J/70 Sails - North Sails is the leader in one design sailmaking. On this page, you will find information about our complete line of J/70 sail models, J/70 tuning advice and J/70 news and results from the race course.

North Sails new J70 One Design Class Racing sails represent the leading edge of sail performance and are a result of North Sails unmatched design and manufacturing technology. For this new class, we have utilized our advanced North Design Suite of software to accurately model the aerodynamic flow, sail loads and rig geometry of the J70. This process has allowed to us create refined designs straight out of the box that are perfectly matched to the Southern Spars Carbon mast. The new J70 sails are also made from the revolutionary new North  Radian™ sailcloth. Radian™ sailcloth uses a unique (patent pending) process to create the world’s first warp-oriented woven polyester to harness the power and low-stretch of radial construction.

The all new J/70 represents one of the most exciting developments in sailing to come along in years. An affordable sport boat made by one of the best names in the boat building industry the J/70 is sure to be a class for the ages.

At North Sails we are excited to help J/Boats to get the class going by offering high quality performance  sails as part of the initial package for the boat. We have worked very closely with Southern Spars and J/Boats to develop a set of sails that will deliver top performance, ease of use and longevity. Using the North Design Suite (NDS) we have modeled and flown the sails on a loaded sailplan to simulate actual sailing conditions. By running iteration after iteration we have been able to fine tune the design of these sails. 

The main and jib are made from a new, cutting edge material called Radian™. This is a warp oriented, patented, polyester material with its strength in the long direction making it perfect for radial sails. Radial sails align the load in the sail more accurately with the cloth orientation and make a lower stretch and longer lasting sail. Until the creation of this sailcloth it was very difficult, if not impossible, to use this type of construction in a polyester sail.  The new J/70 will be the first large class to take advantage of this technology.

The drawings are screen shots of some of the modeling that has been done to develop the sails for this exciting new boat. The whole network of North lofts around the country and eventually the world looks forward to working with the J/Boat network to bring this exciting new boat to the forefront of sailing.
