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.

Here's our new updated inventory for 2016:




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 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.

J/70 M-2 Radian Race Mainsail
 
Original North winning mainsail featuring new split-weight construction 
<pclass="h1r">

1st 2014 Worlds! 
2nd 2015 Worlds!
1,2,3 2014 North Americans!


This is the tried and true original design that has been fast and winning regattas from when the J/70 class made it's debut in 2012. The M-2 is made of durable North Radian cloth and is a proven performer. The powerful designed shape flattens out nicely and reacts to aggressive use of the backstay when the breeze is up. This summer we introduced split-weight construction on the M-2 using a lighter, more forgiving North Radian cloth in the luff and slightly heavier North Radian in the leech for added durability and low stretch.

The North J/70 M-2 Radian Race Mainsail comes standard with:

  • Nordac Radian™
  • Radial panel layout
  • Luff curve and camber designed for carbon fiber mast
  • 1 Gaff batten

NEW J/70 XCS-1 Crosscut Mainsail 
New design for Summer 2016!


1st 2016 Worlds!!!

The XCS-1 main is an all-purpose sail for all conditions. The traditional crosscut panel layout allows the rig to be set quite loose in light air, to maximize headstay sag, power and pointing ability. It also easily accommodates the increase in rig tension and backstay that are needed in the J/70 to depower in big breeze. The crosscut construction allows the sail to better match your mast bend when the backstay is on hard. This balanced design has proven to be very forgiving with the ability to maintain maximum speed longer creating a wide “groove”.

The North J/70 XCS-1 Crosscut Mainsail comes standard with:

  • Luff curve and camber designed for carbon fiber mast
  • 1 Gaff batten
  • 2 full length batten  How to tension battens?
  • 2 leech battens
  • Loose foot
  • Vision and Spreader Windows
  • Radial teardrop patches
  • Spreader chafe patch
  • Trim stripes
  • Leech telltales
  • Class insignia
  • Adjustable leech and foot cords
  • Roll bag

J/70 SDM-1 Radian Race Mainsail
 
Excels in Light-Medium condition


1,3,4,5 at 2016 Key West Race Week!

The SDM-1 main was designed to perform on a mast with less prebend so it has less luff curve and sets up well on a straighter rig with less rig tension. This allows the forestay to sag more to create a powerful setup in the light to moderate conditions. This sail also has the ability to depower nicely in the big breeze. Since the shape on the SDM-1 main is placed higher it provides your team with more power when the traveler is up and the sail is twisted. This gives the sail plan an extremely forgiving setup in light lump. The SDM-1 Main, like the M-2, also features a split weight construction.The luff of the sail is made with a lighter, more forgiving North Radian sail cloth which allows the sail to set up well in a wide range of backstay settings..

The North J/70 SDM-1  Radian Race Mainsail comes standard with:

  • Nordac Radian™
  • Radial panel layout
  • Luff curve and camber designed for carbon fiber mast
  • 1 Gaff batten
  • 2 full length batten  How to tension battens?
  • 2 leech battens
  • Loose foot
  • Vision and Spreader Windows

"I can't say enough good things about the support we have received from the North One Design J/70 team and how it has helped our speed. Tim spent time with us before the Annapolis NOOD talking about light air tuning and jib trim. The regatta was light air and we were in the hunt to win overall till the end. The sails looked great and were fast. We finished 3rd overall and 1st Corinthian team!" - Peter McChesney

J/70 SDJ-1 All-Purpose Jib

New powerful design, optimized for light-lumpy conditions


After years of testing to find a jib that performs as well as the J-2, we have developed the slightly fuller SDJ-1 Jib to perform in light and lumpy conditions when it is difficult to use a lot of weather sheet. This sail sets up with a powerful shape with less weather sheet but can carry up the wind range very well. The SDJ-1 Jib can still be trimmed with substantial weather sheet if so desired with the lead slightly aft. This sail also features split weight construction.
