[It still bears saying. Even for people particularly good at avoiding this sort of thing. It only takes a moment during a tack or a gybe, or when the boat is rocked by a wave, or hit by a sudden gust of wind.]

The rest is basically common sense things. I really don't expect the weather to turn foul out there - it feels like it will be clear for the entire trip and I'll know if a storm approaches. But if she starts tossing and heaving, and you feel at any time there's a danger of being thrown off the craft, I have jacklines and harnesses to keep you tethered in. ... as well as lifejackets.

[... though, yeah, after that walking on water bit... would you really need one of those?]
