Past experience has shown that these conditions can overwhelm smaller boats and crew. They also lead to damage to sail/rigging etc.
Criteria for forecasts will be taken from:
B) WindFinder, and
A combination of the above has been found to be consistently more reliable than NOAA alone. Permitting larger boats, that may be able to handle such conditions, to continue racing while smaller boats face unacceptable risks would not be consistent with the Corinthian spirit.
