What is Boat Capacity?

Boat capacity refers to the maximum number of people, total weight, and engine power that a boat can safely accommodate. This information is crucial for maintaining safety on the water and complying with boating regulations. Capacity limits are typically determined by boat manufacturers and are often displayed on a capacity plate near the helm. For boats without a capacity plate, boaters can use formulas to estimate these limits based on the vessel's dimensions.

How to Use the Boat Capacity Calculator

Step 1: Enter the boat length

Input your boat's length in feet. This measurement should be taken from the bow (front) to the stern (back) of your vessel. Be as accurate as possible, as this will directly affect the calculation results.

Step 2: Input the boat width

Enter your boat's width (also known as beam) in feet. Measure this at the widest point of your boat. Again, accuracy is important for reliable results.

Step 3: Specify the average person weight

The calculator defaults to 150 pounds per person, which is a common standard. However, you can adjust this value if you expect your passengers to be heavier or lighter on average.

Step 4: Click "Calculate Capacity"

After entering all the required information, click the "Calculate Capacity" button. The calculator will process your inputs and display the results.

Step 5: Review the results

The calculator will provide you with three key pieces of information:

• Maximum Person Capacity: The number of people your boat can safely carry.
• Maximum Weight Capacity: The total weight your boat can safely hold, including people and gear.
• Maximum Horsepower: The recommended maximum engine power for your boat.

Step 6: Read the explanation

Below the results, you'll find an explanation of how the calculations were made. This information helps you understand the basis for the capacity recommendations.

Step 7: Consider safety factors

Remember that these calculations are estimates. Always err on the side of caution, especially in rough weather conditions. It's crucial to distribute weight evenly and never exceed your boat's actual capacity plate limits if one is present.
