A big one with lots of freeboard and either inboard engines or an outboard platform like the offshore center-console fishing boats have. How they calculate the safe capacity of a boat is simple: they put the boat in the water and add weight until water comes in to determine the displacement weight. Then they divide by five to reach the safe weight capacity. Therefore it stands to reason that the farther you can push the boat into the water before it sinks, the more safe weight it can carry.
The maximum number of persons and weight the boat should carry. (BE-13)
The maximum number of persons and weight the boat should carry
should be about 1450lbs
1980 campion 18 ft
By keeping the water out. Don't exceed the boat's weight capacity and don't allow any holes in the boat.
The maximum weight and/or number of people the boat can carry safely.
A boat's capacity plate contains several pieces of important information. First, it states the maximum passenger weight that can be carried in pounds. Second, it shows the maximum weight the boat can carry of any sort (people, boat accessories and gear). Third, it states the highest horsepower load the boat can have.
the capacity of a boat depends on what type of boat it is and how big it is

No simple formula. When you add 100 kg to the boat, it displaces 100kg, ~ 100l water. You must then calculate how much lower the boat gets in the water, to displace that water. It would be easier, if the boat had vertical sides, like a barrel or a box, otherwise you need to do integration (calculus). If the boat is not rocking, and the water is perfectly still, you can put people into the boat, until the weight of the people equals the weight of the water displaced when the edge of the boat is at the edge of the water. But in real life, you must account for waves, wind etc. Then there is seating capacity, toilets, food etc, if we are talking about a liner or ferry.
