Length: 36.5m. Draught: 2.6m. Speed: 25kn.
These are just a few prominent technical specifications of the search and rescue vessel "Harro Koebke”, built for the German Maritime Search and Rescue Association (German: Deutsche Gesellschaft zur Rettung Schiffbrüchiger, DGzRS); handed over and named in the German Baltic port of Sassnitz on the island of Rügen. The SAR Association’s demands concerning the strength and safety of their ships surpass the usual shipbuilding requirements by far. This applies to the requested double shell plating, for example, which ensures buoyancy even in the case of an underwater damage. A seawater-resistant aluminium alloy was used for decks and superstructure. The tight net-frame construction, consisting of longitudinal and transverse frames helped reduce the weight of the aluminium structure as far as possible, while at the same time optimising its rigidity.
