Results of Initial Experiments to Confirm Calculations of Slack Towline Phenomena.

Abstract

USL Report no. 558 analytically describes the slack towline phenomena that occur when a body is towed under certain conditions. The test described in this memorandum was made in an attempt to induce a slack towline condition and to measure concurrently the force at the towstaff and the vertical accelerations of the fish and the ship. This experimental information, when compared to the predictions of USL Report no. 558, should serve as a check on the validity of the assumptions made in the report.
