题目解答
答案
解析
本题考查对《国际海上避碰规则》中“操纵能力受到限制的船舶”定义的理解。解题思路是明确操纵能力受到限制的船舶的具体类型,然后逐一分析每个选项是否符合该定义。
选项A
A vessel which has lost the use of her steering gear (失去舵效的船舶),根据规则,失去舵效的船舶属于“失控船舶”,而不是“操纵能力受到限制的船舶”。失控船舶是指由于某种异常情况,不能按本规则的要求进行操纵,因而不能给他船让路的船舶。所以选项A不符合要求。
选项B
A vessel fishing with trawls (用拖网捕鱼的船舶),用拖网捕鱼的船舶属于“从事捕鱼的船舶”,虽然从事捕鱼的船舶在某些情况下操纵能力会受到一定限制,但它有专门的分类,不属于“操纵能力受到限制的船舶”这一类别。所以选项B不符合要求。
选项C
A vessel with a draft of such depth that she cannot change her course (吃水过深以致不能改变航向的船舶),仅仅因为吃水过深不能改变航向,并不能直接认定该船舶属于“操纵能力受到限制的船舶”。操纵能力受到限制的船舶通常是由于执行特定作业或任务而导致操纵能力受限。所以选项C不符合要求。
选项D
A vessel engaged in mine clearance operation (从事扫雷作业的船舶),根据《国际海上避碰规则》,从事扫雷作业的船舶属于操纵能力受到限制的船舶。这类船舶由于其作业性质,在操纵上受到很大限制,需要其他船舶给予特别的注意和避让。所以选项D符合要求。
