Hi 170 sailors,My wife and I were sailing the 170 on Sunday and had full tension (decent & puffy breeze/jib sail close-hauled) on the jib, when the active sheet (port tack) slipped out of the port cleat's grip! Man, that sheet popped out of there with some serious force- and the boat immediately leveled down off of heel. I'm wondering if anyone has had issues with their Harken cleat claws slipping? Could the claws be wearing down? Could the jib tails be the culprit (they're original 1999 vintage, but still in apparently good shape)? Any experiences/thoughts in this area would be really helpful.Best,Mike G. -s/v Lil SportAlachua, FL
