A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:
Proof of Concept
Explorations that test ideas and functionality.
Demonstrates the functionality of the final product, but looks different.
Looks like the final product, but is not functional.
Appearance and function match the final product, but is made with different manufacturing methods.
Appearance, function, and manufacturing methods match the final product.

The Story Began a Day after My First Stand Up Paddle Boarding Experience
The first idea was to split a SUP board and try to exercise the legs in a similar manner as Snow Skiing cross country. Knowing that paddle boarding only exercise my upper body, I wanted something similar to work out my legs. This test didn't last much because is very hard to control those 2 boards.
The second attempt was to "Walk On Water"
It was easy to think, If I get to big floating shoes with the shape of a boat and having in the back a concave area, I should be able to run on top of the water and scoop the water kinking to the back to push me forward.
After Several Prototypes and several failing test, I realized it was boring to have to swim to the edge of the pool to get back on my floating shoes. Even worst, this device it was already patented. Then after 2 nights of disappointment a new idea came.
The third Idea was to create a water Skateboard.
The Idea was to scoop water with fins located below the Skate Board
The main problem of Water Skateboard was the fact I wanted the board to be very short, this means needed to be very thick in order to have enough buoyancy material. This caused the board to flip and made me fall down either forward or backwards.
After a Failed prototype, I realized it was a bad idea to do Skateboarding on water, due to the leash trapped my foot and flipped upside down with my leg wrapped around the board while I was dawning unlit I manage to release my foot from the leash...bad prototype.
In order to correct the problem of falling down, I connected a perpendicular board wich ended up like a cross symbol. Then connecting both shapes the final look was a stingray, so....
StingRay Shape idea
May be a Stingray was better shape, so the board does not flip upside down
Since the Stingray shape was working very wel, I was feeling like an inventor and decided to purchase a 3D Printer, back in those days was very un affordable... Purchasing a 3D Printer seem to be a good idea. Back in 2013, The cost of the 3D printer was $23,000.0 So I did and ended up eating Cheerios and Corona beer for 3 months due to lack of money
Nice 3D Printed Prototypes
Not very good "WaterBlade Meals"
Then I decided to Motorize it...Woohoo!
Several Motors options were tested and failed. Since I wanted the board to be electric, the main challenges were, the weight of the motor, the speed achieved, the capacity of the battery.
I started with an acid battery, which was very heavy, after several months and several test, I chosen the best option of motor, and lithium battery.
After a few test, I realized I needed more floating material, this is the first prototype choosing where to add more floating material. The wings were the best location to add floating material.
Then I improved the shape of the Stingray, by making smooth transition of the thicker parts.
Improve the esthetics.
All fabrication efforts were done in my living room, making this very difficult, cutting foam inside a living room is not recommended.
Painting in the second bedroom was the only option.
Getting creative with graphics was the next step
Testing and cutting and adding more flat surfaces to be able to scoop more water was one of the options to help moving the board forward
This prototype actually work well but very slow.
Converting the board to Inflatable.
Now what? Id does not fit in a trunk. Start all over and make it Inflatable.
Oh no!!! Testing in a lake rather than the pool, makes me realize, many people will not have a truck to transport, neither will have a storage area to keep it. This was crazy, I needed to start all over again and re invent the wheel. Make it Inflatable.
Seeking Material was the first challange
Finding the right kind of ink was one more challenge.
Finding the way to incude the motor in this type of material.
Is getting closer and closer
Testing final design was a success but could be better always.
KidsRay Model Needed
Now What? We need one for kids or lite people. We learned that smaller kids or lite people was having trouble making turns due to the fact the thick board has too much floating material, so we realized we needed a thinher board for lite people. We need to improve speed and length of the battery life.
The first thing, is to adjust the thickness to allow kids to claim back up to the board.
The second thing to improve was the length of the battery life during a ride.
The last thing improved was the speed, this board has 100Lbs Thrust rather than 62 Lbs from previous version, this obligate me to move up the motor from 12v to 24v.
Several Test have been done very successfully.
Kids Loves it
Really love it.
Enjoy it !!!
Thanks for the Support....
Waterblade baby !
Risks and challenges
The product will look as the picture except the motor will be white and a little faster.
The product will operate as shown in videos. The only Challenge is delivery date if Kickstarter may delay the payment couple of days. But we will make our best effort to match delivery date.
