I am having my roller furling gib repaired. Luckily one of my small sails fits in the furling groove and I raised it. Although it furls, not perfectly, it has no sunbrella nor uv nylon sewn into the sail. Therefore all of the exposed surfaces of the sail have no protection. I expect only 2-3 weeks till my other sail is ready to reinstall. Is it okay to leave the unprotected sail up on my boat for this length of time? I figure ocean going sailboats leave their sails up for weeks at a time. Before this, the sail was hardly used and has just been stored in the cabin berth in its bag. It is made from heavy white dacron. RonE
Often, smaller furling sails are made without uv protection, because they're only used in the Spring and Fall, when uv rays aren't as strong as in mid-summer, when the temps are regularly in the mid-90s. Leaving them hanked on for 2-3 weeks in the Spring or Fall would not be a big deal. I've done it with my 110%. But, you're taking a chance when you do it in the mid-summer heat. It won't ruin the sail in three weeks, but it might permanently discolor the outer layer of sailcloth, giving it a yellowish hue.
If you spend weekends on the boat, and will sail it both Saturday and Sunday, then I'd suggest you leave it on until you're ready to go home, and then remove the sail, so it isn't in the sun all week. If you are likely to sail it only one day each weekend, then I'd remove the sail after each use, and fold and bag it. I crew on a number of different racing boats, and we remove the jibs, fold and bag them after every time we sail the boats, and it's not that much effort.
A couple weeks should be no problem... If you want some protection, you could apply some alcohol-based sun-block along the edges--the non-greasy kind that comes in spray bottles. Alcohol is recommended for removing some things from Dacron, so it should be no problem.
