摘要： A bridle block (17) for a deflector (1), the bridle block (17) including a stem (7) and a rocker arm (18) pivotably attached to each other on a pivot axis (19), the stem (7) having an attachment (20) for a towline (31) from a vessel (3), a forward portion (22) of the rocker arm (18) having an attachment (23) for fore bridle lines (15) of the deflector (1), and an aft portion (24) of the rocker arm (18) having an attachment (25) for aft bridle lines (16) of the deflector (1), and the bridle block (17) including a hydraulic cylinder (30) provided with at least one valve (35, 36), and the hydraulic cylinder (30) being attached to the stem (7) and the rocker arm (18) to hold the stem (7) and the rocker arm (18) in a chosen relative position, wherein the at least one valve (35, 36) is operated directly or indirectly by an electric control signal from a control unit (99), and the at least one valve (35, 36) takes an open position when a control signal is missing, so that there is an open fluid connection between the piston side (38) of a piston (37) and a reservoir (51) for hydraulic oil (58) or an open fluid connection between the piston-rod side (39) of the piston (37) and the reservoir (51). A method of using the bridle block (17) to passively guide a deflector (1) into a known angle of attack relative to water when the deflector (1) is being towed through the water is described as well.
