2021 Island Packet 525

Our flagship model, the IP 525, provides the best of all worlds. The large aft deck is perfect for sunbathing, impromptu dining, and large enough to accommodate a 10’ dinghy, easily hoisted with a clever boom extension system. Below, you’ll be immediately impressed by the panoramic view of the open, main salon, spacious forward and aft cabins with private heads, and solid teak and oak soles throughout. The gourmet galley, multi-use third stateroom, and state of the art navigation center rival those on much larger yachts. Climb aboard the IP 525 to find enormous living space, large circumnavigation storage, and enough sail to speed you comfortably to your destination.
