X-Drive - Racing Mainsail
X-Drive® is the ideal sail construction process for racing sailors who appreciate a well-shaped sail, but who also need to keep control of cost.
Holds Its Shape
X-Drive is a two-part construction method. As the diagram shows, the sail is made from a light weight material cut into cross cut panels that when put together with broad seaming achieve the 3-D shape created by the sail designer. Next the sail is reinforced with a grid of narrow high-strength, low-stretch fibers that are bonded to the sail up to 11 at a time.
UK Sailmakers’ X-Drive construction system uses a grid of continuous high-strength low-stretch fibers to support the sail’s flying shape. Since the fibers run across the shaping seams, the seams are locked in place and cannot distort. With hundreds of closely-spaced fibers bonded to the sail’s surface, the sail has incredible strength and stretch resistance, which results in a smooth sail without distortion.
The cost of the sail is also controlled because the sail surface can be made out of a less expensive, lightweight laminated material, whose only job is to give the sail its 3-D shape. All the sail‘s strength comes from the dense grid of continuous high-strength fibers that are bonded to the sail’s surface.
