How many people is limit to ride in a boat is there any law for it?

-Here is the formula that determines the Maximum amount of people based on a 150 lb person.



length x width divided by 15, round down. Again this is the max amount and does not take into account weather etc. You must have a pfd for all on board and a throwable device.

You can also have your voyage canceled until you correct the situation.Bigger is not the key. Modern boats will have a nameplate (usually on the stern), indicating the maximum number of passengers and weight of payload (including passengers. If stopped by the locals or the Coast Guard, they will look to that spec to determine if you are overloaded.

Irregardless of that, or if there is no plate, then they can stop you if the boat is obviously overloaded and appears unsafe.



If a boat is used to carrying paying passengers (which can even mean that they 'chipped in' to cover the gas, then the captain must have a Coast Guard Issued license and the maximum number of passengers is strictly limited to 6 - unless the vessel is 'inspected' as a commercial vessel and the maximum passenger limit is specified on the inspection certificate.
There is a difference between legally and safely. It doesn't even say which country you live in, so it's impossible to say whether there is a law.



But as master of the boat you must be able to determine how many you can carry safely, and that depends on the boat, the water, and your own skills. This is something you need to learn before you can leave the dock.
Every boat must have a plate somewhere - usually at the back where the motor is. It tells you how many people can legally get in your boat.
USA ? should be a US Coast guard plate on the boat. it tells how many persons can be on board.



a baby or a small child counts the same as an adult. ...small fishing boats.not labeled,...use common sense
It depends on the boat. The bigger the boat, the more people it can hold.
