Ah... one, in both PHRF and under the one design rules, you aren't supposed to change your rigging tension after the prep signal.
Two, your tension isn't changing, the rig's loading up. On any conventional stayed rig, when you go upwind, the rig loads up on the windward side, and unloads on the leeward side. That's fully expected. On most boats, properly tuned, the lee lowers go sloack when your properly powerd up and heeled over, and the uppers get softer as well. A fair bit of the load generated by the sails is lateral. (Hey, that's why boats heel, pretty much) All that load's pulling against the windward shrouds and towards the leeward ones.

Originally posted by Sultan: ...we meassured them and confirmed that they lost tension (from 40 before the race to 32 at the end of it)...
Just a thought - if you measured without the backstay loose, it will make the lowers slack more. Was the backstay fully slack for both measurements? If it was, you have some serious issues with your rig moving. Check things like base of the mast not locked in place or more seriously pending failure such as attachment points (chainplates, fittings on shrouds) etc. Moving from 40 to 32 is a whole bunch of turns on the turnbuckles!
