While the video was uploaded in 2009, the Hobie 20 Continentals were at Davis Island Yacht Club (I've been there many times and recognize the venue) in
2001.
At that event, boat #789 was registered to Vernon Kuftic and crew Pete Haley. I don't have any contact information for Vernon, but Pete Haley is still around and may be able to help. I'll send you his info via PM.
BTW, all major event information is stored in the HCANA Event Archive:
