Two Methods I use
The "Oldtimers" method. Take the boat out again, get it healing 20 degrees or so. While somebody minds the wheel, go forward and take the slack out of all the leeward shrouds, to just snug. Reverse course and do the same thing on the other side.The "Modern" method. Get a Loos guage and follow the instructions. With either method there's still a lot of work left to be done.When I step a mast, I start with all the shrouds very loose. Then I center the mast left and right by lightly tensioning the cap shrouds. A quick way to check is to adjust your main halyard so it just touches a point on the starboard toe rail, adjust your cap shrouds until it just touches the same point on the port toe rail. Most boats aren't perfectly symmetrical, but this is close enough for all but America's Cup Wanna-Be's.Next fore-aft rake is set by adjusting the head and aft stays. Your roller furler may not allow head stay adjustment, so you just tension the aft stay. The exact amount of rake is an art, not a science. I believe JCII said his dad intended the CH-33 to have about 6" of rake. Meaning, put a heavy weight on your halyard, and a bucket of water at the base of the mast. Dangle the weight in the bucket (the water dampens rope swing). Adjust rake until the halyard is 6" behind the mast.Next lightly (equally) tension the lowers. Check that all is in alignment. Frequently look up the sail track to make sure you don't have the mast bowing one way or the other. Now work you way around the lowers increasing tension a few turns at a time, frequently sight the track, check tension with a guage until the desired tension is achieved (Loos provides a guide based on wire diameter, also a very good web site to review)Likewise tension the uppers, fore and aft shrouds. Recheck the sail track, re-check rake.Now sail the heck out of the boat for a week to allow the rigging to stretch, then re-adjust.This is just a generalized how-to. Specifics vary boat-to-boat and with the needs of the sailor. There are many good books on the subject, I own several and use tricks from all of them. I suggest you start your own collection.
