In the design of hoist systems, towlines, and towed bodies for variable depth sonar, it is necessary to have quantitative data on the forces acting on VDS components. These data are especially necessary in designing large VDS systems where the forces on towed bodies and in towlines may be as high as 75,000 pounds. Among the significant forces are those that are caused by vertical ship accelerations, which can be sensed by suitable accelerometers. If statistical accelerometers on destroyers are used to obtain data in the North Atlantic, a statistical presentation of the accumulated data over a years time can be made to form a reasonably accurate picture of vertical accelerations to be expected. The purpose of this technical memorandum is to describe accelerometer equipment and to explain how the data should be taken and recorded. Author
