Does anybody have an idea of the laminates and orientations that are used to build these light-weight freestyle/freeriding hulls and decks?

Most use some type of carbon or carbon kevlar, the strong ones use both.

there is a hull builder who posts on this site. maybe he'll help you out...

hmm... do any of the hull builders use systems too advanced or expensive to replicate in your garage?
I haven't seen anyone using prepreg or autoclaves.
I think the biggest thing is knowledge and practice.

sergio vac bags his hulls. How he can build them so cheaply, and vac bag em, is still a mystery. Unless carbon is THAT cheap in brazil.

im looking more for the spec's of the laminates for example, weights orientations, resin ratios and hull and deck thicknes. I know this is info that most builders will not let out. But hopeing there maby one.:biggrin:
With all due respect, it sounds like you want to use someone else's research/testing without doing it yourself. The people that build hulls put a ton of time (at least most) into figuring out that information so they can build a strong and lightweight hull.

Vacuum bagging can be done affordably...
I agree with superjett. I highly doubt that the information you're looking for will be shared. A lot of time goes into developing a layup schedule.
as far as resin ratios the closer you can get to 50/50 the better
If you want a REALLY durable hull, you might want to look into using S glass and maybe some carbon/kevlar hybrid cloth in key places. Then use vinylester resin.
Even though a hull builder won't give up his hard earned secrets, there is a LOT of information on the subject available.

Cheers for the idea's guys, yes i agree that these are trade secrets and respect that. Just thort someone might have built one in the garage at home and might have some idea's. when i get my project underway ill post. what is S glass??

High-strength glass, carbon or other advanced fibers are used in applications requiring greater strength and lower weight. High-strength glass is generally known as S-type glass in the United States, R-glass in Europe and T-glass in Japan. S-glass was originally developed for military applications in the 1960s, and a lower cost version, S-2 glass, was later developed for commercial applications.
High-strength glass has appreciably higher amounts of silica oxide, aluminum oxide and magnesium oxide than E-glass. S-2 glass is approximately 40-70% stronger than E-glass.
