  A new model other than the classical ones given by Airy, Stokes and Gerstner
for the ocean surface wave is constructed. It leads to new understandings for
the wave mechanisms: (1) A wave with bigger amplitude or smaller steepness
travels faster; (2) The wave breaks when the front angle is bigger than 46.3
degree; (3) The magnitude of the wave drift should be smaller than that of the
known Stokes drift.
