You guys are going way to deep into this . If the problem is to solve the slight release or slippage of the rope in the pivmatic cleat, I solved that problem on my 6.0 by simply adding a Hog ring to the line at the tightest point on the rope possible. I actually made the rings from stainless welding wire that I already had. This made them of a lighter weight and smaller. They passed easily through the cleat fairlead and didn't get hung up. When pulling down the rudders, I simply pulled the rope and made sure the ring rested on the face of the cleat.
Results, No more slippage and the rope was easier and faster to pull out of the cleat. Hope that helps
