Abstract
A towed underwater transducer assembly includes a spherical housing (10) suspended from a towing vehicle at the end of a cable (12). The housing includes mounting brackets (26, 28) located less than one-half of the circumference of the housing apart along a meridian of the housing (10) centered in the direction of tow with a bridle cable (24) extending between the mounting brackets including a turnbuckle (32) to adjust its tension and a mechanical stop (30). A grooved pulley wheel (22) is mounted at the end of the towing cable (12) with the bridle cable (24) riding in the groove and the pulley wheel (22) free to seek a position along the bridle cable (24) such that the projected line of the tow cable (12) passes essentially through the geometric center of the spherical housing (10) thereby causing the spherical housing (10) to maintain an essentially vertical orientation irrespective of variations in the speed of tow.
