Still have old sheets? Try them. I suspect the VPC is slightly small and it is very slippery in my experience. Bill Walker CnC 36 Pentwater, Mi.

You might want to remove them one at a time and lube them with tef-gel, or anti-seeze. If they get stuck they break. If they are over torqued they break. If they are not fully tightened or the springs are old or the line is too small of a diameter then line won't stay in. As long a the above three conditions are met then the problem you are having is with the friction on the drum. It sounds like those three conditions are met since you only experienced this problem in heavy winds. As mentioned extra wraps should help add friction. Additionally a machine shop can re-knurl the drum. You can also add a sleeve to the jib sheet. If you have the crew to do so, try having them not use the self-tailer to winch in on the tacks. See how much pressure the tailer needs to apply before the winch slips. The tailer should only have to apply moderate tension. If they are really pulling you need another wrap (or 2). If you have 4 or 5 wraps and the winch still slips then you need more friction. Sleeving the sheet is probably a little cheaper and will make the line better on the hand. You can also do it yourself. If you still find that it takes 4 or more wraps I would start looking for a machine shop. I have one in mind if you are interested. We had 4 wraps on the drum so I am thinking friction on the drum. I don’t know what re-knurling means and don’t know if any shop would know how to do this. Also, I have not found a good machine shop in my area. What shop did you have in mind? What would you sleeve the sheet with?
