Anchoring Accessories
Collectively, the combination of anchor, rode and connector is called ground tackle. The connectors, which include swivels, shackles and thimbles, can be the weakest part of the system if not sized to the same wind loading as other parts of the ground tackle. See wind load chart in ANCHOR RODES. SHACKLES, SWIVELS & THIMBLES - Connecting the anchor to the rode is done with either a swivel or shackle.
- All- rope rode and anchor connections are typically made with a thimble, spliced onto the rope, and the shackle or swivel pinned between the rode and anchor.
- Chain and anchor connections are made with either a shackle or swivel. If a shackle is used, the shackle pin should be held in place with seizing wire. Swivels lead through the windlass gypsy easier than shackles. Chain to rope connections using a swivel is the preferable method if a windlass is on the boat. The rope to chain connection is usually made by back splicing the rope to the swivel, eliminating the thimble.
SNUBBERS - Primarily used for all chain rodes, snubbers relieve the shock loads.
- Snubbers are nylon line, of equal wind load size to the chain, with a chain hook attached.
- The length should be no less than 20, and when anchoring in rough conditions, should be longer.
- The snubber is secured independently of the rode.

TRIP-LINE - When anchoring in foul bottoms, a trip-line, used to assist in freeing the anchor, can be attached to the crown of the anchor with a small buoy floating at the surface.
- The trip-line can be ¼" nylon line and at least the length of the deepest water anticipated being anchored in.
RODE RIDER - For stormy conditions, surge, or anchoring with short scope, this device, with a sentinel attached, helps keep the rode pulling in line with the anchor and increases the anchors effectiveness.
CHAIN STOPPER - This device prevents chain from running out during the retrieval process and secures the chain once onboard.

INSTALLATION These accessories require minimal tools and skills. Toolbox: - Shackles require seizing wire and pliers.
- Splicing, a fid and some practice are all thats needed.
- Chain stoppers require a drill, bit, and nuts and bolts
