    A new type of drogue called a series drogue has been developed as part of this research program. The objective of these tests was to measure the drag characteristics of a typical series drogue and to investigate the handling characteristics during deployment and retrieval.

        The drogue which was tested is described by Figures 16, 17 and 18. It consisted of ninety 5-inch diameter conical elements spliced into 150 feet of line. A 35-lb cylindrical weight was attached to the end to keep the drogue submerged. The drogue was attached to the boat with 80 feet of line making the length of the entire assembly 230 feet.
