A cryptic name to be sure, but DDDB is a fascinating collection of experiences of sailors who have resorted to sea anchors and drogues to survive extremely heavy weather encounters. It separates fact from fiction by extracting critical patterns and insights from a large number of observations - the essence of the scientific method.  It analyzes the evidence and data from more than 120 meticulously documented case histories to help you make more informed decisions when encountering heavy weather. Many types of sea anchors and drogues are covered and identified by name as they were used by monohulls, multihulls, and powered vessels. This is truly an important reference work which provides a long awaited analysis. SC, 1998, 300 pgs. SW 2.0 lbs.
