On CHANCE 1977 323 we start by putting  the mast in  the center of boat in mast collar  After that we start by running the main halyard with a 50 foot steel tape attach.  Then hoist to the top of mast and cleated.  Now take tape and measure  to the shroud pins attach to the turnbuckles.  This will center the mast then tighten to about 43 on a loos gauge 750 lb. keep checking with the tape to center the spar we end up at about 46 or 1100 lb . Tighten the lower front shrouds  first so the spar is straight ,going back and forth side to side keep it straight port to starboard set at 500lb. Next your aft shroud same as front shrouds at 500lb. Sheet your main boom in tight center on traveler . Now get off the boat and sight the mast  from the side 100 feet away, for forward and aft rake . Try to get the mast straight up and down by tightening the fore stay and back stay check pressure on your sheet does not affect the back stay easy out main sheet.tighten the back stay to about 43 or 750lb.  Now take a look at the mast check fore and aft try to get  straight as possible.  If you have roller furling or a foil the fore stay well only have to be set once not every year.  Now sail the boat ,take look up the spar that is straight no fall off the top mast and straight in mid section to top. my lowers are at about 1100 lb and upper also 1100lb.  I have and adjustable hydraulic back stay which is usually at 1000 lb  more if its above 20 mph .you will bend the boat so aft bins well not open if not careful .The sails cut for most boats other then high tech well have about 6" of fall off on the fore stay keeps the boat power up even J boats 3"or 4"  Pearson 323 is not a great pointing boat but reaches and down wind we do well  As i always say every boat has it day to win races!  Another thing I did was where the spreader is pin ,add  another 1/4" bolt to keep the spreaders from swing it works great the bolt is about  1 1/2 " from pin aft.   Bob K CHANCE OWNER 42 years!

@Chance, great info. There were a lot of numbers up there that seemed to change a few times but if I read your post right, I think in the end it looks like all of your shrouds are at 1100lbs and the back stay is at a minimum of 750 lbs with no sheet tension but can be above 1000lbs if it's above 20 knts.? Is that correct?
