The storm was so big, and the options few, that there was no logical place to move the boats in the alloted time. The "crystal" was essentially 500 miles wide! I know lots of guys with boats down there who don't want to lose them, but there really weren't any good choices.
Let's say you could go back in time 48 hours, knowing with certainty what we know now. Where would you have gone? Corpus is 200 nm away and the marina downtown is flooded, minimal boat damage. Getting down there the last few days would not have been fun even on the ICW. They only lifted the storm warnings there early today.
