Surfing Technology

New wetsuit technologies are described in the latest issue of Surfing Magazine. Here’s my favorite.

Quick Dry: What is the number one, non-scientifically proven deterrent from early morning sessions? Sleepiness? Negative! The offshore spray that stings your little eyesies? No, you pussy! The answer is a wet wetsuit. That cold, damp seal skin that seeps into your bones without fear of reprisal. You can curse and cry and call your mama, but you’re still stuck waiting for that sucker to thaw.

Xcel, uses a wetsuit lining that uses thermodynamics to recycle body heat into infrared energy, which in turn heats your body even more. It’s using a constant, sustainable energy source (you) to retain and create further warmth. You are your own self-heating oven! Genius!

What innovations would you like to see in surf gear? (board design, fins, boots, all of it!)

I thought of one this morning in the lineup.....but then changed my mind. A watch that could track the size of sets and time to arrival to your location....changed my mind because without the surprise of the cleanup set the lineup might be even thicker than it is now....at least the bomb set every half hour keeps people "honest" and those who shouldn't be out in the lineup on the beach.

I'm glad you changed your mind. I love surfing because it gets me into nature and away from technology. I suppose it's inevitable that we'll see mounted phones for...

Taking video
Controlling drones
Playing the music list
Shark alerts, and
Reminding us to get out for important appointments.

I watched a little bit of Alana Blanchard surfing live via her waterproof phone operated by her dad. Other than the phone making live video in the water I was reminded of how nice Hanalei is when it's not happening as compared to the beach I surf
So what is worse.... dying or regretting it for the rest of my life? Obviously I chose not regretting it.

That Xcel advertising copy sounded a little bit like hyperbole. But, it made me curious. I re-read my favorite book about thermodynamics and then went looking for information about Celliant (e.g., trademarked name for Xcel's liner). I was curious about the energy conversion to infrared (IR) following conductance (from human body to liner). I was curious to know what reaction produces infrared (IR) energy. Most insulating materials are incapable of doing this because they only trap air or water to contain heat. Celliant's fiber blend includes tiny, tiny, tiny mineral catalysts. The primary minerals include titanium dioxide, silicon dioxide and aluminum oxide. These minerals are spun in polyester fiber. Polyester is normally manufactured from coal, air, water, and petroleum.

The heat-producing region of the IR ranges from 700 to 1100 nm (Malshe et al; Libbra et al). Titanium dioxide-induced IR covers much of this range. Clinical tests demonstrate this energy really does keep humans warmer (conclusion provided in 4 newly published papers). Celliant is used in many clothing applications. The few surfing magzines looked at indicated Xcel's suit made with Celliant really do keep surfers warmer.

My Surf coach used it this year and was really convinced - he buys them himself, so does no advertising. But he also said that after 200 sessions the effect wears off.

On to board technology! Would you consider this for your quiver?

Image

A small company called Trinity Board Sport is making surfboards unlike any other, and enough people are convinced that how they’re doing it will change the industry. The new board is called the Cornice and uses a parabolic rail system and a totally different volume distribution.


Image

According to the company, the parabolic rail makes turning easier by the cutting through the water in the same direction as that in which the fins are turning. This combined turning action reduces the effort needed to make turns and so enables more maneuverable boards without sacrificing stability.


Here it is in action…

The PRS board has 20%-30% more volume than a regular surfboard of the same length–which is good and bad, depending on what you’re looking for in a surfboard. They’ve simply pushed most of the volume from the mid-point forward to the nose.

Performance aside, that is not esthetically pleasing to my untrained eyes!

I wouldn't personally but it but if it was a gift, hell yeah I'd surf it, not sure if the big nose will make duck diving harder though :lol:

The design is from skis and without going into any real thought my first thought is that you don't need to paddle a ski so it probably doesn't translate well to surfing, but I will change my mind if I see some pros using similar boards in contests.

It does kinda have a certain shape to it

Well pros can practically surf anything to be honest, I wouldn't trust a board just because a pro can surf it
After all, this guy surfed a TV! :lol:

Hahaha......ask the lineup what's it like to get dropped in on by a goof on a TV!?!

Good times!

BTW, the engorged board thing seems like they got it all wrong....looking at Tomos and how that bit of the board can be completely taken off, the question I have is why having volume distribution in the nose is a good thing? Seems like it would only increase the swing weight (slowing down the responsiveness of the setup) and would ask for a heavy front foot.

For the pros it's their job. Everyone else just does it for fun. If the pros find it useful that means it is because they think they can win more events with it because it helps them to perform better. Everyone else uses a board because they think they can have more fun with it or some other rationalization.

It was the brainchild of two men, Eduardo Cenzana, who is the lead engineer at a company called Trinity Technologies, and Dan Mann, Firewire’s surfboard designer.


Big H wrote:Why having volume distribution in the nose is a good thing? Seems like it would only increase the swing weight (slowing down the responsiveness of the setup) and would ask for a heavy front foot.


The Cornice features something called a side-cut. Put simply, it’s less foam on the waist of the board, giving it a vaguely hour-glass shape. “The side-cut shifts the majority of the board’s volume from the mid-point towards the ends,” said Cenzana. “In the Cornice outline in particular, [it shifts] towards the tail, leading to a most effective area in contact with the water. The board literally displaces less water, leading to minimal friction and in surfing terms, increased speed that is noticeable.”

With conventional surfboards, at least, more speed equals more difficulty turning. The Cornice may have figured out how to beat that. “Firstly, the water flows more smoothly through the waist of the board rather than buffeting against it,” Cenzana continued. “The way the board fits into the flow of water reduces the water pressure from the wave, allowing the board to respond intuitively to maneuvers. The overall effect is the sensation of traveling on rails, and a feeling that you have complete control over the most radical turns."

Surf culture is reminiscent of high-school, where being weird isn’t always cool, and far too much importance is placed on being cool. But with these new designs, more surfers are opening up to the idea that maybe, just maybe, the board that Kelly Slater rides isn’t all that great for the average surfer. The interesting thing about many of these radical new designs is that, in the end, they makes surfing better easier–something every surfer on earth wants.

Now that you’ve got a Quick Dry suit and a Cornice surfboard, you’ll need some 3D Fins!

As we all know, a golf ball with dimples will fly further than a golf ball without. What most of us don’t know is why? There are two main reasons: The dimpled surface reduces drag; The Dimpled Surface improves lift.

So 3D Fins took those principles and applied them to a surfboard fin. According to the press release, they compared two fins that were identical in dimension, but one had the dimples. They had a guy named Darren Stephens, a fluid dynamics expert, do the testing. Here’s what he found:

A surfboard fin with dimples creates a turbulent flow. Turbulent flow has more adhesion so when you start to turn, the dimpled fin surface delays the flow separation, reducing cavitation (the separation bubble) allowing the foil to maintain performance. When the surfer is turning at high speeds, the turbulent boundary layer helps the flow overcome an adverse pressure gradient and allows the fin to remain attached to the surface longer than it would otherwise. This reduces drag, increases lift and improves overall performance of the fin design.
