Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

LivelySea-kindly

Her heavy displacement on a moderate beam gives 31 — a sea-kindly motion in a seaway.

Comfort ratio 31
CoastalBluewater

1.91 — just under the 2.0 offshore line; her beam is modest for her weight.

Capsize screening 1.91
LightHeavy

286 — heavy for her waterline, built to carry stores and ride steadily.

Displacement / length 286
EasygoingPowered-up

15.9 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 15.9
TenderStiff

43% of her weight is ballast — stiff, standing up well to her sails.

Ballast 43%

A capable cruiser that sits just inside the offshore line — coastal work with real passages in her.

What the fleet has seen

The Island Packet 380, as the fleet has seen it

Derived from the videos the fleet has analysed of this model. ▶ marks open the moment aboard.

The Island PACKET 380 is a Robert K. Johnson-designed cutter-rigged sailboat built by Island Packet Yachts between 1998 and 2004, featuring a long keel, 12.1 m LOA, 4.0 m beam, 1.4 m draft, and 9525 kg displacement. Its full-foil keel, a signature of designer Bob Johnson, uses NACA airfoil sections to combine tracking stability with hydrodynamic lift and a shallow draft.7:10 This design provides the gentle motion of a traditional full keel while offering improved performance.7:22 The boat's construction includes a one-piece, hand-laminated solid fiberglass hull and keel molding, eliminating keel bolts, and uses a proprietary Polyclad gel coat system.8:09 Lady K Sailing notes that heavy-displacement, full-keel vessels like the Island PACKET 380 are proven ocean-crossing boats, prioritizing structural integrity and sail plan versatility.7:55 While Island Packet models retain value better than some production boats, they may have a smaller buyer pool.7:07
