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

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.

The Island PACKET 380 is a 12.1-meter cutter-rigged sailboat with a long keel, designed by Robert K. Johnson and built by Island Packet Yachts from 1998 to 2004. Its full-foil keel, a design by Johnson, uses NACA airfoil sections to provide tracking stability and gentle motion with a draft of less than five feet, while generating hydrodynamic lift. The hull is a one-piece, hand-laminated solid fiberglass molding with no keel bolts, featuring triaxial knitted laminate and a proprietary Polyclad gel coat system. The Island PACKET 380 has a displacement of 9525 kg and a beam of 4.0 meters.10:58
