## Anchor Chain Rope Length Formula

The following two example problems outline the steps and information needed to calculate the Anchor Chain Rope Length.

ARL = WS*1.5 + BL

- Where ARL is the Anchor Chain Rope Length (m)
- WS is the wind speed (knots)
- BL is the boat length (m)

To calculate the anchor chain rope length, multiply the wind speed by 1.5, then add the boat length.

## How to Calculate Anchor Chain Rope Length?

The following example problems outline how to calculate Anchor Chain Rope Length.

Example Problem #1:

- First, determine the wind speed (knots).
- The wind speed (knots) is given as: 15.

- Next, determine the boat length (m).
- The boat length (m) is provided as: 10.

- Finally, calculate the Anchor Chain Rope Length using the equation above:

ARL = WS*1.5 + BL

The values provided above are inserted into the equation below and computed.

ARL = 15*1.5 + 10 = 32.5 (m)

Example Problem #2:** **

For this problem, the variables required are provided below:

wind speed (knots) = 20

boat length (m) = 40

Test your knowledge using the equation and check your answer with the calculator..

ARL = WS*1.5 + BL** = ?**
