If a boat weighs more than the water it displaces, what will happen?

When a boat weighs more than the water it displaces, it cannot displace enough water to support its weight, leading to the consequence of sinking. This principle is rooted in Archimedes' principle, which states that an object submerged in a fluid will displace an amount of fluid equal to its own weight. For a boat to float, it must effectively displace a volume of water that weighs more than its own weight. If the boat's weight exceeds the weight of the water displaced, it will not achieve the necessary buoyancy, resulting in the boat sinking.

The other possible outcomes, such as floating, capsizing, or drifting, rely on buoyancy, stability, and external conditions, which are not applicable when a vessel is overloaded beyond its displacement limits. The fundamental relationship between weight and displacement directly leads to the conclusion that a boat that is heavier than the water it displaces will indeed sink.
