What is the purpose of a 'leash' in water sports?

The purpose of a 'leash' in water sports is fundamentally to keep the equipment connected to the user. This is particularly important in activities like surfing, paddleboarding, or kiteboarding, where the equipment can become detached and drift away if not secured. A leash ensures that the rider remains connected to their board or other equipment, promoting safety and allowing for easier retrieval if a fall occurs. By maintaining this connection, the user is also able to quickly regain control over their gear, which is crucial in dynamic water environments where conditions can change rapidly. This connection enhances the overall experience and effectiveness of the sport.
