The Seal is our brand new 4 Batten Compact Wave Sail and already a team’s favourite. It exceeds the expectations of a compact wave sail. It is light with an absolute neutral feeling but delivers more performance than the previous Blow model.

With a new outline, new mast curve and new positioning of the battens, the pressure point changes slightly towards the back hand. This configuration allows the required drive in combination with perfect sail balance.

The new concept also stands out with its on/off capabilities. It is absolutely neutral while riding the wave, but delivers a lot of power when needed.

With the use of the light Square - Ply Material in the top, the sail feels extremely light and stable at the same time. The perfectly adjusted loose leech with an additional mini batten, ensures control through the whole wind range.

A direct and playful drive, light sail feel combined with a unique riding stability allows the Seal to be the perfect all round wave sail.



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



The Gun Sails 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.



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.



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.



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



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



The new High Density X-Ply shows the highest thread density of our used materials. It combines the characteristics of the square ply with the ones of the regular x-ply. Together they form a highly resistant and durable material, which is light at the same time. HD X-Ply finds application in the upper panels of our wave and freemove sails. The area including the material is specifically designed to suit the range of the sail. The result is an especially stable and reactive leech construction.



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.



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.



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.



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.



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.



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.



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.



Mostly used on the flatwater range due to a lot of surface in the boom area. The longest batten of the sail starts below the boom area, crosses the boom line and ends above the clew. The crossing batten does stabilize the profile, which is extremely important in that area. Like that the sail is more effective in acceleration and pumping and has a more stable pressure point.



The alternate positioning of the battens on the back and the front of the sail leads to a more equalized tension- and weight distribution. This arrangement will provide you with the exact same sail feeling, independent of the direction you are riding.

SURF MAGAZIN 1-2 2018 / SEAL 4.5


Whoever misses the Blow will probably find a suitable replacement with the Seal. With the latest power wave sail you can choose your individual trim. The luff remains at best moderate, whether it is then rigged with much or little clew tension, the sail has pull and drive as it should be with a compact power sail. Powerful, good planing and with a lot of power on the wave. Only in the upper wind range you can clearly feel the higher pressure point, which gives the sail a nice long radius. It pulls the drive through the turn for a long time, ensures best board speed even if there is no push from the wave. On the other hand, this much power in hands reduces the variability and ease of wave riding. The Peak is the more suitable choice for particularly deep launching and then a correspondingly fast uprighting of the rig. With onshore wave rides and correspondingly less sailing work, this is of little or no importance. The seal scores - under all conditions - with the large range, even whit high wind it never flutters, but only twists in the leech. This makes it always very controllable with pleasant softness. On the straight it is even more stable and less sensitive in the hand than the Peak. For heavier surfers it will probably often be the better choice, but as a larger surfer you have to get used to the slightly lower clew.

surf tip: Power package with a lot of drive and a very large wind range in one trim and in total



DESIGN: The Seal is the new, compact four-batten sail from GUNSAILS. Even in this size, it gets by with a 370 mast and is thus fully in the tradition of its predecessor Blow. However, the Seal has not much more in common with that predecessor than the short luff. The short boom and the hardly pre-profiled battens point in a completely different direction. But one thing about the Seal as we are used to from GUNSAILS: the equipment. Like all GUNSAILS wave sails, the seal is completely monofilm-free, X-Ply is standard on large areas and the well-protected seams are also standard. In the top, loads of narrow mesh but rather thin x-ply is used over a large area. The large loose leech is particularly striking, sticking out above the short boom. The battens show hardly any pre-profile and one should not give the Seal too much loose leech, the power can be regulated better by the clew.

ON THE WATER: Already at the first meter the Seal heralds a new era of Compact Wave sails from GUNSAILS. Super agile it lies in the hand and would rather be strictly led, in order to start planning then at least properly. However, the seal does not match the plane performance of a Peak or Transwave, this applies to both the early planing phase and the full planing. Here, especially heavyweights have to pay tribute to agile handling. The loose leech opens wide and the short mast cannot hold the profile; the loose leech is also less helpful when jumping. But the seal seems to have been made for other things: With a little wave power in the back, it immediately shows where its strengths lie. It is pleasantly easy to conduct on the wave and can also be excellently set "off" for tight turns. Moves on the lip are no problem with the Seal. Especially in the modern style of wave riding, with an upright sail and a lot of work on the Finns, it finds its home. Here, the pressure point further back and neutrality pay off.

CONCLUSION: The GUNSAILS Seal is a radical sail for wave riding. It is agile, neutral and fits well to the skateboard style of modern waveboards. However, especially heavy riders reach their limits with the rather mediocre planing performance, here the Peak offers a better overall package. The Peak is also the better sail for riders who attach great importance to jumping.




DESIGN: The Seal is the successor of the Blow in the category 4 battens Compact sail. GUNSAILS announces a completely new developed sail, new batten position, luff curve, outline and a slightly flatter profile above the boom.

ON THE WATER: The seal has a fairly deep and tight profile at the front and bottom of the sail, but in your hands you can feel a balanced sail with power and a wide range of use. In fact, there's no waiting for the power, the rear hand can be felt when you need it, for example to glide, to pass through wind holes or to go upwind. In waves this is often helpful to accelerate immediately after a manoeuvre or on shallow water. On the other hand, the seal remains stable even with increasing wind, so you can controle it to the max. The handling is good in the wave, but you can still feel some leverage in the upper part of the sail, where it has more surface. Its potential to neutralize (OFF) when the sail is open to relieve the rider in turning manoeuvres or cut backs or other modern moves has improved compared to the Blow. The responsiveness is there: to vary the power, to change direction or also to switch quickly from full throttle to neutral or to tilt the sail in manoeuvres from front to back or vice versa.

CONCLUSION: GUNSAILS is making undeniable progress in the materials used and the look and is presenting a new, interesting model that combines the modernity of a responsive compact profile with finesse in handling and a powerful, stable profile with performance and a wide range of use in all conditions. The Seal will not be the most playful sail, but given its qualities and price, it cannot be a bad choice for a rider who wants to equip a Compact Multi Fin Board.

+: Range of use, balance, versatility, price
- : Slightly more leverage

PLANCHEMAG 10-11 2017 / SEAL 4.7


The new Seal comes from the Blow and is completely revised. It has a slightly more central profile, a new outline and the battens have been repositioned, but it remains a compact sail. A new, thinner mesh material reduces the weight of the sail top, the main window is made of wide mesh X-Ply material and the mast panel is made of Dacron.

ON THE WATER: This new seal has quite a lot of drive, it is light with a forward pressure point that pulls forward and in the middle of the hands. The profile is more central than the old Blow, less pronounced in the front, with a more stable pull on the back hand, giving you more freedom when riding the waves. It accelerates strongly and you can build up pressure on the board in the wave, but it also pushes the board nose down a bit more than others in choppy water. It is not the softest, it already has a somewhat direct profile and dynamic acceleration with just the necessary dose of softness to be comfortable, this feeling is enhanced by the big Loose Leech. You don't take the gas away as fast as with other sails, there is always a basic speed with which you can accelerate again, which is supported by a good stability.
It is a compact sail that feels light in the hand and offers a good trim range over the clew to adjust the profile fuller or flatter. If you opt for the upper clew eye, you can also get a little more dynamics and lift. It is well balanced, although not as stable on long rides as its sister Peak with five battens, the Seal aims at wave riding, pure, classic surfing, with a strong acceleration in the bottom and good traction in the curve.

CONCLUSION: Light and playful with sufficient stability, the seal accelerates powerfully in the smallest gust and offers a permanent pull, which is a good argument in wind holes and when going straight. It delivers powerful performance when you need it, but stays light and playful on the crest of the wave on your back hand. With its wide range of use you are successful at all spots.
