No, seaplane or floatplane is the correct name. Hydroplaning iswhat Sentry described and is sometimes used in reference to boats that skim across the top of water at high speeds instead of being in it properly, such as racing boats.

At the very bottom of the disambig page on Wikipedia there is a note about hydroplanes being planes designed to land on water, but they have proper names such as seaplane and floatplane.
