About a year ago I posted that I was serving my dock lines to reduce chafe. Where they contact the pilings and the dock cleats and the mooring bits on deck. I am please to be able to say the the hard serving completely protected the 3 strand laid nylon. There are some places where the service needs replacing but the lines are undamaged. Also I hang a pair of fanders over the stern and the rope that holds those is served where it chafes the turn of the transom. In year past the lines needed to be changed every year but this time they are in perfectly good shape for another season.
