• 1W70 and Dacron 52 in load bearing fill. Warps include 1W70, Dacron, Acordis 57T, Kosa.

• 4.93 is for small boat mains, jibs, and genoas.

• 5.53, with tough 250 yarn in both directions is for low aspect mainsails and genoas.

• The New 6.53 is a very fine weave 250 x 370.

• 7.03 (formerly the 6.53 construction: name changed to reflect actual weight) is applicable for mainsails and genoas with 2.5 / 1 or less aspect ratio.

• 8.03 is applicable for mainsails and genoas with 2.5 / 1 or less aspect ratio.

• 9.03 is a new style, suitable for mains and genoas with around 2.5 / 1 aspect.

• New 10.53: fine weave for 2.5 / 1 or less.

• 11.93 is suitable for mains and genoas with 2.5 / 1or less aspect ratio.

Low Aspect Weave Concept

• Lowest bias stretch to resist higher bias loadings of big mid-girths in lower aspect sails.

• Highest fill count, tightest weave for best possible bias stability.

• More even crimp, where yarns grab each other means lower bias stretch.

• Bias stability is better in even denier weaves than when there is large disparity between warp and fill.

• Larger warp yarn and smaller fill yarn than high aspect fabrics.

High Aspect Weave Concept

• Large fill yarn to counter high leech loadings in tall and skinny sail.

• High "sley", that is high count of warp yarns.

• Warp yarns touch each other, creating tunnels that encapsulate the fill yarn.

• High fill count, for best possible bias stability in a fabric with large disparity in warp and fill yarn size.

• High tenacity yarns in both directions where possible.
