So, we had a race yesterday that turned into a visit from Demon Murphy. On our way out to the start, my mainsail blew out a horizontal seam between the 1st and 2nd reef points. We considered bailing on the race, but it was a gorgeous day, so we reefed to the second reef point and entered anyway. Then on about our 5th tack headed to the windward mark,a section of the UV sun cover on the jib began to separate from the leach, and became a 4' flag in the wind for the rest of the race. We eventually were DNF'd on the last leg of the race for falling more than 30 minutes behind the rest of our class. It was still a great day on the water, and we got a lot of tacking practice as we fell further and further behind the fleet LOL. My question is, as these were used sails when I got them, I don't feel like investing a lot of money in repairs. How hard is it to restitch a mainsail? Can it be done by hand or will it require a sewing machine? Also, I have the same question regarding the UV sun cover on my jib. The fabric on both seems to be good, it is just the stitching that let go. Any suggestions or tips and tricks would be greatly appreciated. On our way out before Murphy's visit. Headed towards the first mark with reefed main.
