Preparing the spread tow carbon fiber

Authors: Flyboy Wakesurf

We are not quite ready to laminate the bottom, we still have some preparation of the spread tow carbon fiber to get done before pulling the vacuum on the wakesurfs. In the last post we documented getting the mylar and new bag ready and in this post we are starting to work with the spread tow carbon fiber itself. As a refresher, spread tow carbon fiber is woven tape, the tape itself is wider and flater and the interlacing is smoother and there are fewer of them over a specified area compared to a normal twill carbon fiber fabric. Further being flatter, theorhetically there is less resin uptake.

This picture shows the spread tow carbon fiber. The weave is really large compared to a normal twill carbon fiber fabric, which offers a number of unique benefits, but one significant issue is cutting the fabric. Being that the tape is large and there are less of the tapes than compared with normal non-spread tow fabrics, the tape tends to unravel and unravel in a LARGE WAY. Leaving a huge mess. The fabric, when cut and shipped is typically taped off, so that it can be removed later and yet doesn’t impact the fabric in anyway when going to do a lamination with it later.

As you can see in the above picture the spread tow carbon fiber has amazing drapability, it curves to all the shapes and fits into the nooks and crannies. It has a great look too, although once laminated it will lose some of that shine. We think there may be some of the holographic effect common with carbon fiber, so we’ll see what it comes out looking like!

In this picture we have run a section of tape along the length of the fabric and we will cut down the middle of that tape along it’s length. In that way, when we cut the tape, half will be in the remaining fabric and half will be on the fabric we will be using for the project.

Now our plan is not to really lap the rails with this fabric, sort of instead rolling over the tuck in the rails but leaving the carbon kevlar exposed over most of the rail material. We’ve noticed when this material is used, mostly the rails are painted. Just so you know, that paint hides all the crappy, jagged unmatched edges. :) We want a clean smooth surface on the rails, so we’ll be basting them with some epoxy and then sanding that area smooth.

Componentized wakesurfs

Authors: Flyboy Wakesurf

Wow! When did it get to be February!

So we are going to finish the construction of our componetized wakesurfs. As you remember it had a hybrid fabric on the top comprised of carbon fiber and kevlar. We had some issues with that lamination, but nothing that will prevent completeing that build and testing the wakesurfs out. You may remember that we discussed the use of a spread tow carbon fiber fabric that we want to use on the bottom. We are really interested to see how that reinforcement works and can visualize some interesting variations on the use of that fabric. For this initial build though, we’ll try and keep the process straight forward, although we do expect some issues with the learning curve!

Now one of the things were are interested in is the very thick weave and we want that to be the predominate theme on the boattom of the wakesurfer. That being said, we need a rather gloss-like finish to best show off the carbon and get that sort of mirrored effect. Epoxy doesn’t gloss up like polyester resin with polishing, so we’re going to try and create it by “molding” the bottom onto a sheet of waxed Mylar.

Mylar is a rather interesting material, it’s a form of polyester, similar to the polyester resin used in old school PuPe surfboard construction. We aren’t using the highly reflective super think sheets that are available, because we are vacuum bagging this down onto the rocker bed and that pressure would tend to wrinkle and crush a super thin Mylar sheet. Instead we are using a somewhat thicker sheet that can withstand the pressure and also be easily waxed. It won’t give us the ultra gloss finished, but should resemble a polished / sanded bottom finish.

In this picture you can see the white’ish colored mylar sheet trimmed to the dimension of our rocker bed. It has yet to be waxed, but when it is it will release from the cured epoxy on the bottom.

wakesurfs Mylar 001

We’ll use slight more epoxy than normal in a lamination so that we can get a good glossy finish, as we might see with a hot and gloss coat added, while also laminating the fabric to the bottom on the wakesurfs.

We will be creating a new vacuum bag for this part of the construction. The last one has reached the end of it’s useful life and we’d rather be safe than sorry in this next step since the carbon fiber material so expensive.

So the first thing we do is cut off a section of the nylon lay flat tube (lft) we use for creating our vacuum bags. It has good elongation, not like the stretchlon, but still good and is somewhat durable allowing us to get several pulls out of a single bag. We use D clamps to secure each end, one remains on the LFT the entire useful life, while the other is opened and close with each cycle.

Next we cut a small hole and insert the vacuum fitting. This has a small barbed hose end the tube leads through to the inside of the bag to allow evacuation from inside the bag.

As you can see, there is also a nut to affix the fitting and a rubber seal inside the bag that acts to seal against vacuum leaks.

wakesurfs mylar 002

Lastly after inserting and tightening the fitting, we loosely attach a small piece of breather cloth so that the fitting doesn’t get contaminated with resin or seal itself against the opposite of the bag prevent a full evacuation. We also don’t smooth out the attached breather, again to prevent sealing during evacuation.

Our next step will be to read the fabric, Mylar sheet and bottom of the wakesurf board for lamination of the spread tow fabric.

Wakesurfer hybrid deck layer

Authors: Flyboy Wakesurf

Ok so while not really a failure, this next step in our wakesurfer build did NOT go well. We were out wakesurfing and videoing James Walker on the slab style board and documenting that build, so we should really refresh everyone’s memory here. We are building a composite sandwich wakesurfer but isolating the components and using materials that are best suited for the specific area of said wakesurfer. So for the top we are using a hybrid carbon and kevlar and for the bottom a spread tow carbon.

Now the process that we like to use for laminating these visible fabric is to lay out a piece of release film, or peel ply that will be used as the carrier. That is when the fabric is wetted out two people pick up the PEEL PLY by it’s ends and carry it over to the wakesurfer and carefully flip it over and place it on the project. At that point it’s fairly easy to align the fabric and make minor adjustments. Well, not the case here. The wet out hybrid fell off of the carrier film in mid flip and well the rest was a disaster!

OK so disaster is rather harsh, but it did create a huge alignment problem. In the future, we’ll most likely to the resin work on the wakesurfer itself after having aligned the fabric and tacked it on with a light coat of spray adhesive. Lesson learned!

Ok so here you can see some of the problem areas that we encountered. First is that we used a wet out table to fully wet the resin and when laying the wet fabric down on the board, we had to stretch it some to get coverage. The end result was those gaping holes as we pulled the weave apart and also the skewed weave, which doesn’t hurt durability, but looks like crap. There also seemed to be a difference in the amount of resin, but we are guessing that is only on penetration. It’s a weird striped look.

wakesurfer deck layer 001

After we lapped the rails, which went really well with this fabric as it’s soft and conformable, we laid out a piece of Stretchlon release film to pull everything tight.

wakesurfer deck layer 002

The Stretchlon was pulled tight and taped underneath the wakesurfer. You can see the weave issues pretty clearly in this photo.

wakesurfer deck layer 003

We wanted to try something new with this board. We applied a layer of breather cloth on top of the wet fabric and Stretchlon. The intent was twofold. First was to prevent print-thru from the vacuum bag, so that wrinkles and stretched parts wouldn’t imprint into the wet epoxy AND to apply an almost traction like texture by causing print-thru from the breather cloth over the entire surface of the board, without impacting clarity of the resin.

James Walker wakesurfing slab style

Authors: Flyboy Wakesurf

We got a chance to take the Supreme V226 out again and do a little wakesurfing, this time, slab style, over the weekend. Now you know that James Walker can wakesurf just about anything, but take a minute and watch the YouTube video at the end where James is pumping and carving this puppy up and down the wake. It’ll give you an idea that length, by itself, isn’t the only attribute to be considered in a wakesurf board. So we are playing a little with the whole slab style name, but we do believe that there are a myriad of options that can be enjoyed behind the boat. Ocean surfing is one of the most stagnant sports on terms of technology of the construction. Literally no other sport remains so stuck in convention, but there are literally thousands of different types of surfcraft. Everething from surf mats to long boards and everything in between. There is almost no variety in equipment in wakesurfing. Skim style boards and surf style boards, it is the most conventional and static environment you can imagine.

We understand that manufacturers will only make what they can sell, but they will certainly make what you ask for! If you are per chance a shaper, c’mon guys you’ve shaped mini-simmons before, break out of that rut and shape something different. Skim boards and surf style boards are all pretty much the same as the next one. When a product becomes a commodity like that the ONLY point of differentiation is price and that doesn’t do anyone any good.

For our testing, we wanted to establish that length isn’t the only factor in shaping a wakesurf board. It’s quite possible to shift some of the length into width. You know that if you are 200 pounds you can’t even look at a 4’2″ long board. Also, if you are less than 5′ long you need a huge amount of rocker to avoid pearling, but none of that is present in this wakesurf board. Also, we wanted to point out that straighter outlines aid with down the line speed. Now we aren’t arguing that straighter outlines are the reason, we understand that they create more surface area, but straighter outlines also create less drag planning along the surface. The rail of one side of the wakesurf board is buried in the wake face and the less there is of that surface in the face, the faster the board will be due to reduced drag. That drag is induced by the amount of rail IN the water via length and also the curvature of the outline which also creates more rail line.

So with that said, lets get on to the wakesurfing pictures with James Walker.

C’mon you know you love the artwork.

Wakesurfing January 002

A 4’2″ is Grom size, maybe even less than grom length, certainly not capable fo 200 pounds.

Ok, so James Walker can wakesurf anything, but finless slabs too?

Liberty with a wakesurf board

Authors: Flyboy Wakesurf

We love this picture of our slab o’ foam wakesurf board for the “Nose with an arrow” placed on the Nose!

Liberty with a wakesurf board

The Slab o’ Foam board is so rectangular that it is hard to distinguish nose from tail and clearly deliniating the direction and purpose, keeps that wakesurf board going straight. You can imagine being out wakesurfing with this slab o’ foam at eye level, it would be hard to differentiation the nose from the tail!

Clarity, then, has some benefits! What were we hoping to establish in this wakesurf board build? One was that Length, the predominant measurement in wakesurf sizing isn’t THE factor. It is A factor, but as we described in the last post a 5 foot long board, 4 inches wide will just suck. It seems to be human nature to simplify to the least number of terms possible, but sometimes that elimiantes meaningful options.

Another thing we want to establish is that those curves on your wakesurf board, slow it down DRAMATICALLY. Straight outlines are faster. We will make a claim here, for a given amount of surface area, a board with a straighter outline will be faster. We’re not sure we can give an accurate percentage relationship, but if the wakesurf board is mostly curved from nose to tail, or nose to widepoint and then curves back towards the tail, it will be slower than a wakesurf board with a less curved outline, or especially one that has mostly a parallel outline.  What we’ll address in a subsequent article is to address the idea of whether the curves are causeing the boards to be slow or if it’s strictly wetted surface area, or perhaps it’s BOTH!

Is a straighter outline the best option? No, of course not. You might love it and it might allow you to slip and slide like Ryan in that video, but it limits the boards ability to carve as easily as a board with a more curved outline. Does that invalidate the concept of short, square’ish and wide? No! There are so many viable options that simply aren’t made available to consumers because the majority speak only of surf and skim and those associated styles or only LENGTH. What do we call this style? Square style? Slide’y style? It doesn’t matter, the point being, don’t allow yourself to be closed to the myriad options that are available to you, simply due to this tyranny of the majority. That majority that doesn’t know or WANT to know that other options exist because change scares them, or would detrimentally affect their control or profits.

Is this Slab style for everyone? No of course not, in fact we’re still not convinced it’ll work worth a darn at all, but to limit yourself to only two types of boards, or only two very limited riding styles not only limits your fun factor, but severely limits any creativity or growth within this sport.

In the infamous words of Patrick Henry: “Is life so dear, or peace so sweet, as to be purchased at the price of chains and slavery? … I know not what course others may take, but as for me, give me liberty, or give me death!” Ok, we’ll close our eyes to the fact that Mr. Henry actually was a slave owner himself, but the concept isn’t without merit, despite the hypocracy!

We don’t claim to be the ONLY facet of innovation within the sport, but we do hope that we can claim to be the most influential. Do you have an idea that seems crazy and far fetched? Try it! You should build it just for the sake of learning and for the progression of the sport. You’ll see a picture in here of the bottom lamination and it’s a face only a mother could love. :) It was posted on Facebook and there were many kind words of inspiration, none more prophetic than from Jimmy Redmond one of the owners of Liquid Force. That’s right! You just thought we were crazy! Anyway, Mr. Redmond commented on the photo “Each new project is an opportunity to progress…” Not IMPROVE within that limit sphere, but progression. Perhaps our artistic abilities are at their maximum potential, but that doesn’t mean that we can’t create something totally unique and progressive within that realm.

Do not allow yourself to be locked into the mainstream of what was, but instead open yourself up to the opportunities that could be.  Progression.

The next time you read hype about biggest, tallest, cleanest wake think instead of what COULD be done with smaller, shorter and “fluffier” wakes. Is there something more fun? Or maybe easier? Let’s open our minds to the endless possibilites and more importantly toss off the shackles of just two board types or the ridiculous assertion that there are only two styles of riding. What will YOU define as progression?

Give me slab style or give me death! Ok, we don’t really feel that way, but we’re bored as hell with the state of the sport, and it’s predictability.  Let’s do something new and exciting and for heavens sake DIFFERENT.

Here is that picture of the nose and arrow. Now we’ll know which way to go! Certainly we all need to be uniform and do the same things. Otherwise there would be anarchy and maybe even FUN!

Liberty with a wakesurf board

In the video, Ryan’s Lord Board was unlaminated. That foam was also a little higher density than we had available so we tossed on some 6 oz glass. Here we are sizing it up.

Liberty with a wakesurf board

Every new project is an opportunity to progress. Lord knows it needs something! :) There is a theme in there, can you decipher what we were trying to convey?

Liberty with a wakesurf board

We actually kind of like this one, each color contributes to the overall appearance, not attempting to overshadow, control or block out the others.

Liberty with a wakesurf board

So the whole slab style board has been laminated and we’re just waiting for an opportunity to take it out and do some sliding around. We hope it works somewhat like how Ryan used it. We won’t have the size, power or length of wake to generate the speed that Ryan did, but perhaps we can still generate the level of FUN! We hope you’ll spend some time thinking of alternatives to the stifling status quo, too.

Tyranny by the majority in wakesurfing

Authors: Flyboy Wakesurf

Have you ever read a post on a wake related site where folks suggest that length is the only factor that you need to consider if your wakesurf board isn’t wakesurfing well for you? It’s so prevelant as to be ubiquitous. So what about width, thickness or rocker? You NEVER read about that do you? You know why? The majority of folks, while well intentioned, have no idea what they are talking about with regard to wakesurf board design or what works. Instead, they like being part of the discussion and presume they are being helpful so toss out the single most discernable feature, length. Go longer or go shorter as if wakesurfing was a single dimension. Also there are many that have agendas for control or selling wakesurf boards that hide behind anonymous screen names offering that LENGTH or a specific style of board is the best or only consideration.

So, how is it possible in a three dimensional world that only one dimension could be the single most important factor? There is a presumption that the UNREPRESENTED components are going to somehow magically be adjusted. So if you are riding a 4 foot board and someone says: “go to 5 feet in length” that the rocker, width and thickness attributes will be considered. Is that likely? No, more often than not the other dimensions remain static, or are changed in the same ratio as the first wakesurf board. Does that work? No, since there is no real thought given to the other dimensions and there is no representation, the minority measurements are after thoughts. Remember way back when we adjusted the apex of the Flyboy Wakesurf board? The location of the apex of most wakesurf boards, before we made that change, were simply a scaling of ocean surfboards down to lengths appropriate for wakesurfing. So those shapers took a 6’2″ shortboard and shrank all of it down to 4’10″. What happened to the apex? It got moved backwards.  Did your stance change? When the surfboard was “shrunk” did the rider shrink too? Nope! The “take away” from that is that if the design of that wakesurfing system rests solely on the majorities presumptiveness, there is no representation for the various minority interests and you end up with CRAP.  If every single board was 5’6″ in length and 23 inches in width what do you think your riding would look like? For some it would be perfect, because that sizing would be just right, what about if you are 5 feet tall and weight 95 pounds? That would be a LOT of board!  There is still so much misinformation and under-representation that it makes it hard for folks to understand that they have options.

Do you know what the aspect ratio is of your wakesurf board? We are willing to bet that 99.99% of you don’t. We’d be willing to bet that the vast majority of folks don’t know what the width of their favorite wakesurf board is either. Know what length it is? Interestingly enough, we think the vast majority of folks do. So therefore the only important measurement is LENGTH! We know, logically that isn’t true, lets take an over exaggerated example. You ride a 5′ long board and you’re not quite sure of the width, so we could change the width to 4 inches with your toes dangling off the edge into the water and it would be perfect and ride the same! Really? :) No, of course not. Width, within a relative range is very significant and will impact the ride quality immensely. Want to know something else? If we assume that wetted surface area is a significant contribution to a boards planing ability, then length adjustments are the least significant contributor. It’s true!

In simple terms, looking at a rectangle of 5 feet by 2 feet, adding 1 inch to the length adds just 24 square inches of area. What if you add 1 inch to the width? 60 square inches. Two and a half times more! What’s the quickest and easiest way to add wetted surface area? Width! Yet, it’s virtually never discussed when it comes to attempting to adjusting a wakesurf board to fit a rider. Well, let us take that back. The majority has deemed that length is the only important factor, excluding any minority view. Now a good shaper will adjust the width and length to properly fit a rider and the wake they surf on, but of course they, like you folks that are reading this, understand that focusing on a single factor or interest, without properly considering the other factors that influence the way the board wakesurfs and at times, the majority grabs on to an attribute that often has much less effectiveness in deteriming how to improve a wakesurf boards performance.

So are you going to consider all of the factors in your next wakesurf board purchase, or just length? Are you going to contribute to the tyranny or try and find a board that is better suited to your particular situation? No more length discussions! :)   In fact we are going to make every effort to dispell the notion that length is the most significant factor to consider.  This “wakesurf board” will be 50 inches in length, that’s a 4’2″ board.  What would the tribal knowldge conclude? At 4’2″ it will not go fast, it will pearl, it will not stay with the boat, it won’t “float” a 200 pounder and any number of negative connotations.  Do you buy into that?  NO!  You read the Flyboy Wakesurf site, so you understand how much crap floats around out there.  Well, unless all of that is true! :)

Ok, so that isn’t quite as popular as the 99% and occupy movements, is it? But it’s easy to see how such movements gain traction when collectively, the focus is on a single interest or attribute.

We want to revisit the Lord book on planing hulls. In his testing he worked with aspect ratios – length vs width. There is that LENGTH thing again! In Lords testing he left length relatively static and increased width, noting the change in characteristics of the planing hulls performance based upon changes in this aspect ratio. In short, and you can see a copy of the pages below, an aspect ratio of 40% was one of the best for handling rough water and also developing lift, etc. That at ratios higher than 40% the various performance metric started to fall off, with the exception of wake development and sort of a smooth flow of water. Ratios of 50 and 60 showed marked improvement in these areas. You can read the conclusions and reference the photos below.

wakesurfing

Wow! So we’ll skip those. :) I know, you want to glide over the surface of the water like a water bug. Or do you? The one issue that we take with modern wakesurfing is that it refuses to recognize that there are so many options available to us, instead herding us into two catergories. Surf and skim. This slab o’ foam glides along like a planing hull, sliding and spinning. It’s doesn’t clearly fall within either category, so this sort of thing gets relegated to no man’s land.

We are going to use the aspect ratio of 40% which is the same ratio that Ryan used with the board in the video. It’s mostly rectangular which isn’t the best choice, but if we can slide and spin like that, who cares!

So we dug out a LARGE section of some 2 pound EPS foam, we have already used a section. We wanted to mess with you and say, ok, here it is we are going to surf THIS! :)

wakesurfing 001

So we started by hacking off the one section to make it easier to cut and then marked our dimensions of 50 inches by 20 inches which is an aspect ratio of 40%. You can just see the lines drawn on the foam.

wakesurfing 002

Now for the outline! Graceful curves. Ok, not much of them, the end at the nose if 16″ wide, the end at the tail is 18″ wide and the wide point is 20″

wakesurfing 003

So what would you think these dimensions would produce? Sort of a slug, right? It would go straight and not turn, but you saw the video, that thing did turn but it also offered up a differeing style of riding, one that was mostly sort of floating and slide’y and spin’y. Oh wait, we only have 2 pegs available to us, is it surf or skim? It’s such a detrement to the creativity of the sport to have such huge blinders.

Oh my, did we over shape the rails? They look kinda thin at 4 inches and boxy.

wakesurfing 004

Nicely drawn rocker. Did we ask you opinion on the drawing skills? Huh? Did we? :)

wakesurfing 005

All finished shaping, it took the better part of an hour including dragging the foam out.

Isn’t it gorgeous? Oh you know you want one! We are going to laminate this one with some 6 oz fiberglass. So we hope you’ll tune in tomorrow as we start the process of lamination and remember, no more length only discussions/considerations!

Wakesurf board and server errors

Authors: Flyboy Wakesurf

Wow! What a morning we’ve had. The server that hosts the Flyboy Wakesurf Boards website, flyboywakesurf.com went down and it tooks HOURS on the phone with the hosting company to get that resolved. At least we are back up and running! However that does put us substantially behind in documenting our current wakesurf board build.

Being so far behind, today’s post will be quick and sort of out of sequence with what’s going on! Hopefully we will be back up to speed tomorrow.

One quick picture of the Carbon and Kevlar Hybrid fabric that we will be using to laminate the deck of our wakesurf board. The fabric has not been laminated in this photo, merely cut to basic shape. Hopefully we’ll get to laminating it in short order.  Is that some Red or what?  It didn’t look so overwhelmingly red on the roll!

We apologize for the delay in documenting the two builds underway and appreciate your understanding!

Wakesurf boards aspect ratio

Authors: Flyboy Wakesurf

Over the years we’ve been critical of wakesurf boards that don’t have tow-in or cant of the fins. Then doing some research we tripped across a Tomo Surfboard. We were fortunate to have seen several of this brands boards at Sacred Craft here in Northern California in Santa Cruz. The Tomo surfboards are unique in that they basically have straight outlines and rather wide tails. The Flyboy Wakesurf boards were design from the onset with straight outlines, because they have proven to be faster down the line.  At least one of those boards has no tow-in, the offest is zero degrees.  That got us thinking about wakesurf boards and their design.  We tend to be students first and designers second.  We thoroughly enjoy understanding the principles put into effect in designs used by others. 

Way back in the day, Lyndsey Lord a naval architetch wrote and published a book on Planing Hulls. As the story goes, back in the days of Prohibition, he was funded by wealthy clients (mafia) to develop fast planing hulls that could run rum to the US and outrun US law enforcement. It’s a fun story, even if it’s more myth than not. In his book, one of his theories is that straight’ish parallel outlines were faster and created less drag. We’ve certainly felt that was an accurate theory, maybe the rum runners did too? In handling the Tomo surfboards at Sacred Craft, those surfboards also had very straight parallel outlines, with wider tails which supported the straighter outline.

Here is the cover of that book.

Wakesurf boards aspect ratio

To further our history lesson, you may have heard of a mini-simmons surfboard. An early pioneer in surfboard design, Bob Simmons developed a number of surfboards that used some of the formulas presented in the Lord book on Planing Hulls. Simmons’ surfboards had very straight outlines, wide tails and low rocker. They were fast boards and a deviation from what was popular at that time. The mini-simmons variety, sometimes called “bars of soap” are shortened lengths. Typical measurements would be 5’6″ and 22″ wide. In the Lord book, he defined aspect ratios that seemed to work best in ocean settings, with the best ratio being 40% or 0.4. That is, the width of the craft was .4 of the length.  He documented that higher aspect ratios, in the 50% and 60% range created smoother “release” and less trailing wakes.

Here is a visual of a Mini-Simmons. Note the relatively straight outline, twin keel fins and a sort of bump towards the tail where it is pulled in.

Wakesurf boards aspect ratio

Jump forward almost 50 years and a young shaper by the name of Ryan Burch took it upon himself to unravel some of the mystery associated with the early Lord and Simmons formulas. He crafted what is referred to as the “Lord Board”, which translated much of what the architetch and surfboard shaper therorized. Straigt’ish outline, low rocker and an aspect ratio that is around 40% What was more interesting is that this is just a hunk of unlaminated closed cell foam. No fiberglass or resin, just foam. Below is a picture of that Lord Board. Look closely at the profile view, do you see the nose rocker? It’s just a thinned bottom!

wakesurf board aspect 004

Doesn’t it just look like a slab of foam? Probably because it is! You can see there is a very shallow rocker and it is mostly a very straight outline, with exceptionally wide tail. Did you get a good look at the tail channels? :)

Ok, Ok, Ok, the proof is in the pudding, as they say. Wanna see how Ryan surfs that slab o’ foam? here you go, his video:

How does your wakesurfing compare? Do you have those surface reverses down like that? His style encompasses such creativity, it embraces a skatey-style that is fluid and slides around on the wave. What would you give to be able to ride and slide like that?  It got us thinking that we’d like to explore the design elements encompassed by Lord and Simmons.  In particular the 40%’ish aspect ratio and the super wide nose and tail.  There isn’t much carving going on, but that doesn’t invalidate the style, it’s just different.  Love it or hate it, we think you’d like to be able to wakesurf like Ryan surfs that slab o’ foam.

We have a chunk of 2 pound EPS foam and we want to try shaping that Lord Board with an Aspect Ratio of around 40%. Think we can ride it behind the board? All finless and the like?  Think we can slide it like that on our Supreme V226′s wake?  It has a wonderful transition, but we may have to tone it down some.  This is something we love, being able to create a wake a wake surf a design that isn’t currently done and mastering a new style of riding.  Fortunately we are narrow minded and locked into just one style or type of riding and can explore the myriad options.

Wish us luck and we hope you’ll follow along, because this is something that anyone with a local Home Depot can make!
