I want a surfboard that won't snap when kite surfing (strapless). Guess I want a cheap second hand epoxy board.
Having never just surfed, I know very little about surfboards..
Are there different strength epoxy boards?
Are tough light boards tough enough?
If a board is epoxy and fibre glass is it likely to be stronger or weaker than one that just says its epoxy?
How much glass would you need on a non epoxy board to make it tough enough to handle kiting airs etc?
(I keep snapping scrappy old $50 to $100 6'2" regular surfboards. But only cheap second hand boards are an option for my budget.)
PS read the other current threads on 'what surfboard should I buy' type stuff, but want to understand toughness better so i'm informed when buying a cheap but very strong board. Cheers.
Technicly speaking Epoxy boards all have fibreglass, boards are foam covered in fibreglass and laminated with resin (top ones being polyester vinylester and epoxy)
Epoxy boards aren't "tougher" than Polyester boards. The differences are in the fact that one is a better "binding" agent than the other and there fore allowing the Fibreglass to have a better mechanical bond to it's self and the foam as well as better properties for the resin infused fibre.
One of the main issues with surfboards is denting. This isn't actually a bi product of the fibreglass not being tough enough but the low density of the foam. Which is why people like tuflight (and a couple others) have a low density eps core with thin high density core around it.
There's lots of different epoxy board styles out there
Fibreflex - eps core carbon uni's on the rail for a parabolic stringer epoxy resin $900
Surftech (and a couple others)- eps core wraped in a thin higher density core epoxy resin $900
Firbreflex - eps core with balsa rails for a parabolic stringer epoxy resin $900
Standard - eps core with epoxy resin no stringer
Mine - eps core carbon with epoxy no stringer
(can't remember name) - eps core ply parabolic stringers epoxy
and the standard centre stringer with eps and epoxy $700-$900
It's hard to say which is "best" there's stories of people breaking all of them. I generally put about 2 x the reinforcement (glass or carbon) than I would on a regular surfboard.
Theres a guy that does custom boards with eps epoxy and a centre stringer for kiting in Aus I'm on the spot so I can't remember his name but he does the boards for the winners of the wave nats I believe.
