Abstract :
In former times every ship that went to sea was in danger of foundering or being driven ashore in a storm; of being destroyed by fire or disabled and lost through an accident to her machinery. She ran the risk of collision with an iceberg, a derelict or another ship, and of running ashore in darkness or thick weather.
