Hi Utyak, Good question. I have liked heaving to in previous boat, not for survival, but just to calm things down and take a rest. We have IP380 and have only tried to heave to a few times for practice, in 20kts or so. We used a little of the jenny and sort of got it stable, but too broadside to the wind. I've read that most IPs use jenny to heave to, or use added lines to staysail (to keep to windward). But the IPs have such a nice motion in a seaway, that you may never even want to try to heave to. I just did it for fun.
