My Dad has told me this same story many times...he sailed that day (Geoff Dobbs) and also recalls a young crew (son of Reg?) getting hypothermia from the very cold water being stirred up from 10 feet below.
That sounds like what happened to Rick White (not Reg). Rick was sailing with his son Todd, who was about 12 years old, around that time. But Rick says he did not go to CORK that year and that Todd's hypothermia happened at the Tornado Worlds in Toronto. So maybe it is a different incident.
