IMO, it all depends on the vessel and the experience of the captain & crew.
If I were in a 35' Beneteau I'd probably stay put. But I'd have no worries in 30 kts in a Voyage 500. Put the 2nd reef in and only unfurl 2/3 of the genoa, and off I'd go.
Hell, in the 2012 Anegada Lobster Regatta we saw winds gusting into the 40's, with some boats reporting even higher. Other than arriving wet due to the squalls, we were otherwise unfazed. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Cheers.gif" alt="" />
