Morphology

center + of + flotation

The phrase literally combines 'center' (middle) and 'flotation' (ability to remain afloat), so a learner who knows those words would infer it refers to a central point related to floating. However, the precise nautical meaning — a specific point on the waterline governing trimming and waterplane behaviour — is specialized and not fully predictable from the constituents, requiring domain knowledge.

Etymology

The term center of flotation is the point along a boat's waterline that acts like a balance or pivot: imagine the boat tilting forward or back and the spot where it seems to turn is the center and the water keeping it up is the flotation. That's why designers check the center of flotation when they move cargo or change a ship's load, because shifts near that point change how the boat 'leans'.
