Towing of instrumented cables and platforms is becoming an increasingly important method of collecting oceanographic data. To obtain greater precision of the measurements, the instruments must be decoupled from the pitch and heave motions of the towing vessel. This paper discusses a launch/recovery, motion-compensation system based on an articularing crane that serves to overboard and retrieve a variety of depressor types and also serves as the two point for compensated and uncompensated tow. The passive compensating boom will provide nearly constant tesnion in the tow cable, thereby enabling the towed body to 'fly' at a constant depth. A motion-compensation system of this type looks most promising not only in providing the means of uncoupling from the towing vessel's motion, but also in handling the towed system. (Wassmann)
