Easiest Solution only $16.00
The easiest way to solve this problem of the sheet jumping out of the Ronstan C-Cleat is by adding a RF5014 Rope guide in front and a RF5015 Fast Track Fairlead in the rear. These are available from West Marine (2003 catalog page 895 Models 214819 and 544999 at $3.99 each)Install by removing the two screws (don't worry about nuts, they go into a backing plate), slip in the parts top and bottom and re-install the screws. You can adjust the sheet from any angle; even from the other side of the cockpit. If you need to pull in tighter, don’t use the winch, just turn into the wind and pull. Instead of a knot at the end of the sheet, tie a loop. This way you can release the line on a tack, and use your index finger to grab the opposite sheet, held by the fairlead, and pull. I have attached a photo.This has been a common problem raised every few months.
