The wind value that indicates the MAIB ratio as a condition that leads to the Bayesian overturning could arise from the determination of the KNOCK OVER value estimated at 63.4 knt.
The 70 knt cited could be the result of an interpretation, of a sort of conclusion reached by the English experts, but not be the result of a real measurement.
If this value of 70 knt had actually been measured, there would have been evidence of the measurement but we would believe, above all, that a wind of such intensity would have had heavy effects also on the very close Dutch schooner that instead did not report any evident damage, as well as on the entire port area.
