Stability of towfish as sonar platforms and benefits of the two-part tow / J.M. Preston.: DR52-11/7-1989E-PDF
"Stability is a very important characteristic of the vessel or body on which a sonar is mounted. With normal tow configurations, stability requirements are often not met by a towfish in moderate sea states, particularly with short cable lengths. The trial described here demonstrates that the two-part tow, which uses a down weight and a neutrally buoyant towfish, significantly reduces towfish motion. In particular the two-part tow effectively suppressed pitch and accelerations. However towfish yaw, which was shown to be caused by lateral motions of the ship's stern, was still significant, and yaw is particularly important to sonar image quality."--abstract (page iii).
