The SeaKite sail traction system is the result of many years of work and engineering. Each of the materials that make up the system have been thought through, researched and tested to optimise traction and to ensure a long life. The system is guaranteed for one year, but its life cycle is much longer. Indeed, with regular and normal use, the system will be able to pull your boat for many years. However, the wing and lines have a limited life span and should therefore be replaced after a certain number of hours.
