The IAQUA Story

We were the first authorized SEABOB dealer, that was affected on our market by IAQUA!

Since 2013 we are exhibiting at international boat-shows in Thailand. 2016 we were invited to the VIP KATA Rocks Boats how in Phuket in order to show off our main product SEABOB. Well, we were stunned when we witnessed the debut of a IAQUA. Back then it was still a dummy and a bunch of international enthusiasts. We already felt and figured that this team of smart young men had the mission to compete with an improved dive scooter at much lower price.

Only few months later at the Thailand Yacht Show IAQUA showed off again several dummies, but also a working unit. Our sales stalled at this boat show and we knew that next Thai season it would not make sense to present our prime product in Thailand anymore.

2018/19 we were invited to the official presentation of IAQUA at famos CATCH Beach Club. We had the chance to test STINGRAY ONE & NEO. Numerous international dealers were present and surprised of the professional way the new product was presented to the public.

I Aqua is a big high tech player in Shenzhen China. The background is impressive, because IAQUA is a branch of one of the biggest automotive parts manufacturers in the world. This means that IAQUA products follow high automotive quality standards!

IAQUA produces genuine industrial products. This is why quality is high and costs are low. Also the innovation and production speed follow car industry bench marks.

Maybe now you understand why IAQUA will be a game changer and with STINGRAY they just started to revolutionize water sport products.

The IAQUA team consists of international engineers that are proud to work and produce in high tech Shenzhen. Product development and innovation take place where highest technology standards are given. We all must understand that in many aspects this is not any more only the western world! Where does your phone come from? Who builds the best TV's , Where do car makers purchase technology?

Dive Scooter History

The stingray is the prime IAQUA product. It took around two years of development to create a state of the art multi-functional electric water craft. In dive scooter history there have been many types of scooters. What pops into mind are torpedo like shaped machines that were used in James Bond movies in the 1970's.

Those scooters were already battery driven, had a propeller/jet drive, handles and some sort of switches and indicators to turn on/off and adjust speed. Also on top of the water / for snorkeling there was a very common gasoline driven snorkel scouter in the 1980's. Many clients report that they actually used that water sled when they were young.

Dive industry produced numerous electric driven scooters that had improved hydrodynamic efficiency, small size, exchangeable batteries,  and even good looking colorful design in mind (SCUBAPRO, SEADOO and many more). A device called "Delph Jet" represented a very powerful version of such a dive scooter and contained modern and crazy expensive space technology Lithium Ion batteries. Unfortunately the company had no success and stopped business.  SEABOB redesigned the Delph Jet and gave it another name (SEABOB), some color and better marketing.

SEABOB was in approx.2007 the latest upgrade in dive scooter industry. SEADOO and YAMAHA also redesigned their scooters and switched to LI-ION technology. The SEABOB 5.12 was very heavy but very fast too. SEABOB Rave Jet, ACS, VX2, 4.12 and F7 where all simply variations of the original SEABOB 5.12. Some models had more power or exchangeable batteries (actually nobody used this feature much).

CAYAGO (the SEABOB company) managed to reduce weight further by switching to the industrial standard "18650" battery cell type. The hull is modern plastic design, similar to seadoo jet skies. There are few aluminum frame parts. The so called "F5" series is up to this day the only product of CAYAGO. F5S and F5SR are derivations of the F5 that contain more batteries, hence more power and capacity. With introduction of the SEABOB F5SR the integrated camera was also presented.

SEABOB F5/F5S/F5SR share the same base construction. SEABOB was very successful with this product, because it was simply fun and much lighter than the former F7. However, constant technical draw backs were also part of the new F5 series history, and it is not an easy task to provide service all over the world. Main problem was that a SEABOB could not be entirely diagnosed/repaired off shore.

IAQUA redesigned the technology up to date and made a dive scooter not only even better, state of the Art technology, but also a lot less expensive. Genuine industrial production is the reason for not only improved technology but also reasonable prices.

Water sport industry is changing, and we believe that all kind of water toys will be revolutionized and will benefit in modern technology and advantages of industrialized production.

IAQUA general Information

The STINGRAY from IAQUA is a dive scooter that can be used on top and under water, down to 40 m. It is battery (accumulator) driven and can be recharged with a fast charger. The STINGRAY weights approx. 36 KG, has a modern marine grade aluminum and plastic design, but is also available in a much stiffer full carbon version. The STINGRAY is build with simplicity and innovation in mind. All modules are mounted neatly on a tray/platform. Crucial parts (like the handles to hold on and the carry handles) are metal supported (marine grade aluminum). Also in terms of thermal design no compromises were made.

The ECU (the brain and power switching center) is milled aluminum and will transport heat very effectively into the air or water. Many dive scooters, electric surf boards, and other electric powered machines suffer severely from thermal problems! This causes the devices to cut down power, stop, or even get damaged. MOSFETS are the most sensitive parts of any modern electric driven vehicle. They will transfer battery power into motion, by supplying a precisely triggered frequency controlled high current to the electric motor windings. This high power switching technology is a critical process to manage and control! Most manufacturers rely on radio shack parts or have them customized. IAQUA develops critical parts from scratch, applying latest technologies and up to date components.   

MOSFETS need to be cooled down constantly or they will simply burn. It is essential that a manufacturer is able to control thermal dynamics and constructs a technology that safely enables and controls high currents and excessive heat development. It takes the best available parts and most up to date technology in order to compete in that segment. Constant technology revision and improvement is the only way to stay on top of performance, reliability, and also product safety.

IAQUA not only has the resources and access to the highest technology standards, they also have the engineers that understand how modern technology works and can be applied in an industrial sense. This is what makes the STINGRAY unique on the market, because it is the high tech industry discovering the water sport market!

Many "garage manufacturers" in the dive scooter and electric surf board market will suffer from this development. However, the users will profit in high quality, innovative, state of the art technology, and affordable products.

It is our job to confirm that those products meed our standards. They do! That is why we distribute IAQUA and forwarded the Manufacturer also our high standards and expectations in efficient and sustainable service and distribution philosophy

STINGRAY facts & pricing

STINGRAY is the name of the dive scooter / water sled from IAUQA.

The product variations are: ONE, NEO, NEO+, and EON

All off the variations share the same dimensions, approx. weight, packing and chargers.

This means you can use a STINGRAY ONE fast charger also for the EON, which is quiet unique in this segment. IAQUA is at least within its model range applying only one type of charger!

What differentiates the model variations besides price?

First of all you have to understand that IAQUA is not down- or upgrading its models in battery size (number of cells)!

Specifications differ a lot between the models in terms of trust and speed. Only a lithium cell can provide the amount of current needed for top propulsion and top speed.

Naturally the ONE contains different battery type than the NEO. ONE contains LG standard high power cells, that have a good overall performance and life time.

NEO, NEO+, and EON contain SAMSUNG high power cells, that have a great overall performance, a higher capacity than LG ,and are capable of providing very high current rates without overheating or suffering in life time. That is why of course the price of a ONE is different to the price of the other models!

It is a bit like with cars. The same model comes with different engine options! A V8 is of course different in performance and price compared to a V4 engine. If power is produced by "tuning" an engine with turbo charger and higher revolutions, it will downgrade live time and increase service costs!

STINGRAY ONE is affordable and a lot of fun! IAQUA dedicated great specs for the the ONE in order to be on eyesight of the competitors mid range model already. IAQUA does not offer a model that weights less, because it only contains half of the battery cells!

You already receive full specs with a STINGRAY ONE at an attractive price tag! Only down side is that the ONE comes only in two basic colors, add-ons are preserved for NEO, and the peak specs (speed/power/capacity) are limited due to above explained difference in battery type. 

The STINGRAY NEO is a very basic equipped model (no add-ons), but it is equipped with the high power SAMSUNG cells and provides full specs!

IAQUA only offers two models: the ONE (explained above) and the NEO! The NEO is already the most powerful and fastest scooter in the world!

The STINGRAY NEO+ is the model that we import mainly for Europe, because it comes with a very attractive add on Kit and does not cost much more than a NEO.

The most striking and very important NEO + feature are the high power integrated LED sub Lights. You can turn them on and off. With lights you can be seen by others, even during day light! Just like it is obligatory for motorcycles we strongly recommend to switch on lights and increase safety!

The SUB LIGHTS are very powerful and enable you to simply use a NEO+ in pitch dark and light up the ocean! We did test dives i Thailand and it was stunning to light up night life and even more feel like a space ship in 0 gravity ... an unforgettable feeling. With sub lights you double up fun time, because now you can explore oceans also at night! This can be also very interesting for rental stations since at night usually beach business stops ... well not anymore!

The CARBON KIT will increase appearance a big deal! Think about sport and luxury cars and how carbon is not only cutting down weight and improving stiffness, it simply looks incredibly cool! NEO + has a carbon display housing and the jet outlet bezel is also carbon.

When IAQUA is applying carbon its real carbon! Other brands apply vinyl wrap,dip in wrap, and even apply real carbon fiber on top of the original plastic body! Well, there is only one real way to apply carbon. The part is a carbon part with carbon benefits like increasement in stiffness and less weight. Only then it is real carbon and will create the stunning look!

SPECIAL COLORS are another striking difference in appearance. IAQUA provides within the + package a free choice of colors. This includes colors only reserved for NEO + (Corsica Orange and Bahamas Blue), and also metallic colors at no extra costs! We mainly import for you of course the metallic colors, as they improve the appearance in combination with the carbon kit and also contain a better color quality (more layers of paint).

The SHARK GUARD is also on board and is a truly unique feature. Turned on, it supposed to hold off sharks by creating an electric field / like an artificial cage. However, we can not guarantee that sharks will back off and we recommend not to use one of our products in areas where sharks are at hand. If you encounter a shark and if that shark is unfriendly (normally you never see one and if, then they usually back off/don't care), then this feature may be your last resort and may save your life!

The STINGRAY EON is packet with all above features and the key difference is that its complete hull (upper and lower body) is from genuine carbon fiber! Naturally the EON will be the winner in appearance and if you own one then you can call that not only the fastest and most advanced water toy in the world, it is also the most impressive full carbon high tech weapon that increases stiffness and speed up even more.

The properties of a full carbon STINGRAY are better because less weight means more speed! Also the stiff body improves agility and planing even more. Is there anything that can be compared to a EON ? Well, the competitive product with similar specs is also available in carbon, but it is simply carbon laminated on top of the upper plastic hull. The EON is a true CARBON construction and also the lower hull benefits from the stiffness of the CARBON fiber and therefor decreases drag and deformation. 

We hope that you now understand that the model variations with IAQUA really mean big differences and not only artificial variation of a core product.

Especially for rental business, commercial use, and just to be sure to cover also heavy weight users, we recommend the NEO+ or EON!

Sub Lights are a big plus and the striking look underlines your investment in a power- / beautiful machine.

With a NEO+ we think you purchase the best "bang for your buck", including highest quality components and a striking sporty luxury sport car look at a reasonable price tag.

We have mainly NEO+ in stock. However, you are welcome to order with us any IAQUA product STINGRAY ONE is the biggest bang for you b



Since our products have been confiscated by POLICE in Spain, because a CAYAGO lawyer insisted that IAQUA is suposed to be a SEABOB "copy",

we want to contribute with our opinion in this matter!

First of all one must understand, that DESIGN right is a comlecated matter. The regular user/ ordinary observer  shall not mix up Design rights with simply 1:1 copiing a product!

Here are the reasons, why an IAQUA can never be a SEABOB copy:

  • an IAQUA SINGRAY is called IAQUA STINGRAY and not SEABOB! This is clearly marked on the product and advertised that way!
  • an IAQUA STINGRAY is not a 1:1 copy and it would be stupit to advertise, sale a 1:1 copy in stores and on internatinal Boatshows in EU!
  • an IAQUA STINGRAY is a bit bigger and a bit higher than a SEABOB, so it cant be the same!
  • IAQUA contures are straight and sqare instead of curved and round elements on SEABOB. Thats a clearly different design language!
  • IAQIUA contains a different technology and therefore also the design is different! You can not remove the top deck, because IAQUA is simply openend up at the bottom and then you have the insides presented on a tray! On a SEABOB the top cover must be removed (I AQUA does not have that!) , in order to loosen upper screws that hold the inside parts together. If the bottom is then removed the inside can then be removed, like removing a spine with attached organes from a dead fish. 
  • IAQUA has LED lights! The design also reflects this fact! SEABOB does not have lights!
  • If you look at the back of an IAQUA, then you see a big visual difference between a SEABOB and an IAQUA! The back is the part that is not  affected by hydrodynamic design, besides the JET OUTLET. Hydrodynamics is why an IAQUA, and all scooter designs like the 2002 DELFJET and 2008 F7  look similar! Water is 1000 times denser than air! A fast dive scooter must simply be shaped / look like a dolphin in order to be hydrodynamically efficient! IAQUA and SEABOB are both hydrodynamic efficient designs. However, each one is unique and clearly different! It is not possible to claim rights on a general hydrodynamic design! A think must fulfill a fiction, and that can not be protected by design! If a t all then only the very unique part of it!

Let us now slip into a so called "skilled user" view point. Acording to design laws world wide, the skilled user is a person that is aware of a specific product, because he is skilled in recognising, working, using, buying, and repairing a familiar product. This can be a water sport sales man or a private person that does water sports. It is important in design right justice that a skilled must be able to tell a product apart from a possible copy. In reality if a skilled user is clearly aware that the competitor is not the same, then it is not a copy and also not abusing another products design rights!

For example, Jet Skies are very hard to tell appart for "unskilled users". An unskilled user that spots a Jet Ski has now way of telling appart a SEADOO from A YAMAHA or KAWASAKI Jet Ski. There are only three relevant brands today, but they can not be separated easily. The design dencity on Jet Skis is not very high (only three brands), and still they almost look alike!

The reason for that is that form follows function! You have to sit on a Jet Ski, hold the handle bars and with a hydrodynamic shape of a small boat you end up sitting on the same thing ... no matter what the brand name may be.

A skilled user can tell a Jet Ski from far away only apart by soptting the cooling water beam of a YAMAHA. Or the typical aggressive green colour scheem of KAWASAKI. SEADOO Jet Skies look very impressive the closer they come. However, it is very hard to tell them apart and also the technology is the same in all Jet Skies in any case. Nobody on earth would confiscate a KAWASAKI Jet Ski, because it looks similar to an YAMAHA!

Looking at an IAQUA as a skilled user, I can spot immedeately the different, more clear outline. I can see the massive rectangular display. And the overall more masculine look! A SEABOB is curved and round. It looks like sucked up candy that with washed away hard lines. 2010 - 2015 BMW had a similar convex and concarve design. Its a desing language from 2012! IAQUA is 2018 massive and mascular / clear lines design language! SEABOB display is round and it is smaller! Also SEABOB loves to apply chrome on their exterrior. Finaly the brand name is on the side and clearly carries the information that it is a SEABOB or an IAQUA!  An Iaqua does not fit into a SEABOB bag! It does not fit into a SEABOB rack!  

Please understand that design law lawyers and courts can detail that issue down to elements where ordinary users never ever be aware about.

Still, it is important to protect unique design! However, at the same time one must credit a company that has imporved a product that had a 10 year history and freedom of competiiton. It was clearly not the design and the technical patents that were the reason for SEABOB beiing relatively lonly on the market. It is the acceptence of the clients and in the end the influrencing factor that so many people around the world contributed! We were the fist to rent & event SEABOB! For us it made no difference waht the product name is or how it is shaped. It was simply a dive scooter with state of the art technology inside! Same as many aother rather boring devices experienced a technology boost! Look at street scooters, phones, TV, electric bikes and so on! They al improoved and are suddenly a lot more fun. It is the user that makes a product great not the design! Nobody purchased a SEABOB because it looks good in the restourant or at a party! SEABOB is a high power dive scooter ... nothing more and nothing less! And now there is another high power dive scooter with better properties and updated technology and 2018 desing language. There is not much room for a different design. Look at mobile phones ... who stands out! The user demands a specific design that has a functionality! Better function is better / different design! IAQUA has a rectangular and bigger display! Thats a difference were a difference is possible! IAQUA could not shape the STINGRAY like a brick ... it would not be efficient in the water!

It is simple to understand design protection law if you look back on PRE-EXSISTING DESIGNs (pior art) and know what to compare to!


This is the DELFJET. It was invented between 1995 and 2002. It was offered randomly and in the end sold to investors of DELF Sport GmbH.

It was also available for a short time at GERMAN radio shack "CONRAD".

Here are some interisting documents about the product DELFJET the true SEABOB history.

According to information from DELFJET founders the product was good and business picked up. Suddenly there was a need for more investment.

This was the moment when the CAYAGO founder Mr. Peter Walpurgis came along and purchased DELFJET rights and patents. If the former company went bankruped or simply stopped is not clear, however, lots of DELFJET founders were left with lotrs of questions and lost actualy their invetment!

However, the design was then already revealed and form that moment on part the DELFJET / SEABOB F7 are prior art!

A pre existing design of course influrences the design language from that point on. That is why it is called prior art.!. 

The way a modern dive scooter is creating a impression on the user  is influrenced by desing evolution ( prior art)!

We want to give you an insight on this evolution and sharesome  facts about design rights.

It is not true that a registrated design automaticaly overrules already existing design (prior art), even if the rights are held by the same company/person!

First of all a design must be new and unique. If it is not new then it still will be a registrated design but it is simply worthless because it can be deleted if anybody can proove that it was not new! Design right registration does not  involve any check on prior art by the reistration office! Any design will be allowed.

A SEABOB F5 may be an unique, however, an IAUQA is also unique and has a registrated design. Both of them have the same design roots! This is what we want to proove to you now:

"DELFJET" 2002, (picture from INTERNET) This is the original design of all modern scooters that followed. Does it remind you on an SEBOB? If it does then SEABOB registrated design can not be "unique" and is in fact worthless design right.


(picture from CAYAGO sales adverting material from internet)

This is the basic design of the follwing SEABOB models: Ravejet, 5.12, 5.12 ACS, 4.12, F7.

CAYAGO gave it many names and many colours. This is the old SEABOB design. It was revealed around 2007 up to approx. 2014).

Oh, did you notice the simiarity? Does it remind on the DELFJET?

Well, all that CAYAGO (former Rotinor GmbH) in our opinion did, was giving the purchased DELFJET a face lift and named it SEABOB! The rest was marketing. and to an we (www.seabobbase.com / TOYMASTER TIMELINE) were part of the marketing and actually made SEABOB famous!

First SEABOB rental base, first SEABOB scuba dive, first SEABOB try&buy, first SEABOB repair was our success! Many other SEABOB friends followed.

So lets get this understood in detail. 

DELFJET is the Granddady of SEABOB design and lets say this "granddaddy married CAYAGO. Together they had a chiled that looked a lot like the granddaddy (Delfjet) and they named it SEABOB (second name Ravejet, ACS,VX2, F7)


Lets see what the children of DELFjet and SEABOB  look like:




 Do baby girl SEABOB and baby boy IAQUA look alike? Yes they do, because they are both children of the F7 / Delfjet genoration!

Are they twinns! No they are not!

Lets see waht they look like with "their pants down":


wow, is that not a big difference???

You can clearly tell boy and girl apart or not? CAYAGO SEABOB compared to IAQUA STINGRAY  from behind.

SEABOB girl is ab bit older than SEABOB boy. That is why she looks and styles a bit older too.


This above design evolution example is how desing law is handeled by the law!

In the end it is the ordinary observer / skilled user that needs to be able to tell the difference. If "family and friends" can tell the "children" SEABOB and STINGRAY appart, then all is ok!

So waht is the problem?

Well, in design right fights the main goal is to stop the bussines of the competitor by all means! In our case CAYAGO stopped sales of IAQUA STINGRAY at Monaco boatshow 2018 and PALMA Boatshow 2019. How did they do it?

Well for Monaco Boatshow the CAYAGO lawyers simply sent a letter to the boat show director and accused IAQUA on infringing rights. In other words they wrote a simple letter accusing IAQUA of somthing that is not actualy proven to be correct! Since IAQUA was at the show as a guest on a friends stand, thy simply respected the friend and resinged from the show. CAYAGO has a stand on Monaco show and of course the show director had intrest to protect his good client as well.

At PALMA international boat show the storry was quet different! We were presenting legaly imported IAQUA Stingrays on our stand as exihibitor! Since 6 years we are exhibiting at PALMA internationa boat show. We also warned the boat show director about CAYAGO! We had a letter in place that stated that CAYAGO will try to accuse us of selling something illegal. Exactely one day before the show CAYAGO used the same "trick" as in Monaco and sent a letter to the show. THe show director was not impressed and did not kick us off the show like the Monaco show officials did to IAQUA!

CAYAGO was prepared and had a spanish lawyer in place that simply PERSUADED the police to confiscate our goods WITHOUT any legal judge decission in place, cusing a 45.000€ damage to us! Yes, this is true! download the entrire consfiscation statement of facts report here!

How do lawyers persuade police and in the end judges? Well it is simple! They compare pictures of baby gurl and boy CAYAGO SEABOB / IAQUA STINGRAY! They use of course not a picture where you clealry see the deifferences (compare above pictures with SEABOB and STINGRAY side by side viewed from behind), they use a a picture were both are showen in an angle that does not point out differeces. Like comparing photos of people from far away / showing only their outline.

  They do look alike, why?


First of all the above picture comparison is the point of view where both products look alike as much as possible! On top of that CAYAGO lawyers obviousely used some photoshop tricks to create an illusion. A police officer that never in his live saw a real SEABOB or IAQUA can not possibly judge that IAQUA is a copy of SEABOB, based on the above comparrison alone! 

This is how they tricked around in our opinion:

You can clearly sea how the most matching viewpoint of the design is usedto suggest a similarity!

On top of that the SEABOB has a "light reflection" contour line that in reality does not exist!!

This in our opinion a cheap attempt to make the SEABOB look actualy look more alike an IAQUA!

And to emphasize that impression the IAQUA logo has been erased to an extend where a plice or judge can not sport it!

Those are original pictures from the CAYAGO Lawyer accusation letters that were sent to the boatshow and police, in order to accuse us to simply sell fake goods ... as if we were selling fake RAYBANS!

We have evidence that proof eveen more clearly that CAYAGO or CAYAGO lawyers (MLL in switzerland) have actualy faked images in order to presuaide official boddies to belive them and take action! We are wondering how it is possible in EU to actualy destroy a competitor by simply spreading lyes or at least not prooven accusations!!!

And now, last but not least, here is the OFFICIAL registrated DESING RIGHT pictures next to each other! Why were thy never presented to police and the judges? Whats wrong with EU law? Are we talking about free market or rather an illegal persuasive way of stopping oir business on a free market?

Patents and desingn rights are an respectable way of protecting an invention or a unique design! Clearly patents and design rights shall not be abused to prevent free competition and actually improvement of of goods and innovation! THis has been stated by EU law and is valid around the world!



We wated to fit all immages on one page. The proportions may not be 100% correct. However, anybody can clearly see that IAQUA STINGRAY  is not a 1:1 copy of SEABOB and also not the same design, in the light of DELFJET beiing the original modern dive scooter pre existing design! 

Keep in mind that Granddaddy DELFJET is the "original design", all numerous other old dive scooter designs also form the existing art pool (remember James Bond 1960 in THUNDERBALL , and even every hydrodynamic submarine and boat are the base for above dising variants!

We conclude clearly that IAQUA is 100% legal and CAYAGO has to pay us a 186.000€ damage for having the police confiscate our products and block our business this entire season!

By the way, we imported those goods with all legal documents, CE papers, papers and we paid already VAT on it! So Spain government has already made profit on fake goods! How is that possible while CAYAGO has literaly illegaly taken the products with help of a "lawyer" and presuaded police!

What a mess!

We had no chance to prepare above TRUE desing evolution / explananton to the police! THey simply took our goods and messed up our boat show completely!

We still can not belive that this has happened in EUROPE!
