Hello Raymond,
I see from your profile that you are an old dinghy sailor, so from that I am assuming that you have little or no offshore sailing experience. I think that you may be thinking of the landsman's "storm", meaning " a lot of wind (undefined)", whereas a seaman defines a storm as being the next step after severe gale in the Beaufort Scale.
Repeating what I said earlier: Let's be clear what both of these techniques [fore-reaching and heaving to] are for: they make it possible to stop the boat, to wait for any reason, to think about what to do next, to cook, eat, navigate and do maintenance, in greater comfort when the sea is rough, (in up to Force 8, and possibly force 9 if the sea state is not too bad). But not, with modern boat types, as a way of surviving very heavy weather (Force 10 and above), just as a way of achieving a bit of comfort in moderately heavy weather.
I suggest that you get a copy of Heavy Weather Sailing, By Adlard Coles, updated by Peter Bruce. This will bring you to an understanding of what it is like to be at sea in a gale, or more than a gale. If you look at the photo on pp 54-55, taken in the North Atlantic in Beaufort F10 - 11, Storm - Violent Storm, you will see, I hope, that survival has nothing to do with the rig, or with heaving to.
But don't worry! Very, very few sailors experience the ultimate survival storm at sea. I haven't, after sailing the length and breadth of the Atlantic and Pacific Oceans.
