Just take it apart, replace the line and maybe the pulleys, re assemble, go sailing! I have mine apart as we speak and found the pulleys all in good shape. reeved new line with enough to take it back to the cockpit. The biggest challenge was to remove the screws for the end caps. I had to use an impact driver, to get them to move. One unfortunately twisted off. If you freeze the screw head with an fluid from a canned compressed air( used for cleaning camera), that can help.
