Fed. R. Civ. P. D
In all actions for possession, partition, and to try title maintainable according to the course of the admiralty practice with respect to a vessel, in all actions so maintainable with respect to the possession of cargo or other maritime property, and in all actions by one or more part owners against the others to obtain security for the return of the vessel from any voyage undertaken without their consent, or by one or more part owners against the others to obtain possession of the vessel for any voyage on giving security for its safe return, the process shall be by a warrant of arrest of the vessel, cargo, or other property, and by notice in the manner provided by Rule B(2) to the adverse party or parties.
28 APPENDIX U.S.C. § D
NOTES OF ADVISORY COMMITTEE ON RULES This carries forward the substance of Admiralty Rule 19. Rule 19 provided the remedy of arrest in controversies involving title and possession in general. See The Tilton, 23 Fed. Cas. 1277 (No. 14, 054) (C.C.D. Mass. 1830). In addition it provided that remedy in controversies between co-owners respecting the employment of a vessel. It did not deal comprehensively with controversies between co-owners, omitting the remedy of partition. Presumably the omission is traceable to the fact that, when the rules were originally promulgated, concepts of substantive law (sometimes stated as concepts of jurisdiction) denied the remedy of partition except where the parties in disagreement were the owners of equal shares. See The Steamboat Orleans, 36 U.S. (11 Pet.) 175 (1837). The Supreme Court has now removed any doubt as to the jurisdiction of the district courts to partition a vessel, and has held in addition that no fixed principle of federal admiralty law limits the remedy to the case of equal shares. Madruga v. Superior Court, 346 U.S. 556 (1954). It is therefore appropriate to include a reference to partition in the rule.
