YORK-ANTWERP RULES 581 owners, the amount being determined annually by the total tonnage of the ships owned by the firm and the extent of the claims paid by the Mutual Insurance Association. General Average arises when some loss or expense has been wilfully and voluntarily incurred in order to save the ship and cargo, or what remains of them. It is termed " General," because the loss is borne generally by all interested in the ship, freight and cargo, each one's share of the loss being proportioned to the value he had at stake. York-Antwerp Rules.—These form a code of rules for the settlement of cases of General Average, and are now universally adopted. They only apply, however, when expressly agreed upon in the charter-party and bills of lading. Where this is not done the average would be settled according to British law, which differs from the York-Antwerp Rules in one or two respects. The Rules define broadly what may or may not be made good under general and particular average, and they serve as a guide to average adjusters in deciding how the various interests involved in the venture shall contribute their financial share of the loss. The rules are recorded under the headings of :—Damage to ship and cargo in consequence of jettisoning cargo. Jettison of deck cargo is not made good as general average. Extinguishing fire on shipboard and the resultant damage toy fire and water. Cutting away wreck. Voluntarily running the ship ashore to avoid total loss or greater damage. Damage to engines in the endeavour to refloat. Expenses incurred in lightening a ship when ashore. Cargo and material burnt for fuel if ship runs short of bunkers through unforeseen circumstances. Expenses at port of refuge in discharging, storing and reloading cargo and damage to cargo during the process. Wages and maintenance of crew in port of refuge. Loss of freight, etc. Average Adjuster is one whose special business it is to make out and draw up statements of general average, showing the amounts
