NOTE: Values presented in this sail performance guide are approximations intended for relative comparison. They are based on experience and observation and do not represent specific test data. Variables such as sailcloth weight, film weight, coatings and other factors will have an affect on shapeholding, flexibility and UV resistance.
* Shapeholding: A measure of a sails modulus, or resistance to stretch. Higher modulus = better shapeholding and upwind speed.
** Flexibility: The degree to which flex (bending) affects the structure of a sail. A more flexible sail is able to withstand creasing & flogging better than a stiffer one.
*** UV Resistance: The resistance of a sail to the degrading affects of UV radiation (sunlight).

|
| 1 = Fill-oriented woven poly |
3 = Polyester laminate |
5 = Paneled Aramid/Technora
|
7 = UHMWPE* filament tape
|
9 = Ultra-carbon |
| 2 = Warp-oriented woven poly |
4 = Woven UHMWPE* laminate
|
6 = Aramid |
8 = Carbon
|
|
| Lower digit = LOWER MODULUS (more flexible/durable) |
Higher Digit = HIGHER MODULUS (better shapeholding / upwind speed)
|
