A boat operator is advised never to take his/her boat on the water with overloaded people. Overloaded boats are likely to capsize or swamp easily and would be difficult to control. These are the safety instructions to follow before boarding a ship -:

  1. Never exceed the maximum weight or the maximum number of people mentioned on the capacity plate.
  2. In many States, overloading is a violation of rules.

On outboard boats, the capacity plate is also likely to display your boat’s recommended horsepower rating. The motor of your boat should not exceed this rating.

What is a Capacity plate?

Federal law mandates that boat less than 20 feet in length must have a capacity plate permanently attached in the steering or helm area. Boat owners and operators should be well aware of the recommended gross load capacity. He/she should also know the total weight, which can be carried safely on the hull of the vessel they are operating.

Therefore, a boat’s recommended gross load capacity includes the maximum weight of people, stores, deck padding, deck chairs, lights, fishing equipment, inboard and outboard motor assembly, steering controls and fuel system. The capacity plate also has instructions about the same number of adult people that a boat can carry.

The capacity plate similarly advised the safe restrictions of the hull’s engine power and it should not be exceeded. The calculation is particularly based on the advised gross load capacity.

How can we understand the instructions of a capacity plate?

There are mainly two essential aspects of a boat capacity plate. A capacity plate is meant to provide critical safety to the boat. Hence, the two aspects are the maximum number of people and total weight. Therefore, you can’t ignore any of the two aspects you don’t want your boat to sink. If the boat owner exceeds the maximum weight capacity, this will increase the distance between the gunnel and the waterline; therefore, the area which is called freeboard decreases. Hence, there are high chances that your boat will swamp.

What are the boats that do not require a capacity plate?

The PWC and sailboats Manufacturer does not necessarily require a Capacity plate. Also, boats that are more than 20 feet long may not need a capacity plate because the National Marine Manufacturers Association approves these boats.

What happens if the boat does not follow the Capacity Plate instructions?

You might be aware of a fatal accident when a boat 27 feet long with 17 people on board went out to watch fireworks. Despite following the maximum weight, the boat capsized because all the passengers gathered at the upper part of the deck resulting in higher gravity.

If your boat does not have a capacity plate, the U.S. Coast Guard recommends a formula:

Multiply the length of your boat to its width and divide the result by 15. You will get the maximum occupancy of your boat.
