Description
Stainless Steel Chain Stopper - 5/16" - 3/8" Chain Stoppers help prevent damage to the windlass and reduce the risk of accidental free fall of the anchor while under way. Chain Stoppers mount alone or inside most bow rollers and work with your anchor roller to take tension off your windlass.
Chain and rope should be secured at anchor when your windlass is not in use to avoid high loads the windlass was not designed for. 321820 fits chain sizes 3/16" - 1/4".
321825 fits chain sizes 5/16" - 3/8". Constructed of corrosion resistant formed 304 stainless steel.

Anchoring & Docking — frequently asked
- What size anchor do I need for my boat?
- Anchor sizing is based on boat length, weight, and windage, and every anchor maker publishes a sizing chart. When in doubt, size up — a slightly oversized anchor holds better in poor bottoms and heavy weather, and the extra weight is minor next to the risk of dragging.
- How much anchor rode (scope) should I let out?
- A common rule is 7:1 — seven feet of rode for every foot of water depth (measured from the bow roller) in settled conditions, and more when it’s rough. Adequate scope sets the anchor at a low angle so it digs in rather than pulling out.
- How do I choose the right dock fenders?
- Match fender size to your boat’s length and weight (makers provide charts), and use enough of them to spread contact along the hull. Cylindrical fenders suit most hulls; round ball fenders suit high-freeboard boats and corners. Add chafe gear where lines run over edges.
