state lien on vessel

Wherever any lien is given by a state statute for a cause of action cognizable in admiralty, either in rem or in personam, proceedings in rem to enforce such lien are within the exclusive jurisdiction of the admiralty courts. But the converse of this proposition is equally true, that if a lien upon a vessel be created for a claim over which a court of admiralty has no jurisdiction in any form, such lien may be enforced in the courts of the state.
