A NEW ERA
The 2021 vintage of our 4-batten wave sail is more than just a small update. The Seal changes from a Compact Wave sail to a Core Wave sail. Improved control, consistent performance and a more pronounced OFF make it the perfect allrounder for all wave conditions. What we haven’t changed are its exemplary features and legendary durability.

WHY SEAL 2021?

With a new, stretched outline, the Seal takes it to the next level. The luff has been elongated in all sizes and the boom shortened. As a result, the sail is now even lighter in the hand and can be controlled even more directly. But it is not only the changed sail geometry that contributes to the light feel of the sail. For 2021 we are increasing the proportion of 3 mil square-ply and are now launching the lightest GUNSAILS Wave sail ever on the market.
The Seal maintains its highly praised mixture of drive and neutrality, but through accurate fine-tuning, the OFF has now been highlighted.
Fast, agile and easy to turn, with these characteristics the new Seal masters every wave intuitively. With its active twist and the new plus of control you keep the overview even in extreme wind and can concentrate on the next maneuver.
The Core Wave sail for hardcore conditions.


STANDARD SAIL FEATURES
In order to guarantee the functionality, easy handling and longevity of our sails, we have developed various features over the years and made them our standard. The individual details show once again the dedication and precision of our sail designer Renato Morlotti. An important aspect that makes our quality possible and distinguishes us from other sail brands.
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.
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.

GERMAN SURF MAGAZINE CONFIRMS
With a noticeably lower weight, shorter boom and softer profile, designer Renato Morlotti wants to have noticeably improved the handling and neutrality of the Seal. However, you don’t have to do without the usual GUNSAILS features such as the Fred trim aid. The Seal offers very moderate trim forces on the luff, you trim independently of the wind up to the mark, the adjustment to the wind range is then primarily done via the boom trim. The Seal feels damped and comfortable, but never feels spongy even in the hands of heavy surfers (>85 kilos), even on the 370 mast. The sail stabilises immediately in the planing phase, is well-balanced in the hand and develops above-average planing power. Fortunately, the 2021 model turns out to be noticeably more manageable than in the past, both on the straight and in manoeuvres. The Seal also convinced us on the wave, as it still offers enough drive to reach the lip of the wave with enough power even in sluggish conditions, but now also more neutrality and lightness in flat trim, which noticeably expands the range of use for side-offshore waves and freestyle tricks.
surf conclusion: Planing performance, control, handling - the GUNSAILS wave sail now plays in the top group all over the place! Balanced like this, it turns out to be a loyal companion for strong wind freeriders, trick surfers and wave surfers alike.

SEAL VS HORIZON


EQUIPMENT DIFFERENCES
SEAL: 4-Batten core wave sail. Balanced mix of drive and neutrality with more OFF than the Horizon. 100 % X-Ply.
HORIZON: 5-Batten power wave sail with a deeper and more direct profile, which looks a bit stiffer due to the 5 battens. 100 % X-Ply.
SAIL CHARACTER
SEAL: Allround wave sail for side- and onshore conditions. Very good performance and good pull on the back hand, fast and responsive. Balanced feeling with more OFF, it is more neutral when riding waves. The wider Dacron luff panel softly absorbs gusts and chop.
HORIZON: Powerful, well planing wave sail, rather for onshore conditions. Fast, with noticeable pull on the back hand and always some drive, less OFF. Very good control in strong winds, therefore also ideal as a storm sail on flat and choppy water.
RIDER PROFILE
SEAL: For all windsurfing levels. Great for down-the-line wave rides and jumps, tight or wide manoeuvres, even freestyle tricks. For performance-oriented wave riders with single fin or multi fin boards up to freestyle wave boards.
HORIZON: For all windsurfing levels. For powerful waveriders or heavier riders in low wind areas with a preference for jumps, Bump & Jump or even Freestyle. For large volume wave boards, freestylers or freemove boards.


“The Seal has everything a wave sail needs. It’s robust, neutral in handling and still has a power reserve to get yourself out of tricky situations.”
