Plan A: Sail dead south from Yokohama, turn right past Tasmania, duck under Australia, skirt the Cape of Good Hope, pound farther south, keep the hairy Cape Horn just off to the right, then turn right again and beat a rhumb line northwest back home — all without stopping and alone.
To do this once takes religious commitment. To log it as one's eighth solo circumnavigation takes a man possessed.
Figure on a 200-day (seven-month) trip, give or take. Store plenty of food, water, grog, meds, fuel, batteries, enough for at least a two-month reserve, plus tools, a life raft, an emergency radio beacon or two, and for the dodgy ticker, nitroglycerin. And pray for luck — because there is no Plan B.
