船舶作为一种交通运输工具每个国家都对其进行了法律意义上的确认。一艘船舶要取得航行权,首先必须在某国注册登记而取得国籍证明文件,并悬挂该国的国旗。船籍国制定法律、规章和航运政策,对船舶的航行安全和人员配备及培训等方面进行监管。由于船舶从事国际海上运输,经常处于不断的位移之中,在有些情况下难以确定船舶所在地。船舶航行于公海上时,原则上,只有船籍国才能对其行使权利。因此,船籍法被认为是海事法律选择的基本原则,与物之所在地法,侵权行为地法,法院地法相比,船籍国法则居于较为重要的地位。 Ships as a means of transport each country have legally recognized it. To obtain the right of navigation, a ship must first obtain a nationality proof by registering in a certain country and flying the national flag of that country. The countries of registry have laws, regulations and shipping policies that govern the safety of navigation and staffing and training of ships. Since ships are engaged in international maritime transport, they are constantly in constant displacement and in some cases it is difficult to determine the location of the ship. When ships are sailing on the high seas, in principle, only the country of registry can exercise their rights. Therefore, the boat registration law is considered as the basic principle of the choice of maritime law. Compared with the law of the place where the property is located, the law of tort and the law of the court, the law of the country of registry is more important.
