aluminium masts all seldén dinghy mast sections have been designed to give the best stiffness to weight ratio available in an alloy extrusion material section shape and size and wall thickness all have a major effect on both the static and dynamic bend characteristics of a tube these details are studied in the design of every section and are carefully checked on every piece of spar tube we use selecting the correct section to suit your class and your specific crew weight and sail cut is vital please don t hesitate to refer to your class data sheet on www.seldenmast.com for further details or contact your local dealer for advice current sections mast section section weight kg/m c060 0.78 dimension fore/aft mm 61 dimension athwart mm 50 stiffness fore/aft cm 4 10 stiffness athwart cm 4 7.5 suitable for 2420 cadet feva snipe vaurien electron c061 1 59.5 66 12.2 17.9 splash flash lambda c063 0.88 63 51 13.6 9.8 mirror vaurien teeny c c065 0.9 65 54 14.1 9.8 lark solo firefly kappa c067 0.92 67 55 16 12 420 flying junior e c070 1.15 69.9 53.9 18.9 13.7 flying dutchman wanderer wayfarer 420 470 505 albacore hornet fireball scorpion solo rs200 rs400 gp14 laser vago 470 505 fireball cumulus c069 1.04 70.5 58.7 20.41 14.37 alto c071 1.073 70.5 59.5 21.5 14.97 d plus c074 1.07 72.9 57.2 20 13.8 enterprise solo epsilon c072 1.09 72 57 21.8 15.6 flying 15 470 osprey pirat rs vision flying dutchman nomad topper omega gamma c075 1.25 75 57.4 27.1 16.9 discontinued sections mast section section weight kg/m c073 0.97 dimension fore/aft mm 72.9 dimension athwart mm 57.2 stiffness fore/aft cm 4 19.5 stiffness athwart cm 4 11.8 suitable for d 505 f c078 1.35 78 60 30 20 bosun kzv corsaire our older types of masts are no longer in production but we stock a comprehensive range of spare parts and accessories for these masts 7

top tapering step by step seldén has invested in the most advanced manufacturing methods for tapering aluminium spars starting with the highest grade 6082 aluminium alloy extrusion our automated four-step process ensures not only the best performing mast but also an unparalleled level of consistency in every tube 1 plasma-cut taper our investment in cnc controlled technology has allowed us to produce the most consistent tapered masts available the plasma cutting process ensures a smooth edged perpendicular cut that is 100 accurate time after time reducing the inconsistencies that are common with a manually prepared spar this process also provides us with the ultimate product development tool the dimensions of the mast taper can be adjusted to suit high-end performance requirements simply by modifying the cnc program 2 automated welding the automated welding process joins either side of the taper together in one continuous and controlled sweep this helps eliminate weld variation and localised hotspots keeping excess heat out of the taper this provides greater consistency and performance from the mast taper the weld produced is so perfect there is no need to mechanically grind the weld again reducing the possibility of creating inconsistencies in the mast section 8

3 heat treating and bead peening all masts are heat treated in our purpose-designed oven this hardening process ensures that you get maximum performance from the tapered section our purpose-designed bead peening machine provides a uniform cleaning process and does away with hand cleaning or grinding further guaranteeing consistency from mast to mast this process also improves the fatigueresisting properties of the mast providing longevity and giving the seldén spar its distinctive satin finish 4 the finished anodised product tapered anodised and ready to be assembled using seldén s custom-designed fittings ready to win 9

carbon masts the investment in a sophisticated carbon filament winding machine and autoclave at our uk plant has enabled us to produce a new generation of carbon spars the following steps ensure that seldén can manufactures the best performing and most consistent spars on the market in-house specialist design team seldén has the design expertise and software to enable us to create a mast to meet exacting performance requirements during the design process the position and alignment of each fibre is precisely calculated so as to meet the required bend characteristics this detailed design is then used to program and control our filament winding equipment the combination of meticulous care long experience and exact specifications enable us to achieve optimum performance for minimum weight computer controlled laminate lay-up carbon filaments are wound around a mandrel male mould under controlled tension via a designated winding program supplied by the design team filament winding a computer-controlled process cnc guarantees consistent and accurate filament fibre orientation from spar to spar carbon filaments can be laid from 0° uni-directional to leave 89° hoops and at all angles between to produce a wide range of bend characteristic requirements this accurate alignment of composite filaments is vital to the performance character istics of a carbon spar fibres are laid under tension which means that we can make the most efficient material choice and supply the lightest spars on the market this process gives a seldén spar a level of tube consistency unattainable via any other composite manufacturing technique hence the mast you buy will perform as well for you as it will for a world champion sailor 10

use of pre-preg carbon only the highest grade pre-preg tows of t700 or tz carbon fibre are used to give sailors the best stiffnessto-weight spar this in combination with our filament winding process enables the highest fibre-to-resin content pre-preg to be used the aerospace grade pre-preg has a uv stabiliser in the resin system to give the spars a guaranteed long life even in the sunniest of climates more fibres and less resin mean lighter stiffer masts autoclave cured the consolidation of the material to form a ready-toassemble carbon tube is completed in our in-house 20-metre long autoclave the combination of heat and pressure to cure the resin and consolidate the pre-preg material ensures a strong and consistent final product carbon mast section section weight kg/m 0.511-1.008 dimension fore/aft mm 54 dimension athwart mm 54 eiy gnmm2 6-19 eix gnmm2 6-14 suitable for series ii cc054 contender merlin rocket national 12 phantom ok rs800 orbis cc059 0.42-0.64 60 60 8-23 8-23 series iii cc064 0.43-0.65 66 52 10-16 7-13 59er contender fd int canoe international 14 merlin rocket musto skiff phantom artemis 20 backman 18 18ft skiff skud series iv cc077 0.83 81 63 28-31 18-23 note that we are highly flexible with our laminate designs so we can customise laminates for particular classes not for individual customers use of higher modulus fibres will allow us to exceed the above properties 11
