Hey Og-are those measurements you give right at the nose and tail? (sometimes measurements for boards are taken 12" from nose or tail so I just wanted to clarify)
I like the looks of that board-

Yes, the nose & tail measurements are at the very ends of the board.

Ready for fun.

Hopefully will be able to post up a ride report in the next couple days.

pretty. looks totally store bought. on yours the center looks depressed. on others it looks raised. which is it? outsiders want to know.

It is raised. That look of concavity is just an artifact of photographic depth flattening

I guess the elevated section gives a bit more thickness for flotation allowing thinness in the rails.

If I remember correctly it is more for flex/stiffness modulation in the build.

Both. Here is quote from above in thread that is quote from the designer

"The flex of the board is related to the thickness of the cork, the weight of the fiberglass and how much resin is used. The mechanics of composite design state that when a composite is made twice as thick, it becomes 8 times as stiff. My boards have a center dorsal "bump" on the top of the board - you can see this in all the photos. This bump has a few functions. It makes the board thicker and stiffer in the center. In that way it acts like a stringer, but because it covers a larger area it distributes the stiffness differently than a traditional stringer. (It also creates more float.)"

Geoffrey,

I searched a few other threads, not thinking to search through this one. I'll be interested to hear if there is flex or how/where it flexs.

Sounds like the boards aren't difficult to shape and not toxic, which is a bonus.

On all fronts seems like a pretty genius creation to me. Certainly not for everyone but a "one design" that perhaps beats the ubiquitous bodyboard in a great many aspects

Flojo,

Thanks. Are you saying it flexes if you stand on the beach and bend or in the surf? If the latter, when do you notice it flexing?

Hey Bob, both-if you play around with it you can bend it by hand but it is not weak, it is a nice springy flex. In the water, I have pressed down on the nose while trying to drop into a wave and the flex I was able to generate helps me get into waves. A better rider probably has more examples of use of the flex--

Flojo,

Thanks. Do you notice the flex when riding the wave?

Hey Bob, If you look at OG-Azns initial review of the board at the start of this thread, he mentions flex while riding.

Thanks. I'll see if Og chimes in. Sounds like it was manipulating the nose area. perhaps more - I'll wait to see.

I guess the best comparison on how the board flexes is with a bodyboard. The Bodypo definitely doesn't flex as much as a bodyboard, but the way it flexes is similar. As Flojo said, you can see the flex in the board on land. I've noticed the boards seem to stiffen up a bit in colder (50 degree range) water similar to how polypro bodyboards do. I wonder if they loosen up in warm water like bodyboards. The boards I initially tested were prototypes, and flexed more than current production boards and blanks. I think the production boards were made stiffer as a concession towards durability. The 2 boards I own are made from current production blanks. I've never experienced the boards overflexing or feeling flimsy while surfing hard breaking sandbar waves. The caveat is I haven't had the opportunity to ride them in anything over 8ft face though.

You notice the flex when bottom turning and driving towards the lip. The board flexes and recoils in a positive way in that situation, like a bodyboard. You also notice it in hollow waves were you can flex the board to conform to the wave shape & situation more easily than a typical plywood board. You also notice it on landings were the flex softens the impact. I saw a recent blog or Facebook post were Dave said he's trying to up size the blanks to 48" x 24". That should open up a lot more possibilities with these boards.

That's at OB though and waves there tend to be mas beefy compared to most other surf spots

Hi all - Flojo and Uncle Grumpy, I'm glad the blanks were easy to work with. I've found the same. The material is largely non-toxic, but I still recommend wearing a mask because of the fiberglass dust that'll kick up during shaping. Uncle Grumpy, I'm looking forward to your ride report, I hope you're getting some swell this weekend.

OG-AZN is right — I'm working on providing larger blanks. The new sizes will be great for all of us, myself included, but it'll also be a bit more expensive for all of us, myself included. I haven't figured out exactly how much more, but I like keeping the blank price as low as possible. I'm also working on different shapes for the panel stringer (the raised area), and other experiments.

I see some more questions about the flex. Again, the Bodypo is governed by composite mechanics and the interplay between the cork and the fiberglass. The fiberglass creates strength, the cork (specifically the thickness of the cork) creates stiffness. Strength and stiffness are two separate characteristics here. So if I wanted to make a Bodypo that flexed more, I'd make it thinner with more fiberglass. That would make it less stiff, and the added fiberglass would create the strength needed to flex without breaking. However, nothing comes for free - if you make the board thinner you also makes it less buoyant. The thickness (really, the volume) of the cork dictates the buoyancy. The current dims of the board reflect what I think is the right balance between weight, flex, stiffness, strength, buoyancy and price for this design and materials.
