These nets have weights along the bottom edge and floats across the top, so the net will hang upright in the water. When correctly installed and aligned, it covers the perimeter of the backdown channel created by the backdown procedure, and reduces the likelihood of marine mammal entanglement. Record the same information for the purse line winch used to bring in the purse line. The system has since been developed with several new models and sizes, but the unique principle, with three rollers hauling the net simultaneously, remain the same today as when it was designed back in 1964.
