TheJ/80 is an Americantrailerablesailboat that was designed byRod Johnstone as aone designracer and first built in 1992.[1][2][3][4][5]
The design is a recognizedInternational Sailing Federationworld class with a crew of threesailors.[6]
The design has been built byTillotson Pearson since 1992, forJ/Boats in the United States, with over 1,700 built and still in production as of 2022[update]. At one time it was produced byWaterline Systems, also located in the US.[1][2][7][8][9][10][5]
The J/80 is a racingkeelboat, with the hull built predominantly offiberglass. It has afractionalsloop rig with a retractablebowsprit controlled from the cockpit by a deployment line. The hull has araked stem, a plumbtransom, a transom-hungrudder controlled by atiller and a fixed swept finkeel. 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 transported on land on a towed double-axleboat trailer.[1][2][5]
For sailing downwind the design may be equipped with anasymmetrical spinnaker of 700 sq ft (65 m2). It willplane under spinnaker.[1][2][5]
The design has ahull speed of 6.29 kn (11.65 km/h).[2]
The boat is supported by an active class club that organizes racing events, theInternational 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-boatmatch racing.[12][13]
In a 1994 expert review inSailing 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]
