Someone else also commented that it won't save you if the wave is big enough. I'm not contesting that. I'm just saying that gives you your best chance.
You ignored the point that rogue waves often move in a different direction than the swell. So orienting by the swell doesn't help you with a rogue wave.
I'm not sure if I just missed it because I was busy, or if you edited the comment afterwards, but that's a good point. If the rogue wave comes from a different direction then orienting with the rest of the waves won't save you. In that case maybe if you could get some warning in time it could help. You might not be able to get to 90 degrees, but maybe you won't get caught flat out on the side either.
Still even that may not be enough to save you. The ship that went down in the North Atlantic was hit front on and sunk.
