Title: "SEA - OR DRAG-ANCHOR" ABSTRACT A sea anchor or drogue has a body including a front section (11) tapering forwardly to a nose with means (25) for attaching a hawser (26) by which the device may be towed by a vessel, and a rear section (12) tapered or diminished towards the rear and hollowed or concaved from the front, the front section of the body being formed with longitudinal channels (22) leading into the hollowed back section (12). When towed, water driven through the channels (22) into the back section (12) is ejected outwardly and forwardly from the periphery of the back section, imparting considerable drag. For stability, the back section (12) has small relief ports (24) and stabilizer fins (15). The body (10) may also be formed with longitudinal flow-through tubes (19) with inlets (20) in the front section (10) and restricted outlets (21) from the back section (12).
