I switched to the 3:1 and I think that is helping. |

When I started this thread I was still rigged that way. I've gone back to 2:1 because I got tired of all the line in the cockpit at 3:1. It might slow the damage down but it won't stop it. |

Agreed. I think it is still fraying perhaps at a slightly slower rate. |

I am gonna try this by using the front fairlead in the back. I think that will work??? |

I think adding the fairlead might help but it would also add a lot more torque on the two little screws that are used to hold the cleat to the aka. I am afraid you could rip them out of the aluminum aka. They make a swivel block that can be mounted to the deck of the boat in front of the cleat which would turn the line to avoid the wear but I don't know if the deck would be strong enough so I'm still waiting for Hobie to come up with a solution. Here is a link to the type of block I'm talking about http://www.westmarine.com/webapp/wcs/stores/servlet/ProductDisplay?productId=92643&catalogId=10001&langId=-1&storeId=11151&storeNum=10102&subdeptNum=10172&classNum=10179 This one seems a bit much for the job but I ran out of time looking for a smaller one. |

Jerry, not doing it just yet, but I'm thinking about swapping the existing front cleats to swivel cleats. Then I could operate them from the tramps, with the tiller extension I'm thinking about. |

Max, Have you found a swivel cleat that would work in the rear? |

I searched the Harken site for the same cleats used by Hobie - couldn't find them! Also looked for a swivel cleat, something like this:  It's a Harken Cam Base #240 However, the base would need an adaptor to fit the xbar, and I would have preferred a fixed-position fairlead, with swivel cleat - for the front, anyway. |

Max, I wonder if Hobie is looking into this because the way the turn block is positioned in relation to the rear jam cleaat is the design issue that's causing the problem. Any cpmments Matt? |

Matt, Is Hobie looking into a way to correct this problem? |

Had not been following this thread closely. Engineers think that it wears mostly at the point of the cleating action. The quality of the line may not endure chafe as well as it could. I'll pass along the comments.

Matt, The turn block that leads the sheet into the cam cleat causes the line to turn at too sharp of an angle in the rear position, The angle on the front is not as sharp and so the front cleat doesn't chafe the line. If you take a new length of line and run it back and forth through the block and cleat holding tension on the line you will see the wear almost immediately. I don't think any line will stand up to it for any length of time. |

I don't see that the block is causing chafe on our boats here (just looked), but the cleat has a small metal reinforcement the ling drags over. Moving the block forward would reduce that angle / drag a bit, but not completely. |
