The new mainsail is being fitted with new slides made from 316 stainless that fit into a UHMW track (ultra-high molecular weight which is very strong and abrasion resistant) that slides into the original mast luff groove. This system by Tides Marine lowers the friction and makes it easier to raise and lower the mainsail. I installed the one-piece track by first cutting a new slot in the aluminum mast groove using a dremel tool with cutting discs. Next, the new track, which came in a big roll, was fed into the slot and slid all the way to the top of the mast. I had to remove the boom so there would be no angle when feeding the track up. This was an easy project that took about 3 hours.
