n: (GVW) a free-running propeller mounted on or near the shaftdriven main propeller of a ship or tanker ship. The Grem vane wheel turns like a windmill because of the high-speed flow of water created by the main propeller. A GVW improves efficiency and thus can increase a ships speed without additional power.
