How is the capacity of a boat calculated?

The calculation of a boat's capacity is based on the formula that considers both the size of the vessel and the average weight of individuals on board. By using the formula where the number of people is calculated as 150 pounds each, the vessel length is multiplied by the vessel width and then divided by 15. This approach ensures that weight distribution and safety are properly accounted for, providing a more accurate estimate of how many individuals the boat can safely accommodate.

This method takes into consideration not only the dimensions of the boat but also the typical average weight for a passenger, ensuring that capacities are practical and align with safety guidelines. In contrast, relying solely on dimensions or simplistic calculations, as suggested in other options, would not yield a reliable measure of passenger safety and comfort on the water.
