The 20-meter class is currently the smallest class of rescue cruisers (SK) of the German Society for the Rescue of Shipwrecked People (DGzRS). Between 2008 and 2018 six ships were built by the Fassmer shipyard in Berne . As with the 23.3 meter class , the type ship of this class is called Eiswette .
properties
The requirements for these units are specifically in the coastal area with shallow water depths. Compared to other cruisers, this class has a significantly lower draft , which was primarily achieved through weight savings. A typical DGzRS daughter boat was dispensed with and instead a rigid inflatable boat was integrated into the stern tub as a work boat . This is used to assist with operations or to navigate extreme shallow water areas. In addition, living quarters for the crew were dispensed with. She lives in the station building and can occupy the cruiser at short notice in the event of an emergency.
The rarely used external control station was omitted from the fifth cruiser in the series (Berthold Beitz) in favor of an optimized bridge and only serves as a observation deck and lookout during search trips.
Furthermore, an electrical on- board network was implemented for the first time using a data bus system . This is a special line system for the exchange of data and energy between control elements and electrical systems, as happens in a computer, but also in airplanes and, increasingly, in complex machines and modern motor vehicles. In addition to the increased operational safety, this leads to a significant weight saving.
The hull was built using the tried and tested mesh frame construction made of seawater-resistant aluminum . The shape was adopted and optimized from the earlier 19-meter class . Like all DGzRS units, this cruiser is also built as a self-erecting device. For the first time, a sea rescue cruiser was subjected to a capsize test with the Eiswette .
The cruiser is powered by a diesel engine (Caterpillar C 32 V12, 1,232 kW / 1,675 PS at 2300 rpm). This is used exclusively for driving . Another diesel engine (Steyr MO 166, 120 kW / 163 PS at 2800 rpm) serves as an auxiliary and emergency drive. In addition, a bow thruster ensures improved maneuverability.
The work boat on the first four cruisers is designed as a rigid inflatable boat and is also powered by a diesel engine (Steyr MO 164, 120 kW / 163 PS) via a jet drive. With this it reaches a speed of 30 knots (approx. 55 km / h). Starting with the fifth cruiser in the series, a modified Arctic P17 workboat made of all-plastic HDPE will be used, which is significantly more spacious with similar dimensions. The 700 kg Rigid Buoyant Boat (RBB) is 500 kg lighter than its predecessor and uses a gasoline-powered 70 HP outboard motor . The simplified recovery device also saves a further 250 kg; this relief of the stern has a positive effect on the cruiser's handling characteristics.
The cruiser's further equipment includes a tow hook, a fire pump with an output of 140 m³ / h, searchlights , medical and fire-fighting equipment, mobile rescue equipment and bilge pumps as well as the latest radio and navigation technology . The range is up to 820 nautical miles. From the fifth ship a fire monitor is installed on the forecastle.
Like all SK of the DGzRS, the 'little ones' are permanently manned by a professional crew, so that the boats are always ready to go. During the 14-day operational readiness of a crew , they are accommodated on land in the station building. Due to the space available on board, a living area, as is common with the 'big ones', was dispensed with.
The ships
Ice bet
The cruiser was launched in 2008 under shipyard no. Built in 2090. The DGzRS internal designation of the cruiser is SK 30 and the workboat TB 34 . After the first rescue cruiser called Eiswette was decommissioned at the end of 2008, SK 30 took over this traditional name in order to document the longstanding association of the Bremer Eiswette with the DGzRS. Accordingly, he was baptized at the ice bet on January 6, 2009 in Bremen. The naming of the work boat novice was also chosen on the basis of the Eiswettbrauch. Novices are the new members of the ice betting community.
The cruiser has been stationed on the North Beach peninsula since November 22, 2008 . The official commissioning took place on March 11, 2009 in the port of Strucklahnungshörn on Nordstrand in the presence of the Schleswig-Holstein Prime Minister Peter Harry Carstensen .
Eugene
The Eugen was built in 2008/2009 under shipyard no. Built in 2091. The DGzRS internal designation of the cruiser is SK 31 and the workboat TB 33 . On 25 April 2009, the rescue vessel was in the harbor of Freest the name Eugene baptized. The work boat was named Hubertus . With the naming, the DGzRS pays tribute to the generous commitment of a sponsor who provided substantial financial support for the construction of the rescue units.
From February 6, 2009 to November 28, 2017, the cruiser was stationed on Greifswalder Oie . There it was replaced by the identical cruiser Berthold Beitz , which was commissioned in December 2017 . He has been stationed on Norderney since January 9, 2018 and has replaced Bernhard Gruben there .
Theodor Storm
The Theodor Storm was built in 2010 under shipyard no. Built in 4090. The DGzRS internal designation is SK 33 and that of the workboat TB 37 . On August 13, 2011, the ship was christened by Sandra Carstensen, the wife of the Schleswig-Holstein Prime Minister Peter Harry Carstensen in Büsum in the name of the writer Theodor Storm . The work boat was named Nis Puk from a fairy tale character who is mainly known in the German-Danish border region.
The Theodor Storm has been stationed in Büsum since mid-January 2011 .
Pidder Lüng
The Pidder Lüng was laid down under the internal designation SK 34 as the fourth cruiser of the class in September 2012 in Berne. On September 16, 2013, the cruiser was launched for the first time. After testing on the Weser and North Sea, the flag change at the DGzRS headquarters in Bremen took place on October 28, 2013. Trial operation began on November 1, 2013 at the List station on Sylt , and the cruiser was put into service on November 16, 2013.
In order to support the financing of the cruiser, a fundraising competition was launched for the first time under the slogan “Thatched roof against Reeperbahn”. The participants could donate for a name reference for Sylt or Hamburg , Sylt won.
The christening took place on December 14, 2013 in List on Sylt. The name of the rescue cruiser comes from the ballad of the same name by Detlev von Liliencron (1844–1909) about the Sylt fisherman Pidder Lüng . The work boat is named after the Hamburg main church St. Michaelis - in Hamburg vernacular "Michel". It has the internal designation TB 38 .
The Pidder Lüng has been stationed in List (Sylt) since November 1, 2013. A different color scheme has been tested on the cruisers since July 2018. Daylight red adhesive films are used on the roof and as a "belly band".
Berthold Beitz
On November 25, 2016, the cruiser with hull number 7020 was laid down at the Fassmer shipyard in Bardenfleth . At the beginning of April 2017, the shell was completed and was brought to Motzen by road . After the interior work, the test drives on the Weser and Outer Weser began on November 14, 2017 . The cruiser has been stationed on Greifswalder Oie since December 13, 2017 and replaced the cruiser Eugen there.
The ship was christened on December 15, 2017 in Greifswald in the name of the long-term chairman of the Board of Trustees of the Alfried Krupp von Bohlen und Halbach Foundation , which significantly financed the construction. The work boat bears the name of his wife Else. The internal designation of the cruiser is SK 38, that of the workboat TB 42.
Fritz Knack

The ship was laid down on March 24, 2017 with the hull number 7021 in Bardenfleth. The workboat bears the name Ingeborg and the internal name TB 43 . Testing on the Weser and Outer Weser began in September 2018. Since November 1, 2018, the ship has been based at the new Olpenitz station and replaces the Nis Randers at Maasholm station .
