The sword draft bird is a sailing dinghy . In the German Sailing Association it is a national unit class in which German championships are organized.
The sword draft bird (also: SZV for short) differs in its construction from the keel draft bird in that the underwater hull is equipped with a sword instead of a keel and in the lower mast height and sail area . With partially identical construction, both variants of the migratory bird each form their own classes.
Today sword migratory birds are usually designed for two sporty sailors, they are mainly built by the Mader boatyard in Bavaria and cost around 16,000 euros without sails (regatta version 18,000 euros). To date, over 4,000 boats of both types have been built.
History of origin
On the initiative of the sailing magazine Die Yacht , Ernst Lehfeld constructed a traveling dinghy in 1960 , which could also be manufactured in-house and should give a broad public access to an inexpensive sailing boat. The boat should be good-natured and stable so that it could also be used by beginners or older sailors. In order to offer young people and families an inexpensive way to go hiking, the original version also included a tent cabin. In addition to the dinghy version with a sword , there should also be a version with a ballast keel so that the migratory bird can also be used in coastal waters and to offer older sailors and families an even more secure option.
Although the migratory bird was explicitly not designed for racing sailing, a regatta scene quickly developed. Accordingly, the introduction of the spinnaker and trapeze in the 1960s was discussed, but rejected. While the sword draft bird quickly became a popular class, it took a little longer for the keel draft bird.
Differentiation from the Kielzugvogel
The construction of the sword draft bird differs from the keel draft bird in that the underwater hull is equipped with a sword instead of the ballast keel (keel plate with lead bomb ), as well as in the lower mast height and sail area . Since the keel and sword pull bird have the same body, conversion is possible in principle. To do this, the sword must be exchanged for the keel and another mast used. Some shipyards offer their hulls with the option of easy conversion. First, an application was made to the German Sailing Association for recognition of the migratory bird as a class association. However, the German Sailing Association as the responsible body rejected this and recommended the establishment of two separate class associations for sword and keel-migrating birds, which also happened in 1965. However, there is only one class regulation for both classes, so that technical changes in the regulations must be agreed by both class associations.
construction
Original construction
In order not to make the construction of the ship unnecessarily difficult, the construction of the hard chine in plywood was chosen. But in the meantime has also GRP - sandwich construction replaced the timber.
Further development
From the original traveling dinghy, the Schwertzugvogel has meanwhile become a well-constructed regatta boat. Due to its strictly regulated building regulations, the Zugvogel is a stable and safe dinghy with a high resale value even in the GRP construction . Even after a few years, the ships are still not "soft" and can still be sailed quickly and successfully .
Numerous further developments let the character of a traveling dinghy fade into the background. Examples of this are the introduction of the traveler or the elimination of stowage options in the bow in favor of floats. The latest rule change is that the upper shrouds can be adjusted using stretching so that they can now be adjusted while sailing. As before, sailing without a spinnaker and without a trapeze . Instead, on downwind courses, the foresail (genoa) is " boomed out " with a spinnaker pole , and there are riding straps for the helmsman and bowman. When racing, the crew consists of two people.
In 1978 the rig was changed, among other things by the introduction of lower shrouds. More decisive was the relocation of the attachment points of the upper shrouds on the deck further inwards so that the foresail can be brought closer and thus the properties on closewind courses are improved. Thus, old migratory birds are not comparable in terms of sailing performance with newer ones from 1978, which is also reflected in the change in the number of yard sticks.
Sailing characteristics
The migratory bird is considered to be a complex to sail, but good-natured boat that remains manageable even for a lighter crew in stronger winds thanks to the appropriate trim options . It is still considered a well-suited traveling dinghy.
If there is enough wind, both sword and keel migratory birds glide on space and downwind courses.
Sailing achievements
In the summer of 1990, Wilfried Erdmann sailed with his son's sword-drawn bird Kathena Schlei for 99 days from Goltoft on the Baltic coast of the GDR . The inner-German border , which had been closed for many years, was opened after the fall of the Wall , and Erdmann saw the introduction of the DM and the football World Cup there on July 1, 1990 . His course took him along the Baltic coast around Rügen in the Peene . From there he crossed over to the Feldberger Seenlandschaft and the Mecklenburg Lake District . From Lake Schwerin he took a truck to Wismar and across the Baltic Sea back to the Schlei . In his book My Limitless Seascape , he reports on the journey.
