Excellent account of Knox-Johnston's world-first, non-stop, unassisted circumnavigation. This book may be a bit too technical for non-sailors, but experienced sailors will smile in commiseration at the troubles he overcame. His frustration at, for example, winds blowing directly from the direction he wanted to travel is well known to those who have tried to cover 100 miles or more under sail at sea. Likewise his high spirits when winds and sea state cooperated.
One of the things he said made me feel vindicated about a position I have taken regarding life preservers (PFD's) while sailing alone. In short, I don't wear one. As Knox-Johnston says, if you go overboard while 50 miles (or more) off shore, you're done, so why bother with the bulky, uncomfortable thing? The right approach is to take steps to insure you do not go overboard, very much as one would take steps to avoid falling off a 100 story building. When sailing alone, overboard means death, so behave accordingly.
In general, I ended up liking his bluff, no-nonsense, competence and I admire the courage it took, in 1968 with zero electronics, to sail around the world, non-stop and alone. He is a very different man than his chief competitor, Bernard Moitessier, but both were amazing sailors.
