Add Sail Slugs
Most sails are manufactured with bolt ropes. The rope fits into the groove on the mast, and usually requires a second person to feed the sail while the other pulls the halyard. When you lower the mainsail, it will fall back out of the groove. You want to install sail slugs onto the bolt rope. Buy the nylon with stainless bail type because they are more durable. You will also need to buy plastic shackles to attach the sail slugs. You should also buy a sail track stop, to insert into the mast groove after you raise the mainsail. The track stop will keep the mainsail in the mast when you lower it. I suggest that you visit a marina, and look at the boats there that have mainsails flaked onto the boom. http://www.westmarine.com/webapp/wcs/stores/servlet/SiteSearch?keyword=sail%20slugs&advanced=YES&searchDeptId=2http://www.westmarine.com/webapp/wcs/stores/servlet/ProductDisplay?keyword=108332&resultCt=1&storeId=10001&catalogId=10001&productId=1757&y=4&x=14
