## Boat Towing Weight Formula

The following two example problems outline the steps and information needed to calculate the Boat Towing Weight.

BTW = GVWR - TW

Variables:

- BTW is the Boat Towing Weight (lbs)
- GVWR is the GVWR (lbs)
- TW is the trailer weight (lbs)

To calculate the boat towing weight, subtract the trailer weight from the gross vehicle weight rating.

## How to Calculate Boat Towing Weight?

The following steps outline how to calculate the Boat Towing Weight.

Example Problem #1:

- First, determine the GVWR (lbs).
- The GVWR (lbs) is given as:: 1000.

- Next, determine the trailer weight (lbs).
- The trailer weight (lbs) is provided as: 300.

- Finally, calculate the Boat Towing Weight using the equation above:

BTW = GVWR – TW

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

BTW = 1000 – 300 = 700.00 (lbs)

Example Problem #2:** **

For this problem, the variables required are provided below:

GVWR (lbs) = 2000

trailer weight (lbs) = 200
