Lusitania did not carry enough lifeboats for all her passengers, officers and crew on board at the time of her maiden voyage (carrying four lifeboats fewer than Titanic would carry in 1912). This was a common practice for large passenger ships at the time, since the belief was that in busy shipping lanes help would always be nearby and the few boats available would be adequate to ferry all aboard to rescue ships before a sinking. After the Titanic sank, Lusitania and Mauretania were equipped with an additional six clinker-built wooden boats under davits, making for a total of 22 boats rigged in davits. The rest of their lifeboat accommodations were supplemented with 26 collapsible lifeboats, 18 stored directly beneath the regular lifeboats and eight on the after deck. The collapsibles were built with hollow wooden bottoms and canvas sides, and needed assembly in the event they had to be used.
This contrasted with Olympic and Britannic which received a full complement of lifeboats all rigged under davits. This difference would have been a major contributor to the high loss of life involved with Lusitania's sinking, since there was not sufficient time to assemble collapsible boats or life-rafts, had it not been for the fact that the ship's severe listing made it impossible for lifeboats on the port side of the vessel to be lowered, and the rapidity of the sinking did not allow the remaining lifeboats that could be directly lowered (as these were rigged under davits) to be filled and launched with passengers. When Britannic, working as a hospital ship during World War I, sank in 1916 after hitting a mine in the Kea channel the already davited boats were swiftly lowered saving nearly all on board, but the ship took nearly three times as long to sink as Lusitania and thus the crew had more time to evacuate passengers. Lusitania, commanded by Commodore James Watt, moored at the Liverpool landing stage for her maiden voyage at 4:30 p.m. on Saturday 7 September 1907 as the onetime Blue Riband holder RMS Lucania vacated the pier. At the time Lusitania was the largest ocean liner in service and would continue to be until the introduction of Mauretania in November that year. A crowd of 200,000 people gathered to see her departure at 9:00 p.m. for Queenstown (renamed Cobh in 1920), where she was to take on more passengers. She anchored again at Roche's Point, off Queenstown, at 9:20 a.m. the following morning, where she was shortly joined by Lucania, which she had passed in the night, and 120 passengers were brought out to the ship by tender bringing her total of passengers to 2,320.
