▪ international reference line
also called  Plimsoll mark , official name  international load line 

      internationally agreed-upon reference line marking the loading limit for cargo ships. At the instigation of one of its members, Samuel Plimsoll, a merchant and shipping reformer, the British Parliament, in the Merchant Shipping Act of 1875, provided for the marking of a load line on the hull of every cargo ship, indicating the maximum depth to which the ship could be safely loaded. Application of the law to foreign ships leaving British ports led to general adoption of load-line rules by maritime countries. An International Load Line was adopted by 54 nations in 1930, and in 1968 a new line, permitting a smaller freeboard (hull above waterline) for the new, larger ships, went into effect.
