Making Your Own Sails
Making your own sails from a sailrite kit is a practical endeavor if your boat is less than 25''. Larger boats require heavier and larger sails. The heavier material and larger bulk makes it difficult to sew on anything but a heavy duty machine.
A first timer trying to cut his/her own sails and sew them is pushing the odds. The result will likely be less than optimum and disappointing.
I made a genoa for a 23 footer I had at one time. It was a sailrite kit and was good quality and the instructions were very good. However, the machine I had to use at the time was really struggling to sew though multiple layers of material. Trying to feed the rolled up sail through the machine and sew a straight seam was a real challenge.
Just my experience.
