That boat could probably have been a serious sea boat with adequate ballast. But that number of mistakes following each other during the build process ist alarming. Maybee the owner kept the yard too tight to do things just the neccessary little bit better? Could be possible as well... Hmm... How do things like this happen? The accident report certainly raises just as many questions as it answers. It most probably indicates sloppy management by both the yard and the owner´s supervisor.
