Sewing machines which produce zigzag stitches and have a "Long Arm" are relatively rare. These machines are desirable for sailmakers building large yacht sails. Arm length is the horizontal space between the needle and the vertical upright of the sewing machine casting. The longer the arm, the more space there is for the rolled sail or canvas section which is to the right of the needle while sewing. Sailrite's long arm sewing machines are 20.5" compared to roughly 7" to 10" standard arm machines. Machines of this type can sew both zigzag and straight stitches. Some even produce 4-point zigzag stitches (sometimes called 3 step zigzag stitch).
