Ship owner’s lien
The lien that a ship-owner has for freight and other charges attaching to the goods that he carries. This lien may even exist when the goods have been warehoused if notice has been given to this effect. The lien for freight or general average contributions is a possessory lien. The lien for other expenses in protecting the goods is a maritime lien.
