I have recently relocated the family ensign, Tango 2013, from lake Chautauqua to Eagle Creek in Indianapolis and we are getting ready to rig it for the first time (previously have always had the marina do it for us). While making sure I had all the lines etc. I came across this line that I have never seen before. Does anyone recognize this and/or know what it is for (picture attached)?
Looks like a line with several sliding blocks with zip ties extending from some...
