Oof. I cannot. My interest in sewing is at the garment to backpacking equipment scale. Everything I know about sewing sail fabrics comes from the crossover to the ultralight backpacking world. I know I was pretty down on the Sailrite, but if you're doing diy sail sewing, it's probably a pretty good compromise for the job. Background for non-sewers: all fabric stretches, but for most things on a human scale, you can ignore it when you're sewing. When you get into sail-sized products, you'll end up with puckering if your seams can't stretch with the fabric. A zigzag seam will stretch with the fabric. A straight stitched seam will not. Further background: AIUI industrial machines are a lot more job and/or fabric-specific than domestic machines. And you also get into needles and bobbins that you can't pick up at Joann. Your sibling commenter is likely more knowledgeable than I am. I was helping a friend doing some cushions for her boat. The Sailrite was struggling with the Sunbrella-type canvas. For sailcloth (on that size boat?) it probably would've been fine. Good luck!
