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 tapes that are bonded to the sail up to 11 at a time in an 8 inch (20 cm) wide path.
UK Sailmakers’ X-Drive construction system uses continuous high-strength low-stretch yarn reinforced tapes to support the sail’s flying shape. Since the yarns run across the shaping seams, the seams are locked in place and cannot distort. With hundreds of closely-spaced yarns 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 yarns that are bonded to the sail’s surface.
