Estimated as 45,000, but officers of the White Star Line say that the Titanic measured 45,328 tons. The Titanic was commanded by Captain E. J. Smith, the White Star admiral, who had previously been on the Olympic. She was 882 ½ long, or about four city blocks, and was 5000 tons bigger than a battleship.

Like her sister ship, the Olympic, the Titanic was a four-funneled vessel, and had eleven decks. The distance from the keel to the top of the funnels was 175 feet.

She had an average speed of twenty-one knots. The Titanic could accommodate 2500 passengers. The steamship was divided into numerous compartments, separated by fifteen bulkheads.

She was equipped with a gymnasium, swimming pool, hospital with operating room, and a grill and palm garden 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 ½ 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 ½ 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 ½ 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. The engine room was divided into two sections, one given to the reciprocating engines and the other to the turbines. There were two sets of the reciprocating kind, one working each of the wing propellers through a four-cylinder triple expansion, direct acting inverted engine.Each set could generate 15,000 indicated horse-power at seventy-five revolutions a minute. The Parsons type turbine takes steam from the reciprocating engines, and by developing a horse-power of 16,000 at 165 revolutions a minute works the third of the

ship's propellers, the one directly under the rudder. Of the four funnels of the vessel three were connected with the engine room, and the fourth or after funnel for ventilating the ship including the gallery. Practically all of the space on the Titanic below the upper deck was occupied by steam-generating plant, coal bunkers and propelling machinery. Eight of the fifteen water-tight compartments contained the mechanical part of the vessel. There were, for instance,twenty-four double end and five single end boilers, each 16 feet 9 inches in diameter, the larger 20 feet long and the smaller 11 feet 9 inches long. The larger boilers had six fires under each of them and the smaller three furnaces. Coal was stored in bunker space along

the side of the ship between the lower and middle decks, and was first shipped from there into bunkers running all the way across the vessel in the lowest part. From there the stokers handed it into the furnaces.One of the most interesting features of the vessel was the refrigerating plant, which comprised a huge ice-making and refrigerating machine and a number of provision rooms on the after part of the lower and orlop decks. There were separate cold rooms for beef, mutton, poultry, game, fish, vegetables, fruit, butter, bacon,cheese, flowers, mineral water, wine, spirits and champagne, all maintained at different temperatures most suitable to each. Perishable freight had a compartment of its own, also chilled by the plant.
