Mooring Weight Calculator

Formula

The formula to calculate the mooring weight (W) is:

\[ W = S \times D \times K \]

Where:

\( W \) is the mooring weight (pounds).
\( S \) is the scope ratio (unitless).
\( D \) is the water depth (feet).
\( K \) is a constant multiplier, typically 1.5 for standard conditions.

Example

Let's say the scope ratio (\( S \)) is 7, the water depth (\( D \)) is 30 feet, and the constant multiplier (\( K \)) is 1.5. Using the formula:

\[ W = 7 \times 30 \times 1.5 \]

We get:

\[ W = 315 \]

So, the mooring weight (\( W \)) is 315 pounds.

What is Mooring Weight?

Mooring weight is the weight required to keep a vessel stationary when moored. It is a critical component of the mooring system, which includes the anchor, chain, rope, and the weight itself. The weight ensures that the vessel remains secure in various conditions, preventing it from drifting due to currents, wind, or waves.
