SUNOVA FOIL 4-IN-1

F.R.E.D. will help you to fi nd the optimal luff trim for your sail. The mark is found in the upper sail window and serves as an orientation point to create the perfect luff tension (loose leech).

The large reinforcement at the sail top avoids abrasion and wearing out whilst rigging.

The top opening is enlarged for an easier mast insertion. The adjustment buckle is placed behind the mast; unnecessary webbing can be stowed in the top opening.

Lightweight mini battens take control of the leech while twisting and avoid detrimental leech fl utter. In this way, the window fabrics are spared and the longevity of the sail is predefined.

PVC tabs on the upper batten pockets prevent wearing out and abrasion whilst rigging.

The Internal Trim Batten system is completely integrated into the batten pocket and the battens can stay tensioned in the sail. The profi led end piece offers additional protection against abrasion.

A PVC braid, sewed on the bottom batten pocket, protects your sail from abrasion while uphauling and waterstarting.

The Reduced Boom Length design shortens the boom length. The handling is much easier and feels more compact. The sail control is signifi cantly improved. A shorter boom is generally stiffer and will assist in maintaining the sail stability and profile.

The Wave sails are equipped with 2 clew eyelets which are set asymmetrically for individual tuning:

Upper eyelet for more power
Lower eyelet for more control

The boom length is printed beside the clew. The mast lenght is patched on the mast protector.

The printed height scale at the boom opening helps you to easily remember your personal boom position.

Double seams form the most stable connection between individual panels and different materials. They are used in stress zones as well as in areas of high tension and make your sail robust and durable.

All seams in the significantly stressed foot area are protected by Dacron coverings. A PVC edging from foot to the first batten protects the leech edge against your board’s nonslip coating.

The integrated triple pulley has large easy turning stainless brass rolls which greatly reduce the effort required for sail trimming. Also, if you prefer, the rolls are removable to allow the use of standard downhaul pulley hooks.

The GUNSAILS logo that is sewn on the sleeve keeps it open at the boom opening area like a clip and thus mast insertion is much easier.

For very easy packing away and storage: Just roll the sail up and fix the elastic retainer.

On the inside of the protector you will find a closable mesh pocket which can hold e.g. your downhaul surplus.

The large mast foot protector can be pulled back whilst rigging. The loop eases the initial pulling down of the sail. The uphaul can be comfortably inserted through an opening in the protector.

The well designed combination of different materials allows weight savings without losing stability. By varying the stretch behaviour of the individual materials, we can precisely define each sail profile under pressure and guarantee you consistent sailing characteristics over the long term.

The Tension frame forms a functional unit with the smart clew construction. It is built from multidirectional x-ply and framed with insignia. Therefore it can resist maximum stress levels. The Tension frame receives the force from the clew and distributes the tension with the additional warp lines into the sail. The layout of the tension frame is designed to support the individual profile of every sail. Conclusively the tension frame improves the response of the sail and increases the profile stability. It also ensures long lasting sail characteristics and improves the overall durability of the sail.

Double Seams provide the most stable connection between panels or different materials. They find use in areas of high material tension and make your sail tough and durable.

The Smart Clew Construction is based on the tension specific and precise alignment of different materials. The result is an extremely durable clew area without additional weight. Depending the sail the layout of the materials varies in order to suit the resulting tension lines in order to distribute the force from the clew, towards the Tension Frame into the sail. That helps to create more response, better profile stability and long lasting sail characteristics.

Through the selected use of kevlar warp laminate, we are able to precisely define the stretch properties of every sail. This leads to more response and a long lasting and stable sail profile. The light and unidirectional kevlar threads show very low stretch, even under highest loads. They are individually positioned in each sail to suit its range of application, leading to long lasting performance and sail characteristics.

Multidirectional X-Ply is used in high stress areas. The thread layout shows a higher density of polyester yarn, thus making the material more resistant than the regular X-Ply. The additional vertical thread direction allows the material to take more tension and force in the critical tension line.

The square ply is based on the same concept as X-ply material. However the threads are aligned in a 90 degree angle and the material offers a higher overall thread density. That allows us to reduce the thickness of the included monofilm to save weight, but ensure durability at the same time.

X-PLY the all time classic of the reinforced laminates. It is light, stable and has a good transparency. Therefore it is used in the window area of the Wave-and Cross Over Sails. X-Ply also does withstand higher punctual stress. In case of a cut, the threads avoid further damage because they stop the cut from spreading through the window.
