I have nearly finished this one. You get an idea of the distances and sea room when he says he lashed the tiller in the same position for 16 days!
Sea anchors or drogues seem to be the answer to extremely crap weather.
Can't quite believe he would swim alongside his boat albeit in calm weather, I hope he had a rope around his body.
Girlfriend and I have a dream to sail around Australia in about 10 years. Not sure how realistic in a Northshore 27.
