Single-handed sailor
Interesting! A free eBook with the pretentious, breath-takingly long title: "Thoughts, Tips, Techniques and Tactics for Single-handed Sailing"
It's much less outdated than typesetting or some images suggest and contains some very useful tips. Including stuff that's useful for those who sail with a less than full, or inexperienced, crew. And hé.... doesn't the average 'married couple' on a yacht qualify as 'semi-single-handed' sailing?
