SMS Pommerania was a paddle steamer originally built for use as a packet ship but was acquired by the North German Federal Navy in 1870 during the Franco-Prussian War. Commissioned too late to see service during the conflict, she was initially used to conduct fishery surveys that were later used as the basis for the German Fisheries Act in 1874. Pommerania went to the Mediterranean Sea in 1876 in response to the murder of a German diplomat and remained in the region to observe the Russo-Turkish War of 1877–1878. After returning to Germany in 1879, she spent much of the 1880s either operating as a fishery protection vessel or conducting surveys of the German coastline. Decommissioned in 1889, she was struck from the naval register in 1890, sold in 1892, and was converted into a sailing schooner. She was renamed Adler, but was lost with all hands on her first voyage as a merchant ship in January 1894.
Characteristics
The early history of Pommerania is poorly recorded, as few official records concerning her construction have survived. The ship was originally built for the packet service between Stettin and Stockholm; her design was prepared by the Prussian Navy's chief designer, Carl Elbertzhagen, in 1863. The navy also assumed the cost of construction; the naval historians Hans Hildebrand, Albert Röhr, and Hans-Otto Steinmetz state that the fact that the Prussian Navy bore the cost of construction and designed the ship suggests that the naval command wanted to have access to a steamship that it could use as needed.[1][2] She was requisitioned during the Franco-Prussian War in 1870 as what was by then the North German Federal Navy sought to acquire ships with which it could defend the North German Confederation's coast in the North and Baltic Seas. Pommerania was among four merchant ships purchased by the navy, along with the paddle steamer Falke and the HAPAG passenger liners Cuxhaven and Helgoland.[3]
Pommerania was 50.5 m (165 ft 8 in) long at the waterline and 55.2 m (181 ft 1 in) long overall. She had a beam of 6.9 m (22 ft 8 in) over her hull and 9.7 m (31 ft 10 in) over the boxes for her paddle wheels. Her draft was 2.35 m (7 ft 9 in). As designed, she displaced 391 metric tons (385 long tons) and at full load, this increased to 460 t (450 long tons). Her iron hull was constructed with transverse frames; the number of watertight compartments has not survived. Steering was controlled with a single rudder.[1]
The ship was a good sea boat and was very maneuverable, but she handled poorly in severe weather. She was difficult to control and lost considerable speed in a head sea, and she tended to ship large quantities of water forward. To supplement her steam engine, she carried a schooner rig, but it contributed little to her performance. These problems were typical of paddle steamers. The ship had a crew of four officers and sixty-one enlisted men. She carried four smaller boats of unrecorded type.[1]
Pommerania's propulsion system consisted of one vertical, oscillating 2-cylinder marine steam engine that drove a pair of paddle wheels located amidships. The wheels were 6.55 m (21 ft 6 in) in diameter, with ten paddles each. Steam for the engine was provided by two coal-fired trunk boilers. The engine and boilers were placed in a combined engine/boiler room, and the boilers were each ducted into their own funnel. The system was rated at 300 nominal horsepower. In service, she was capable of 700 metric horsepower (690 ihp) and a top speed of 14.5 knots (26.9 km/h; 16.7 mph). She could carry up to 75 t (74 long tons) of coal, which allowed a cruising radius of 300 nautical miles (560 km; 350 mi) at a speed of 14 knots (26 km/h; 16 mph).[1]
The ship was armed with a pair of 8 cm (3.1 in) 23-caliber (cal.) breechloading hoop guns that were supplied with 120 shells. Later in her career, these were replaced with a pair of 8.7 cm (3.4 in) 24-cal. hoop guns. She also received four 3.7 cm (1.5 in) Hotchkiss revolver cannon in 1880.[1]
