Maritime liens are a fascinating part of maritime law, encompassing both substantive and procedural aspects quite different from common law liens and security interests. This Article will focus on one aspect of maritime lien law, the objects to which such liens attach, and will discuss recent developments affecting the fishing industry. This Article will also address the definition of maritime liens from a historical and current perspective, as well as the “appurtenances” to which maritime liens attach. It will analyze whether maritime liens attach to intangibles, such as the rights granted under statutory and regulatory rules applicable to the fishing permits and fishing histories that make commercial fishing vessels so valuable, and indeed, functional.
