I just removed a Tides Marine track from my mast. I loved the system for cruising and general ease of use, but I removed it to save some weight aloft and I'm switching to a standard bolt rope.
Also have a North Dacron Main with the Tides Marine slides installed. It's in reasonable condition.
Sail easy to ship, not sure about the track. I can deliver to around the CT, NY, NJ area.
Offers around $1000 for the sail, $300 for the track.
