Well known author and recognized expert in offshore safety Earl Hinz sets out the operating principles, design details and tactics of use for both sea anchors and drogues applied to sail and powerboats up to 100 feet length. A well prepared blue-water boat should be able to handle all weather that may be expected along its route without having to jury-rig a contraption of doubtful performance at the critical moment. Just as the self-steering vane and autopilot has given the offshore cruiser another crewman to steer his boat, sea anchors and drogues have given him an alternative way to handle threatening seas. Much has been learned about drag devices in the last 20 years. The level of knowledge having been raised by a greater proliferation of them, and the results achieved. The author skillfully brings the reader up to current knowledge levels. SC, 2000, 164 pgs. SW 1 lb.
