Blondie Hasler died after completion of the present work but before its publication. The name Hasler is readily associated with a number of marine projects of which perhaps the most significant was the development of wind vane steering for yachts. However, it may be that his most enduring contribution will be seen to be the adaptation of the principles underlying the traditional Chinese rig to western sailing craft. He devoted his last twenty years to it.
Blondie was of course responsible for the first singlehanded transatlantic race in 1960, and shortly before it he altered the rig of his modified folkboat Jester from the experimental Lapwing to a single Chinese lugsail slung on an unstayed mast. The boat has used the same rig ever since on her many long voyages, which include thirteen transatlantic passages.
With his coauthor Jock McLeod Blondie designed junk rigs for a number of vessels and, in addition to their own considerable experience, was able to profit by the seagoing experience of others such as Bill King whose junk-rigged Galway Blazer II completed a circumnavigation in 1973. This book is the result of all that work. But it is more.
There appears to be no comprehensive Chinese text on the rig and although a number of Western sources describe in detail the rigging of contemporary Chinese vessels, there is nothing that tells you how to design junk rigs or how to sail them. Neither is there any work on the geometry and aerodynamic theory that lie behind them. Practical Junk Rig admirably fills that need. It is both a handbook for the mariner and a work of reference for anyone who wants to study in detail this most appealing and seamanlike of rigs.
