We bought a '86 Irwin Citation 38 last year. The boat's owner didn't do much maintence, I imagine the winches were never serviced. We know that the barlow (2 speed) self tailing winches don't self tail properly. One doesn't do it at all and the other - the line constantly slips. We are planning on fully servicing the winches this spring - but I am wondering if the failure of the self-tailing feature might be that the rubberized grips at the top are old or not gripping or possibly that the jib sheet line isn't properly sized. Any ideas?
