Titanic’s sea trials would begin at 0600. It was cancelled the previous day due to bad weather. The day was clear and fair for the trials. Aboard were 78 stokers, greasers, and fireman. 41 members of the crew were also aboard. Harold Bride and Jack Phillips were aboard as well both as radio operators and to make sure the equipment was ready.

Various representatives were aboard which included the following:

• Thomas Andrews and Edward Wilding of Harland and Wolff
• Harold A. Sanderson of IMM
• Francis Carruthers of the Board of Trade to certify the ship was working correctly and fit to carry passengers.

Unfortunately, due to illness neither Bruce Ismay nor Lord Pirrie could attend. The Titanic was out through a series of tests to show how she handled. These were done in Belfast Lough and in the Irish Sea. Over 12 hours the ship was driven at different speeds and her turning ability was tested. Testing on how fast Titanic could stop quickly (called a “crash stop”) was done as well. This was achieved by reversing full ahead to full astern. Titanic came to a stop in 850 yards taking approximately 3 minutes and 15 seconds. Titanic covered a distance of about 80 nautical miles (92 land miles) with an average speed of 18 knots (21 mph). Titanic reached its maximum speed of slightly under 21 knots (24 mph).

Titanic returned to Belfast at around 1900 (7 pm). Carruthers as surveyor for the Board of Trade signed the document (“Agreement and Account of Voyages and Crew”) certifying for 12 months the ship was seaworthy. Titanic would depart at 20:00 (8 pm) for Southampton. It would take 28 hours to reach her destination near midnight on 4 April 1912.

Due to delays in fitting out, repairs to Olympic and bad weather, Titanic began her sea trials on 2 April 1912. The trials began at 0600 (6 am). There were stokers, greasers and fireman along with crew members aboard. Thomas Andrews and Edward Wilding were aboard representing Harland & Wolff. Harold Sanderson represented IMM. Both Bruce Ismay and Lord Pirrie were ill and could not attend. Francis Carruthers from the Board of Trade was also present to see that the ship was fit to carry passengers. Marconi wireless operators Jack Phillips and Harold Bride were also aboard.

The sea trials took 12 hours and tested the ship’s ability to travel at different speeds, turning ability, and ability to stop quickly. Titanic was tested both in the Irish Sea and in Belfast Lough. About 80 miles were covered during the trials. The ship would return to Belfast around 1900 (7 p.). The surveyor from the Board of Trade signed papers that the ship was seaworthy for the next 12 months.

Titanic would depart an hour later to head to Southampton to take on additional crew, passengers, and supplies.
