The start of Titanic's career was running on a tight schedule. She had to make her Maiden Voyage very soon, but the bad weather had caused the sea trials, planned for April first, to be rescheduled to April 4th. This meant that her delivery trip was postponed too.
On returning to Belfast at about 7 P.M. after the sea trials, the surveyor signed an "Agreement and Account of Voyages and Crew", valid for twelve months, which declared the ship seaworthy. An hour later, Titanic left Belfast again—as it turned out, for the last time—to head to Southampton, a voyage of about 570 nautical miles (660 mi; 1,060 km). After a journey lasting about 28 hours she arrived about midnight on 4 April and was towed to the port's Berth 44, ready for the arrival of her passengers and the remainder of her crew.
