Overview
The Island Packet 380 is a Bob Johnson design built by Island Packet Yachts in Largo, Florida, from 1998 to 2004, with 169 hulls completed. It embodies the yard’s long-standing philosophy, summed up by the company itself as safety, seaworthiness, and simplicity, applied to a cutter-rigged, full-keel cruiser aimed squarely at couples doing coastal exploration, tradewind passages, and extended liveaboard cruising rather than performance sailing.
Design and Construction
At 21,000 lb displacement on a 13 ft 2 in beam, the 380 carries real interior volume, reviewers have described it as feeling like a 42-footer inside despite a 39.6 ft LOA. The standard keel draws just 4 ft 7 in with an encapsulated lead ballast keel, while a centerboard version can be lowered to draw 7 ft 7 in for extra windward performance, an unusual combination of genuine shoal-draft cruising and a deep-water option from the same hull. A cutaway forefoot and protected rudder are typical of Island Packet’s whole range and are built specifically to tolerate groundings that would damage a fin-keel boat. Yachting Monthly’s reviewer describes the hull as solid laminate and a single moulding, with the deck cored with Polycore and the two bolted and bonded together. A structural pan forms the sole, and the bulkheads, webbing and many bunks are bonded to the hull, which he calls more labour intensive than tray-style construction but much stronger. The cap shrouds and lowers each terminate at one of three chainplates that are welded and braced together with a framework locked into the hull-to-deck joint before being glassed to the hull. The same review quotes a surveyor who found, on two Island Packet 380s after groundings, water in the keel void that had softened the lean sand and cement mix around the lead ingots.
Under Sail
A capsize screening figure of 1.91, just under the 2.0 offshore threshold, and a comfort ratio near 31 describe a boat built for a settled, forgiving motion rather than speed; one reviewer’s “tortoise not hare” description is a fair summary. John Neal’s Mahina list rates the Island Packet range 4 out of 5, calling the boats “roomy and comfortable, good tankage and storage but some unusual features.” On Yachting Monthly’s test the 380 made 5.5 to 6 knots upwind at apparent wind angles of 50 to 55 degrees in Force 4 and above, and reached at 6.5 to 7 knots in a blustery Force 6. In 6 to 8 knots of breeze she managed 3.5 to 4 knots. The reviewer said the large rudder gripped even when a 30-knot squall hit and never threatened to round up. He felt a slab-reefing main in place of the in-mast furling and newer sails would have given better performance, and he noted the self-tacking staysail gives better tacking angles in stronger wind.
Buyers Notes
Neal’s note specifically says to favor Island Packets built after 1998, when an earlier chainplate issue was addressed; since this model’s production began in 1998 itself, ask for the exact build date and any chainplate service history on any 380 from that first model year rather than assuming the fix was already in place. Confirm whether a given listing has the standard shoal keel or the centerboard-equipped deep-draft option, since that changes both draft and expected windward performance meaningfully. Below, Yachting Monthly describes a large U-shaped galley with a top-loading fridge and freezer, an island bed in the forepeak master cabin, and an athwartships aft double. The small aft-facing chart table has no backrest and is impractical at sea. On deck the chain locker is split in two to take both sets of chain, with twin bow rollers, and a sloping shelf beneath the hawse pipe helps the chain self-stow.
