I'm replacing the main sail. The boom is a U.S. Spars Z160. There are three internal lines (outhaul, topping lift, reefing). However, the previous owner didn't use original colors, or lengths. It's not in the owner's manual, not on the Z-spars site that I could find, and not previously answered in this forum. I did call Z-spars, but the lengths quoted don't seem right, for example, why would the topping lift line be twice (9.5 M) as long as the other two (5.5 M and 5 M)? Worst case scenario I'll buy too much and discard any unused line, but that seems wasteful. Does anyone know the proper lengths and/or colors for these lines? Thanks!
