PCT No. PCT/US96/15478 Sec. 371 Date Mar. 20, 1998 Sec. 102(e) Date Mar. 20, 1998 PCT Filed Sep. 20, 1996 PCT Pub. No. WO97/11395 PCT Pub. Date Mar. 27, 1997An underwater cable arrangement comprises an underwater cable capable of being towed through the water, an external device for mounting on the exterior of the cable, and a coil support device disposed inside the cable for supporting a coil. In some embodiments, the coil support device and the external device have engaging portions which co-act with each other to prevent relative rotation of the coil support device and the external device about the longitudinal axis of the cable. In some embodiments, the underwater cable has a skin and the external device is positioned around the coil support device with the skin of the underwater cable between them. The coil support device and the external device have an interference fit with respect to each other to resist relative movement to the coil support device and the external device in the longitudinal direction of the cable. In some embodiments, the external device and the coil support device are fitted to each other so as to maintain a constant angle between a longitudinal axis of the cable and a longitudinal axis of the external device.
