The Wave Machine Seal presents itself with the well-known range of use, but does surprise with new abilities for 2020. Thanks to the redesigned geometry the 4-batten-compact wave sail shows even easier handling and improved on/off. With its vast wind range and effortless control, the Seal does not only perform in radical wave manoeuvres but does also prove amazing high wind capabilities. We could transfer many aspects from the development of the premium Wave Sail SEAL Membrane to its little brother, the Seal.

Within the redesign we changed the luff curve of the smaller sizes to reduce the body tension and optimize the adaptability of the leech. This does not only increase the control but also the reactivity of the sail. At the same time, we flattened the profile below the boom to enable direct reactivity. Thanks to the optimized profiling the sail feels even lighter in hands and has absolute neutrality while wave riding. Through the new assembly of 3 mil square ply we managed to save some weight in the upper area of the sail resulting in further improvement of the handling. Within the construction of the Seal we positioned new Kevlar lines to define the stretch properties and secure the durability of the sail.
Through the redesign the Seal jumps up to the next level and sets a new scale inside the Gunsails wave range. With its playful handling and exactly the right amount of drive, the sail is not only the first choice of our professional wave riders but also for windsurfers of all levels.

GUNSAILS | Test report Windsurf Wave Sail Seal Windsurfing Surf Magazine

With a flatter profile and less luff curve, manufacturer GUNSAILS wants to make the Seal 2020 more manageable and neutral. A label helps to find the right luff trim, the trim forces are - probably also due to the short 340 mast - pleasingly moderate. The changes on the sail show immediate effect on the water. Despite the short 340 mast, the Seal feels relatively firm even in the hands of heavy surfers - even in gusts nothing flutters or wobbles. The price of the flatter profile is a smaller loss of planing performance, which the sail can tolerate, but in return it gains a lot in other areas: draft stability and wind range in one trim are convincing all along the line, the Seal lies balanced, stable and very easy to sail in the hand - this is an advantage for both cracks and less experienced surfers. The wave riding characteristics have changed from "very powerful" in 2019 to "balanced". The Seal still offers enough power for crashing cutbacks in sideoneshore conditions, because it always keeps some basic pull on the back hand. But now it also has a minimum of neutrality for exquisite sideoffshore waves and freestyle tricks.

Surf conclusion: GUNSAILS has worked on the right screws and tuned the seal more universally. With a convincing combination of power, control, drive and off, wave surfers from Fehmarn to Fiji as well as flat water racers will now be equally happy.

ON THE BEACH: The Seal is the compact handling sail from GUNSAILS. The measurements remain unchanged for the third year, as does the exemplary feature set. There is plenty of X-Ply in the sail. In the main window it is quite large meshed to allow an almost clear view of the wave lip. Still the long batten above the clew is conspicuous. The new stitching in the top, which we praised last year - which significantly improved the seal's control and twist - has disappeared. In the upper sail panel there is now a continuous square-ply panel, which is supposed to push the sail weight further down. We experimented a bit with the rigging and trimming and pulled the luff a few centimetres further than indicated. This makes you aware of the most important innovation: If the luff is well tensioned, the lower three battens still show a beautiful, pre-shaped sail belly with a clearly pre-tensioned profile.

ON THE WATER: Directly after the start you notice that the Seal has changed a lot, because the sail is much firmer in the hand than in previous years. And so much in the beginning: This is really good for the sail! The boom is one of the longest in the wave test, which is a matter of taste and the spirits in our test team were somewhat divided. But the team around sailmaker Renato Morlotti has done its homework. If the Seal was a relatively special product with a limited target group last year, this will no longer be the case in 2020. Because it is now an entirely good sail. The planing performance has been noticeably improved, it is no longer behind others. Also the control in strong winds is now excellent. A real plus when it comes to jumping is also the top speed. It is also very impressive. We were excited to see how the sail would perform on the wave. There it's easier to hold and can be directed faster than last year. It offers a mix of neutrality and drive that tends to be more OFF when steered with the back hand. Thanks to the precise handling it can be put down very well in the bottom turn and thus be set neutral by riding technique.

CONCLUSION: The GUNSAILS Seal is a positive surprise and will be on the market in 2020 with a strong improvement. Thanks to better planing performance and controllability, it is not to be criticized as an all-round sail for any wave conditions. With a firm feel and control, the Seal is now also fun on the straight and offers precise handling on the wave.

WINDSURF UK JAN-FEB 2020 | SEAL 5.0 2020

GUNSAILS | Test Report Windsurfing Wave Sail Seal Windsurf UK

OVERVIEW: The Seal is Gunsails’ 4-batten compact wave sail, sitting alongside the five-batten Horizon and championed by notable team riders such as Florian Jung. For 2020, there is also an eye-catching Seal Membrane available - a four batten wave sail, constructed in a single-piece 0.7mil film with Technora fibres sandwiched in such a way that the forces are absorbed and dispersed evenly, leaving a light and extremely direct feeling sail. Back to the standard Seal on test and it is the only 5.0m sail here to set on a 370cm mast, its outline short and relatively boxy. Build quality is good, with x-ply of various weights used throughout its panels and plenty of detailing on show, such as beading along the length of the bottom batten, a seamless foot panel, and the tack roller oriented for easy downhaul. It was rigged for test on a 100% Select mast, although is still said to be compatible with an SDM if desired.

PERFORMANCE: Sheathing the mast easily into the Seal’s head-cap, it is clear that there’s plenty of luff curve in the sail, the downhaul nonetheless easy to apply thanks to the softer mast. Gunsails’ handy trimming guide FRED was not present on our test version, although this is due to it being one of the first off the production line; all future versions will see FRED return. Apply tension and the leech opens progressively along its length, with plenty of looseness in the ‘double mini-battened’ top panel. There is then only a subtle amount of profile in the batten below the boom, the Seal setting flat and neutral above, with both lower battens keeping rotation around the mast. In marginal winds the top clew eyelet was utilised, giving the boom a little more leverage and the sail's power more purpose. Light and easy at rest, as the wind fills the sail breathes into a deeper profile, aided by the movement in the Dacron luff panel and luff sleeve. It is also very pumpable thanks to the longer boom length, the flex in the softer mast and the amount of area low down in the sail. Once going the Seal settles into a comfortable cruising stance, the centre of effort focussed low and forward in the draft. Easy and forgiving to use for long periods, you’d be excused for thinking the Seal is a user-friendly high-wind freeride sail! The low-cut foot shape, soft progressive power delivery, and high rake to the boom angle (even more so in the lower clew eyelet) makes it a pleasure to use, and very accessible for novice sailors and pros alike. Used in heavy coastal seas the Seal can act as a blasting weapon, the upper panels twisting smoothly as the draft’s softness absorbs any jarring forces from the terrain, its low power position pinning the board down to the water’s surface and mitigating any board control issues. It means the active rider can charge out and hit ramps at will, the sail feeling compact and manageable in the air. Yet use the Seal in a manoeuvre role and you’ll not be let down either. The power provided into transition is smooth and measured rather than sharp or assertive, but power it up properly and it provides enough for most, encouraging a more flowing surf style, going wonderfully light and neutral as it is turned off mid-turn.

THE VERDICT: A compact feeling all-round contender with impeccable manners, the Seal offers soft progressive power and real versatility in its application across an impressive range. If 5.0m is your biggest wave sail, there’s the added practicality that one mast could satisfy all, and at €489, it represents excellent value for money.

Finesse and lightness in clear progress

DESIGN: This year the Gun Sails Seal continues to evolve quite a bit with a modified luff curve, a re-balanced and flatter profile in the lower part of the sail. The sail top uses 3 mil square-ply fabric to reduce weight in this crucial area, while Kevlar fibers are incorporated into the construction to control the elasticity of the sail over time.

ON THE WATER: On the water the changes of the seal are immediately visible. You feel a much lighter sail in your arms than in the past, with a different profile. The profile entry is slimmer and the possibilities to neutralize the profile are greater. The developed performance is still very correct, although this sail is a bit less forward oriented than in the last years, but still effective when planing, accelerating or in its whole agility. It is a particularly stable sail, with a pressure point embedded in concrete and which can be hold easily in strong winds. The Seal is very flexible in the top and works very well to offer a lot of comfort while surfing. In the surf, it is easy to find support on the backhand to restart and accelerate. Its gain in finesse and lightness in the sail top increases its handling and its ability to fully switch off its performance in waves for example. The responsiveness is there, and the gain in finesse does not stop you from powering up sail pressure to make a move.

CONCLUSION: All in all, Gun Sails offers a new Seal that has been significantly improved in terms of handling, finesse and responsiveness to ride modern boards even more comfortably and effectively in the waves. It gains in versatility, especially since its range of use is still quite large. A very good vintage.
