FREESTYLE SAIL
The Yeah knows no limits on the water. With this ultra light and agile sail you set the rules. Two-time world champion Steven van Broeckhoven swears by the lightness and neutrality of the Yeah. Together with sail designer Renato Morlotti, the material mix was further tweaked and an additional Dacron patch was installed in the luff. This provides more elasticity, which on the one hand makes the popp more explosive and on the other hand improves the OFF.
KEY FACTS:
> Ultra light Tight leech and perfectly balanced profile for lightning fast rotation
> Kevlar Lines for durable and consistent handling characteristics
> Only RDM compatible

SAIL TECH
INTELLIGENT MATERIAL ASSEMBLY
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 sail characteristics over the long term.
X-PLY
The all-time classic of the reinforced laminates. X-Ply does withstand higher punctual stress. In case of a cut, the threads avoid further damage. X-Ply is light, stable and has a good transparency. Therefore, it is used in the window area of the Wave- and Cross Over Sails.
MULTI DIRECTIONAL X-PLY
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.
SQUARE PLY
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.
KEVLAR STRETCH CONTROL
The targeted use of Kevlar Warp laminate allows us to precisely determine the stretch characteristics of each sail, ensuring a consistent sail profile and more response. The extremely light, unidirectional Kevlar threads have a very low stretch, even under highest loads. They are specifically positioned in each sail depending on its area of use. With Kevlar Stretch Control you will permanently find consistent characteristics and performance in your sail.
DOUBLE LOCK SEAMS
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.
SYMMETRICAL BATTEN SYSTEM
The alternating arrangement of the sail battens on the front and back of the sail allows a balanced tension and weight ratio. With this feature you have the same sail feeling, no matter which direction you are driving.
CROSS BATTEN CONCEPT
Often used in flatwater sails with a big surface in the boom area. The longest batten of the sail starts under the boom and ends above the clew. In this area the deepest profile as well as the largest surface of the sail is located. The Cross Batten stabilizes this area, especially when pumping. The center of effort point remains stable.
SAIL FEATURES
SMART CLEW CONSTRUCTION
The Smart Clew Construction is based on the specific and precise alignment of different materials. The result is an extremely durable clew area without additional weight. The Clew Construction setup, which varies depending on the type of sail, defines the direction in which tension and force are transmitted from the clew to the sail, thus supporting the stability of the profile.
OFFSET CLEW
The wave sails are equipped with two clew eyelets which are set asymmetrically for individual tuning. > Upper eyelet for more power > Lower eyelet for more control
REDUCED BOOM LENGHT
For wave and cross over sails as well as for the freeride sail Stream, a concave cut is used from the batten above the boom to the clew, reducing the distance from the mast to the clew.
On the more performance-orientated flatwater sails, the RBL cut is made directly on the batten above the clew and the eyelet is shifted inwards by up to 12 cm.
POCKET GUARD
After rolling up the sail, simply attach the bungee rope and the sail can be stowed away easier and more space-saving.
STRAP ON
After rolling up the sail, simply attach the bungee rope and the sail can be stowed away easier and more space-saving.
FOOT GUARD
All seams in the significantly stressed foot area are protected by Dacron coverings. A PVC edging at the sail foot protects the leech edge against your board’s nonslip coating.
F.R.E.D.
Fast Rigging Easy Doing F.R.E.D. will help you to find the optimal downhaul trim for your sail. The mark is found in the upper sail window. Simply trim the downhaul rope until the loose leech reaches the FRED mark.
TOP GUARD
The large reinforcement at the sail top avoids abrasion and wearing out whilst rigging.
VARIO TOP
With some sails a Vario Top is used, which also allows the use of a longer mast. An additional loop is sewn on top of each sail. It serves to hook in the sail if you want to pull out the mast.
MINI BATTENS
Lightweight mini battens take control of the leech while twisting and avoid detrimental leech flutter. By that, the window fabrics are prevented from damage and the longevity of the sail is increased.
BATTEN GUARD
PVC logo labels on the batten pockets prevent wearing out and abrasion whilst rigging.
INTERNAL TRIM BATTEN
The Internal Trim Batten system is completely integrated into the batten pocket. The battens can stay tensioned in the sail. The fine adjustment ensures an optimal trim. The profiled end piece offers additional protection against abrasion. An Allen key to tension comes with each sail.
BOOM POSITION CONTROL
The printed height scale at the boom opening helps you to easily remember your personal boom position.
SLEEVE VOLUMER
The sewn PVC label keeps the mast sleeve open at the boom opening like a clasp making it easier to insert the mast.
MAST FOOT PROTECTOR
The mast foot protector can be pulled back whilst rigging. The webbing strap eases the initial pulling down of the sail. The uphaul can be comfortably inserted through an opening in the protector
MESH POCKET
The uphaul rope can be comfortably inserted through an opening in the protector.
COMFORT PULLEY
The integrated triple pulley has large easy turning stainless brass rolls which greatly reduce the effort required for sail trimming.
TRIM SETTING
The luff length is patched on the mast protector. The boom length is also printed beside the clew.
