This is the initial and recommended maximum tension used for tuning & heavy air sailing. After making adjustments to other shrouds re-check the tension and adjust the rig adjuster if needed. In lighter air the rig adjuster is eased off allowing a more full sail. When the rig adjuster is eased the pre-bend is reduced and the diagonals go slack.

This is the mast tip control. This is left with less tension to allow the top to bend off in a puff.
This initial maximum tension is used to adjust the other shrouds. This should be re-adjusted via the rig adjuster after each adjustment is made to the other shrouds.
