It is not a boat's "weight"
It's correct to say that the boats weight is equal to it's displacement.

Displacement can be taken as either the volume or the weight of the water the hull displaces. The weight of the water displaced is always equal to the weight of the vessel. The volume depends on the mass of the water which in turn depends on temp and salinity. But the weights are always the same.
