ADJUSTMENTS, RECOMMENDATIONS- when the lower shrouds have been tightened and theintermediate shrouds adjusted , the pre-bend valueshould be approximately half the mast section depth(about 10/12 cm for a 35'). This value can increase toone mast section depth if required;- adjust the running backstays to finish, as they work inopposition to the rest of the rig;- when the back angle of the spreaders is below 15°, the tension requiredon the running backstay is high, in order to support the mast backwards;- If the rear angle of the spreaders is above 15°, the spreaders will alsosupport the mast lengthways and the tension on the backstay does not needto be so high. However, be careful not to exceed the limit to avoid a mastinversion.Tension of fractional rigging within-line spreadersmini1/2 L.max1 L.13.5- proceed as in section 13.3. Note:- The rigging with in-line spreaders is adjusted as withtop rigging, the only difference being theaddition of backstays for the tension of the forestay;- The mast should always be adjusted with acertain bend forwards/backwards, otherwise thecurve of the mast may be invertedparticularly in strong winds.Avoid a negativebend (“curvedbackwards”)the babystays adjust the bend of the mid-sectionof the mast. If they are too tight in relationto the backstays, they can cause theinversion of the mast bend.www.sparcraft.com / 19
14ADJUSTMENTS AND SEA TRIALSChecking adjustments under sail- check the adjustments in moderate or light winds on calmseas. It is preferable if you can avoid having to deal withmanoeuvres by taking aboard some experienced crewmen;- check the alignment of the mast upwind looking along thesail track (lateral alignment) which should be straight onboth tacks;- the leeward cap shrouds should not be completely slack.If this is the case on both sides, take in (once moored ashore) the samenumber of turns on each side of the mast. Redo the adjustment as manytimes as necessary until fine-tuned.N.B.: a new rig requires an additional adjustment after its first sailingtrips.Too slackToo tautToo slackTootautToo slackSide adjustmentDiagonal adjustment (intermediate shrouds)Remarksconcerning discontinuous rigging:- before applying tension to V1D1, it is imperative that you ease thediagonals first.N.B.: some classes of yacht have their own specific information concerningthe tension of the rigging.
