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 sus-
pended 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
