RMS Titanic due to design changes requested by Ismay and a temporary pause in work occasioned by the need to repair "Olympic", which had been in a collision in September 1911. Had "Titanic" been finished earlier, she might well have missed her collision with an iceberg. "Titanic"s sea trials began at 6 a.m. on Tuesday, 2 April 1912, just two days after her fitting out was finished and eight days before she was due to leave Southampton on her maiden voyage. The trials were delayed for a day due to bad weather, but by Monday morning it was clear and fair. Aboard
RMS Titanic the years of the two World Wars, the International Ice Patrol has worked each season since 1913. During the period there has not been a single reported loss of life or property due to collision with an iceberg in the patrol area. In 1912, the Board of Trade chartered the barque to act as a weather ship in the Grand Banks of Newfoundland, keeping a look-out for icebergs. A Marconi wireless was installed to enable her to communicate with stations on the coast of Labrador and Newfoundland. "Titanic" has gone down in history as the ship that was called unsinkable.
