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 ma ...

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. Types Although sailboat terminology ...

kites A kite is a tethered heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create lift and drag forces. A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face ...

, wind art, architectural sails, or other structures using sails. A sailmaker typically works on shore in a sail loft; 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.
