USL Report No. 558 examines the possibility of a towline going slack, which can result from the inability of a VDS towed body to accelerate downward at as high a rate as the fantail of a ship. The report also examines the high cable tensions which can result from the sudden restoration of towline tension at some time after the slackening. The likelihood of occurrence of a slack line is a function of the ratio of fish weight to fish mass. This memorandum demonstrates the need for combining the 'G factor' characteristic and the mass of a towed body in determining the likelihood of the loss of a towed body under specific conditions.
