The most common cause of a tower damaging the gel coat is abuse. The more accessories you put on the tower (racks & boards, speakers, lights, etc) the more stress there will be on the boat. Also, never let someone climb on a wakeboard tower; not only is it very dangerous but it could cause damage to the boat's gel coat. The Monster Tower is very durable and uses Heim joints which greatly reduce the possibility of stress cracks. Monster Tower is not liable for any incidental or consequential damage caused by installation or use of the tower.
