The Racing Board RUSH CJ4 has been designed and built by JBAY.ZONE specifically for the sport lovers, who wants an easy and fast board on the water, with the right balance between performance and stability. JBAY.ZONE Racing boards can also be used effectively as Touring boards for longer or shorter trips.










To maintain great speed and smoothness on the water the shape of the RUSH CJ4 board is narrow and long to offer little water resistance thus improving the performance of this Racing SUP.


Although it is a Stand up Paddle for the pursuit of performance, RUSH CJ4 guarantees sufficient stability to feel safe and space to store objects in the front while hurtling through the water.


The Drop-Stitch HDT technology used for the SUP RUSH CJ4 by JBAY.ZONE allows the Racing Board to easily transport up to 135 Kg.




JBAY.ZONE Safety Leash light and extremely resistant. Maximum length in extension of 300cm.


JBAY.ZONE adjustable aluminum paddle Red Edition with a single polypropylene blade (83 SQ.IN – 535 cm²). The modular aluminum handle is extensible for 50 centimeters.


The JBAY.ZONE support for Action CAM with hooking like GoPRO®HERO can be installed comfortably on the Deck of the Stand up Paddles.


New JBAY.ZONE carry bag ideal to carry the SUP RUSH CJ4 and its accessories.


Bravo® 2x2000cc Manual Pump specific for SUP, ideal for High Pressure valves with bayonet fitting. Single-Action Double-Action mode selector.


Practical repair kit with laminated PVC patch to carry out small repairs for possible holes or damages to the layer of external material.


The construction made up of two superimposed layers of laminated PVC is called Double Layer and – together with the internal construction Drop Stitch HDT- allows to RUSH CJ4 to achieve a performance equal to a rigid SUP, with an excellent weight support. For the internal structure, the Drop-Stitch technology has been used: it allows that the Stand up Paddle RUSH CJ4- thanks to thousands of fabric filaments welded to the ends of the laminated PVC- becomes rigid and resistant (once the recommended pressure of 18PSI has been reached).


Even if this SUP is very long and made of Laminated PVC Double Layer, it is light, with a weight of only 9.9 kg.


Developed for speed, efficiency and control, the Racing Sup Board RUSH CJ4 has been designed giving priority to quality and performance. The hydrodynamic shape and the central fin US System Box type assure a very small friction with water without sacrificing too much space for the paddler, who can paddle with a good stability and control.


The laminated PVC, that is the construction material for the Racing SUP RUSH CJ4 is made up of 2 PVC layers and one Polyester layer to reinforce and assure a great resistance to the SUP.

LENGTH 380cm – 12’6”

A very long and high deck, with a pointed nose, as in the case of the Racing SUP Board RUSH CJ4, together with the single US Box System fin which opposes minimal friction with water, contribute to a decisive increase in performance and smoothness compared to an All Around board or a Touring Stand up Paddle.

WIDTH 71cm – 28”

The width of the SUP RUSH CJ4 is the right compromise between performance and stability. A value of this type offers a much higher top speed compared to boards with wider decks but the space for the user is still adequate to offer a certain stability and safety even if it requires a greater skill to master its control. The narrower deck reduces friction with water and increases the hydrodynamics of the Stand up paddle.

THICKNESS 15cm – 6”

The thickness of 15cm is a premium value, not common to all inflatable SUPs. The weight resistance is considerably greater and this leads to a greater stability for the user in various conditions of use.


You can use the JBAY.ZONE RUSH paddle board  CJ4 immediately : everything you need is included. High-quality accessories such as the double-acting Bravo® pump and the GoPRO®HERO support are added values to the high quality JBAY.ZONE.


The SUP RUSH CJ4 JBAY.ZONE is made up of two superimposed layers of highly resistant laminated PVC, in order to obtain an inflatable board with a performance equal to a rigid SUP, with an excellent weight support.

For the internal structure, the DropStitch technology has been used: it allows that the RUSH CJ4 J3 Stand up Paddle- thanks to thousands of fabric filaments welded to the ends of the laminated PVC- becomes rigid and resistant (once the recommended pressure of 18PSI has been reached). The Rail is also reinforced by an extra layer of laminated PVC for greater safety and resistance to impact.

The Racing SUP Board RUSH CJ4 has an EVA Foam cover on the central part of the Deck to provide extra support to the Paddler in different conditions of use. The valve used by JBAY.ZONE is High Pressure type with bayonet connection to connect the Bravo® Double Action Pump -included- in complete safety, optimizing the air insufflation operations and avoiding the risk of unexpected pressure leaks. Also for this model, D-rings are provided along the perimeter of the Deck, useful for connecting accessories such as the Safety Leash.
