The boat-deck was the topmost of the Titanic's ten decks and where her lifeboats were stored. From here, in the early morning hours of 15 April 1912, the lifeboats were lowered into the North Atlantic. Bravery, heroism, cowardice and chivalry were all displayed as the sinking drama played out.

The boat deck was constructed of teak and divided into four segregated promenades; the Officer's promenade, First Class area, Engineers', and Second Class areas. The Bridge was at the forward end of the ship, in front of the Marconi Wireless Room, quarters for the Captain and Officers, and the Wheelhouse.

The Titanic's Bridge was a partially enclosed deckhouse containing navigating equipment such as the ship's wheel and telemotor, and engine control telegraphs. With a height of 8 feet (2.4 m) and a width of 27 ft; it extended out on both sides of the vessel to enclosed cabs to aid navigation and docking.

The deck also featured first-class entrances to the Grand Staircase and Gymnasium, which were located midships, the raised roof over the First Class Lounge, and the Reading & Writing Room. At the aft end, the raised roof to the First Class Smoking Room and the relatively modest Second Class Entrance would be found. The deck also housed the boiler casings for the six boiler rooms just below the funnels all the way down to D Deck before extending further into the boiler rooms, a Compass Platform, the Reciprocating Engine Casing, Turbine Engine Casing; two Tank Rooms, the fresh water tanks, Pantry, Officer's Mess and Engineers Smoke Room. Deck chairs could also be found midships, for passengers to enjoy the view.

Sixteen lifeboats lined both sides of the ship and were stowed in chocks, rather than hanging from the falls for the davits. The davits were designed by the Welin Davit and Engineering Company Limited, of England. The boats were interrupted by a gap in the First Class area, to provide unobstructed views. Thirteen of them were full-sized wooden lifeboats, while an additional two were emergency cutters. In addition to those, four 'collapsible' Engelhardt lifeboats were provided. The boats on the starboard side were numbered 1, 3, 5, 7, 9, 11, 13 and 15. While those on the port side were numbered 2, 4, 6, 8, 10, 12, 14 and 16. As for the collapsibles, they were identified as A, B, C and D.

The emergency cutters (boats 1 & 2) were kept swung out and hanging by the davits, in case a passenger or a member of the crew happened to fall overboard or for some other type of incident, which required immediate attention. Collapsibles C and D were stowed in-board of boats 1 and 2 respectively. While the other two Collapsibles A and B were stowed on the roof of the officer's quarters, on either side of the number one funnel. When filled, the twenty lifeboats in total could hold 1,178 people. That's half of the total number of people aboard.

These collapsibles proved difficult to lower, as there were no davits on top of the officer's quarters and they weighed a considerable amount, even when empty. During the sinking, the officers had to place them on oars, so they could be lowered down to the boat deck. The boat deck was the last deck to flood, at approximately 2:05 a.m. While Collapsible B was being lowered, it suddenly capsized and subsequently floated off the ship upside down, just mere minutes before the ship slipped beneath the waves, at 2:20 a.m. — Jason Tiller
