Vortex AIR

Mistral Vortex AIR sup hardboard

Our Vortex Air inflatable goes way beyond mere focus on the materials, but equally, if not more importantly, upon the construction and engineering, in order to create a board that is genuinely more efficient in the water representing a true advancement, not merely marketing nonsense. This is an exciting design shift away from normal, by which we aim to elevate the status and performance of the inflatable SUP – most of all, we’re proud to say, we are pioneers and leaders in this field and intend extending and perfecting the concept further.

The net result, nets faster more efficient boards, with the built in added security of secondary buoyancy roll chambers, added stiffness and an altogether improved paddling experience. Paddling an inflatable, need no longer be low-tech and slow, but genuinely better by design the Mistral way.

The primary hull chamber at 15psi – 18psi and the new construction, permits for an extra rigid construction, with much improved rail shape, being more edgy and hydrodynamical efficient.

Rigidity and weight, are factors iSUP makers have obsessed over, but it’s time now to consider efficiency and speed over water, for effort put in by the paddler. With our new 4 chamber boards, we’ve been able to isolate differing structural areas of the boards in order to control and manipulate each area, something impossible to achieve with a single chambered board.

The hollow nose cowling (bow), is also of low psi (1-2psi) and functions to improve water flow-off, when punching upwind and added buoyancy when paddling downwind. The nose is deliberately not pointed, but made blunt, to ensure added volume in this area. All in all, the nose area is hugely more efficient than conventional shovel nosed iSUPs or even round or pointed nose evocations. Our design concept, is truly unique and fit for purpose.

The independently inflated side rails, are low psi hollow chambers requiring just 4psi and provide secondary buoyancy, acting as stabilisers when the hull rolls, permitting the primary hull to be narrower than usual, due to having the added security of these elevated side rails.

By incorporating independant side wall chambers, with an independent high density drop stitch
flooring and layering over with PVC we are able to create ‘chined’ edge unique to our stand up
paddleboards. This improves laminar flow of water and the directional stability of the board overall.

Rigidity is hugely improved over conventional one chamber SUPs being as the primary high pressure
hull can be very much more narrow and more compact which improves the torsional properties of the
chamber itself, the low pressure upper and outer side chambers, providing secondary stability when

Special notes
Available in 2 different widths. Our 25”, the upper side chambers running nearly the length of the board, increases the width to 28”, while our 28” board equates to 31” at the outer side chambers. These only engage when the board rolls, otherwise they sit just above the waterline, thereby not contributing to drag.

Avoid over inflation of the bow chamber (1-2psi). Over-inflation will cause deformation of underside.
Only inflate to be ‘touch hard’. Side rail chambers inflate to 3-4psi only.
