1) A mooring operation describes attaching a vessel to a stationary object using various equipment like anchors, ropes, and winches that could break and snap back with force. 2) Proper safety procedures during mooring include only having essential crew present, paying attention to weather, and informing crew of snap back zones to avoid injury from parted lines. 3) It is important for vessels to clearly mark snap back zones to prevent deaths from ropes snapping back with force if they break during mooring operations.
