At UK Sailmakers Texas we’ve had an incredible amount of development in our partnership with UK Germany and Claus Lehmann, owner of J/70 #717. We’ve developed a new mainsail based on the differences between the US-based Southern Spars masts and the European Selden masts — our European design has more luff curve, allowing us to utilize the softer spar.
The UK Texas J/70 sails were developed by combining the available information on this class with our experience in light-displacement sailboats and other J/Boats classes, using UK’s sail design programs for a complete 3D view and multiple panel configurations.

At UK Sailmakers Texas we’ve had an incredible amount of development in our partnership with UK Germany and Claus Lehmann, owner of J/70 #717. We’ve developed a new mainsail based on the differences between the US based Southern Spars masts and the European Selden masts. Our European design has more luff curve allowing us to utilize the same tuning guide and jib for both setups. We’ve also begun utilizing Dimension Polyant’s new Pro Radial material which is specially designed to meet the high demands of high performance radial sails like the J/70 jib. Just below is a shape shot of our fourth generation J/70 jib design.
Sail Design
The UK Texas J/70 sails were developed by combining the available information on this new class, alongside of our experience with light displacement sailboats and other J/classes, using all UK Technology sail design programs (One of the most advanced sail design programs), allowing us a complete 3D view and multiple panel configuration.
UK Texas designed an all-purpose mainsail utilizing cross-cut Dacron with radial corners and a radial Jib made of square Dacron, which was made for all conditions. We have also designed a heavy air radial Mainsail. The kite was designed by UK Chicago, and is constructed with AIRX Nylon. It was designed to sail deep while keeping on plane yet does not lose performance in light breeze. Since the J/70 has a stiff Carbon fiber mast, we chose a cross-cut panel configuration with radial corners for the AP Mainsail in order to have enough variation of shape for different wind conditions and a Tri-radial Jib with 245SQ Dacron in order to hold the shape for all conditions. Sails are made in USA at our loft in Houston TX.
