I need the dimension of the vinyl coated life line for a 1978 Cal 2 25.....anyone knows where to find this info?
Just check out some other boats of approximately the same size length. Off the top of my head, I would say something between 1/8 and 3/16" . (1X19 ss wire).
If you can buy a tool (relatively inexpensive) and the kind of terminals you want, depending on how fancy you want to get, you won't have to hire someone else to do it. Or, a less elegant way is to use nicropress fittings. (though you won't be able to remove the lifelines from your stanchions once you're done.
