A1 at Lloyd's
A1 at Lloyd's is an expression that denotes utmost excellence which traces its origins to Lloyd's Register of British and Foreign Shipping, a prestigious society that sets standards for ship construction. Lloyd's highest classification assigned to iron and steel ships is "100 A1", which represents the condition of the ship's hull as well as the efficiency of the equipment. "A1" is almost obsolete, since it is the highest classification for wooden sailing ships.
