CARRIED CREW OF 860

The registered tonnage was 45,000, and the displacement tonnage 66,000. She was capable of carrying 2500 passengers and the crew numbered 860.

The largest plates employed in the hull were 36 feet long, weighing 43 1/2 tons each, and the largest steel beam used was 92 feet long, the weight of this double beam being 4 tons. The rudder, which was operated electrically, weighed 100 tons, the anchors 15 1/2 tons each, the center (turbine) propeller 22 tons, and each of the two "wing" propellers 38 tons each. The after "boss-arms," from which were suspended

the three propeller shafts, tipped the scales at 73 1/2 tons, and the forward "boss-arms" at 45 tons. Each link in the anchor-chains weighed 175 pounds. There were more than 2000 side-lights and windows to light the public rooms and passenger cabins.

Nothing was left to chance in the construction of the Titanic. Three million rivets (weighing 1200 tons) held the solid plates of steel together. To insure stability in binding the heavy plates in the double bottom, half a million rivets, weighing about 270 tons, were used.

All the plating of the hulls was riveted by hydraulic power, driving seven-ton riveting machines, suspended from traveling cranes. The double bottom extended the full length of the vessel, varying from 5 feet 3 inches to 6 feet 3 inches in depth, and lent added strength to the hull.
