to install DYI, you can even do it with the mast up! The hardest thing to do is unroll the plastic luff track and get it to stay flat. A couple of days in the hot sun should do it. Then you have to tie off the
jib halyard to the front of the boat and make it real tight so you can release the forestay. (it helps to loosen the backstay also) when you have the turnbuckle apart follow the instructions closely! You don't get a second chance if you cut the luff track too short! Again, the plastic luff track HAS TO BE STRAIGHT!
good luck!
