Class History

Thanks to a perfect mix of double-digit speed, quick planing, exceptional upwind stability, and tracking, the J/70 is your ticket to fun! J-Boats designed this lively, but easily-sailed sportboat to fulfill the needs of a diverse range of sailors—from performance one-design and club racers, to sailing families. A vertical lifting keel makes trailering and ramp-launching a snap. The large cockpit comfortably holds three adults or four mixed crew.

Since its launch in 2012, the popularity of this 22-foot superstar has soared, with growing fleets and regatta action worldwide. Superbly built by CCF Composites, Bristol, R. I., the J/70 was named 2013 Boat of the Year by Sailing World Magazine.

Underdeck Furler

493The 493 Underdeck furler lowers tack height, maximizing sail area. A ball bearing swivel on the headstay, allows you to raise/lower the jib or adjust luff tension. The jib halyard exits the mast and attaches to a 40 mm 2621 Carbo fiddle; the control line leads through a 40 mm 2148 T2™ Loop block and adjusts using a 396 29 mm Carbo Pivoting Lead block with Carbo-Cam.

Mainsheet System

The 5:1 mainsheet system features 2148 and 2151 Carbo T2 blocks that hang from a Dyneema® strop attached to the boom. A 2621 57 mm Carbo fiddle rides on the traveler car. A 57 mm 2135 Carbo ratchet atop a 144 swivel base finishes the system. The switchable ratchet allows the skipper to turn the ratchet off in light air, or on when grip is needed.

Spinnaker Halyard

2156A 40 mm 2156 Carbo® Pivoting Lead block attaches to the back of the mast. The spinnaker halyard exits the mast at centerline, runs through the 2156, and cleats at a 150 aluminum cam. The 2156 has a weight savings of almost 20% over the stainless version it replaces without sacrificing load capacity.
