"But investigating officer Senior Constable Scott Stephens told Fairfax Media in 2008 that while he could not rule
out a pirate attack, the most likely scenario was that Mr Qualtrough had either accidentally fallen overboard
, been knocked over by the boom, or his yacht had sunk in heavy seas"
What a lame statement from a non-sailor. I doubt pirates in the Pacific and I doubt heavy sea (if there were any) could sink a 52ft. boat. Obviously it disappeared. Maybe holed or sprung a plank since he last worked on it and was inexperienced with boats.
