REDBACK
SCALED DOWN TECHNOLOGY
Size matters. Not only a kid’s sail, the RedBack is designed around the ergonomics of the smaller rider. Lower clew and boom cutout, as well as lower skin tension, to suit lighter weight sailors. By matching the rig’s geometry with rider height, control and performance are enhanced.
This is a real flexing sail, built on scaled down technology allowing even the smallest sailors to push their limits. It is sold as a package for simplicity and compatibility. Or as separate components, all designed around smaller rider ergonomics.
Sizes 2.6 and down use 3 battens for minimal weight. The larger sizes, 3.0 to 4.7 are based on the S-1 with 4 battens for improved stability and wind-range. All sizes use premium eM3 materials for maximum performance.

TECHNOLOGY
/ HYPERSPIDER 4.0
/ SPIDERFIBRE


SEAMLESS HEAD PANEL
This high abrasion area is made from only 1 panel and does not carry any exposed seams, preventing any potential weak point in this area. As a result, seam creep and seam-related failure have been eliminated.


EM3
eM3 is developed to combine the performance of the e-series cloths with maximum durability.
The use in the upper panels reduces not only the overall sail weight but also the swing weight, aiding manoeuvrability and control. Used in the BLADE and in the FREEK.


DOUBLE SEAMS
All Severne wave sails have 25mm double stitched window seams. The wider, single colour seam tape ensures maximum tear strength and crash resistance

BOOM HEIGHT REFERENCE
Boom height gauge for ease of reference.


THERMOFORMED TACK FAIRING
Protects your board from impact and neatly covers the foot detailing. It incorporates the rope stash pocket for easy storage of your downhaul rope.


MOLDED SOFT EDGE
With recessed grooving, covering any vulnerable stitching the moulded soft edge encloses the hard edge long the foot of the sail and protects the stitching from wear along the board non-skid.


SPIDERFIBRE
A web of fibreglass filament that disburses loads across seams and throughout the body of the sail. By using stronger, lighter fibres and reducing sail patching, we can measurably reduce weight and swing weigh and at the same time, increase strength.


EM4 HIGH LOAD LAMINATE
Based on the proven eM3 platform, the high load eM4 material features twice the amount of X-Ply fibre and increased film thickness to maximise durability. This new material allows weight reduction whilst maintaining puncture resistance and tear strength. Used in the lower impact zone in the sail.

SEAMLESS FOOT CONSTRUCTION
A single panel in the foot area with hidden load patches and zero exposed stitching eliminates seam abrasion and seam creep in this high load area. Maximum durability and minimum weight.
