Halyard routingHalyard boxesWell thought out routing of halyards not only reducesfriction, but will also prolong rope life. It makes for safeand fast sail setting and dousing, equally important forthe cruising sailor as well as for the racing sailor. It’s allabout quick and controlled sail handling.Seldén halyard boxes for halyards and spinnaker lift aredesigned to satisfy very high demands for functionality,strength and light weight.Halyard leadThe single halyard lead guides the halyard vertical andinto the halyard box. It prevents chafe on the halyardand on the halyard box. The location of the halyard leaddetermines the maximum spinnaker hoist. The Seldénhalyard lead is U-shaped, hence it can be retrofittedwithout pulling out the halyard from the mast. Thematerial is chromed bronze which is kind to a wirehalyard. Of course, the lead works well with ropehalyards too. Two halyard leads can be fitted side byside to handle two halyards.Halyard routing is particularly important when a jibfurling system is fitted. It prevents the halyard wrappingaround the luff extrusion when furling or unfurling thesail. A so called halyard-wrap can seriously damage thefurling system, the forestay and the halyard.0 210 mm5-1QWHalyardThe double halyard lead fitting consists of a stainlessbracket with two integrated stainless rings. The brackethas the same radius as the front of the mast. The ringsare well rounded and have flared entry/exit for minimumfriction, promoting fast spinnaker handling.EDouble halyardHalyard exitA halyard exit is used to lead the halyard out of themast and further down to a cleat or a block at decklevel. The fitting prevents chafe between a halyard andthe cut-out in the mast. The location of exits is a veryimportant factor in smooth and effective halyard routing. They must be located with a certain distance fromeach other, not to weaken the mast and at the correctheight for effective sail hoisting. Seldén has a standardset-up for halyard slots, but we will incorporatecustom solutions to suit to a specificdeck layout.To prevent corrosion, all fittingsmade of bronze or stainless steelare insulated from the aluminiummast section. With carbon fibremasts the insulation protects thefittings from corroding.RHalyard exit21

Spreaders and spreader bracketsAluminium sections C080-C096 and carbon CC077CC095 feature external stainless spreader brackets.These fittings feature a wide base to transfer spreaderloads to the mast extrusion. This makes for a rigidconnection, low windage and low weight.The spreader brackets are angled 6 for optimum rig support.C080; CC077With the clevis pin vernier adjuster system, the spreader angle can be set anywhere from 0 to 34 , with adjustmentincrements as small as 2 .

Sail entryThe sail entry is a smooth stainless fitting and acceptsboth bolt rope and sliders. Combined with a prefeederfitted to the boom bracket, hoisting a sail with bolt ropebecomes really smooth. For sails with sliders, a springloaded feeder is inserted in the luff groove.The feeder allows for the sliders to pass the sail entryand all the way down to the boom bracket when the sailis reefed or doused. To select the correct size slider,please see page 10.Sail entry505-533-01Spring loadedfeeder for sliders505-534-01600Pre-feederfor luff rope505-538-01Top ofBoomFeeding a sail with sliders1) Feed all sliders into the sail entry.2) The sliders will pass thesail entry all the way down tothe tack.3) The sliders always connectthe sail to the mast, simplifying hoisting and reefing.Feeding a sail with luff rope1) Tie the pre-feeder to the boom bracket.302) Feed the luff rope into the sail entry.3) Hoist the mainsail.

Deck-stepped mastsLoad distributionA convex heel plug at the lower end of the mast sectionallows the mast to be raked 3,5 aft and 1 forward, andstill evenly transfer compression load to the mastsection. This concept is far from new but nevertheless,brilliant. It was introduced by Seldén early 70’s.3.5 1 Convex heel plug distributes compression load evenly on themast section.It is easy to step the mastThe aft end of the heel plug is connected to the T-basewith a clevis pin. This clevis pin works as a hinge andallows for controlled raising and lowering of the mast, agreat help for sailors who frequently un-step their mast.For the owner of a trailer boat the advantage is obvious.31

T-base, heel and attachments for deckblocksRopes leaving the mast through halyard exits continuedown and then lead aft to clutches, Cam cleats orValley cleats located within reach of the crew in thecockpit. The mast stands on an aluminium T-base,which is bolted to the deck. Six stainless attachmenteyes, three on each side, can be fitted between theT-base and the deck for attachment of lead blocks.This enables ropes to be efficiently routed to thecockpit. In addition, the T-base comes with two centreline attachment loops, one forward and one aft. Theseloops are mainly used for spinnaker pole downhaul andthe kicking strap.T-baseLoop for spinnakerpole downhaulAttachment eye forhalyard blockMast heelMast heel without sheavesMast sectionAluminiumCarbonC080CC077Heel plug,Art. no.T-base,Art. no.Attachmenteye,Art. no.Loop,Art. no.LmmWmmAmmBmm502-560-01 510-158-01--100351040502-560-02(sheaves) 510-155-01--15040744 2-566-01(adjustable) 510-171-01**Including attachment eyes and loops.QWT-BaseLAREARDWVerAsion 4DECK HSELDÉNBACDECKHARDWARELWB32T-Base, attachment eye and loopLWBERAdjustable T-baseBCWAB1Read more about Seldén’s blocks,Cam cleats and Valley cleats in ourDeck Hardware catalogue, art. no.595-905-E.Attachment eye,Art. no. 508-497Loop,Art. no. 508-459

Mast heel with integrated sheavesHalyard ExitsAn alternative to halyard exit slots is to run the halyards outthrough the mast heel. Seldén offers this solution by adding afitting with four integrated sheaves between the mast sectionand the heel. The sheaves are fitted in adjustable cages that canbe individually angled towards a deck organiser or direct to aCam Cleat in the cockpit area. In the top of the stainless cages,rubber o-rings preserve the cage alignment when the rope isunloaded. They also prevent rattling.70 SpinnakerhalyardSpinnaker liftJib halyard90 Main halyardBall bearing sheaves are available for some of the sections.When needed, additional attachment eyes and loops can befitted underneath the T-base.Mast heel with sheavesMast sectionMast heel with fourplain bearingsheaves, Art. no.Mast heel with fourball bearing sheavesArt. no.Aluminium/CarbonHeight of ropesabove -C139CC138502-566-02/-52-522 sheaves each side.Stainless holder,70-90 articulationRubber O-rings toprevent rattling.Hinged heel plug as standardLoop for spinnaker poledownhaul attachmentLoop for kickerattachmentEyes for block attachments33

Keel-stepped mastsThe aluminium deck ring comes with six stainlessattachment eyes, three on each side. Blocks forhalyards are attached to the eyes to lead ropes back tothe cockpit. There are also two stainless loops fitted tothe deck ring, one forward and one aft. These are intended for the spinnaker pole downhaul and kicking strap.A keel-stepped mast has, as standard, an internal sealin order to minimise water leaking into the bilge. Thecable conduits are open to simplify installation ofadditional cables but they can be sealed afterwards ifrequired. Externally, a flexible mast coat prevents waterleaking through the deck.The mast is secured in the deck ring by rubber wedges.To prevent lifting the deck by the halyard loads, Tierods are fitted in backing plates in the mast section andconnected by rigging screws to attachment loops in thesolid deck laminate.Deck ringMast sectionT-Base,Art. no.Deck ring includingattachment eyes,loops, backing platsfor Tie-rods andrubber wedges,Art. no.Mast coat,Art. no.Hose clip,Art. no.Attachmenteyes,Art. no.Loops,Art. no.Rubber wedges,Art. 42 x 530-2391 x 530-240C139CC138-530-0652 x 530-239533-034-01530-063312-202508-497508-4592 x 530-2392 x 530-240Drainage holeMast coatTop of Deck220Tie rod backingplateTie rod arrangementDeck ringRubber wedgesSail grooveMast section34Cable conduit
