Never use an extended piece of pipe on the handle of a wrench because you will over tighten the rigging and do damage to the turnbuckle . Relatively speaking, the cap shrouds should be tighter than the intermediates because they are longer and will stretch more under load. Tighten the backstay to the maximum tension you will use while racing. At this point you should have the maximum amount of mast bend for your boat. If you don t have enough bend you can ease the headstay or move the mast either forward at the partners or aft at the step.
Mast bend is the maximum distance between the halyard and the mast.
Now it s time to go sailing. Put the boat hard on the wind in at least 10 knots of wind. It s a good idea to have enough crew to handle the boat easily. Use a non-overlapping genoa so that tacking is quick and easy, you'll be tacking a lot while tuning. Before you start tightening the shrouds, take a look at your mainsail.
