The preliminary report seems to suggest that the yacht's construction was at fault.
I don't understand the following:
"The study indicated that if the wind was blowing directly onto Bayesian’s beam and the yacht was in the
‘motoring’ condition, a gusting wind speed in excess of 63.4kts would likely result in the vessel capsizing"
...but it didn't capsize - it sank (due to water coming down the main stairs, reading between the lines of the report).
The angle of vanishing stability, in the configuration in which it sank, was estimated as 70 degrees - and the videos I saw seemed to show it blown further over than that.
Anyway, the report makes an interesting read (as do all the MAIB incident reports - they are addictive reading if you're interested in boats).
