In this encyclopedic volume the late "Blondie" Hasler and his partner Jock McLeod, both pre-eminent in their field, have synthesized 25 years of research and development of the junk rig as adapted to western craft. It is a work which has been welcomed by the growing number of yachtsmen and designers throughout the world who already enjoy the benefits of junk rig or who wish to design one. First published in 1988, it has become the definitive work on the subject.
Practical Junk Rig: Design Aerodynamics
Practical Junk Rig examines the design and aerodynamic theory behind junk rigs and discusses how best to sail them. It is not a historical treatise but rather a detailed analysis of the intricacies of the rig, which will be of absorbing interest to both amateur owners and professional designers. It examines the rig in detail, the principles that underlie it, considers possible alternative shapes and arrangements and, of course, performance, all assisted by a wealth of detailed line illustrations.
The best is to look on your sail plan the position of the sail center of effort (CE) and to design a junk sail in order to have its CE on the vertical of the previous CE and according the position of the masts.
The key attraction of junkrig was of course its famous ease-of-handling and inherent safety. This was important as we intended to sail short-handed and, with Valerie in practical terms a novice, this choice promised a stress-free platform from which to enjoy our first experiences of cruising on our own boat. In this respect, the rig surpassed our expectations.
