FWIW, there are a bunch of different sailing "records" in this part of the globe - usually for fasted time between selected places and usually managed by the CYCA. There are (usually) no prizes awarded and (usually) the press don't even notice. Some of these "records" include:
Melbourne-Hobart (East Coast)
Melbourne-Hobart (West Coast)
It just so happens that this one was for a journey between Sydney and Hobart and I can understand that might give some overseas the impression it was related to the race - which it isn't - but, as usual, the news-media world-wide want publicity, not accuracy. Must have been a slow news day.
EDIT: Certainly no-one here gives a ..(insert appropriate expression here).. whether it's a monohull or a multi-hull that holds the "record".
