I agree, a good crew is critical for tacking in high winds. You don't want to be screaming at your crew when you are trying to get a 16 across the wind in 4 foot plus chop. Practice, practice, & practice, and it will be second nature. My suggestions, let way out on your jib in order to fall fall far enough off wind to pick up speed going into your tack & not pitchpole in the process. Sheet it in as you are beginning to turn. Let it backwind to bring the bows around, and make sure you don't bring it across until you are around. But don't let it tip you over backwards either. In other words, a crew that knows his jib, and where his weight should be at all times.
