Abstract: The invention is directed to a protective rod system which is installed on the bottom of a boat by a hinge assembly which installation is about midway between the length of the boat. The protective rod system is designed to prevent manatees from being hit by the propeller of the boat to avoid injury. The protective rod system is so designed that when in a deployed system, the protection to the manatee is in place or a retracted system whereby the bottom of the boat is substantially clear of any obstruction so that the boat can navigate in shallow waters. The protective rod system extends below and beyond the rotation circle of the propeller when activated or deployed.
