The Kielzugvogel is an open keelboat for two people with a retrievable ballast keel . In the German Sailing Association it is a national unit class in which German championships are organized.
It resembles the sword-migratory bird in terms of its construction and its shape . Despite the great constructive agreement, the keel-migratory bird and the sword-migratory bird are two different classes.
History of origin
On the initiative of the sailing magazine Die Yacht , Ernst Lehfeld constructed an inexpensive touring dinghy in 1960 , which could also be manufactured in-house. 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 sword migratory bird
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. Even after a few years the ships are still not "soft" and can still be sailed quickly and successfully , so that the migratory bird is a stable and safe dinghy with a high resale value.
Further development
In the last 50 years, this class has developed from a traveling dinghy to a well-designed regatta boat with technically balanced conditions thanks to strictly regulated building regulations. 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 headsail can be brought closer and thus the properties on closewind courses were 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. In 2001 adjustable upper shrouds were allowed and the deck shape was modified. The deck became rounder in the area of the crew to make hanging more comfortable. Since then, the upper shrouds have been allowed to be adjustable with a tackle and can thus also be adjusted while sailing in order to be able to adapt the trim to the current wind conditions at short notice. This means that the mast halyard can also be changed between the cross and the downwind course.
To date, over 4000 boats have been built in both variants.
Sailing characteristics
Despite its good nature, the migratory bird is a complex boat to sail, even for lighter crews, as a multitude of trim options allow the rig to be adjusted according to requirements. If there is enough wind, both sword and keel migratory birds glide on space and downwind courses. It is still considered a well-suited traveling dinghy.
Regattas in the Kielzugvogel
Regattas have always been sailed with the Kielzugvogel. International German Championships in the Kielzugvogel class have been held since 1966. Most of the ranked regattas are held in Germany, with the focus on the west and south of the country.
