Draft Stripes

Contrasting draft stripes help sail trimmers see the aerodynamic shape of the sail.

To help visualize the aerodynamic shape of the sail, UK Sailmakers applies contrasting, horizontal stripes to the sail at several different heights. Draft stripes can also be used in shape analysis software, like UK Sailmakers’ AccuMeasure that you can download for free.
