Storm

I recently heard that M/Y Lady Haya was caught in bad storm in the Med. earlier this year... 6m+ seas, Jet Skies washed off deck, RIB washed away, major damage to fwd superstructure (due to Jetskis) as well as internal fittings and fixtures (that were not fixed down, obviously!). Question - She is a large vessel, so why so much damage, and why would the Captain put her in that position anyway (off season)? Oh, and any more info on the topic?
