0.1 Of what legal consequence is it that a claim is “maritime” in nature—or, to put it another way “lies in Admiralty”? This book deals with the jurisdictional, remedial and security consequences which follow simply from the inclusion of a claim within Admiralty jurisdiction. Naturally, in any legal system, any particular consequences are built on and into the framework of that system as a whole. It is, therefore, essential to consider not only the rules applicable to Admiralty as such but those governing claims generally and applied to maritime as any other claims. Note must thereby be carefully taken of domestic differences between Admiralty and other claims.
