The design is a recognized International Sailing Federation world class with a crew of three sailors.[6]

Production

The design has been built by Tillotson Pearson since 1992, for J/Boats in the United States, with over 1,600 built and it remains in production. At one time it was produced by Waterline Systems, also located in the US.[1][2][7][8][9][10][5]

Design
J/80 flying its asymmetrical spinnaker

The J/80 is a racing keelboat, with the hull built predominantly of fiberglass. It has a fractional sloop rig with a retractable bowsprit controlled from the cockpit by a deployment line. The hull has a raked stem, a plumb transom, a transom-hung rudder controlled by a tiller and a fixed swept fin keel. It displaces 2,900 lb (1,315 kg) and carries 1,400 lb (635 kg) of ballast. The cockpit is 12 ft (3.7 m) long and the hull has a sealed buoyancy compartment on the bow.[1][2][5][11]

The boat has a draft of 4.90 ft (1.49 m) with the standard keel. It can be ground transported on a double axle boat trailer towed by an SUV or van.[1][2][5]

For sailing downwind the design may be equipped with an asymmetrical spinnaker of 700 sq ft (65 m2). It will plane under spinnaker.[1][2][5]

The design has a hull speed of 6.29 kn (11.65 km/h).[2]

Operational history

The boat is supported by an active class club that organizes racing events, the International J/80 Class Association. There are 30 fleets racing in 12 countries, including in North America, Europe and China. It has also been used for two-boat match racing.[12][13]

In a 1994 expert review in Sailing World Magazine Doug Logan concluded, "In the test's light airs, the J/80 could often sail at or close to windspeed, and in several instances recorded the best leg times. While hard to define as a "conservative" boat, this Rod Johnstone creation doesn't go to the max in sailplan and (lack of) stability, and employs the proven construction materials used in thousands of earlier J/Boats. This might cost a bit of speed in light air with chop, but should broaden the boat's user-friendliness in stronger winds."[11]
