The clew attaching point on a prindle sail will be a single grommet. Also, a prindle sail attachmet is out past the rear beam. On a boomless rig, it needs to be a little forward of the rear beam or the sheet will be pulling the sail towards the mast as it is sheeted in instead of away from the mast as needed. Also the prindle is loose footed and has no bolt rope in the foot for some type of boomlet.

The problem I have found with reefing the ring and hook halyard is if it is reefed, you can't hook it and have to cleat the halyard to tension the sail. The halyard streaches bad. I tried a cable about 3' or so to make up the distance between the headplate and the hook, but it was impssible to engage the hook without laying the boat over and doing it by hand. I tried it for two seasons and finally realized a sail made for the specific boat was way worth it. You may be able to find a used sail for the Supercat 19 here or on other cat sailing sites or try SPS. I have mixed and matched a few boat parts before, but is it always a royal PITA to get right.
