Titanic had 29 huge boilers that comprised 159 furnaces. These furnaces had a heating surface of approximately 144,142 sq.ft. There were 24 double-ended boilers and 5 single-ended boilers.
When completed, Titanic was the largest man-made moveable object in the world.
Titanic was fitted with a set of steam whistles on each of the 4 funnels. Though all 4 sets appeared to be genuine, in fact only those mounted on the Nos 1 and 2 Funnels were operational; the ones mounted on the Nos 3 and 4 Funnels were dummies. The sound of Titanic’s whistles could be heard up to 8 miles away.
There were 13 honeymooning couples on board.
The iceberg was about 100ft tall. At 32°F, the iceberg was warmer than the water Titanic passengers fell into that night. The ocean waters were 28°F below freezing point but not frozen because of the water’s salt content.
Lifeboat No.7 was the first to be launched at 12.40 a.m. (65 minutes after hitting the iceberg). It carried 28 people yet was rated to hold 65.
