D4® – Multi Panel ™
The D4® Multi Panel™ product line is DIMENSION-POLYANT’s most recent addition within the D4® family of membranes for yacht sails. D4® Multi Panel™ membranes are most suitable for boats up to 40 feet.
D4® Multi Panel™ is designed to manufacture membranes in a speedy, highly automated manner employing advanced lamination and custom yarn trajectories. Multi Panel™ employs laid high modulus fibers which are load-path oriented and laminated between two layers of film. Taffeta and Internal Taffeta versions are available as well.
The D4® Multi Panel™ line offers a more precise draft profiling for the membrane owing to the multiple seams of the Multi Panel™ configuration. This feature is most useful in sails used on boats under 40 feet, where more shaping is required. DP’s patented roll good lamination, as applied in the production of the custom layout of a Multi Panel™, provides a quality superior to most membranes found in the market place at such a price level. The resulting performance and durability is reflected by winning results from world championship competitors to club racing sailors looking for the ultimate in weight to stretch ratio.
With this new product offered within the D4® family, sailors around the world can now choose from the most comprehensive membrane range to find the correct sail solution for every yacht. Although D4®Multi Panel™ is visually different from D4® Premium and D4® Fastline in panel size and yarn distribution, the performance elements of the sail membrane is maintained.
