(pair’ ∂ vān,) A device that is towed through the water to maintain equipment in a certain position relative to the towing vessel. The force of the flowing water on the paravane causes the device to dive or rise or move to the side, or to maintain a particular orientation. Used, e.g., to tow a seismic streamer or sources at depth or to the side of the towing ship. See also barovane.
