BOBSled suspended by its tow cable
BOBSled suspended by its tow cable. The tow cable has one single-mode fiber-optic line for video transmission, eight conductors for system power and control, a Kevlar layer for strength, and a urethane jacket for abrasion resistance and water exclusion. This photograph shows the system with its removable nylon front bumper installed and an orange, self-contained CTD (for measuring conductivity [related to salinity], temperature, and depth) zip-tied to the framework just forward of the tow point. Excluding the front bumper, the BOBSled is 1.2 meter (4 feet) long.
