Perhaps we got off on the wrong foot. It may have been a better conversation had you not assumed just because things were not done to your satisfaction that the Captain and crew were cold hearted. Of course they wanted to help you, they were there. Don't be such a jerk.
I don't know what safer method they employed, but it worked since you are indeed alive. Perhaps you should call out AMVER for lying about the weather in the press release? If anything, I would expect a bit of underestimation on the wave height. Sure, some might over-estimate the seas to make themselves look cool, but from a simple perspective, the waves will appear smaller from the deck of a ship that size since they are looking down on the waves.
Part of your mistake is insisting that the goals and motivations of the Captain and crew were cold and heartless because they did not decide to affect the rescue in your desired manner as opposed to a nice, "Thanks, I'm grateful, perhaps we can discuss the way the rescue went down and learn from it."
Perhaps there was a better way of doing the rescue, but it did work.
So there was somebody else standing by to save you approximately 780 miles northeast of Cape Cod? That's a nice slap in the face to somebody who came by to render assistance to the people on a boat in distress. And that's why very few would even take the time to consider your part of the story.
If it endangers the life of said crew, yep. It's just not reasonable to ask somebody to put themselves in a hazardous position to rescue you.
