The changes since the first edition in 1991, are extensive. Chapters on Constitutional Background and Jurisdiction of Courts and Prize; Prize Salvage; Bounty and Ransom have been brought up to date. Chapters on Actions in Rem; Arrest of Ships; Maritime Liens, Carriage of Goods by Sea, Sea Carriage Documents, Marine Insurance, Charterparties and Maritime Securities have been reworked and updated, whilst the chapter on Navigation; Collisions and Liability; Marine Inquiries has been almost completely rewritten to include many issues not covered in the first edition. The chapter on Salvage; Towage; Wreck & Pilotage had to be rewritten to take account of amendments to the Navigation Act 1912 (Cth), which give effect to the International Convention on Salvage 1989 that changes much of the law. The chapter on Limitation of Liability also had to be completely rewritten, to take account of the Convention on Limitation of Liability for Maritime Claims 1976. The Convention has been implemented in Australia by the Limitation of Liability for Maritime Claims Act 1989 (Cth). Finally, the chapter on International Maritime Institutions is a new addition to the book. Professor Gold's chapter on International Maritime Organisations gives an introduction to the large number of international maritime entities that play an important role in marine law. The law discussed in the text is as at May 2000 for most chapters.
