During a vicious storm before dawn on Monday, a superyacht carrying nearly two dozen people suddenly capsized and sank within sight of a small Sicilian fishing village. A Canadian man died and several others are still missing. Here's what we know about the ship.

Who was on board? Twenty-two people were onboard the ship when it went down off the coast of Porticello, less than 20 kilometres from the Sicilian capital of Palermo. Fifteen people were rescued. A passenger ship anchored nearby, the Sir Robert Baden Powell, found some of the survivors on a life raft and took them on board before the coast guard picked them up.

Rescuers later recovered the body of the ship's cook, who was born in Canada and lived in Antigua. Several others are still missing, including one of Britain's most recognizable tech entrepreneurs, Mike Lynch, and his daughter.
