A ship's manager has the authority to perform any and all acts in and out of court on behalf of the part owners of the ship in connection with the use of the ship, except for those set forth in the following:
船舶管理人は、次に掲げる行為を除き、船舶共有者に代わって船舶の利用に関する一切の裁判上又は裁判外の行為をする権限を有する。
embarking on a new voyage (limited to one that has not been planned among the part owners of the ship);
新たな航海（船舶共有者の間で予定されていなかったものに限る。）をすること。
borrowing money.
借財をすること。
A limitation on the ship's manager's authority to act as agent may not be asserted against a third party in good faith.

ship
「船舶」
In the part on maritime commerce (except Article 747), a ship used for navigation for the purpose of commercial transactions (商行為), other than rowboats and other boats driven only or mainly by oars.
Defined inArticle 684, paragraph (1)
assert against
対抗
To be able to rely on a right, or on a fact about it, against someone who is not a party to it. Acquiring, losing or changing a right in rem (物権) in land or a building cannot be asserted against third parties until it is registered (登記) (Civil Code, Article 177), and a registered lease of land or a building can be asserted against a person who acquires a right in rem in it, such as a buyer, and against other third parties (Article 605). The Act on Land and Building Leases lets a tenant do without registering the lease itself: a right to use land for a building (借地権) can be asserted against third parties once the tenant owns a registered building on the land (Article 10, paragraph (1)), and a building lease takes effect against anyone who later acquires a right in rem in the building, such as a new owner, once the building has been handed over (Article 31). Some rules protect only a third party who did not know: a rescission for fraud cannot be asserted against a third party who did not know of the fraud and was not careless in not knowing (善意でかつ過失がない) (Civil Code, Article 96, paragraph (3)).
