Series constructions

The Witchcraft Series constructions are another part of the revolution for production boards:

* Inner strength. Buying a board is investing in a good time on the water, in the healthiest drug in the world, in stress-relieve and not to cause stress. We want your board to last. This is why we pay as much attention to making the inside of the board as strong as the outside to avoid invisible internal damage or fatigue

* A board is only as strong as its weakest component. All of our constructions are very efficient by carefully choosing materials and lay-up with a similar elasticity so they all work together in harmony. Witchraft has developed and fine tuned board constructions over many years to try to avoid practically all damages, as much as technically is possible.


Construction

There are 2 constructions available.
SDT - H-glass (50%), Carbon (15%), DyneemaŽ (5%), epoxy, single-double-triple sandwich
- 1 year guarantee*
HDD - -DyneemaŽ (60%)-Carbon (15%)-glass-epoxy-single-double-triple sandwich, Witchcraft's famous Heavy Duty DyneemaŽ construction with 18 months guarantee*. With full Dyneema on top and bottom, overlapping on the rails. Another first from Witchcraft, the specialists in full Dyneema boards for over 10 years.
- 18 months guarantee*

About H glass

H-glass is a new patented microscopically hollow glass fibre. It is 40% lighter and 32% more pressure resistant than traditional e-glass, usually the cause for board breaking. H-glass based composites also serve as a very efficient shock absorber. After Dyneema we found this the best material to use in wave boards, especially for spots without rocks it is a very good alternative.

About Dyneema

Since 1994, under the tough demands of the conditions on Fuerte, Witchcraft started using DyneemaŽ fibre as the main fibre in their boards. Dyneema* is the strongest fibre on the market. It is very light, even lighter than water but has a very high tenacity and energy absorption. Still it is stiffer than Kevlar and glass fibre, being slightly more flexible than carbon. It also has a long flex life and is not brittle as carbon or glass.

Apart from the price, the problem with Dyneema is that it is hard to work with, hard to cut, to sand and to laminate. It requires high quality workmanship, since irregularities cannot be corrected afterwards. With Dyneema it is nearly impossible to puncture the board. On impact there may be a dent which can be heated out with a hairdryer or hot air gun, since the sandwich material we use has memory and returns to it´s original shape over 70° C. On heavy impacts, the thin layer of glass fibre covering the Dyneema for the finish, may crack, the Dyneema will usually still be intact to stop water penetrating the board. Witchraft has also developed various secret construction "tricks" on the inside, to make boards stronger and to prevent fatigue, that are quite simple but very effective. Witchcraft does not use T or Delta stringers, instead the Witchraft solutions are much more efficient and stronger. Wood is in principle not a bad material for weight/strength/price ratio however it also has a few flaws which is why we don´t use it:
* It is only strong in 1 direction so when pressure is applied it will just break along the weak line.
* It is also a completely different material with a different elasticity than the other materials used therefore losing a lot of it´s efficiency.
* It can´t be bend around the rails.
* And it can absorb water, inch or start rotting.

But, Witchraft does not want to reveal too much here, you´ll have to take our word for it and let our guarantee conditions convince you. Witchcraft is also the first company to actually reveal the amounts of different fibres used in their boards, which has been common for masts for many years. All this results in a superior board with the highest strength to weight ratio possible, truly ``Witchcraft``.

*Functionality first: All boards are equipped with G10 Witchcraft Trifins, one colour ergonomic pads, Pro Limit ergonomic straps, four screws per strap, sidefin boxcovers.
