Island Packet 380
Description
The Island Packet 380 is a renowned American bluewater cruiser designed by Bob Johnson and produced by Island Packet Yachts from 1998 to 2004, with 169 units built. At 39.58 feet LOA, it exemplifies the brand's "safety, seaworthiness, and simplicity" philosophy, featuring a cutter rig, long keel for stability, and solid fiberglass construction ideal for couples or small families pursuing coastal exploration, tradewind passages, or extended liveaboard cruising. Its wide beam (13.16 feet) and high coachroof deliver exceptional interior volume—feeling like a 42-footer—while the encapsulated keel and protected rudder enhance grounding resilience. Known as a "tortoise not hare" for its deliberate pace and comfort, it's praised for offshore capability but critiqued for modest speed and windage.
