“Usually when you’re steering a boat, it’s like steering a car – you aim yourself in the right direction and move the tiller a little this way or that way on keep on course. Occasionally a stronger puff of wind or a sudden wave pushes you off – like a bump in the road or a car that swings too far into your lane. But you correct. You get back on course. And you start again with the little movements. It’s easy. Anyone can do it.”
