slogging 

Slower windsurfing, sailboarding, or board-sailing with longer boards in a displacement or buoyancy mode and modest winds, as opposed to faster--planing or hydrodynamic lift--mode, with shorter boards at greater wind speed.

Planing is faster and gives more maneuverability, but requires a different technique from the displacement mode (which is also referred to as slogging or schlogging).

Found in wikipedia, under surfing.
