General Information For The IP320
Island Packet 320
The Island Packet 320 combines the extensive building, sailing, and design experience that have made Island Packet Yachts America's Cruising Yacht Leader. Using owner feedback from millions of miles of cruising experience, noted naval architect Bob Johnson designed the IP320 to maximize offshore capability and liveaboard comfort. Cruising World magazine confirmed the success of this design by awarding the IP320 its Best Midsize Cruiser honors in the 1998 Boat of the Year contest.
