lol liam, his surf style is prob like watching granny porn and for the channels, idk about the flex, I think it adds strength similar to how bent steel or an I-beam is structurally sound, I could be off, any engineers out there offer an opinion? and Stretch KNOWS the PERFECT spot for fins when shaping a quad
"deck or rail channels are to surfboards what corrugation is to cardboard. Stiffens it up and makes it less likely to break. Hitlers personal airplane in the late 30's, the Junkers G 24 or JU-52, had corrugated aluminum skin covering, strengthened and firmed up the aluminum." -found that on another surf forum.
So one says the channel rails stiffens up up board, others say it adds flex. And a third states he actually had a thought. So which is it?? Okay guys....if that isn't marketings effect on crash dummies, I don't know what is. I win!!
engineering and common sense would say it alters flex and adds strength. you win all right...you win this helmet to wear around while you are walking in public
imo, the boards are legit...but the logos looks like sh!t. Just the main "S" logo is really bad and needs an update. On top of that, I don't know if I could deal with having a lil buddy" masturbation hand logo on the bottom of my board...it's below the line of class...and not in a cool way.
A single groove does not add strength nor flexibility. It needs several to be in series, parallel to each other, to be considered "corrugation". That is the definition from engineers, which you are not. As for common sense, it says the exact same thing. You lose again. What is your helmet size??
I have two of the Fletcher F Quad Fins. I like them both quote a bit. I do not get out on them, as much as I would like, but they are quality boards. I have them in PU. One is slightly too big for me so I almost permanently loaned it to a buddy who is a bit bigger than I. They go well and as a four fin in the steeper more hollow stuff they are good. Deck channels definitely help when duck diving in bug surf.
There was a guy in Tofino, Canada that was adding those deck channels on his boards under the "Addiction" label (I think he's shaping in France now). I first saw this about 12 years ago and although it looked cool, I didn't really understand the theory. I still don't. I've seen so many fads and theories since I started surfing in 1977. Picklefork noses, asymmetric designs, micro-groove channels, Aipa "stingers" with step-bottoms, MR twin fins, Astro Deck, PendoFlex, BLEF fins, etc. Pretty much the only things that have withstood the test of time has been the Morey Boogie and Simon's Thruster. Seriously, I personally don't see these rail channels as anything that will change the shape of surfing or surfboards. OTOH, I've gotten my hands on a few Stretch boards but have never ridden one. They are really great shapes with some of the best foil I've ever seen. And what everybody has been saying about Stretch quads is true...he appears to be one of the most experienced quad shapers on the planet. I'd buy one of his boards just on those qualifications alone (rail channels notwithstanding).
is an I bean corrugated? is bent steel corrugated? are they both stronger ? are there 2 channel rails (more than 1, a series makes) dont think to hard, your brain may swell and then you wont be able to take off your helmet.
Go look up the definition--pulling unrelated items out of your ass does not further your argument. Face it, you lost, your ego is shattered. hahahaha!!
stingers, MR twin fins, and Astro Deck are not fads. Stingers are still used (and will probably always be) on wider/fishy shapes to pull in the tail, while still keeping a more parallel rail line. I see people still riding MR twin fins around my area (and they all still have stingers). Granted, many of these boards now have a center box for an optional trailer fin, but the rest of the design is still pretty much as MR designed it in the 80s. Astro Deck invented surfboard traction and is still a legit company. Almost every surfer in the world uses a traction pad...how is that a fad?
Here is why it adds strength Barry. Right here you have two pieces of paper that are the same size. If they were glassed they'd take the same amount of resin and would have the same strength in the same size. When you fold the paper you still have the same amount of surface area but now its in a more compact space. Or, more strength in a smaller space. Lastly, this. I won't ask you to wear a helmet but don't be afraid to learn a new trick, old dog.
Actually they do provide structural support just like a corrugated roof. from vulcan benny's boardroom review... "corrugations running the length of the board (the heart of Vulcan’s patented ‘Convex’ technology) are purpose built to store and release energy efficiently. This Convex engineering makes the board feel lively and springy through turns and when pumping down the line"
thanks clemmie I was too busy picking up my shattered ego and putting the pieces in my helmet to post earlier
great demo (impressed you took the time to do all that) the extra strength in an epoxy board probably isn't really necessary. Less function than it is flash, imo, but obviously not useless.
