Why go carbon? All over the world Dinghy, Keelboat and Yacht sailors are enjoying the benefits of Seldén carbon spars for both racing and cruising.  Carbon masts are lighter: less weight in the rig increases righting moment and reduces pitching for more performance and more comfortable sailing.  Carbon masts are stiffer: improved control of mast bend improves sail shape and reduces forestay sag, more performance and higher pointing.  Carbon booms are up to 40% lighter: less weight in the boat and on the mainsail leech increases performance. Lighter booms have less momentum making for...

Cross section  Pre-preg construction: all tubes are made using 100% pre-preg materials. No wet lay-up is used. Autoclave cured for near perfect consolidation and void free laminate.  Seamless tubes: using a male mandrel makes a single piece tube. The need for vertical joins and joints using screws and filler is eliminated.  MFM: straight, thin filaments of carbon fibre are laid on a male mould. Fibre is applied under high tension to ensure straightness and a compact lay-up.  CNC: carbon is laid by a computer controlled head. Consistent, accurate, repeatable, no human error.  Autoclave...

Give us the facts At Selden every rig is specifically designed and engineered for each boat. We base our mathematical dimensioning on data supplied by the yacht designer using our ‘rig facts form’. This is used by our ‘Rigcalc’ team to calculate the righting moment of the boat which determines section size and rig loads. Every boat is added to a database which gives our designers an experience bank of over 10,000 rig designs. 100% Pre-Preg Carbon All our spars are made from pre-preg meaning that the fibre is coated in the precise amount of epoxy resin for optimum lamination. This allows us...

Shrink wrapping When the lay-up is complete the delivery head sheathes the mandrel/carbon combination in heat shrink tape. It is then removed from the MFM machine, enclosed in a vacuumed bag and prepared for the curing process. MFM is a process unique to Selden. Our custom made CNC fibre laying machines are fast, efficient and equipped with a delivery system designed and fitted by Selden to provide the finished spar with unrivalled accuracy and precision. The key stages of the process are: Winding An aluminium male mould is rotated on the MFM machine. A carriage travels next to the mandrel...

Natural: Dinghy spars and spinnaker poles are supplied with no additional painted finish. The resin system used in the manufacture of all our carbon spars includes a UV inhibitor to protect the epoxy resin. A black pigment is also added to the resin to further improve UV resistance. A natural finish and the limited UV resistance it provides is ideal for spars where weight and cost are critical. Seldén carbon spars are available with a choice of 5 quality levels of surface finish. Which quality you choose depends on the type of boat and the requirement of the spar. Standard Clear: In this...

Specialist fittings – booms Seldén ‘Y’ boom The Seldén ‘Y’ boom is a Park Avenue type carbon boom designed to allow easier reefing and sail stowage for the larger cruising yacht. Lazy jacks guide the sail on to the top of the boom while the beautifully shaped wings of the ‘Y’ boom help to catch and retain the mainsail when lowered. A sail cover is then zip closed over the top of the sail. Single line reefing and boom lights can be specified as options. ‘Y’ booms can only be supplied with a painted finish. End Fittings Inboard end fittings are machined aluminium. They have integrated slots...

Spinnaker poles A carbon spinnaker pole is a popular upgrade for both cruising and racing sailors. Carbon poles are up to 40% lighter than an aluminium equivalent. This makes them much easier to handle during hoists, gybes and drops, as well as reducing line loads on the topping lift. Selden carbon poles are available for boats up to 70ft. As standard they are supplied with a natural finish, clearcoat and painted finishes are available as an option. Protective Twaron wrap can be specified to reduce damage where the pole contacts the forestay. Selden gennaker bowsprits are available as an...
