Bow shackles must be properly connected and secured to prevent loosening, especially in rough water
conditions. To attach a mooring line, remove the pin from the shackle and run it through the thimble of
the mooring line (left image below). Hand-tighten the shackle pin, then use a crescent wrench to tighten
the connection. Insert a cable tie into the hole on the shackle pin and run it through the shackle loop
(right image below). Pull tightly to secure, and trim the excess.

workboat, lifting rig for heavier systems, gloves, safety footwear, etc.) is essential to deploy any buoy
