Once the ship was back in service her performance matched that of the Germanic, allowing the ship to make its own attempts at the.Ĭareer On 25 June 1874 she made her maiden voyage, from Liverpool to New York. In 1875, after less than a year in service, Britannic was taken out of service to be refitted with the same propeller arrangement as her sister - this work required not only removing the propeller mechanism and installing a new drive shaft but also fitting a new bed for the main engine to change its alignment. It also reduced the efficiency of the propeller in calm weather unless the angle was adjusted to be perfectly parallel to the line of the hull, making Britannic slower than her conventionally-built sistership, the Germanic.
The system proved reliable and effective at its purpose of keeping the propeller submerged in heavy weather but when set at certain angles the flexible coupling caused heavy vibration and the equipment required significantly more maintenance than a standard drive system. The shaft was raised and lowered by a small auxiliar steam engine in the ship's stern, operating rods connected to a bearing collar on the propeller shaft via a reduction gear. With the propeller fully raised the entire propeller hub and one blade could be accessed without placing the ship in -it was hoped this would reduce the cost and time required to change any broken propeller blades. In shallow water the shaft could be raised to the horizontal or slightly upwards to reduce the ship's draught and prevent a blade striking the seabed.
The Britannic's adjustable propeller was angled below the horizontal when in the lowest position, to ensure the entire propeller remained submerged. In bad weather the stern could rise enough to lift the propeller partially out of the water, reducing thrust and causing unpleasant vibration. This feature was an attempt to overcome the disadvantage of long-hulled single-screw liners, which pitched in heavy seas. This was achieved with a flexible coupling and an elongated aperture in the ship's sternpost. Drawing of Britannic 's engines.As built the Britannic incorporated a novel system which allowed the single to be raised and lowered while still connected to its shaft and without stopping the engine. Britannic 's hull was subdivided into eight by nine watertight. She was powered by inverted, supplied by Messrs of. These accommodations were divided into two main sections at either end of the ship, berths for single men in the bow and berths for single women, married couples and families in the stern.Engineering Although Britannic was rigged as a four masted, she was the first White Star ship to sport two. The steerage accommodations were located on the two lower decks and consisted of large dormitory-style cabins capable of sleeping up to 20 passengers lined against the hull, with an open space running along the centre line of the ship where passengers could congregate. Britannic 's saloon accommodations, consisting of a large, spacious dining saloon and a large number of two- and four-berth cabins were located in the centre of the ship on the main deck, being the upper of the two decks enclosed within the hull above the waterline.
As the ships were virtually larger versions of the 'Oceanic' class ships built in the previous years, their accommodations were very similar, with some variances to give each ship its own character. Contents.Accommodations The Britannic and her sister Germanic were both built to carry a total of 1,720 passengers in two classes when fully booked, 220 Saloon Class Passengers (Title of First Class at that time) and 1,500 Steerage Passengers. In 1876 it received the, both westbound and eastbound, by averaging almost 16 knots (30 km/h). Together with her sister, Britannic sailed for nearly thirty years, primarily carrying immigrant passengers on the highly trafficked to route. It was initially to be called, but, just prior to her launch, her name was changed to Britannic. It was the first of three ships of the White Star Line to sail with Britannic name.Britannic was a single-screw passenger equipped with sails built for the White Star Line's North Atlantic run.
