It is difficult to repeat shroud settings without a Rig Tension gauge but most dinghy owners do not possess such a relatively expensive tool. The purchase of a Tension gauge can only be justified if you are racing the Xenon and only then if your performance puts you at the front of the pack.  For this reason the Shroud settings described in this Guide do not quote Rig Tension gauge values. Instead the settings are based on the distance from the gunwhale fastening ring and assume a standard Xenon shroud wire length. The top hole of the Main Shroud plate (HA4472) is 95mm above the gunwhale fastening ring. Hole spacing is 9mm.
The top hole of the Lower shroud vernier plate (A4272) is 115mm above the gunwhale fastening pin. To achieve this length the length of the A4272 has been extended by the use of a long ‘D’ shackle.
The hole positions quoted are from the topmost position downwards, eg. Hole 1 is the top, highest hole, in the Shroud adjuster. The measurements are given in case your shroud adjuster setup differs from the above and therefore you may need to use different hole settings to achieve similar lengths.

 
A useful alternative to a rig tension gauge is a marker strip stuck on the rear of the mast, alongside the Jib tensioning hook. As the Jib wire is tensioned the hook moves lower down the marker strip. This device will enable the crew to repeat the level of tension used in previous outings.
