Freethe bar by lightlytapping its end witha hammer. Place ascrap wooden blockagainst end beforetapping withhammer to avoidany damage to thebar.

Hall Spars 19Important:Your mast is stillrelatively untuned,so caution is advisedat this stage.InspectionOnce vertical shrouds are tight, make sure diagonal shrouds are “loose.”Your rig is now ready to tune under sail.Tuning Under SailUnder mainsail alone, check vertical shroud tension and transversestraightness of mast.On one tack, tighten leeward vertical shroud as tight as possible countingturns. Then repeat on opposite tack with an equal number of tighteningturns. Hand tighten lower (D1) to hold mast sideways centered at firstspreader. Unless mast is bending sharply, do not adjust upper diagonals(D2 and up) yet.Put up a number 3 jib or similar working jib and repeat sequence above.Check sideways bend.Repeat with genoa, if not too windy. The leeward shrouds should be firm,not floppy at 20° heel.Now adjust diagonals to straighten mast sideways.In early tuning stagesmast should haveslight leeward bend.(As uppers tighten,diagonals do too,and this bendwill slowlyreduce)1" - 2"

22 Hall SparsSail Control Bend<strong>Mast</strong> bend is used for sail control. All mainsails have luff curve whichcreates sail shape. With the mast straight the sail will have shape. If youbend the mast to exactly fit the luff the sail will be almost dead flat. Inlight to medium air — especially in a chop — use only a little bend and“power up” the main. In heavy air, bend the mast more and the sail willdepower allowing the boat to stand up better and be easier to handle. Agood rule of thumb is to limit mast bend deflection to amount equal tothe fore and aft dimension of the mast. (On extreme racing masts, thisnumber is regularly exceeded.)Little or no bend.Main “poweredup.”Maximum bend.Main depowered.

24 Hall SparsMaintenanceMAST:<strong>Mast</strong> should be unstepped at least once a year and inspected. Thefollowing lubrication should be done once a year.1. Remove, inspect, and lube sheaves (Harken sheaves do not requirelubrication).2. Remove headstay and backstay and inspect mast; clean and lube pinsand reinstall.3. Visually check alignment of shrouds in upper tang. Misalignmentespecially in rod is a cause of fatigue.4. Tip Cups: Remove set screws and flattened balls, unscrew collar.RIG LUBE ® threads. Screw on collar, reinstall set screws with newplastic balls.5. Turnbuckles: Note tuned position, remove cotter pin, totally loosen.Spray threads with RIG LUBE. ® Retighten to tuned position, insertcotter pin.Note: Easing and tightening turnbuckles must be done under sail unlessmast is fitted with hydraulic jack.6.1x19WireStays: Visually inspect swages for longitudinal cracks orwire strand failure at top of swage.7. Visually inspect spreader tips and roots for damage or wear.8. Inspect mast for sharp edges and silicone or tape as needed.BOOM:1. Check gooseneck lugs for cracks or hole elongation.2. Inspect vang and sheet bails.3. Inspect condition of outhaul wire.4. Check function of outhaul car. If it slides with difficulty call HallSpars for fix.


Hall Spars 25Care of CoatingYour spars are coated with AWLGRIP, ® a paint originally developed foraircraft. It is a tough paint with excellent gloss retention. But it can bedamaged. Here are some hints.Notes1. Use care when servicing mast. Cover areas adjacent to work area withcloth rags.2. Cleaning <strong>Mast</strong>: Use light detergent (SOFTSCRUB ® or similar - NOabrasive cleansers!). For especially tough grease smudges Acetone orToluol may be used if mast is over one month old (AWLGRIPÒ fullycured).3. Touch Up:-Small scratches: using AWLGRIP ® touch up kit available from HallSpars, mix parts 1 to 1 and apply carefully in scratch with modeler’sbrush.-Large scrapes: repair should be done by professional painters usingAWLGRIP ®(A paint scratch is a cosmetic problem with no danger of corrosionleading to structural damage. If metal is gouged, call Hall Spars foradvice.)4. Paint bubbling at stainless parts: This will happen sooner (in southernclimates or marinas with imperfectly engineered electricity) or later.Merely sand bubbled area and touch up or respray. Again this will not bea structural problem unless aluminum is excessively corroded.
