Anchor Swing Circle Calculator

Formula

The formula to calculate the Swing Circle Radius (R) is:

\[ R = \sqrt{L^2 - D^2} \]

Where:

Swing Circle Radius (R): The radius of the area within which a boat or ship can move around its anchor.
Anchor Line Length (L): The length of the anchor line.
Water Depth (D): The depth of the water where the anchor is dropped.

Let's say the Anchor Line Length (L) is 50 meters and the Water Depth (D) is 30 meters. Using the formula:

\[ R = \sqrt{50^2 - 30^2} \]

We get:

\[ R \approx 40 \text{ meters} \]

So, the Swing Circle Radius is approximately 40 meters.
