The biggest reason a regular, domestic sewing machine won't work well is the material with which you're working. Polyethylene terephthalate sailcloth, commonly known by the brand name Dacron, is light enough that a common machine can stitch through it without slipping, but not when multiple layers are being put through. Generally, sailcloth is made of at least four layers of cloth, sometimes ten. To handle this much material, it's best to use a commercial-grade machine. Another reason to use a industrial sewing machine is the type of stitch you'll be relying on, namely the zigzag triple-stitch. It's not a complex stitch. Yet with the strain the wind applies to the sailcloth, it's best to have the securest stitches possible. Moreover, the industrial sewing machines are of much better quality in a large manufacturing environment.
