23.3 meter class of the DGzRS - 23,3-Meter-Klasse der DGzRS
The 23.3-meter class is a series of seven rescue cruisers (SK) of the German Society for the Rescue of Shipwrecked People (DGzRS). The ships were built between 1980 and 1991 by the Schweers shipyard in Berne-Bardenfleth and Abeking & Rasmussen in Lemwerder . The lead ship of the class was the cruiser Eiswette . Currently only one cruiser of the series is in service with the DGzRS.
The hull of these ships is made of seawater-resistant aluminum , which was built in a net frame system. It is powered by two MTU V10 diesel engines , each with 2 turbochargers and fully modulable Twin Disc MG 530M Omega gearboxes, each of which drives a propeller . The total output is 1944 hp. The cruisers are controlled from an upper, open control stand or from the lower control stand in the deckhouse . The cruiser has a daughter boat for rescuing shipwrecked people and for traveling in shallow water , which is carried in a stern tub and can automatically retract and extend. Cruiser and daughter boat are asSelf-righting constructs and erecting themselves again after capsizing . The fire extinguishing equipment includes a pump with a capacity of 380 m³ / h and a stationary, remote-controlled monitor with a throw of 90 meters. The cruiser also has a tow hook, various powerful headlights, an on-board hospital with medical equipment, living quarters for the crew, various mobile rescue equipment, mobile bilge pumps as well as extensive navigation and radio equipment. The last three ships in the class have a two-leg mast that improves visibility aft.
The first cruiser of the series was built in 1980 by the Schweers shipyard in Bardenfleth under shipyard no. 6440 and baptized on July 12, 1980 in Bremen-Vegesack with the name of the Bremen ice cream bet . At this event, donations are traditionally collected for the DGzRS. The internal name of the cruiser was KRS 12. The daughter boat was christened Mellum , an island in the Weser estuary. The internal name of the daughter boat was KRT 12.
In 1990 the Eiswette was equipped with a new daughter boat called Japsand , a sandbank in front of the Hallig Hooge . Its internal name was KRT 24. The previous daughter boat was used as an independent rescue unit under the name Kaatje .
In November 2008, the rescue cruiser was decommissioned and sold to a private company. The daughter boat was used on the Vormann Leiss (see below).
The Fritz Behrens was also built as the second unit of the class in 1981 by the "Schiffs- und Bootswerft Schweers" (shipyard no. 6442) and christened on January 23, 1981 in Vegesack . The name honors Fritz Behrens , who in his will founded the Fritz Behrens Foundation  , which made a donation to the DGzRS for the construction of a new rescue cruiser. This makes it the second DGzR ship to be baptized with this name. The DGzRS internal designation was KRS 13.
The cruiser's first daughter boat , the Anna , had the internal name KRT 13. The name of the daughter boat was the first name of Behrens' wife. This was used in 1990 by the DGzRS as an independent rescue unit under the name Umma and replaced by a new building of the same name ( Anna II, internal name KRT 23).
From June 1981 to September 1994 the Fritz Behrens was stationed in Büsum. On September 7, 1994 there was an accident in the port of Büsum ; in the process, the passenger ship First Lady collided with the stern area of the cruiser and pushed it under water. The damaged Fritz Behrens was then repaired in the shipyard. As part of this stay in the shipyard, the cruiser was extensively converted, which clearly differentiated the ship from its sister ships. The delta shape (widest part of the ship is the stern) leads to better course stability in the high seas from aft.  The first class with this new hull shape is the 23.1 meter class .
The daughter boat was so damaged after the accident that it was not worth repairing. She received a new building of the same type, which was again called Anna .
After the shipyard time she was stationed at the DGzRS station Greifswalder Oie in Mecklenburg-Western Pomerania . From February 2009 she acted as a reserve cruiser, in summer 2009 she was retired. In August 2009 it was sold to a private person.
The Minden was built in 1985 by the Abeking & Rasmussen shipyard in Lemwerder under construction number 6396. The DGzRS internal designation was KRS 16. The daughter boat of the cruiser had the internal designation KRT 16.
The cruiser was baptized at a ceremony in Lemwerder on August 3, 1985 in honor of the numerous donors in favor of the DGzRS from the state of North Rhine-Westphalia in the name of the city of Minden located there. The godmother was the wife of the then Minden mayor , Helga Röthemeier.  The daughter boat was christened Margarete at the request of an anonymous donor .
From June 1985 to May 1989 the Minden was stationed in Wilhelmshaven , in June 1989 it was relocated to List on the island of Sylt. On November 16, 2013, it was officially decommissioned and sold to a private person.
The ship was used in the Aegean Sea from March 2016 to early July 2016 to save refugees from drowning. The team consisted of voluntary sea rescue workers from the DGzRS and rescue workers from the DLRG.   As part of the temporary action, more than 1,100 people, including around 400 women and children, were freed from danger within a very short time in close cooperation with the Greek coast guard . The ship was made available free of charge by the new owner. 
The Vormann Leiss was founded in 1985 by Abeking & Rasmussen in Lemwerder under shipyard no. 6398 built. The cruiser got its name at a ceremony in Lemwerder on August 3, 1985 in honor of the Leiss family from the island of Langeoog , from whose ranks numerous rescue men had emerged in the past. The DGzRS internal designation was KRS 17. The first daughter boat was christened Erika at a donor's request and had the internal designation KRT 17.
In April 2009, the foreman Leiss took over the daughter boat Japsand (KRT 24) from the previously decommissioned Eiswette . The previous daughter boat Erika was removed from the active fleet. In February 2010 it was transferred to the sea rescue service on the Dutch Caribbean island of Saba , where it is used in the SAR service. 
From August 1985 to July 1996 the Vormann Leiss was stationed in Bremerhaven , then on the island of Nordstrand . From November 2008 it was the successor to the ice bet at the Amrum station in the Wittdün sea sign port . On May 10, 2015, the cruiser was decommissioned and replaced by the newly built Ernst Meier-Hedde in June 2015 . The cruiser was sold to a private owner in June 2015.
The Nis Randers was built in 1990 by the Schweers shipyard in Berne - Bardenfleth under shipyard no. Built in 6474. The cruiser got its name at a ceremony in Bremen as part of the celebrations for the 125th anniversary of the DGzRS on May 29, 1990 after the title character of the ballad of the same name by Otto Ernst . The DGzRS internal designation is KRS 20.
From the Nis Randers, the new automatic daughter boat recovery system will be used at the DGzRS. In addition, the Nis Randers and the following rescue cruisers of this class have an extinguishing monitor on the aft edge of the superstructure as well as a two-legged mast that enables a clear view aft.
Compared to the previously built cruisers of this class, the daughter boat was modified again; the speed could thus be increased from 17 to 20 knots with the same engine power. The daughter boat Uncle Willi des Kreuzers has the internal name KRT 20. The daughter boat was named in honor of a long-time foreman of the DGzRS station Maasholm .
From May 29, 1990 to September 2018, the Nis Randers was stationed in Maasholm on the estuary . It was replaced by the Fritz Knack , a new building in the 20-meter class, which is, however, stationed in Olpenitz .   Until January 2020 she was still used as a reserve cruiser. The ship was then sold to a private owner in Croatia and shipped from Bremerhaven to Split in June 2020 . 
The foreman Jantzen in 1990 also from the ship and shipyard Schweers at the shipyard no. 6476 built. The baptism took place on November 27, 1990, a few weeks after German reunification, in Warnemünde in memory of the pilot commander and foreman Stephan Jantzen . The DGzRS internal designation is KRS 21.
After the serious accident of Alfried Krupp , Vormann Jantzen was also partially rebuilt. The most striking feature were the now round portholes that replaced the angular window surfaces.
From November 27, 1990 to April 11, 1997, foreman Jantzen was stationed in Warnemünde and was then transferred to the DGzRS station in Darßer Ort . Since October 2003 she has been used as a reserve cruiser (e.g. as a replacement for cruisers that are in the shipyard for inspections), but also for advertising events.
The daughter boat Butscher - in Low German a "smart boy" - of the cruiser has the internal designation KRT 21. It has increased the engine power by 15 hp compared to the Nis Randers built in early 1990 .
The Hannes Glogner was built in 1991 by the Schweers ship and boatyard under construction number 6478. The cruiser was named on April 23, 1991 on the East Frisian island of Langeoog in honor of a deceased Hamburg builder who was associated with the DGzRS during his lifetime. The internal DGzRS designation of the ship is KRS 22. The daughter boat Flinthörn , named after a group of dunes on Langeoog, has the internal designation KRT 22.
After the serious accident of Alfried Krupp , the Hannes Glogner was partially rebuilt and overhauled. Among other things, the angular window surfaces were replaced by round portholes and the panes of the lower operator's platform were equipped with even stronger armored glass. The most noticeable feature of the conversion, however, was a roll bar with an associated network system above the upper control position of the rescue cruiser. This was supposed to prevent a crew member from going overboard during heavy weather trips. In 2005, however, the roll bar was dismantled again in the shipyard, as it had not proven itself.
From April 23, 1991 to January 2002, the Hannes Glogner was stationed in the protective harbor on the island of Langeoog and has since served as a reserve cruiser. It was decommissioned in July 2018.  The ship was sold to the Uruguayan Navy in July 2018 together with the also retired Hermann Helms .
