Luff extrusion adjustment
Checking luff extrusion tension prior to stepping the mast
Theluffextrusioniscorrectlytensionedbeforeleavingthefactory,buttensioncanbere-checkedbeforestepping
themastinthefollowingmanner.
Laythemasthorizontallyonit´ssideandkeepitstraight.Theluffextrusionshouldnowbejustclearoffthemast
wallatitsmidpoint.Ifadjustmentisnecessaryseepoints1-5below.
Ifadjustmenthastobemadeafterthemasthasbeenstepped,thentheluffextrusionshouldbesotensionedthatit
doesnotbeatagainstthemastwallwhenyougraspitthroughtheupperaccessholeandshakeit.
Theluffextrusioncanbetensionedalsowiththesailttedifthewindsareverylight;Rolloutthesail,lowerit
slightlyandremovethetackfromthetackhook.Hoistthesailsoitdoesnotinterferewithtensionscrew.
Partoftheextrusionwillberestingontheaftfaceofthesailcompartmentwhensailing.
DONOTOVER-TENSION!Aluffextrusionthatisover-tensionedwillrequireincreasedfurlingeffort.

Releasethelockingscrew!3turnsandliftthelockingring".Lockingringcanbetemporarilysecuredby
apieceoftape.
Lubricatethetensionscrewwithriggingscrewoil(art.nr312-502).Putascrewdriverinthesailgrooveofthe
luffproletopreventitfromrotating.Apieceoftapeonthetipofthescrewdriverpreventsdamagetotheluff

Ifin-mastfurlingmastistobeoperatedfromthecockpitanendlessreengline(loop)incombinationwithaself-
tailingwinchisrecommended.Reenglineshouldbeø10mmpolyesterrope.Theendlessloopmusthaveextra
lengthtoallowittobeeasilyremovedfromthewinch.Thetail-endoftheloopmustalsobebelayedonastopper.
Onmostinstallations,thereenglineneedstobefedthroughblocksandstoppersbeforemakinganendlesssplice

themastusingawinchhandleatthemastlinedriver.Inthelattercasetheouthaulistakentotheboomormastnear
thegooseneck.(SeeFig.7.1).
Unfurling
Whenunfurlingfromthecockpitthelinedrivermustbesetto”free”.(SeeFig.7:2).
1. Freebothsidesoftheendlessloopfromthewinchandstopper.Itwillthenslideonthelinedriver.
2. Pulloutthesailwiththeouthaulline.
Furling
1. Theleechshouldbekeptfairlytightwhenreengorfurling.Adjusttheboomangle(vangortoppinglift)
 toachievethis,andthesailwillformatightrollaroundtheluffextrusion.
2.Locatethestarboardpartoftheendlessfurlinglineonthewinchandpullbyhand,orifnecessaryusea
 winchhandle.
3. Keepslighttensionontheouthaulwhiledoingthis.Thisappliesespeciallywhenthewindisabaftthebeam
 orinlightair.
Reefing
1. Carefullyslackenofftheouthaulline.
2. Locatethestarboardpartoftheendlessfurlinglineonthewinchandpullbyhand,orifnecessaryuseawinch.
3. Theleechshouldbekeptfairlytight.Keepslighttensionontheouthaulduringthemaneuver.
Whenworkingatthemast:
Activatethelockonthelinedrive(-IN’)beforereengthesail.Useawinchhandletofurlthesail.When
thedesiredamountofsailisrolledin,usetheouthaultostretchthefootofthesail.Don´t leave the winch
handle in the linedriver!
Whenoperatingfromthecockpit:
Whenreefedtodesiredsailarea,lockbothpartsoftheendlesslinesinstoppersandtightentolockthereeng
winch.Finally,tensiontheouthaul.
When leaving the boat.
Alwayslockthelinedriverwiththeratchetleverwhenleavingtheboat!

Maintenance of the in-mast furling mast
Periodic Maintenance
Maintenanceshouldbeundertakenatleastonceayear.Morefrequentcleaningforremovalofsaltandsand
isdonebyrinsingwithfreshwateronly.AllbearingsshouldbegreasedwithGREASE(PartNo.312-501),
atubeofwhichisdeliveredwiththemast.ReadthefollowinginstructionsandseeFig.13:l.
Whengreasingbearingsandgears,donotover-grease.Athincoatingofevenlyappliedgreaseissufcient.
TOP SWIVEL:
Thebearinghasalubricationholemarked”GREASE”wherethegreaseshouldbeinjected.Accessthroughthe
sailslot.
HALYARD SWIVEL:
Lubricatetheswivelbyinjectinggreaseintothegaps& inthering.Thisisbestdonethroughtheupperaccess
