The forward-most section of a vessel's hull below the waterline, specifically the shape and angle at which the bow parts the water. A fine or sharp entrance creates less wave resistance and allows for higher speeds, while a fuller entrance provides more buoyancy and cargo capacity forward. Naval architects carefully design this geometry to optimize hydrodynamic efficiency.
