1956-07-25 · Off Nantucket, Massachusetts, USA · Ocean liner · Italy flag
The Italian ocean liner Andrea Doria (Italian Line, 29,100 GT, 1953-built) collided with the Swedish liner Stockholm off Nantucket at 23:10 on 25 July 1956. Both vessels were operating in fog with radar; the collision resulted from misinterpretation of each other's radar-plotted courses (a classic case of what is now called the 'radar-assisted collision'). Andrea Doria took a fatal list within minutes; her innovative watertight-compartment design saved most passengers but 46 died in the initial impact + evacuation. The rescue by Ile de France + Stockholm herself was widely celebrated + broadcast — the first modern maritime disaster with substantial television + photography coverage. Andrea Doria remains one of the most photographed shipwrecks + drove the modern Traffic Separation Scheme framework.
Andrea Doria is the founding modern case for radar-assisted-collision doctrine + the modern COLREGs Rule 6 (safe speed in restricted visibility) + Rule 7 (risk of collision). Every deck officer studies the Andrea Doria + Stockholm radar plots as the reason that today's watchkeeping standards require positive confirmation of the closest-point-of-approach solution before acting.
Direct impetus for post-collision passenger-vessel safety improvements + the eventual 1966 Traffic Separation Scheme for the eastern-Atlantic approaches. Cited in IMO SOLAS revision discussions on radar collision-avoidance procedures.
