Do not tow more than two persons at one time on a tow tower. The tow tower should be used only for water skis, wakeboards, or recreational towables and not for parasailing, kite flying or towing other boats. Do not add any attachments that are not installed by MasterCraft. Do not climb on, sit on, stand on, jump off or dive off the tower. Never allow passengers to sit behind the tow rope attachment point. Never allow loose tow rope ends to dangle. Always be certain that all bolts are in place and tight before and during use. When the tower is up, watch for low obstacles such as tree limbs, bridges or power lines.
