An elongate towed acoustic array is improved by the inclusion of a specifically configured tensile load bearing strength member disposed within a hose-shaped sheath. The member has a plurality of longitudinally extending high strength cords formed of braids or strands of high tensile strength fibers. The cords are held in a longitudinal juxtaposed relationship by a transverse weave to define a hollow interior for non-compressively containing sensor elements. Thusly configured, the strength member possess a softness and flexibility that does not create damage inducing crimps while not overly interfering with the sensors acoustic sensing capabilities. The hose-shaped sheath contains the tubular-shaped strength member in a non-compressive relationship to reduce the problems normally associated with flow noise. The cords are braided together in an eye-splice where they are wrapped about towing pins so that the cords tensile strength is not compromised at the point of attachment. Optionally, a twill weave is used to hold the longitudinal cords in their juxtaposed relationship to assure softness and flexibility for the wall of the strength member.
