Durable, Low-Stretch Cruising Sail

Tri-Axis Laminate sails are high-quality cruising sails that are both durable and low stretch, maintaining long-lasting shape and performance.

Sail Options

Every Tri-Axis sail is custom-designed by the Ullman Sails Design Team to ensure optimized sail trim.  In addition, the custom laminate characteristics make your boat easier to helm and your sails easier to trim.

  • Low stretch translates into less heel and less weather helm. By keeping the boat flatter and reducing the need to reef, cruising is safer and more enjoyable for you and your family.
  • The Custom Vectran thread lines in each section capture all the loads of the sail to keep the shape smooth and efficient through a wider range of conditions.
  • Tri-Axis sails are a similar weight to Dacron sails, but stronger.
  • Tri-Axis sails are designed to be roller-furled, making storage simple and easy.
  • Performance cruisers choose Tri-Axis sails because of the laminate's efficiency, power and pointing ability.
  • The performance life of Tri-Axis sails will significantly outlast Dacron.  However, if you expect to use your sail for the next 15 years, regardless of what shape it may have, then you may want to consider Dacron.
