[1] Today, one of a sailmaker's important jobs is to teach people how to set and trim their sails to get the most out of them.
Computer graphics allow the sailmaker to produce a "lines drawing" of the sail.
[4] Once the design is complete, the sailmaker can now use a low-power laser to cut the material to the exact shape.
[5] Sailmakers have recently started using Computational fluid dynamics (CFD), the study of the flow of fluids over or through physical objects, in order to create more efficient sail or foil shapes in the design process.
[6] After CFD analysis is run, complex data sets can be rendered graphically to enhance understanding of the design's likely results, before sails are ever cut.
