In 2022 we introduced the world's first windsurf sail made of recycled material, the RE-SEAL. The RE-SEAL is made of up to 75% polyester film from recycled PET bottles, depending on the size. By switching to recycled material, each square meter contains about 10 recycled PET bottles, saving an additional 400 g of CO2 per m² in material production. In terms of design, features and performance the RE-SEAL is identic with the SEAL and does also live up to the well known Gunsails quality promise. Thanks to the large wind range, the 4-batten Core Wave sail can offer both and convinces with its playful handling with just the right mix of drive and neutrality: The SEAL pulls through the turns with momentum and switches to neutral in a flash when riding the wave.
KEY FACTS: > The lightest GUNSAILS wave sail > 100% X-Ply / Square-Ply and Kevlar Warp Laminates for the most extreme demands > Two-piece mast foot protector offers more protection for mast and board > Optimal mix of drive, control and neutrality > RDM compatible only
The current SEAL retains its uncompromising wave character. It takes off dynamically at launch and then balances itself in the wind as if on autopilot. Its precise ON/OFF behavior when riding waves, the agile handling even when powered up and the active twist recommend it for every type of waverider. A revised profile on the lower battens with an update of the mast sleeve now provide an even lighter feel, more elasticity in maneuvers and more control. The slightly longer mast curve and short boom give the SEAL its stretched outline, keeping it harmonious and controllable in all wind strengths and guaranteeing excellent overall handling. The generous use of 3 mil square-ply gives the Core Wave sail its reputation as the lightest wave sail in our range. Its features are of the highest level and at the same time guarantee durability. According to the windsurfing press, the SEAL is one of the absolute best all-rounders, so we guarantee the perfect fit for you!

SAIL TECH
A GUNSAILS windsurf sail is a combination of selected and high-quality materials, combined with years of experience and construction knowhow. Sail designer Renato Morlotti is responsible for the performance and quality of the sails. In his working environment he has optimised everything down to the smallest detail. Every piece of material in the sail is continuously improved in terms of durability and weight savings. Only a closer look reveals the quality, good manufacturing and durability of a GUNSAILS sail.
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.
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.
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.
TENSION FRAME
The Tension Frame forms a functional unit with the smart clew construction. It holds 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 it improves the response of the sail and increases the profile stability. The stability of the construction ensures long term
consistent sail characteristics.
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.
REDUCED BOOM LENGTH
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.
REDUCED BOOM LENGTH
For wave and cross over sails as well as for the freeride sail Zoom, a concave cut is used
from the batten above the boom to the clew, reducing the distance from the mast to the clew.
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
To ensure the functionality, easy handling and durability of our products, we have developed various features over the years and established them as our standard. The dedication and precision of our sail designer Renato Morlotti are once again evident in the individual details. An important factor that makes our quality possible and distinguishes us from other sail brands.
F.R.E.D.
F.R.E.D. will help you to find the optimal downhaul trim for your sail. The mark is located 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.
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.
MAST FOOT PROTECTOR
The new two-piece mast foot protector offers more protection for mast and board. The loop makes it easier to pull down the sail.Through an opening, the uphaul can be conveniently guided inside the protector. There is a mesh pocket on the inside. Excess rope etc. can be stowed here.
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.
OFFSET CLEW
Horizon and Raise sails are equipped with two clew eyelets which are set asymmetrically for individual tuning. > Upper eyelet for more power > Lower eyelet for more control
POCKET GUARD
A PVC braid sewn onto the bottom batten pocket protects the sail from abrasion when waterstarting.
STRAP ON
After rolling up the sail, simply attach the bungee rope and the sail can be stowed away easier and is 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.
TEST REPORTS
SURF MAGAZIN / SEAL 4.7
Thanks to Variotopp, the new Seal can also be ridden on a 400 mast - the 370, however, is our recommendation. The Seal gets by with only moderate loose leech, the trim point in the top points the way. With Hack, you can also pull in a little more loose than recommended as a heavyweight. Also because the 2023 Seal has been given noticeably more power on the sail hand, the sail gets up to speed well and is very stable in the hand. Even without pumping and perfect planing technique, the sail finds the right angle of attack almost by itself. On the straight it then also acts powerfully, the pressure point is nailed down - annoying retrimming remains the exception. When riding waves, the sail always provides a noticeable basic pull on the sail hand (drive), which helps to arrive at the wave lip with a lot of speed in limp conditions. On the other hand, the Seal is no longer one of the most playful sails that can be directed through maneuvers and loops with two fingers.
surf conclusion: The new Seal has been tuned more powerfully again and scores as a gliding, uncomplicated and balanced sail, especially in the wave and for freeriding. For freestyle and maneuvering fans, however, the 2022 Seal even has the advantage.
DESIGN: The Seal features a strong Dacron presence in its mast panel, which is widened in the top area. Its outline is semi stubby and the leech has a cut at the end of the center batten. The sailcloth is made entirely of X-Ply. Also available in a RE-Seal version made from recycled PET bottles.
ON THE WATER: The Seal's luff tension is smooth, although the mast bend is prominent. The cloth maintains leech tension by following the trim indicator, which is fairly close to its leech edge. At the boom, the tension must be evident. The rig is lighter than one might have imagined, and is very respectably in the good midrange. The Seal has a balanced profile with a pronounced hollow across the boom. Propulsion is available quite early. The pull in hand is moderate with a touch of tenderness in the responses. For a 4-batten sail, the whole is particularly stable and well behaved in a straight line. When riding waves, it offers control of progressive traction with minimal pressure in the hands at all times. This allows you to approach the lip without losing momentum. The Seal is much more agile than the Horizon, but still controllable, but less responsive than the most extreme models. We used it on thrusters rather than quads to avoid having to reduce pressure underfoot. This model is an all-rounder that adapts to a wide range of conditions.
CONCLUSION: The Seal offers a balance between stability and agility, a good mix of versatility to be effective in both jumping and wave riding. The soft reactions show a real comfort. The Gunsails is a model accessible to all levels without being overly crazy. The Seal is suitable on a waveboard of an advanced rider who wants to try all kinds of conditions.
+ Drive, versatility jumping/surfing, price - Too little craziness for the expert
WIND NEWS / RE-SEAL 4.7
When we finally found the bread and butter to test the Seal 5.3 2022 in the form of waves and wind.... the Re-Seal 4.7 2023 came into our hands prematurely. Given the delay in the last two issues of Wind News, it is therefore better to propose the test of the latest sail spontaneously. The Re-Seal was actually already a coveted sail for last season's testing, but between delivery delays and the "shortage" of this eco-friendly version of the Seal, made from laminates of used polyester appropriately recycled and converted into X-Ply, nothing had come of it. Until a few days ago, when the special edition Seal in size 4.7 and with its special 'green look' reaches our great hands. We've already talked about the special design in detail in previous issues, so we'll just mention it briefly here, but at first glance, apart from the color, there are no obvious differences from the basic version of Seal! The shape confirms that it is the same model, but made of different, environmentally friendly materials. There are no surprises in the trim either: The GunSails recommendation for the Re-Seal 4.7 is the RDM mast, and if you want to use its full potential in the waves, the best combination remains the RDM 370/17 with 27/29 cm extension, given the 397 cm mast pocket. Considering that GunSails uses the Vario-Top on this size (as on 3.2, 3.5, 3.7 and 4.0), we also tried to upgrade it with the RDM 400/19 and the combination was not daring at all, on the contrary! Especially if you are 'used' to the basic version... the Re-Seal 4.7 seems a bit more elastic and 'softer' with the 370/17, which is perhaps due to the materials used in the construction. This characteristic is already noticeable when rigging: With both masts, it is indeed easy to achieve the right luff tension to find the optimal trim, but in the water, especially with the RDM 400/19, you feel the sensation of a sail that is light in the arms, while with the 370/17 it is softer and more suitable for particularly windy conditions. While not the most powerful wave sail, the Re-Seal 4.7 surprised us with how well it handled in the wind holes and how much power it could deliver at low speeds when trimmed appropriately in the boom. It may not be a versatile and stable "engine" like the Horizon, but it doesn't deviate much from it, and besides, it pays off in terms of maneuverability once you get into "serious" waves in strong winds, where it's even more responsive when it needs to be, but neutral in the surf at the right time. It leaves as a dominant impression that of great lightness and agility. A wave sail for experts in the sector, responsive and agile, robust and powerful, perhaps a little more "elastic" than the basic version, but equipped with the necessary stretch to be exploited even in our waves. The price/performance ratio is still unbeatable and the solid construction with the X-Ply equipped window that allows a good visibility, combined with the robustness, protects the sail in the roughest wash.
Plus: Quality/price, construction, relatively powerful, maneuverable and responsive in the surf, soft feel, eco-friendly.... Minus: Less comfort than the Horizon in very strong winds.
PLANCHEMAG / SPÉCIAL TESTS / SEAL 4.7
A wide range of use
The lightest sail of the brand, after the wind blows in, has a pronounced profile behind the mast, with a nice twist in the leech, reinforced by different X-PLY materials lighter in the upper part, and a Dacron panel behind the mast.
ON THE WATER: The Seal has been redesigned to be lighter over the last two years and creates a nice forward push to get planing quickly. It is softer than a Horizon, but remains relatively firm in its handling with a very good overall balance when sailing. It is one of the most efficient and powerful sails in this group when it comes to positioning yourself quickly on the water, sailing high on the wind, slashing waves and keeping in planing. It offers good, balanced support on both hands and a super feel at the top of the range. It covers a wide range of conditions, is more versatile than average and appeals to a wider audience. It has a less pronounced, less exclusive character than others in this group and is more accessible and tolerant, for example, in the settings. In the wave, you have a good pressure in the front profile area to push the edge of the board into the turn with a good guidance, without neutralizing as naturally as some others, without being so light and reactive in ON/OFF. The advantage is that you still have some pressure on the back hand to accelerate or go back up to the lip of the wave at side onshore, and less dependent on the good will of the wave.
CONCLUSION: This Seal has scored a lot of points for handling different wave conditions in France, thanks to its good compromise between stability and maneuverability. It is always present, even if some would like it to be a little more neutral, with a very nice range of use in the result.
+ Price, range of use, performance, stability/handling, versatility - Less pronounced ultra-reactivity.
WIND NEWS / SEAL 4.0
Considering that GunSails' sail range for the 2024 season remains virtually unchanged compared to this year (more on this in the news on page 20), for this test we have taken a size of Seal, the company's four-batten wave sail, which is somewhat unusual for a test... 4.0! A size that in my case (I weigh 82 kg) is the "combat" size, which allows me to easily do without the 3.5, also thanks to the 340 mast, which makes everything more tolerable, but which in the case of lightweight Andrea (he weighs 67 kg) is a sail size that he uses much more. As already shown in the test of the Re-Seal 4. 7 (we are talking about the version of this sail made from recycled material ... ) in the December/January 2023 issue, the Seal 4.0 also feels a little softer than before. The sail, which is the lightest in the GunSails range, has been further slimmed down and now reaches the weight of wave sails that cost much, much more. However, the solid construction to which the German sailmaker has accustomed us for years has not suffered. Incidentally, the Seal still relies entirely on X-Ply windows!
On the water ... Andrea came back ashore after 4/5 sessions on a thundery day, with rain, wind for a 3.5 and very long wind holes where you wouldn't even have planed with a 5.3 and said ... "This sail is not even remotely related to mine! How beautiful!" For the record: Andrea uses my three year old Seals in sizes 4.2, 4.7 and 5.3, and the Seal 4.0 that is the subject of this review was rigged with the Reptile Reverse 340, which I strongly advised him to get with a view to buying the 3.5 in the future! After using both the Reverse 340 and the 370 on the GA IQ 4.0 and then on the Gun Seal 4.0, I found that the shorter mast made the sails much more "docile" and easier to handle, even in super-sailed conditions. Ideal mast or not ... the Seal 4.0 is a good compromise between stability and maneuverability, it is more versatile than the previous models and this feature makes it "usable" for a much wider audience than just experienced surfers.
It may not be due to the softer mast that this Seal is slightly less responsive than other wave sails, but only the most experienced wavers will notice this... while the little bit of extra flex pays off in pretty much all conditions. When surfing, the Seal has the advantage of always delivering a good pull, allowing you to accelerate at a reasonable speed and attempt cut backs even when the wind under the shore is not pushing as it should. This ability is particularly appreciated in side-on shore conditions and is a good card to play in local swell. A more accessible sail than expected, for all advanced riders who want to surf in all conditions.
