History

Alan Johnstone designed the J 70 in 2012 as a fast, simple sportsboat that could be trailered, rigged quickly and sailed by mixed ability crews. It became one of the fastest growing keelboat classes ever built, with close to 1,900 boats on the water and fleets in 25 countries within a decade.

Sailing Characteristics

The fixed keel and asymmetric spinnaker keep the J 70 stable and easy to handle while still giving genuine sportsboat speed and planing runs downwind. It rewards tight boat handling without punishing a crew for a bit of extra weight.

Racing Context

The International J 70 Class Association runs an annual world championship plus continental championships, and the boat anchors sailing league formats across Europe and North America.
