If you are going to replace the line, attach a messenger line to the existing line and pull out and then go to a marine store. If it is too short, add several feet. I am not sure where you are but in the United States, Selden mast which would know is located in North Charleston, South Carolina and their phone number is (843) 760-6278. If pulling out, it is easy to put one back in with a messenger line in place
