When does the helmsman stop turning? The rest is fine.
I like to use the wind vane, rather than the wind direction instrument, to know when to stop my turn. I steer the boat just past my boat's closehauled position on the vane's index, because the tailer usually has to grind the jibsheet in the last little bit with the winch. By doing so, the jib is slightly more powerful, and the boat accelerates out of the tack better. As the tailer grinds in the jibsheet, I steer the boat up to closehauled.
