Ernst August (ship)
From Wikipedia, the free encyclopedia
Ernst August was a wooden paddle steamer and corvette in the navy of the German Confederation, named after Ernest Augustus, King of Hanover.
She had a 580 tonne displacement and was 49.21 m long along the waterline and 55.47 m long in total. At her widest point she was 9.72 m and across her wheel arches she was 17.1 m wide. Her maximum draught was 3.96 m and her propulsion were two paddle wheels driven by two horizontal single-cylinder reciprocating steam engines manufactured by Miller Ravenhill, a London firm. The engine produced about 950 PSi and gave her a speed of 9 knots. Each wheel had twelve blades and a diameter of 5.79 m. The engines supplied three boilers generating around 1 atm steam pressure, housed with the engines themselves in a 16.15 m long engine room. She carried 200 tonnes of coal to power the engines, but was also rigged as a two-masted schooner. Her armament was six 68-pounder guns and her crew was five officers and 145 NCOs and men.[1] Großherzog von Oldenburg and Frankfurt were built to the same design.
