From what I've read (no practical experience) Hunters in general are not blue water cruising type boats. They are more a a lightweight coastal cruiser at best and more of an inland sailing boat (Inland being lakes and sheltered waters)
However soon there will be the obligatory "I've circumnavigated the world via the southern ocean beating to windward in a constant gale with my hunter."
I'd start here:
