I have a 1980 Cal 25 and would like some advise on spring lines. The boat does not have a quarter or mid ships cleat, and a rail that prevents running a line to one if I installed a new cleat. Currently I run a line from the bow down along the side to a dock cleat off the stern, and a line from the stern to a dock cleat by the bow. I don't like the lines rubbing against the side of the boat. Any suggestions?
