Earlier in the week I went over to the [Florida] West Coast to hunt for the Big Ugly – Black Drum. Cousin to the Red Drum.
All the Blacks this week were between 20 and 40 pounds. Here are some pictures from one day of fishing –
It was a gorgeous day and being able to stand and sight fish Black Drum was an absolute treat.
Armed with my new batch of T & A Jig Heads, I bagged three heavyweight monsters and my arms felt like rubber after the mayhem subsided.

Of course one of my fishing days would exhaust most ordinary folk but I still had enough energy to paddle behind an island, drop anchor, stick an enormous Tommy Bahama beach umbrella in the mud and stretch out for a cat nap in the W 500. When I awoke hot coffee and lunch in the shade seemed in order before the leisurely paddle back to the launch.
I hauled out onto the floating dock without getting my feet wet, washed off my gear and loaded up.

My Wavewalk got me to a honey hole! The Bass were hungry on a lake where the big boats can’t go! The Top water bite was on, what a blast! I tied on a chug bug first thing and I caught six but did not get them all on video. I did manage to get three on video By switching between a do nothing worm & a chug bug I just hammered them. They were taking both with a vengeance. What a morning!

This article examines issues related to the seaworthiness of kayaks in general, including fishing kayaks, and of sea kayaks in particular, and it discusses an alternative approach to sea kayak seaworthiness based on the Wavewalk Kayak concept, and on micronautics – the art and science of designing watercraft that are small and lightweight enough to be affected by the size and movements of one passenger.
The reader is encouraged to watch online videos demonstrating performance of Wavewalk kayaks in the ocean.
The subjects discussed here include launching, going over and through incoming waves, going over lateral waves and playing with them, surfing and paddling standing at sea, and tracking in strong wind.

1. Sea kayaking – Past and Present

“…safe on the sea is an oxymoron” Wayne Horodowich, University of Sea Kayaking

Well said!

Touring and sea kayaking were the two first kayaking applications outside the traditional use of kayaks by native people of the arctic zone. Nevertheless, after many decades these activities are still practiced by a small minority of kayakers whose number has been declining in recent years while recreational kayaking has become widely popular and dominates the kayaking scene in terms of participation and number of boats sold.
sea kayaks are faster than recreational kayaks, and paddling in the open ocean and in the surf is certainly more exciting and challenging than ‘recreational’ paddling. Also, younger generations are naturally attracted to speed and more exciting outdoor sports, so why is the number of sea kayakers small and decreasing?
Polyethylene sea kayaks are not much more expensive than the better recreational kayaks, and are for the most part equivalent in performance to FRP (Fiber Reinforced Plastics) sea kayaks, so we’ll rule cost as a valid explanation.
It seems that in order to answer this question we’ll have to first determine what’s a ‘sea kayak’ vs. ‘recreational kayak’: A sea kayak is a long, narrow, traditional sit-in kayak (SIK) in which the paddler sits while being protected by a spray skirt, while a recreational kayak is either a SIK or a sit-on-top (SOT) kayak that’s wider (up to 42″ wide) and stabler, where the passengers are not protected by spray skirts.  Modern, commercial sea kayaks differ from the native kayaks by the fact they are all equipped with seats and foot braces, and in many cases rudders too.
Since recreational kayaks are slower than sea kayaks they also have a more limited range of operation, and since they offer little or no protection to their passengers they are generally limited to more warm and flat waters.
For these reasons many sea kayakers view sea kayaks as being seaworthy boats, and in fact some sea kayakers have crossed oceans in them. However this fact is by no means an indicator of seaworthiness since people have crossed oceans in a variety of contraptions including floating skis, sailboards etc.  Similarly, the world record for the longest unicycle trip is 9,136 miles but we doubt this fact would inspire anybody to switch from bicycles to unicycles…
But are sea kayaks really seaworthy, and if indeed they are why do the overwhelming majority of kayakers prefer recreational kayaks? If sea kayaks were indeed seaworthy shouldn’t we expect most kayakers, or at least a bigger number of kayakers to adopt sea kayaking as an outdoor sports activity?
Apparently, the vast majority of kayakers do not perceive the narrow sea kayak to be seaworthy although it offers superior speed and is constantly advertised as being the true and ultimate kayak.  Sea kayakers are likely to find this incomprehensible, but to most people the idea of being trapped in a narrow and unstable boat that offers the ‘Eskimo Roll’ as an only safety option is perceived as similar to being handcuffed to a motorcycle that has no breaks: It’s an equivalent to a death trap. Interestingly, the number of people who practice board surfing is many times bigger that the number of surf kayakers, which is extremely small. This means that under similar conditions surfers prefer a board to a kayak that requires both a spray skirt and a helmet.

Are the majority of kayakers right about this? Is the saying ‘Vox Populi Vox Dei’ valid in this case?  This article will attempt to examine the seaworthiness of sea kayaks from a number of angles.

2. Seaworthiness and Capsizing

“For us the definition of a seaworthy kayak includes being “Forgiving of the most egregious paddling and judgmental errors.” John Winters, ‘The Seaworthy Kayak’

Indeed, this is a most seaworthy definition!

Look outside the kayaking world and ask yourself the following question:
-“What type of small sea vessel needs to be seaworthy?”
There can be a number of answers starting from sailing crafts to inflatable rescue boats, but all these examples would have one thing in common: their stability, and more specifically – lateral stability.
Why?  -Simply because all boats are narrower than they are long, and therefore small boats are particularly narrow, that is highly unstable and prone to capsize. The ways to deal with this problem are multiple, from weighted keels in sailing boats to very wide beams in traditional ‘cats’, rescue boats and some big canoes, but these solutions are not applicable in kayaks.
Kayaks belong to a group of watercraft that are just a little wider than their passengers, and weigh even less than them.  We like to call the field of nautical design of such very small boats ‘micronautics’.

Ask naval designers if they would consider a boat that’s prone to capsize as being seaworthy and you can be sure to get a categorical ‘no’ as an answer. Those of them who will remember the existence of those little boats called kayaks might add -“Well, maybe if you’re an experienced sea kayaker then a sea kayak could be seaworthy for you, to some extent”

Sea kayaks are faster than most paddle crafts and speed is a good thing in terms of seaworthiness: Slow kayaks that are hard to paddle expose their users to fatigue and could make it difficult or in some cases even impossible for them reach to their destination under unfavorable weather and/or water conditions.
But the sea kayak is a singularity in the micronautical world since it is the only seafaring boat that offers less lateral stability than what is required to maintain balance without constant, active intervention from the passenger/s.
This puts the sea kayak in an extreme position – that of offering little or no static (form) means to prevent capsizing.  In practical terms it is a watercraft designed to capsize.
sea kayakers might find this definition somehow harsh, and point to the fact that sea kayaks are designed to be rolled and not to be capsized.  The problem with this argument is that rolling is not a prevention strategy but a recovery strategy.  In safety terms sea kayaks simply don’t offer considerable means of prevention other than their passengers’ skill in balancing the boat, and therefore are seen as unsafe – a term that’s is commonly perceived as the equivalent of ‘not seaworthy’.
In response to this sea kayakers and sea kayak designers may point to the origins of the ‘Eskimo Roll’ as the native arctic people’s solution for the safety issue, and therefore as a ‘natural’ and acceptable one.  We find this argument to be weak for a number of reasons:

1. Although kayak designs are at least hundreds and possibly thousands of years old, it seems like some of the original kayakers had their own doubts about the usefulness of the ‘Eskimo Roll’ as the primary or optimal measure of seaworthiness and preferred to exercise more caution by relying on form stability.  While kayaks in Central and Western Canada were used mainly in rivers, lakes, estuaries and generally in protected waters, Eastern Canada kayaks which were designed to be used in the ocean were wider and stabler, up to 82 cm (32″) in width:

“The Inuit of Baffin Island, northern Quebec and Labrador used kayaks that were more or less flat-bottomed and relatively wide, characteristics that contribute to stability. With high, rising prows that helped to override the waves, these relatively heavy kayaks were well adapted to their primary function: hunting waterfowl and sea mammals in the open sea.”
‘Native Watercraft in Canada” – The website of The Canadian Museum of Civilization

2. The Labrador Inuit people used long sea kayaks with a 23″ beam, which should have made them easy to roll. However, these skilled sea kayakers chose not to rely on the Eskimo Roll:

“These huge kayaks were up to 24ft. long and had a beam of 23 in. They were never rolled by their occupants, and in the event of a capsize the paddler would need assistance from a companion in order to get back into this boat”
-Derek Hutchinson ‘The Complete Book of Sea Kayaking’ (1995.. Old Saybrook, Conn.: The Globe Pequot Press, Inc., p.166).

3. Native peoples’ kayaks were never equipped with a seat while all present-day sea kayaks are. This makes the latter both less stable and more difficult to roll than native kayaks.  On top of this, the average contemporary North American sea kayaker is significantly taller and heavier than the average native arctic kayaker was, a fact that further reduces the sea kayak’s safety from both stability and rolling perspectives.

4. For the vast majority of modern paddlers the Eskimo roll is impossible to practice and therefore not a safe option.  In fact, even seasoned sea kayakers can ‘miss their roll’, especially in emergency situations:  It’s one thing to roll your kayak in a pool with nose plugs on and the water around you perfectly still, and quite another thing to roll it in the surf after you’ve been slammed by a breaking wave and hit the bottom with your head  There are countless accounts of experienced sea kayakers who occasionally ‘missed their roll’, which indicates that the common perception of the Eskimo roll as being unreliable is anchored in reality.

5. Over the years sea kayakers and sea kayak designers have developed a ‘sea kayaking philosophy’ that seems to have turned things around: The highly undesirable situation in which you are trapped inside a narrow and unstable boat that you can’t even hold straight without keeping your paddle in the water has become justified by the glorification of an extreme, dangerous and unreliable recovery technique that requires endless, tedious practicing that wouldn’t even guarantee results in real life conditions.

6. A common sea kayaking myth links native kayaks to long journeys at sea, but it appears most native kayakers used their kayaks for short trips and only the Greenlanders used their kayaks fro long coastal summer expeditions:

“For long trips the umiak, and more recently the whaleboat, are used“.
Hawkes, E.W. 1916. The Labrador Eskimo. Canada, Department of Mines, Geological Survey, No. 14, Anthropological Series, pp.71-73.

“The other type of aboriginal boat, the kayak, was used by the men for short trips and for hunting“.
Taylor, Garth.  Labrador Eskimo Settlements of the Early Contact Period. Publications in Ethnology. No.9. Ottawa: National Museum of Man.  1974. pp. 39-40.

We conclude from these data that most native kayakers were well aware of their kayaks’ limited seaworthiness. The exception of the Greenlanders can be explained simply by the fact that extreme climatic conditions forced these people to stretch the use of their kayaks and rely more heavily on them.

“A sea kayak’s seaworthiness is entirely dependent on the paddler.”  –
We found this sentence and similar ones in a number of sea kayaking websites.
It seems to summarize the situation where kayaks that are not seaworthy naval or common standards have become synonym to seaworthiness, so much that they are called as a group ‘sea kayaks’
Is it any wonder that sea kayaking has not grown to be a widely popular sport and has been continuously receding in recent years while recreational paddling in stable kayaks is popular and still increasing in popularity?
Unfortunately, some sea kayakers don’t perceive people who paddle other types of kayaks (e.g. recreational, SOT, W) as ‘real kayakers’ since they don’t roll their boats. These sea kayakers erroneously identify rolling with kayaking and vice versa.  Unfortunately, so far such attitude seems to have resulted in further alienation of the broad public from sea kayaking.

3. Seaworthiness from a sea kayaker’s perspective

In the first part of this article we examined the question of sea kayak seaworthiness from a general perspective of safety, as viewed by the overwhelming majority of boat designers, boaters and paddlers. In this section we’ll examine the seaworthiness of the sea kayak from its own cockpit, in performance terms, and while comparing with solutions offered by the new W Kayak concept:

Pitching
“…Because the pitching inertia varies as the square of the distance from the center of rotation … tremendous forces are involved and their reduction is advantageous.” -John Winters, ‘The Seaworthy Kayak’

Pitching is the vertical rotation of the boat around its center of gravity (CG). Pitching causes significant increase in residual resistance (Rr), especially when the kayak goes through waves – The longer the kayak the greater the loss of energy because of pitching.
All mono-hull kayaks are constrained by the need to place the paddler in a fixed position in the center part of the hull’s longitudinal axis.  This puts a strict limitation on the kayaker’s ability to control his boat’s pitching.  However this constraint is nonexistent in W kayaks where the kayaker is free to travel forward and backward along the longitudinal saddle inside the cockpit and thus distribute his/her weight ad hoc where it is likely to be more needed in a proactive manner.  For example, when facing waves coming from the direction of the bow it is highly advantageous to place yourself at the back of the cockpit and thus lift the bow. This would not only be helpful for riding up the wave instead of smashing right into it, but also in reducing the impact and loss of momentum when descending on its other side.

Rocker

Rocker is a must in monohull sea kayaks since without it the boat won’t turn well. But rocker also decreases the monohull sea kayak’s ability to track, and therefore its potential speed and by that its seaworthiness since speed is a good thing to have in terms of seaworthiness.
Both tracking and maneuverability are desirable in terms of seaworthiness, and the unwanted tradeoff between them is typical of monohull kayaks only:
W kayaks can turn effectively by having the W kayaker lean into the turn, which means That W hulls don’t necessarily need not be curved vertically to offer rocker. This, among other reasons enables W kayaks to perform the impossible in terms of monohull kayaks, which is to both track and turn very well and without requiring a rudder, which is a considerable source of drag and added complexity in operation.

Primary and Secondary Stability

Monohull sea kayaks are designed for speed and for rolling.  These two requirements make them very narrow below and above waterline, and therefore lacking in both primary and secondary stability.  There is no way a monohull kayak can be fast if it is wide.

Most kayakers are impressed with this Wavewalk’s kayaks unrivaled primary and secondary stability »

Tracking and Rudders

Monohull kayaks, including sea-kayaks track extremely poorly in currents and under strong wing, a factor that gravely reduces their seaworthiness. For this reason, nearly all sea kayaks come outfitted with rudders or skegs, which help their users track at a price of additional, unwanted drag that slows them down.

Wavewalk’s twin-hull kayaks are different since they require to be outfitted with neither rudders nor skegs. A W kayak can track better in strong wind thanks to its two thin, parallel hulls, and the fact that their user can easily relocate the kayak’s center of gravity (CG) for and aft along the saddle, thus determining whether the kayak would point into the wind or away from it, and by how much.

Storage

“Part of the storage problem …has always been hatches.” -John Winters, ‘The Seaworthy Kayak’

Adding weight above the boat’s center of gravity (CG) is undesirable, especially if this weight has no means of its to balance itself… This is why the optimal storage solution should offer the possibility to store things as low as possible.  Since a monohull sea kayak must have some rocker the bottom of its front and back hatches will inevitably above the hull’s lowest point, which is in its middle section…
On top of this, sea kayaks generally offer a very limited storage space so that sea kayakers often find themselves obliged to attach gear on top of their boats. This is bad for stability and not particularly good for the gear itself.
Wavewalk’s kayaks don’t present these problems since their hulls can have a straight bottom, and they offer far more protected storage space than the biggest ‘expedition’ sea kayak does.

And last but not least, hatches are prone to let water in not only when the kayak is overturned but also in wavy sea, when water flows over the deck.  This is not just a storage problem but can also quickly become one of speed and maintaining proper control over the boat.

‘Narrow beam vs. wide beam’ or ‘speed vs. stability’

“Does this mean that narrow boats are more seaworthy than wide boats? Absolutely not. So long as the boat can be heeled to present a favourable attitude to the waves the adverse effects of beam can be offset.” -John Winters, The Seaworthy Kayak

Unfortunately, most of us don’t look like we would have wanted to look, and most monohull sea kayaks are not 18″ wide as sea kayakers would have liked them to be for speed sake.  In fact, most sea kayaks are wider simply because even for experienced and dedicated sea kayakers the narrowest monohulls are too unstable for practical purposes.

Since speed is relevant to seaworthiness we would like to refer the reader to another article on this website, which discusses speed factors and particularly the effect of the beam on total resistance (drag): https://wavewalk.com/blog/2015/07/19/kayak-speed-basics-the-twinhull-advantages-and-the-principles-of-w-kayak-design/

To make a long story short, stability is desirable in sea kayaks as in all other boats – big or small.  The problem with monohull designs is that they can’t be made both stable and fast since one has to come on account of the other.
This constraint of speed vs. stability is nonexistent in catamaran (twinhull) designs, and since W Kayaks have twin hulls they can be made to be both very stable and very fast.
This has two implications:
1.    sea kayakers who are willing to give up their reliance on the Eskimo roll for a very stable kayak would be able to do so without having to give up the speed that is so dear to them.
2.    More important is the fact recreational kayakers wanting to go on longer trips and paddle faster without giving up the higher stability they are used to could do so and paddle W sea kayaks that are as fast as ordinary (monohull) sea kayaks and offer a higher level of stability than recreational kayaks do.

Kayak Seaworthiness and Comfort

“Sitting with stretched legs feels comfortable for a little while but cramps are sure to follow if you cannot get good circulation.” ‘Choosing a Sea Kayak’, Article by Vaclav Stejskal

Seaworthiness and comfort are two terms which are closely linked. An uncomfortable sea kayak is dangerous as its paddler might develop fatigue, leg numbness, cramps and back pains that could put him in jeopardy and create a severe problem for other paddlers in the group.
The reason why present-day kayaks are equipped with seats and foot braces is because unlike native kayakers, present-day kayakers are unable to sit and paddle in the L position without support for their backs and feet.  These support elements known as ‘seat’ or ‘lumbar support’ and ‘foot braces’ or ‘foot rests’ are the source of various ergonomic problems that directly affect safety and therefore are strongly related to seaworthiness.
sea kayaks are particularly narrow and offer no way for the passengers to change or even modify their sitting position in case a problem develops while paddling. Consequently, the overall seaworthiness of present day sea kayaks is being further reduced.
These poor ergonomics typical to monohull sea kayaks are in contrast with the ergonomic solution offered by W Kayaks, which includes a number of interchangeable comfortable positions.

Paddles and the Bio-mechanics of Kayaking

Some sea kayakers erroneously believe that shorter paddles offer a better bio-mechanical solution and therefore the longer, 9 ft paddle commonly used in W Kayaks are less ergonomic.  Since this issue relates to propulsion efficiency and fatigue it belongs to this article’s subject.
These people’s error is double:

1.    The paddling positions in W Kayaks offers more leverage on the paddle, which makes it easier to use a longer paddle i.e. to move the paddle faster. A longer paddle enables applying longer strokes aft while making a better use of the W Kayaker’s own weight, and thus minimize effort.

2.   The original, native kayakers themselves sometime used very long paddles, as the following quotes teach us:

“The Labrador paddle (pau’tik), is double-bladed, like the Greenland type. It is quite long – 10 to 12 feet…”
Hawkes, E.W. 1916. ‘The Labrador Eskimo’. Canada, Department of Mines, Geological Survey, No. 14, Anthropological Series, pp.71-73.

“…paddles in Baffin Island could reach 110 inches” -Chuck Holst ‘Making a West Greenland Paddle’

Do you have any questions for us?

The term ‘Lumbar Support’ appears frequently in discussions about kayak fishing and paddling related back pain. The underlying assumption in those discussions is that the lumbar area of your back (lumbar spine) requires adequate support, and if such support is provided your back pain will disappear, or at least become tolerable.

What is the Lumbar Spine?

Here is a short definition we found in a dictionary:

(lumbar)

▸ adjective: of or relating to or near the part of the back between the ribs and the hipbones (“Lumbar vertebrae”)

As you can see, the lumbar spine consists of rigid vertebrae and more flexible cartilage between them. This part of the spine supports the combined weight of the upper part of the body, including the torso, head and arms, and it is normally supported by the massive structure of the hip bones below.
In other words, in its natural state, there is nothing that pushes, holds, or supports the lumbar spine from any direction except from its top and bottom, and what holds it in this normal position are the muscles around it.

How Did the Lumbar Spine Become a Problem for Kayak Fishermen and Paddlers?

The native people of the arctic, who originally created the first kayaks were used to sit down on the floor with their legs stretched forward, and therefore didn’t have any use for additional support for their lumbar spine. This is why native kayaks did not feature a backrest, or any other ‘lumbar support’.
When Westerners began paddling those aboriginal kayaks they noticed they had problems staying upright with their legs stretched forward, in the posture known as the L position. This is because they were not used to sitting in this position in everyday life, and the muscles in their body weren’t adjusted to it. Rather than adjusting the paddler to the kayak, designers and manufacturers decided it would be easier to try and adapt the kayak to the paddler, and introduced a combination of backrest and footrests designed to lock the kayakers in the L position, and prevent their upper body from ‘falling’ backward or sliding forward (‘slouching’).
The kayak paddler, or fisherman is effectively ‘supported’ by three rigid points anchored in the kayak: two footrests and one back rest. By continuously pushing against those three points, the kayak fisherman’s legs provide the power necessary to maintain his body in its place, and in the required posture.

How Does the L Posture Affect the Lumbar Spine?

Your legs have the most powerful set of muscles in your body, capable of making you run, jump and kick. When you’re locked in the L position, your legs are constantly pushing against the kayak’s footrests, as well as against your lumbar spine, which is ‘supported’ by the backrest behind it.
This strong, continuous pressure on your lumbar spine comes from an unnatural angle, that is from the backrest behind it. There is no way for you to stop it or relieve it as long as you’re in this position, which is the only one that sit-in and sit-on-top (SOT) kayaks are designed to offer.
Effectively, when you’re paddling such kayak or fishing from it, the only way for you to relieve the pressure is to get out of the kayak, stand up and stretch, walk, etc.

How Does it Lead to Pain, and to the ‘Yak Back’ Syndrome?

Getting out of the kayak in order to relieve the pressure on your lower back is not a realistic option in most cases, and this is why most kayak fishermen and paddlers keep sitting in their kayaks although they feel a growing discomfort, and eventually pain in their backs.
This pain is known as ‘Yak Back’, and most people who paddle sit-in and SOT kayaks for periods longer than an hour experience it sooner or later, to some extent.
The pain is the result of the abnormal pressure on the cartilage rings, and the contraction of the the muscles in this area as a result of the effort they have to make in order to prevent back (spine) injuries, or at least minimize them.
Try to imagine the fight between the extremely powerful legs pushing your lumbar spine against the backrest behind you, and the much less powerful muscles in your lower back that are trying to protect your spine, and prevent it from being damaged.
Luckily for you, your lower back would soon enough start to ‘scream’ that it’s being hurt, or in other words – you’re going to feel pain. This pain should tell you to stop this unhealthy struggle between your legs and your back, before your back gets seriously injured.
Ignoring the pain at any given moment would result in the aggravation of the problem, that is to more pain, and eventually to a more severe back injury that would take you a longer time to recover from.

How much pressure do your legs exert on your lower back (lumbar spine) in the L position?

We’ve measured 40 to 60 lbs in adults.
You can try and measure the pressure yourself, using a bathroom scale positioned vertically between your lower back and your kayak backrest: Have someone stand behind you and read the dial for you.
It’s bad news for your lower back, considering the pressure is constant, and you can’t avoid it.
It’s even worse news considering the fact that effectively, this pressure is applied on a few lumbar vertebrae and cartilage discs that are badly positioned to resist it in such angle.
In terms of lbs per square inch, these pressure figures would be impressive, as well as most alarming.

Proper Paddling Technique, Cushioned Seats, and the Reality of Back Pain and Injury

Kayaking and kayak fishing instructors would tell you to sit straight in order to improve your kayaking technique and perform the required rotational movements of the torso in a more efficient manner. However, you need to remember that the people who initially invented and perfected this technique or paddling styles never used a backrest in their kayaks, because they didn’t need to. Consequently, they didn’t suffer from ‘Yak Back’ – unlike you.
This is to say that perfecting your kayaking technique would not improve your lower back’s situation in any way: You will keep feeling discomfort and pain, and you’ll keep being at risk of back injuries, and even chronic damage.
The obvious reason for this is the fact that your legs will keep pushing your lumbar spine against your kayak’s backrest.

Sit-in and SOT kayak vendors would offer you to ‘upgrade’ to the latest ‘ergonomic’ seat, that’s bound to more more expensive than the last one you bought. They would praise the extra cushioning offered to your hips and lower back, and claim that such seats would get rid of your fatigue, back pain and leg numbness – once and for all.
The reality is quite different: Special kayak seats have been around for decades, and none of them has produced the desired effect of ending the Yak Back, simply because all seats have a backrest by definition, and no amount of cushioning can reduce the total amount of force that your legs use when they push that backrest against your lumbar spine.
On the contrary: The extra soft cushioning may reduce the point pressure on softer tissues in your lower back (E.G. skin), and by that somehow delay the sensation of discomfort and eventually pain in your lumbar spine and in the muscles that support it. In other words, you’ll start feeling the problem when it’s already at a more advanced stage, which is not necessarily a good thing for you, if you think about it from your a health perspective.

Higher Seats

In recent years, manufacturers of fishing kayaks have attempted to address the back pain problem by offering bigger and wider kayaks a.k.a. ‘barges‘ outfitted with higher seats. Their rationale was “We’d better allow the user to sit higher, and we’ll compensate them for the lost stability by making their kayak wider and thus stabler”.
But does this approach work?  – Not really, since due to their mono-hull, elliptical form, increasing the width of sit-on-top (SOT) or sit-in kayaks (SIK) has a rather limited effect on itheir stability.  Therefore, their users (especially if they’re heavy people) must compensate for some of the lost stability by working harder with their legs, which in this case of SOTs and SIKs results in them applying more horizontal pressure on their lower back, which leads to discomfort, pain, and in some cases even injuries.

What Your Lumbar Spine Requires When You’re Kayak Fishing

Obviously, you need to avoid paddling and fishing in the L position, because it’s not merely uncomfortable, but in fact potentially harmful to your lower back, and sitting in it regularly for prolonged periods of time could lead to back injuries and chronic back pain.
Having said that, what would be the ideal fishing kayak for you? -One that would offer you comfort at all times, and the ability to take care of your sore back.
In fact, such kayak does exist. It’s the patented Wavewalk™ kayak, and by patent we mean a patent for an invention (utility patent), and not just a design patent.
To begin with, W fishing kayaks feature no backrest whatsoever – similarly to all-terrain vehicles (ATV), snowmobiles, off-road motorbikes, and jet-skis. What all of those have in common is the fact that when you ride them it’s your own legs that support your upper body. This is good news for your lumbar spine, since it’s basically a posture equivalent to walking, or running – since no unnatural pressure points are being created.
Second, the saddle type seat that W fishing kayaks feature offers a variety of positions, including standing up, plus the ability to change between any two positions at any given moment. Thus, whatever discomfort felt in your back, or local pressure building up in any part of your body can be effectively relieved as soon as you feel it.
As a result, even paddlers and fishermen suffering from chronic and acute back problems report spending long hours in their W kayaks without feeling discomfort or pain. You can find such testimonials in many W kayak reviews, where owners tell that without their W kayak, paddling or fishing from kayaks would be impossible for them – because of their back condition.
