Morphology
The phrase is compositionally built from 'center' (middle point) and 'buoyancy' (tendency to remain afloat), so its meaning — the central point related to the buoyant force/submerged part — is directly derivable from the constituents. Although it's a technical term, the structure follows standard noun + of + noun composition found across languages, so a B1 learner who knows the words would likely understand it.
Etymology
Center of buoyancy comes from the idea of one point under a boat where the water's upward push, called buoyancy, acts. Imagine the underwater shape has a single balancing point — the center — where that push works, and that point shows whether the ship will float straight and stay 'upright'.
