... let me give you some of the most valuable sailing advice I can. Learn to tie a bowline knot. Second most valuable recommendation: Buy and study John Rousemaniere's Annapolis Book of Seamanship. Don't hesitate.Now... you need to invest in a new set of jib sheets. That would be two pieces, no larger than 3/8" diameter, rope length is approx. 1 1/2 time boat length. Good quality polyester double braid, such as New England Sta-set, Samson LS, Yale yacht braid, is more than adequate. Attach your sheets to the sail with a bowline. Absolutely no shackles, Please!!!!! Don't leave them attached all the time, remove them when you're away from the boat. They will last a lot longer because they are out of the weather and are getting rotated.Do not store your sheets in the bag with the sail, still attached. Bad for the sail. A continouse line with a cow hitch is okay for dinghy size boats, but not practical for boats over 25 feet.When tacking, try to let the wind carry the sail across the deck, rather than pulling it with the new sheet.
