“定义”中提及的“机动船”一词应包括：Ⅰ、正在用机器推进的任何船舶Ⅱ、限于吃水的船舶Ⅲ、用机器推进的从事捕鱼的船舶Ⅳ、正在从事拖带作业的船舶 A. Ⅰ、Ⅱ、Ⅲ、Ⅳ B. Ⅰ、Ⅱ、Ⅲ C. Ⅰ、Ⅱ D. Ⅰ 【解答】本题选A。本题考察对“机动船”定义的理解。规则第三条“定义”中指出“机动船指用机器推进的任何船舶”，属于广义机动船。本题的题设Ⅰ毫无疑问属于机动船；题设Ⅱ——限于吃水的船舶其构成条件之一就是必须为机动船；题设Ⅲ明确了“用机器推进的从事捕鱼

中国加入海事海商国际公约一览

中国加入海事海商国际公约一览 从我国加入并生效的国际公约以及我国立法借鉴的公约看，时间上都是在改革开放以后，加入公约时，我国政府以我国经济社会发展水平为立足点，充分考量到了航运业发展和国际经济贸易的发展，对于船员权利的保护以及船舶所有人的利益进行了很好的关注，做到既谨慎，又积极。加入公约后，国内立法上也进行了适当的配合,如《海商法》对《1989年救助公约》的借鉴；对于有些公约，如《1976海事赔偿责任限制公约》，我国虽然没有加入，但是也在国内立法上进行了模仿，最大限度上与国际接轨，进而完善我国海商法体系。 以下是我整理的与我国海事海商立法关系密切的几个公约，按对中国生效时间顺序排列，第二十三、第二十四是国际劳工组织公约故放在后边，第二十五、二十六为未对我国生效、但是我国海商法借鉴引用： 船舶：《1966年国际载重线公约》 《1976年国际海事卫星组织公约》 《1993年船舶优先权和抵押权国际公约》 《1969年船舶吨位丈量国际公约》 《1988年制止危及海上航行安全非法行为公约》及 《1988年制止危及大陆架固定平台安全非法行为议定书》 船员：《1974年国际海上人命安全公约》 《1978海员培训、发证和值班标准国际公约》 《1926年海员遣返公约》 《海员协议条款公约》 国际海上运输：《1972年国际集装箱安全公约》 《1974年联合国班轮公会行动守则公约》（联合国） 《1965年便利国际海上运输公约》《1974年海上旅客及其行李运输雅典公约》 船舶碰撞：《1910年统一船舶碰撞某些法律规定的国际公约》 《1972年国际海上避碰规则公约》 《1952年船舶碰撞中民事管辖权方面某些规定的国际公约》
