California Harbors and Navigation Code
The provisions of this Division shall not be construed to apply to the extent to which they are not within the legislative power of this state, except in so far as they may be permitted to apply under the provisions of the Constitution of the United States or the acts of Congress.
"Appurtenances" include all things belonging to the owners, which are on board a vessel, and which are connected with its proper use and the objects of the voyage and adventure in which it is engaged.
Vessels are engaged in foreign or domestic navigation, or in the fisheries. Vessels are engaged in foreign navigation when passing to or from a foreign country; and in domestic navigation, when passing from place to place within the United States.
A vessel in a port of the country in which it is registered is called a domestic vessel, in another port it is called a foreign vessel.
If a vessel belongs to several persons, not partners, and they differ as to its use or repair, the controversy may be determined by any court of competent jurisdiction.
If the owner of a vessel commits its possession and navigation to another, that other, and not the owner, is responsible for its repairs and supplies.
The registry, enrollment, and license of vessels are regulated by acts of Congress.
Any and all rights and obligations created pursuant to the provisions of Chapter 2 (commencing with Section 450) of this division are subordinate to any superseding federal law.
