Jollen are small, lightweight boats commonly used for sailing and recreational activities. They are typically designed for one or two people and are known for their stability and ease of handling. Jollen can be made from various materials, including fiberglass and wood, and are often used in sailing competitions and training. These boats are popular in many regions, especially in Europe, where they are often associated with sailing clubs and youth programs. The term "Jolle" is derived from the Dutch word for dinghy, and similar boats can be found in other cultures, such as the Optimist and Laser classes.
