I am replacing several of my running rigging lines. Owner's manual line sizes appear smaller than what is on my 2000 Hunter 290. Also, they appear to be cotton, vs. polyester? Example, the main halyard in manual is 3/8", looks a little dinky. I bought boat used, but would be surprised if they previous owner re-fitted the entire boat with color coded line as in owners manual. Does anybody have thoughts about early 2000 Hunter's and factory line selection?
