A horrible but true story analyzed by Maritime New Zealand and written up in the attached report.

Passage planning missing vital understanding of meteo resulting in being at the wrong position at the wrong time. Extreme hull flexing in very heavy sea state blew out cabin windows and a hatch resulting in an inundated yacht that would ultimately sink. Storm covers were on board but not mounted. Skipper unfortunately passed away.

A very sobering but interesting read.
