WHY BOATS NEED ANCHOR CHAINS?
1. If you have a boat and you have an anchor, when throwing the anchor, this chain has enough weight to position the anchor to grab when it hits bottom. Makes life easier. The 1/4" chain will work on a larger anchor up to midsize, it is works good on 16 kayaks, 28 pontoon and 20’ boat in the intracoastal. But if your boat is above 20ft you can choose a heavier chain such as 5/16" chain.
2. Boating/anchoring in areas with rocky bottoms can cause anchors with just line to get frayed (chafing) very easily. Using an anchor chain eliminates that issue. Plus, anchor chains provide a strong connection between the anchor and line. If you boat and anchor without the chain, you may want to consider this upgrade and add the chain.
3. The purpose, according to boating magazine is: "Regardless of boat style, all anchoring systems should have a boat length of stainless-steel or galvanized chain separating the rope and the anchor. The chain prevents chafing and abrasion. Its weight also keeps the anchor’s shank horizontal, allowing the flukes to better bite the bottom." It is worth to invest a huge amount into something you knew about that this chain is a big part of construction your own anchor rode.

Note. Pay attention to the size of the chain, this 1/4" chain is not intended for large boats / anchors just pls choose right size of chain as your boats size.
