What to use for Anchor Rode

There are several ways to go with Anchor rode. You can use anchor line/rope or chain. I had been for many years a fan of rope with a 20 foot length of chain from the anchor. The length of chain from the anchor protected the line from getting chafed from dragging on the sea floor as the boat would swing in the wind or change of tide. The chain would rub along the bottom to a new position instead of your bare anchor line as it bumped or snagged shells, rocks, or debris on the bay or sea floor. By using the chain off the anchor, you’ve added some weight which keeps the anchor line parallel along the bottom, making your boat or yacht anchor always bite deeper into the bottom.

As my cruising brought me to more areas, I noticed other new or old boats and yachts using all chain to anchor. That Clack-clack-clack of the chain going overboard is a unique sound, and as years went by, I recognized this sound more and more. You can also use much less anchor rode if you have all chain, and I noticed another factor in direct relationship between the two. With rode of line/rope, you move around on the anchor a lot more and also feel more movement when the wind picks up. With an all chain anchor rode, you seem to swing less and as the wind picks up, you also seem to just ease back slightly as the wind blows. It’s like slow motion.

When diving below the water, I have found a difference between the all chain anchor rode and the line/rope anchor rode. With the all chain anchor rode, you can see it go right for the bottom and then head in the direction of the boat anchor. As your boat eases back from a puff of wind, pull makes the chain lifts off the bottom. It is a lot of weight when the chain has to lift off the bottom, which in turn doesn’t let you move back too much. With line/rope anchor rode, that same puff of wind pushes your boat or yacht back quickly becuase there is no weight to the line/rope. It then pulls the chain by the anchor and sometimes gives you a jerk as it tugs on the anchor. Also when anchored and swinging in the wind, the anchor rode with line/rope takes on a full swing of the line you have out. With the all chain rode, its weight alone keeps you in a tight swing so you don’t feel the motion.

When the wind is really blowing, it is good to use all chain rode to keep that anchor on the bottom and biting. With this sort of wind you can be placing more stress on the chain links and your boat or yacht by all the jerking. This is when you should attach a line/rope right to the chain, maybe 20 feet or so and tie the line/rope to a sturdy cleat. This line/rope will now give you stretching abilities to create less strain and stress to the boat and on the chain links in particular.

Chain comes in varied sizes and tensile to match your boat or yacht needs. There are some considerations to the storage and weight of chain, but also most boats and yachts today have anchor windlass to help let out and/or bring the chain aboard. Take a look around the next time you anchor…You will see the difference.
