With all due respect, putting a headsail broadside to a storm force blow will usually result in the headsail blowing up or the sheet parting, perhaps even rig failure. The boat will feel like it's being stomped on, the rigging screaming for mercy, and the ride will be rough.

The trick to heaving to is to sheet as much of the leech over to the weather side as possible (I usually oversheet the jib and then tack over to starboard). This settles the boat lest you have a lazily sheeted jib not knowing whether to keep on sailing or not. The result, although fairly steady, puts the headsail up against the wind like a barn door. The catch here is that you can't use a storm jib or spitfire jib because the leech won't be able to backwind enough.

In this video, the staysail barely backwinded enough to make it work (near the center of the mast). I doubt they took off much forward way. But even with a staysail, she's not going to hold up very well to 40+ kts.

Heaving to in my book is NOT a heavy weather strategy unless it's done with a trysail. The video title is "Heavy Weather Tactics" but the only choice, apparently, is heaving to.
