Abstract
A paravane is described that includes a float member; a baffle coupled to the float member, the baffle comprising one or more fluid ports disposed at a flow-facing side of the baffle; and a fluid source coupled to the baffle by a conduit. The fluid is a drag-reducing fluid, which may be a gas. The fluid is flowed to the flow-facing side of the baffle to reduce towing force.
