Enter the length of the boat (ft) and the average wind speed (knots) into the Mooring Block Weight Calculator. The calculator will evaluate the Mooring Block Weight.

## Mooring Block Weight Formula

The following two example problems outline the steps and information needed to calculate the Mooring Block Weight.

MBW = L * 10 + WS * 5

Variables:

• MBW is the Mooring Block Weight (lbs)
• L is the length of the boat (ft)
• WS is the average wind speed (knots)

To calculate the mooring block weight, multiply the length of the boat by 10, then add this to the result of the wind speed in knots times 5.

## How to Calculate Mooring Block Weight?

The following steps outline how to calculate the Mooring Block Weight.

Example Problem #1:

1. First, determine the length of the boat (ft).
• The length of the boat (ft) is given as:: 40.
2. Next, determine the average wind speed (knots).
• The average wind speed (knots) is provided as: 10.
3. Finally, calculate the Mooring Block Weight using the equation above:

MBW = L * 10 + WS * 5

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

MBW = 40 * 10 + 10 * 5 = 450.00 (lbs)

Example Problem #2:

For this problem, the variables required are provided below:

length of the boat (ft) = 30

average wind speed (knots) = 15
