While my beloved Port Admiral was in corporate training on Saturday, I spent time re-rigging some things I was a little dissatisfied with:
First - I replaced spinnaker halyard with a longer one. The crew had been commenting that the halyard wasn't long enough to get the head of the sail back into the turtle. The end of the halyard is connected on a 1:2 purchase. I run the halyard through a Harken microblock which is attached to the line I haul on to raise the sail, to a shackle on the keelson near the mast. The halyard is attached to the shackle via an eye made in the halyard by making a loop and sewing it together. I left the bitter end long in the event the halyard shrinks.
Second - I took the old Spinnaker Halyard and used it to replace the topping lift which was chafing through.
Third - I used the old topping lift and re rigged the main cunningham using a 3:1 purchase with some 16mm airblocks. That cascades with the 2:1 I get from the cunningham going through the cringle to a point where it is made fast to the mast.
Fourth - I added a cascade to the Boom vang, so now I have a 12:1. Took another proctor boom slide car placed it ahead of the existing boom vang slide car, and fastened a line to it that runs to a Harken micro block that is attached to the mast by a U shackle. After the line pass through the block, it continues to the 6:1 purchase I originally had on the boat.
I set the mast up, hoisted the outboard end of the boom up to its maximum by attaching the main halyard to the outhaul. I lengthed the 6:1 vang to it's maximum and temporarily attached the cascade. From that, I was able to determine the length of line required. I lowered the boom to its minimum, and tightened up the vang. It didn't go two-block, so I was happy.
Now, I get to try to it out on Wednesday!
