I can never remember whether the '100 T' is the gross weight of the ship or the weight of the cargo it can carry. Let's say it's the gross loaded weight. / / / A 100 ton floating ship displaces 100 tons of water, and the bbuoyant force on it is 100 tons.
A 100-ton floating ship displaces 100 tons of water, which is the weight of water it displaces. The buoyant force acting on the ship is also 100 tons. This buoyant force allows the ship to float by counteracting its weight.
