I have a Selden in-mast furler for my main sail and the halyard car is getting stuck. I have a 2007 Hunter 41DS. This is the second season this has happened. Last spring a sail maker friend of mine beat on it with a hammer until the car freed and I was able to put the sail on. I don't like the idea of pounding on my mast every spring. The car is getting stuck on something inside the mast that I can't see and I'm not sure I can fix. Like most places, there are very few qualified riggers in my area. Has anyone else encountered this problem and how did you solve it. The halyard moves freely, so I know that not the problem.
