A light East/Northeasterly below 10 knots with near flat seas this morning.
Try the inshore grounds from West Beach to Glenelg for whiting.
Seldens carbon spars are currently being used on Flying Dutchman, International 14’s , Contender and the Musto Skiff . Selden are also working closely with various classes and they move to allow carbon to be used . . Like wood and alloy previously, initial attempts at spar manufacture took place with round tubes, where technology quickly allowed masts to evolve into profiled sections.
Seldens carbon spar range features super efficient ‘profiled’ shapes. The ‘Tear-Drop’ profile gives the spar the required stiffness ratios fore and aft to counteract the upwind kicker loads. Also, because of its aerofoil shape, the profiled section has improved air adhesion compared to a round tube, meaning that the spar will directly increase lift and reduce drag and so allow a cleaner air entry onto the luff of the mainsail. In real terms, this means the boat can point higher and go faster!
"The Seldén carbon dinghy spar range, with its unique profiled section, truly offers a new generation of carbon performance spars".
|Series 3||0.47-0.65||64||52||18-27||15-23||Contender, Int., Rocket, Musto Skiff|
|Series 4||0.68-0.88||79||62||27-41||23-34||International 14, K19|
|Orbis||0.43-0.56||60||60||16-24||15-23||B14, OK, RS800|
Step Down System
"A ‘step-down’ tapered topmast system, where the compression loads in a rig change immediately above the hound and/or trapeze point, has also been built in to each spar to provide ultimate mast tip control."The topmast will automatically respond through gusts and lulls, as opposed to the mast hinging around the hound point and producing an unbalanced rig - as typically occurs with traditional alloy rigs."
Chips goes on to explain, "no more ‘fighting’ the boat through the gusts and lulls, the topmast will work to your advantage allowing the boat to effortlessly accelerate through every gust. Computer controlled automated laminate lay up under controlled tensions gives Selden a level of tube consistency unattainable via any other composite tube manufacturing technique. Hence, the mast you buy will perform exactly the same as the World Champions!"
Only the highest-grade pre-preg tows of T700 or TZ carbon fibre are used to offer the sailor the best stiffness to weight spar, and with filament winding, the lowest resins to fibre content pre-preg can be used.
The aerospace grade pre-preg has a UV stabiliser within the resin system to give the spars a guaranteed long life, even in the sunniest of climates. In addition to the spar section, a custom-made track has been shaped to extend the profile. It is extruded from a highly advanced plastic that offers excellent heat & UV stability, and very high wear resistance.
The alignment of composite fibres is central to the performance characteristics of the spar. Filament winding is a computer controlled process (CNC), guaranteeing consistent and accurate fibre orientation from spar to spar. Fibres can be laid down in a series of layers ranging from 0º (unidirectional) to 89º (hoop). This allows the designer huge scope for tailoring the main and topmast section characteristics. The fibres are also laid under tension, which enables us to provide the most efficient material choice and the lightest spars on the market.
