The chain and the line combine to create a rode. And when the rode is connected with an anchor, it is called the ground tackle.

Remember the rode should be in ratio with the maximum depth of the water. When the weather is really bad, or the water is rough, you will need more rode. And when the weather is calm, you will need less of it.

According to variously experienced anglers, here are three main rules of thumbs that you should take note of:

  • When you anchor your boat for a short amount of time, the weather is nice, and the water is calm. Besides, the length of the rode to the depth of water should be in the ratio of 3 to 1.
  • In case you anchor your boat for a long time, possibly overnight, the weather is nice, and the water is calm, you would need the rode with the length in the ratio of 5 to 1 with the depth of water.
  • And provided that you anchor your boat overnight when the weather seems bad with a potential of a storm ahead, you should need a rode which is 7 to 10 times longer than the depth of the water.
  • When you see that the condition of the water is getting worse, you should increase the length of the rode to prepare for worsening situations.
  • These rules of thumbs are for all types of anchors.

You would need to have more and more rode in the case of bad weather for this following reason. When the length of the anchor line or rode is increasing, the angle of pull is slightly just a small number of degrees. It is better for the line to form a horizontal line instead of a vertical line.

However, don’t just jump to the conclusion that since bigger rode is needed for a tough situation. The longer the anchor line and the rode, the safer you are in all kinds of situations.

About the depth of the water, you should calculate it at high tide. Besides, the rise of the water’s level when the storm comes as well. The depth of the water should be from the ground to the bow, not to the surface level of the water.

Here is a rule of thumb: the bigger your boat is, the longer and thicker your anchor line should be. Regardless, the line should be at least as twice as the length of your boat.

Other things that you need to consider when choosing the anchor rode is the thickness of the anchor line and the length of the chain. The thickness of the anchor line depends on the situations of the water as well as the length of the boat. The tougher the water or, the bigger the boat, and the thicker the anchor line should be. As the rules of the length of the anchor line, there are some rules of thumb for the length of the chain. It should be in the ratio of the length of the boat. Ideally, 1 foot of the boat will need 0.5 foot of the anchor chain.
