What determines the safe capacity of a boat?

The safe capacity of a boat is primarily determined by the manufacturer's rating, which is based on various factors, including the size, weight, and design of the vessel. Each boat is engineered to carry a specific load. This rating takes into account the boat's stability, buoyancy, and structural integrity to ensure that it can safely accommodate a certain number of passengers and gear without compromising performance or safety.

Considering the other options, while the height of the boat might influence its stability or susceptibility to capsizing, it alone does not determine safe carrying capacity. The number of seats available could suggest a potential limit, but it doesn't consider the total weight distribution and dynamics. Similarly, total weight is crucial, but without the context of the manufacturer's specific ratings, it does not provide a complete picture of capacity. Therefore, the manufacturer's rating is the most comprehensive measure for ensuring safe operation.
