A general rule for anchoring is to use a scope ratio of 7:1 in calm conditions, which means for 20 feet of water depth, you should use 140 feet of anchor line. In rougher conditions, a scope of 10:1 may be more appropriate, requiring 200 feet of line. Always consider factors like wind, current, and type of seabed when determining the appropriate amount of anchor line.
A common rule of thumb for anchoring is to use a scope of 7:1 in calm conditions and 10:1 in rough conditions. For 20 feet of water, this means you would ideally use 140 feet of anchor line in calm conditions and up to 200 feet in rough conditions. Adjust the length based on factors such as wind, current, and the type of anchor being used. Always ensure you have enough line for effective anchoring and safety.

Assuming you are on a boat and you are using a standard sized anchor, then if the water is 20 feet deep you'd use 20 feet of line.
The correct length of an anchor line typically depends on the water depth and the type of anchoring being used. A common guideline is to use a scope ratio of 7:1, meaning for every foot of water depth, you should have seven feet of anchor line. For example, in 10 feet of water, you would need 70 feet of anchor line. However, conditions such as wind, current, and the type of seabed can also influence the appropriate length.
217 - 20 = 197 Therefore, it is 197 feet between the seabed (and anchor) and the sea level.

The length of anchor line is called "Scope" by mariners. The scope of your anchor line should be 5 to 7 times the depth of water that you're anchored in. It should never be less than 3 times the depth. In other words if you usually anchor where the water is 20 feet deep you should have a MINIMUM of 100 feet of line.
60 feet 60 Feet for short term in calm waters. The rules, 3:1 for Short term calm conditions. 5:1 For overnight and attended in normal conditions. 7:1 for overnight, unattended and potential storm conditions example, in 20 feet using 3:1 you need 60 feet... More than 7:1 offers little increase in angle.
The "rode" as it is called, is the the line (rope-with chain attached at the last five to ten feet connected to anchor) or chain (in shots-90 feet), shackles, pins and swivels. These are all instrumental in a proper anchoring of the vessel. The most agreed on method for the proper scope (amount of line) is 5' to 7' of line per foot of depth. Feet should be converted to fathoms for larger vessels and deeper depths. Most larger ships don't have more than 150 fathoms of chain.

About 4 feet deep should be good.
Using Pythagoras' theorem it is 26 feet
