"I have heard initial reports that the ship was heading into rough weather under full sail. Speculation or fact, I can't say."

Microbursts are extremely powerful despite their short existence, and they can take down an airliner.

I don't know much about boats, but "under full sail" and "under sail" aren't necessarily the same thing. Sailboats operate under sail, and in storm conditions I think they take down a lot of the sail and just leave a small one (or ones) to keep the boat going in the desired direction. Without (sail) power, they are just adrift.
