Review : Seventhwave wetsuit Viper 3/3 Ti G&S ZB Steamer

Seventhwave Wetsuit Viper 33 Ti G&S ZB Steamer

If there is Only one thing to UNDERSTAND about this suit, it is this:
« 70% #38 Neoprene: Super durable neoprene from the chest down makes the Viper extremely durable and long lasting. »

You only have #39 super stretch yamamoto neoprene in the arms.

So what does that mean exactly.

Well it means that given the material used, the primary objective of this suit is to be DURABLE and to outlast anything in the market.

It certainly can but at the expense of something we are all used to these days: Flexibility.

This suit definitly lacks of flexibility from chest / under arm area to the ankles.

At this price point, you’re buying longevity.

Personally, I rather spend more and get also the stretch, like I could have with a MAX 3/3 ti in their range for example.

It had to be resent to seventhwave for some minor change in the collar and leg length. Collar was too long by 2cm and legs by 3cm.
The entry system is Not Great. It’s the same concept in all their models.

It’s far from perfect because it extends so much the material that there is a statement in their FAQ that it will tear down:
« I have only worn my neck entry wetsuit a couple of times and there is a small tear in the front of the neck. Is that common?

This is common with all our Neck Entry wetsuits.

The neck entry panel on all ZB (neck entry) models is the most vulnerable panel on the whole wetsuit. This is because of the high stretch required for the entry and exit process to get your body through this opening.
Over time and with use it will fray and tear a little around the neck.

We recommend leaving the tears as they are covered up with the collar. Even if they get quite big they do not compromise the performance of your wetsuit.
… »

Yeah this is a major panel and neck entry design flaw right here…

The suit fits everywhere like next to skin compression garment. It’s tighter in some areas than others though. For some reason the upper body felt generally tighter than the lower body (like with my MAX 1.5mm).

Maybe it’s the measurements, maybe it’s the tight fit option I choosed.

The other thing is their panel construction in the lower legs and knee, as you can see in the picture. It’s just weird. It fits correctly though.

Given lack of flexibility, I would recommend this model for every watersports exept surfing.
If your focus is on durability. Look no further.

Review : Seventhwave wetsuit MAX COMP 1.5mm Mens Ti FL ZB Steamer

Seventhwave Wetsuit MAX COMP 1.5mm Mens Ti FL ZB Steamer

Real 1.5mm thick yamamoto rubber #39. Killer rubber. Add to that the ultra thin jersey lining.
The lining is not that silky smooth nylon you can be used to with every manufacturer nowadays. It’s more of an heavy duty type of jersey. Probably more resistant but not as nice on the skin.
The suit is all you can expect globally from a custom yamamoto wetsuit so I will only comment in the little flaws.
This was a custom suit, (you can also order general sizes).
The wetsuit had to be sent back to seventhwave for some minor change in the collar. It was too long by 2cm. They say their customer like super long collars...

The entry system is NOT Great. It's the shoulder panel with a round hole in the middle. Not the champion of chest zip wetsuit entry system, that's for sure.

It’s far from perfect because it extends so much the material that there is a statement in their FAQ that it will tear down: (check pic)

Yeah this is a major panel and neck entry design flaw right here…

You could think that with such a design it will be hard to put on and off. Not particularly if you're used to neck entry wetsuits.

I have to say it has a positive aspect though: it doesn't put any stress on the stitchings near the shoulders. One of the usual problems with neck entry suits from other brands.

And yes even with care, it starts to fall apart after a couple sessions. Ok it’s not a big issue but they should get to work on their panels, given the price tag.
I made peace with it but not everybody will.

The suit fits everywhere like next to skin compression garment, I asked for a tight fit (they recommend going only "firm" fit). It’s tighter in some areas than others though. For some reason the upper body felt generally tighter than the lower body.

In fact there maybe another small design flaw right here. the underarm and torso panels are made in such a way that you have the impression that the stitching circles around your chest (in reality it does not). Because of the center panel in the torso and in the back, and the stitching around it, the suit FEELS like a bit restrictive.
I mean, when I bump my chest to the maximum, I feel some restriction.
I do not recall feeling this in the water though.
Maybe it’s the measurements, maybe it’s the tight fit option I choosed. Maybe it's both.
What I think is that if the panels were designed differently and if they simply removed that front and back center panels, it would make sense and certainly allow more stretch in that area.

Anyway, don’t get me wrong, I pointed out some things to improve, but that MAX COMP 1.5mm Mens Ti FL ZB Steamer is a BOMB with no competition for now.
If I were on the market for a new summer wetsuit, i’ll buy one again for sure but ask for a firm fit (not tight).

Review : Ocean & Earth Aircon Longboard Board Cover

Ocean&earth Aircon Longboard Board Cover

This is the best longboard boardbag i've had so far.

Design, materials, engineering, everything is spot on. Really this is a steal at that price compared to FCS offering. It's in line with the creatures of leasure and Pro-Lite offering. S U P E R B.

It oppens almost all the way to the nose.

Balance isn't perfect though, but maybe because I use a 9'6 bag for a 9'4 Aviso longboard that is lighter than your usual longboard of that size.

So, I will not complain on this. I don't have any other board to test the balance.

The only flaw for me is the fin slot. The expandable tail with the air nest system works well if you have a big center fin, that extends the cover, the down side is the tip of your fin directly rips on the fin slot zipper. I don't like that.

The other downside is that if you let the fin through the zipper opening of the fin slot, then it's not that extended anymore, loosing much air flow by the look of it...

Last thing on the fin slot, if you choose to let your long Fin through the zipper, if the boards move inside the cover during handling, this could damage your fins.
My 10'0 is inside and FCS cover that has a scratch fin slot. much better in that aspect. A review will follow.

This fin slot is a bit of a bummer, but this is such a perfect longboard bag in every other aspect that I can live with it and would certainly buy another one if I had to.

Review : Fyn Genome adac system surfboard fins

Fyn genome adac system surfboard fins

This will  NOT be a quick review, simply because there is so much information it is just not possible.

this is so different, so new, so advanced, so techy, that I felt I needed to write about how I felt using them session after session, because it’s definitly something that you need to get used to.

In my review, I will simply state their claims without any tech informations, please check their website (type "fyn genome" in your preferred search engine) as they cover all the details behind their patented work and tech, most of it is in french though, so use a traduction app or browser module.

These are the futures model, the Pro version (hard flex) recommended for my weight after a nice and quick call.

It was a gift so I couldn’t choose to go with FCS. I have 4 boards in my quiver to try them on, but none of them is a "latest design" shortboard. I got a 6’6 Rusty shortboard, 6’6 rocket fish John Johnston, a Linden compressor 6’8 and a Don Johnston monster 7’2 shortboard. I’ll get the FCS version if I’m stocked so I can try it in more performance shortboards / newer designs.

First session:
It was a head high day at the beach break, tide was high and lowering, 95% of the waves were quick closeouts with a high current on the face making it hard to catch waves. I only had my rusty 6’6 x 19,6 x 2,5 on hand, maybe a tiny bit too much board, I feel a 6’2 at 33 liters would have been perfect for me. Anyway, I wasn’t at my best physical fitness so I ended up catching only a couple of waves during the session.

One of their claim is that it helps you paddle. I did not feel any drag paddling at high speed to catch a wave or getting back quickly to the line up to avoid unecessary duck dives. Do you feel any drag? NO. Do they help? I didn't feel it honestly.

What paper say isn't necessary noticeable.

Also, you know those days the waves are a bit flat or kinda mellow, you paddle, miss the wave, and you are under the impression that you missed it by very very little. Well it felt like this did not happen or could not happen. There is also that " bogged " feeling you have at take off sometimes when trying out some different fins on your board. I did not feel that either.

The overall feel that I can put a word on is fluidity and unrestriction in some way.

It’s like a skatey feel or like an absense of feel, like « Do I have fins? ». You feel it’s gonna slip and it doesn’t, you hope it’s not gonna hold and it does.
They’re doing their job unoticed.
It’s the strangest, not feeling them like you’re used to.
It’s like you can do what you want and they got your back but without you feeling them.

I'm asking myself, did you feel lack of precision? I don't have the answer yet. Come back here later for an update.

STRANGE and great altogether, Hopefully some clean sessions will come soon with some more feedback and some more radical and pushed maneuvers.

Second session with a 6’6 rocket Fish JJ mounted in single fin:
Too loose with the single fin...
The guys at Fyn recommended it in one of their email. I tried it but it won’t be my go to set up.
On a powerfull bottom turn, I pretty much got the same feeling as my first session: it loosly holds. You feel and think it’s gonna slip and it doesn’t. Wih only one fin on the back...
I can't really explain it but this set up was completly off for me on the board. I'm not a single fin lover anyway. Will try the 3 fin set up next time.

Third session with a 6’8 Linden compressor: I used the longboard fin (big size one that is supposed to go on 9’0 to 10’0s).
Knee high to waist high fast waves.
I was impressed by how little I was feeling the Fin. I regularly have a 7’5 Greenough 4-A Volan on lock down with this board which I feel is the best of my experiments so far. Well honestly I did not feel I had something else, and especially not something SO big… Exept for a better hold during tip time with some mushy sections that should have wiped me out (I think). I don’t really know what that say’s about the fin right now. I’ll keep having sessions with it and report more. A second session with the fin and I’m starting to feel a bit slower maneuverability (longboard like), feeling I do not have with a smaller fin where I can slide and place the tail where I want right after take off. I felt like I had a hard time doing that. Starting to think that the fin is definitly too big for the board. I want to try the board with a twin set up next. They don't have any small size longboard fin.

Tried the longboard fin on my 10" Pearson Arrow cj nelson noserider and My 9'4 pearson arrow cj nelson performance longboard.

2 sessions, knee high to waist high, months apart, on the 10" in less than great waves, so I have to keep riding the fin...

I probably have to get used to it but the only downside I see is like on the linden compressor, placing the tail right from the take off, I can't do it like i'm used to and want to for now. I'm not talking about a bottom turn. I generally like to take off and while still up on the face of the wave, quickly sliding the tail so I can go right to the nose, no small bottom turn positioning... Well I have a hard time doing it, seems slow and hard, maybe because thee's not enough speed or something. While nose riding the hold is pretty amazing I DEFINITLY feel the difference, it handles the mush like no other fin I know. When I think about it, i'm almost tempted to quantify saying it holds better by 20% or more. Once you're speeding down the line maneuveurability is great. I'm tempted to say better but I have to try it more.

1 session on the 9'4.

Waist high + session, apart from my lack of fitness, it was great. had great stability on the nose! Even if the Fyn is supposed to let you turn without having to be in the rear position, on a longboard, long bottom turn with lack of proper legs compression ends in the water. I can honestly say I would have been down far quicker with the Futures performance 9'0 single fin I know well on this board. The hold is something.


New surf sessions and…

It all clicked for me on these fins!

It’s almost like if the material needed some braking period of 10 hours + of surf to really start working flawlessly like intended by engineers.

New session on the 9-4 high perf longboard.
Speed, maneuverability, hold, really better than my single 9 performance futures fin on these aspects, I want to try a thruster option!!!
Less problems to make the fin release right from the start at take off, but ain’t what I’m used to, maybe I’ll Finally learn how to do it. But the fin beeing pretty large…

Still better overall than a conventional fin. Have to put it on the 10" now to see if I feel the same benefits.

Mellow waist high + session on the Aviso 6’6 JJ fish at around 40+ ltrs


The waves were getting flatter on the inside (really flatter) and I would NEVER have passed those sections with regular fins and especially on this board. I’m not exagerating, only a longboard would have made it, and probably not all of them.
I’m talking 5 seconds REAL flat section here. The kind of which pumping won’t do anything for you.

Instead of pumping and pumping I was surfing the flat section working the fins (snaking) and generating speed with ease allowing me to surf the reform to the beach. I was almost maintening my speed, almost.
I’m not saying this because it happened one time and I’m impressed. I took 5 waves at the end of the session (tired) in the exact same spot and conditions and everytime the same result. More or less speed, but still surfing till the beach.

What is even more crazy is that I have this Board since 3 years now and I’ve been struggling to make it work. S T R U G G L I N G. And that’s why I put those fins on it in the first place, because I knew that it was a real test. That board was SLOW, hard to turn, like heavy under foot (in fact it’s very light, think firewire FST light) just the kind of board in your quiver you take when you’re not in perfect shape and you want the comfort of some volume, after a time out or a sickness, but you know it lacks performance big time.
I just tried to convince myself there was no problem with the shape. I tried every set of Futures blackstix, AM1, F4, EA, rusty’s, Al merrick version of MR TFX, futures Solus. A bunch right?

Yes some were better than others but nothing made it work like I wanted it to, The best option was Solus and Al Merrick AMT with trailer.

Until today.

It’s become lively!

On the take off the speed generated was like if I were on a TOMO MPH shape, NO JOKE, the control, hold and vivacity were amazing on the face of the wave.

Something clicked, with the board and with the fins.

I had my fare share of epiphany, finding just the right fins for a board and having a blast.

NEVER like that.


I can’t wait to try them in head high + conditions, hopefully before summer 17.
In the mean time, I’ll be surfing the 10-0.

I just bought a Firewire TOMO Evo. Can't wait to test it with the genome fins.

I had the pleasure of testing their emergency system by a beautiful day!

It saved the fin box on my one week old Firewire Tomo Evo... No sign of stress around the box, no delam, just a very tiny dent due to that metalic pivot exploding on impact.

I have yet to have some real good waves to report on how it goes on that kind of shapes.

Something else rather important. I had to deal with their customer support. I won't give any specific detail on the reason why because every problem can be specific to a user, it's use of the material and what happens to it in or out the water. That said, Their customer service is AMAZING (from a US customer service point of view, not a French one !), Very understanding & quick solutions. A pleasure.


Got myself the small single fin model for my linden compressor 6'8 minimal (the big one for LB's was just too big)

Well this Small Fyn single fin is now on lock on the board. It was already an amazing board with whatever fin you used Greenough 4A, kai sallas, thruster, almost everything worked fine especially the 4A. The Fyn is at another level. It's just unimaginable, unbelievable how much it can change how you ride and how the board behave.

when you step on the tail, the board spins like a skateboard on wheelie! No joke.
on a 6’8 mini longboard mounted on small aprox 4’5 single fin or on a tomo evo with a thruster set.
The feeling is more extreme on the tomo, in fact on the tomo the spin sensation is almost the same as on a skate. Almost. Less radical on the 6'8 obviously.

on the 6’8 Pro 2017 us box model:
you can place the tail during take off exactly as you want and where you want without loosing speed (those take offs on speedy beach breaks when you don't have time to go for the bottom turn). fin slightly upfront in the box.
Hold during noserides is amazing, maneuverability is perfect when you keep the rear foot just in front of the pad. When you step on the pad, THE MANEUVEURABILITY IS   N E V E R   S E E N   B E F O R E. Almost Like skatebording on the 2 rear wheels. Yes I say it again cause it's really crazy. The Pivot is really extreme for this kind of board. Demands some getiing used to. The limit is now Your abilities, not the board nor the fins.

You have a feeling that you can control the position of the tail on the wave like if you were gliding without fins and with footstraps. It’s like the fin is just here to hold and is the extension of the leg. I just can’t imagine for now what the possibilities are.

Last wave of the session I was turning from the nose ride position with ease and flow just by slowly leaning on the sides.

Just want to get back in the water for more.
Sessions after session those fins keeps amazing me more. My surfing level has improved or maybe it's just the material that allows me to surf better or do things I never could before.

Again, more will follow soon. I'm still waiting for decent overhead conditions.



The Masterminds at Fyn explains some more : (This is a google traduction of emails received in answer to my questions)

The principle behind those fins is to reduce the efforts needed to provide maximum efficiency.

This traduced by minimal efforts needed to obtain a rotation, without loosing your line.

It’s not necessary anymore to be on the 1/3 rear of the board to make radical maneuvres. You benefit from that energy savings to ride the board more upfront, exactly in the right spot to gain and keep velocity, using your rail game to accelerate or carve.

If you keep your foot on the back, you can rotate the ADAC ™ leading edge orientation system with your back foot, this increases the rudder effect that rotates the board on itself, as in slide, But without stalling or braking energetic.

This positioning on the rear therefore allows the figures of sliding of the rear. But the ADAC system on our fins saves effort and therefore needs less to be positioned backwards to maneuver, to fully use the rebound effect and maneuverability generating speed, it is optimal to surf more forward (the flatter and fastest zone of the board).

It is strongly advised to use boards with a wide forward point (in front of the middle) to take advantage of more use of the front foot, because the wide points back serve only to maintain lift on back foot meneuvers, Decreases the speed capacity of the board. Our fins abolish the obligation to over dimension the rear surface because they offer you the maneuverability in advanced positions ...

Fyn dynamics fins have NO cant, they’re engeeneered that way.
It does not mess with futures fins box systems where cant is given by the fin. We carried out the calculations of the projection of the lift force with and without cant of 3 ° to 5 ° to evaluate the real gain of the cant and it turns out that the theoretical difference is a few tenths of Newtons.

We further consider that the cant parameter is canceled by The antagonism of the two opposite side wings, And that it is a very "aesthetic" parameter whose impact is negligible. We opted not to take it into account and simplify it.

The effect of drive (acceleration) supposed to be improved by the cant, is more of the good shape and angle of the fins than of its cant, and we worked on this hydrodynamic aspect which is the most Effective and which provides gains of several newtons on the Maneuvers.
exemple videos test: d.mp4?dl=0)

On the other hand, we advise shaper using the fcs to put Central plugs without cant on all boards for boards equipped with FYN fins. We also recommend not to put a Toe angle (pinching) because the fins adjust themselves automatically and simultaneously for all fins.
They can be mounted on boxes with a toe angle, but It is less efficient than the theoretical optimum.

To be precise about the influence of the cant: The difference in force between a fin with cant of 7 ° and a fin without cant, holds in the projection of this force. Using force vectors and trigonometry, the corresponding result to the difference between the hypotenuse and the adjacent side of a triangle rectangle of angle of 7 °, It is therefore the cosine of 7 °, this amounts to 0.992, so a force of 1 Kg optimal strength with cant will be transformed into a force of 0.992 Kg Without cant, so less than 1% difference.
Let us add that the antagonist fins cancels the effect in opposition.

If you have 5 position on your Fish 6.6, I recommend 3 settings Depending on the conditions and your style or mood of the day:
1: twin front mounting: small waves great maneuverability
2: rear dual mounting of quad positions: Less maneuvering but useful When the height rises above 1.5 meters, or you need support from 2 fins in the verticality to ensure the trajectories (this Configuration may not be possible if the boxes have been mounted Of different depth.
3: only one fin in maximum center rear position: Maneuverability and we have a really nice boost in the faster waves, yes a single fin is really a good feeling to test!

Overall what changes compared to habits taken with fins Static:
Surf more ahead of your usual foot positions of about 15 cm, You will still have a very great maneuverability. With the dynamic fins, no need to go for the maneuvers on the back foot which slows down the board, stay on the fast, flat area of the center of your board, and enjoy from this committed position to intuitively launch your maneuvers taking advantage of the board feeling that sticks to your feet in your rotations.

Use the full length of the rail in your curves, as in Snowboard or parabolic ski, and insert Snake movements into your Boost pump ... surf more intuitive and fluid than ever!

This requires some sessions to be fully exploited because maneuvers are anchored in our reflexes, and it is difficult to change habits.

At the level of the shape: A board with an advanced wide point is useful to take full advantage of a speed generating position, an outline with more parallel rails are possible thanks to the gain of maneuverability, this allows better use of the rails in the fast zones. (Better immersion over a longer length) Assembly of the lateral fins without toe angles (parallel) is recommended for a constant synchronization of the fins. This makes the board easier to understand in its rotation, reduces the drag and exploits the stimulus effect of maneuvers or snake optimally.


The ADAC Fins virtually never « release » like a conventionnal fin because the more weight you put on them the more their incidence and their camber adapt to maintain a good lift / drag ratio.

On the other hand, if you put a lot of force on a fin with a strongly backward position, it will interpret this as a will to pivot the rear and adjust its angle and let the excess force turn the board like a rudder.

Depending on the power and style of the surfer, it is necessary to adjust the resistance to the incidence of all the fins:
3 classic fins series will have the resistance of incidence of two fins pro series.
But the resistance to the rotation of the back of the board was deliberately diminished to save the surfer's energy and to steer the board from the flat area of ​​the middle of the board. So if you find that the rear is too free it is because the rotation is facilitated by the auto incidence.
To harden the rotational behavior, the center of gravity of the surfer must be moved away from the pivot point made by the fin. For this 2 levers: advance the center of gravity of the surfer or and retreat the fins.

It is also possible to harden the rotation by increasing the number of fins or by using a harder version (the rotation resistance is modified by the internal structure of the ADAC system)

The « slide » is not a direction taken by the back of the board under the effect of "rudder", this component is desired, it is controlled and is limited by the distance between your center of Gravity and center of the fin (theoretical point representing the pivot point created by the fins). To limit this displacement (acceleration producer) it is necessary simply to advance on your board, or to retreat the fins. This effect is clearly sought after and desired, but it requires boards with widepoints advanced to be fully optimized.

The idea is to look for naturally ondulating trajectories around the spine without needing to retreat to turn.

It is therefore necessary to block this reflex to link the rotation with a recoil of the body on the fins related to the style of competition figures expressing the power of the athlete seeking the valuable and necessary note of the jury.

Stay in the advanced position on the board even in your turns, they will then be producing speed and will allow you to place more figure or take off higher up in the same space with less muscle energy expenditure.

The extreme 180° cut back is the ideal figure to reveal the work of the dynamic fins, the usual cut back cuts the inertia of the board and the surfer when the body is placed on the back to pivot, the advance on the wave is consumed by this slowdown, and it is necessary to quickly rebasculate on the front to regain control of the trajectory by regaining speed...

With elastic Greenough-type fins, with Flex, energy is stored by pressing more strongly than normally in the turn to have a spring effect when exiting the turn, but the "hydrodynamic" problem is that the energy surplus flexing the fin like a spring, then generates the release (in the hydrodynamic sense with loss of lift and increase of drag braking). Our job was to think this type of maneuver in terms of hydrodynamic efficiency. This consists in obtaining the maximum effect with the minimum of energy: one turns flat without effort added, this turn is a producer of speed and one finds himself at the exit of cut back with a pivoting realized in a very short radius, without effort with a gain of speed produced by the fin. We then sequence the following maneuvers without needing to relocate the foots and the weight on the board and with an advance usable for the fluid reading of the rest of the wave ...

Overall, there is a fluid maneuver in constant acceleration. It is an exercise that requires a different placement, and a real understanding of our system because the maneuver must be reinvented in terms of weight distribution on the board, to take full advantage of the advantages of the genome fin. On our side the theoretical and technical work of optimization of the performance is realized, now it is the surfers to invent the new figures exploiting this gain.

For the twin fin option there are two elements to be taken into account

1: the toe angle:

Our dynamic fins adjust their angle according to the impulse,

The ideal is not to put an angle of toe with our dynamic finss (all configurations) in the way of Simmons with very remote fins a.1381498792141067.1073741827.100008428779429 & type = 3

2: the aileron load:

When turning radical in twin or thruster, quad, the antagonistic fins (external to the curve) are removed from the water partially or totally (ventilation of the fin). The weight of the surfer and his inertia are thus concentrated on a single fin (or 2 for a quad) So if you accumulate an angle of toe + an overload of the fin you will have a dynamic fin that pushes the board on the inside strongly. The recommendation is to mount the fin in twin in the Simons way (we place the fin on the side near the rail to keep it still submerged but it is oriented parallel to the core of the board and as far back as possible to have a good propulsive sweeping effect, but for 85 kg you will need 2 fins (per side of turn) to collect the load, so a quad mount is necessary for powerful surfers of your size who take out half of the fins Off the water in their maneuvers, but if the style is cool and the antagonistic fins do not come out of the water, then twin fins are enough.
