A sailmaker makes and repairs
sail
A sail is a tensile structure—which is made from fabric or other membrane materials—that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may ...

sailboats
A sailboat or sailing boat is a boat propelled partly or entirely by sails and is smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture.

kites
A kite is a tethered heavier than air flight, heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create Lift (force), lift and Drag (physics), drag forces. A kite consists of wings, tethers and anchors. ...

; the sail loft has other sailmakers. Large ocean-going sailing ships often had sailmakers in the crew. The sailmaker maintained and repaired sails. This required knowledge of the sailmaker's craft and the tools of the sailmakers loft on shore.
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. Sometimes a sailmaker will accompany the client out on the water and adjust the sails. The modern sailmaker uses computer-aided

tools. Computer graphics allow the sailmaker to produce a "lines drawing" of the sail. Once the design is complete, the sailmaker can now use a low-power laser to cut the material to the exact shape.

Sailmakers have recently started using
Computational fluid dynamics
Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid flows. Computers are used to perform the calculations required to simulate th ...
(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.

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.
