Sailboat Weathervane

The use of weathervanes dates back to ancient times when the first weathervane was used a temple in Athens. Since that time weathervanes have been produced and used in a variety of materials and portraying many different forms. One popular form is the sailboat weathervane which will discussed in further detail here.

The sailboat weathervane normally consists of a wind vane which is an unbalanced arrow shaped piece which rotates about a centre shaft. As the wind blows it rotates and aligns itself to the direction the wind is blowing at that time. Another piece is a fixed four quadrant wind direction indicator. By aligning these indicators properly, the wind vane will point to a particular quadrant so that the direction can be determined.

A very important part of most weathervane is the form which is added to the top. This gives the weathervane its distinctive look and has provided a great deal of customisation. For many years the common shape used on a weathervane was that of a rooster.

This happened due to a decree from the Pope and for hundreds of years rooster shaped weathervanes were placed on top of churches throughout Europe. The practice extended to many other structures throughout Europe and eventually followed to America.

In America many kinds of shapes were also developed for use as a topper for weathervanes. For a long time, political themes were important such as the eagle and Lady Liberty figure. During the 1800’s horses began to be used.

Since the horse represents strength, agility, and nobility these were popular items of choice. Since the direction of the wind was a vitally important factor in sailing ships, this theme was carried over by adding a sailboat shape to weathervanes.
