The Turbinia was the first turbine steamer.The Sperry Gyro-Compass does not oscillate with the rolling of the ship, or in other words, has no heeling error. The use of the helm is greatly diminished. Records show that on one trans-Atlantic liner a saving of 24 percent in the revolutions of the steering engine, when steered by Gyro-Compass, was effected. One of the largest trans-Atlantic liners reports that but one-third of the helm is used when the ship is steered by Gyro-Compass.High Potential Test on Repeaters.This saving in the use of the steering engine gives actual proof that the ship navigated by a Gyro-Compass steers a straight line course. It further proves that the ship does not divert its slip-stream as often—the power output of the main engines is thereby reduced.Records taken on a well-known passenger liner show that in making her regular trip between New York and Jacksonville, Florida, she saved more than two hours due to steering by a Sperry Gyro-Compass. A saving of 3,410 turns of her propeller was also effected. These savings were made even with much greater than the usual draft.Records taken by means of the Sperry Recording Compass show that when the helmsman is given a certain course he can keep the ship one and one-half degrees nearer the course when steering by the Gyro-Compass than when steering by magnetic compass.The Gyro-Compass can make great savings in money both in construction and operation of the ship. These factors are perhaps trivial when compared with the safety factor introduced by the use of the Sperry Gyro-Compass.Due to the elimination of the many uncertainties of the magnetic compass, insurance companies are favorably disposed toward the use of the Sperry Gyro-Compass, which ultimately will result in a reduction of insurance rates.The use of the Sperry Gyro-Compass eliminates inaccuracies due to navigation, thereby saving time, insuring the ship, the cargo, and the lives of passengers and crew.Sperry Gyro-Compasses are operating on many of the world’s largest and fastest passenger liners and cargo ships. These ships are making savings every day of fuel used and time required to make their courses. The navigators using these compasses find that they can come very much nearer their calculated positions when steering by the Gyro-Compass. The Gyro-Compass makes the art of navigation more exact.The Sperry Gyro-Compass is the only one to pass the service tests in the world’s navies.
