The world’s fastest kayak is the Wavewalk S4, propelled by a 9.8 HP Tohatsu outboard motor. The S4 can go at a 17 mph speed (27 kmh) when propelled by a 9.8 HP motor, with only the driver on board.
What is the world’s speed record for kayaks?
The current kayak speed record is 17 mph (27 kmh). This speed record was achieved by Captain Larry Jarboe, in Key Largo, on January 17th, 2018, in a Wavewalk S4 outfitted with a 9.8 HP outboard motor.
What makes a kayak faster?
The factors that contribute to a kayak’s speed are its Size, Weight, Dimensions, and Propulsion. Human Powered: In a paddling or pedaling mode on flat water, mono-hull kayaks with a high Length to Beam (L/B) ratio, namely very long and narrow kayaks, are generally faster than kayaks with a low L/B, which are more stable. In choppy water, the kayak’s Stability and Balancing capabilities offered to its crew play a more important role. Motorized: At high speeds, such as when the kayak is motorized by a powerful outboard motor, Stability and Balancing capabilities are the dominant speed factors, as the kayak moves in a planing mode and no longer in a displacement mode – The stabler the kayak, the easier and safer it is for its driver to drive it at high speed. Additionally, kayaks that offer their driver to drive while seated closer to the motor are safer and easier to drive than kayaks that have the driver separated from the outboard motor by a longer distance.
Why is stability a key factor for speed?
Stability is defined as resistance to change. A kayak driven at high speed can flip over more easily than at a lower speed, and better lateral stability means that it can be driven at higher speeds with a lesser risk of overturning.
What is the most stable kayak?
The world’s most stable kayak is the Wavewalk S4. It is the only kayak that enables a 200 lbs full-size adult to stand on one side of the kayak with both feet, and turn around themselves as if they stood on the deck of a full-size boat. It is also the only kayak that can be driven at high speed in rough water, namely the most seaworthy kayak. This unmatched stability results from the fact that the S4 features a patented twin hull. In this full fledged, true catamaran form, the boat’s volume is distributed along its left and right sides, where it is the most effective in offering maximum buoyancy and therefore best support for the shifting weight of both passengers and gear. This optimal performance is in contrast to other kayaks that feature conventional mono-hulls, where the hull’s volume is concentrated along the boat’s center line in a way that makes it the least effective in stability terms.
Why is balancing capability a key factor for kayak speed?
Being a small vessel, a kayak is inherently less stable than bigger boats, and therefore the ability of the kayak’s user(s) to balance themselves and their kayak effectively is key factor in the kayak’s overall stability. Balancing capability is a key ergonomic factor for driving many types of small vehicles, both human powered and motorized. It is particularly important in bicycles and motorcycles that offer no stability of their own, and therefore depend entirely on their users’ ability to balance them. Other vehicles that offer their users good balancing capabilities are All-Terrain Vehicles (ATV), snowmobiles, and Personal Watercraft (PWC).
What gives a kayak user better balancing capabilities?
A type of seat known as a Saddle is what all the above listed vehicles have in common. A saddle allows the user to balance themselves with their legs straddling the seat, in a manner similar to horse riding. The user straddling the saddle seat can easily and swiftly shift their weight from one leg to another, in a way that resembles balancing while running and jumping, namely more naturally, intuitively, and effectively than when seated in other positions, such as on a bench, swivel seat, chair, or in the notoriously uncomfortable and unstable L kayaking position.
What makes the Wavewalk S4 faster than other kayaks?
The Wavewalk S4 is the world’s fastest motorized kayak due to the fact that it is the world’s most stable kayak. This urivaled stability is made possible thanks to its twin-hull (catamaran hulls) and the ability of its crew to balance themselves effectively while riding a saddle seat, similarly to the way that Personal Watercraft (PWC) and other high performance vehicles (e.g. motorcycles, ATVs, snowmobiles) balance themselves and their vehicles.

What are the advantages of a fast kayak?
The main advantages of a faster kayak is that it saves you time when you want to get somewhere, such as a productive fishery, and it makes it possible for you to access remote locations. In addition, speed is enjoyable, and driving a fast kayak is fun.
Practically speaking, a fast and stable kayak that’s also highly seaworthy presents the advantages of a microskiff (micro skiff), in addition to being a car-top boat, and the ability to carry it to and from the beach, without depending on boat ramps.
This is a video that shows people driving their S4 skiffs standing, riding the saddle seat, and sitting side-saddle, with and without a passenger on board, on flat water, in the chop, and in the ocean, in 2 ft waves. No problem whatsoever – Just fun, fun, fun!
Stability is non-issue in the S4 – It’s neither a problem in the physical sense, namely how the boat reacts to external forces, or in the ergonomic and psychological sense, namely balancing oneself as a driver or a passenger. Driving is easy and intuitive, with or without a tiller extension, and the boat does what you want it to do, and feels almost like an extension of yourself. Driving standing feels like skiing, except for the fact that you fully control both speed and direction. Unlike standing in a Jon boat or on the flat deck of a common skiff, you stand in the S4 with a foot at the bottom of each hull and the saddle serves you as extra support and balancing enabler. In this sense, it’s more like riding a big personal watercraft, a.k.a. jet-ski, waverunner, etc. A person who had never driven a boat before can drive an S4 standing within a short time on their first trip in it.
Many thanks to Captain Larry Jarboe, who made this possible and so enjoyable 🙂

Jack, a middle aged owner of a motorized S4 from Texas writes -“Love to jump the wakes of jet skis and other boats.” Anyone who owns a Wavewalk would immediately understand what Jack is talking about, and identify with him, but other kayakers, canoeists and people who fish out of Jon boats, dinghies and skiffs would probably raise an eyebrow when they read this sentence –
For people who go in small watercraft and fish from them, a wake is a series of fast moving waves created in the water by the passage of a fast motorboat, and it is a threat. Kayakers hate wakes, and canoeists dread them, because a wake hitting their unstable vessel on its broadside can capsize it. But even passengers on board bigger and most stable boats, such as dinghies, skiffs and Jon boats, are not big fan of wakes, to say the least, and they would not associate wakes with fun. Although wakes are typically not powerful enough to capsize a good size Jon boat or skiff, a wake suddenly hitting such a boat on its broadside is enough to destabilize passengers who stand in it, or on its deck, if they are unprepared for the sudden sideways tilt induced by the wake. And losing your balance in such a small boat can mean that you’d go overboard, or worse – capsize your boat, frequently as a result of your abrupt change in position causing another another passenger on board to lose their balance, in a chain reaction…
It is easy to destabilize a person standing on the deck of a Jon boat, or a skiff, but it is almost impossible to destabilize a person standing in a Wavewalk S4, with a leg in each hull. Why is that? It’s because a person standing this way in their S4 and momentarily losing their stability would simply drop on the S4’s saddle, to the lower Riding posture, which is the same position in which people driving a personal watercraft (a.k.a. “jet-ski”) drive their fast ride, or by extension, the same position offered by all-terrain vehicles (ATV) and snowmobiles.
All these vehicles, namely Wavewalks, PWC, ATV and snowmobiles are the most stable in their domains, and for their size, and they all offer similar saddle seats and riding postures to their users. There is no coincidence here, since the riding posture they offer is similar to the riding posture on horses and motorcycles, and it is naturally stable, namely that a person riding with a leg on each side of the saddle has the full ability to react intuitively, instantly, and most effectively to any change, and thus balance themselves in the most efficient way.
To put it clearly – a motorcycle is a vehicle with no stability it itself whatsoever. It you try to make a motorcycle stand without a person driving and balancing it, or without a mechanical support such as a metal leg or a wall, it would always fall on its side. But give that motorcycle a driver who rides its saddle, and it could go over the roughest terrain, and at high speed. This is to say that all the stability perceived in a moving motorcycle comes from its driver, and only from them, and it is the result of ability to balance themselves effectively while riding their vehicle’s saddle.
In comparison, a Wavewalk kayak offers the same balancing capability, plus its own stability as a twin-hull boat, namely a catamaran.
Tracking is the main problem that paddlers need to overcome when paddling in strong wind. Wavewalk paddlers usually report excellent performance of their boats under wind, since catamarans tracks well, generally, and also thanks to the fact that it offers multiple means for power-paddling, as well as for counter-affecting the wind. Since 2004, thousands of people have been paddling Wavewalk kayaks from the 300, 500 and 700 series, and none of these paddlers outfitted their Wavewalk with a rudder – that cumbersome device that has become an integral part of all other types of high-end kayaks used for touring and fishing.
Here are some tips that can improve your Wavewalk kayak’s performance when you’re paddling in strong wind:
1. Paddle only in the Riding Position, which is the optimal posture for power and balancing, and lean a bit forward, with your knees lower than your hips – That would give you extra power.
2. Paddle from the middle of the cockpit, as much as possible –
If you paddle from its rear it would raise your W kayak’s bow and expose it to the wind, and the boat will turn away from the wind.
If you paddle from the front of the cockpit, the stern will go up, and the kayak will turn into the wind.
3. Lean your W kayak into the wind – That would make it harder for it to affect the course of your W kayak.
4. Apply short J strokes on the side from which the wind is blowing, and more powerful strokes on the lee side (the sheltered side) – That would help you track. You may even hold the paddle not from its middle, so that you can apply longer strokes on the lee side.
6. Any object protruding from the deck is exposed to the wind, and therefore generates additional drag – Detach the spray shield if you have one attached, dismount deck mounted rod holders, and store your fishing rods inside the hulls whenever possible. A milk crate would act as a small sail that’s controlled by the wind, so you’d better avoid using one altogether.
7. Keep paddling in a steady pace and a straight course – This is not about one-time corrections, but about minimizing your effort and getting there. Precision and efficiency are as important as power.
8. IMPORTANT – Remember that you can easily move fore and aft along the Wavewalk’s saddle, and by doing so control the angle in which your W kayak will point relatively to the direction from which the wind blows: Paddling from a forward position will tend to point the kayak’s bow into the wind, and paddling from a backward position will tend to point the bow away from the wind. By applying small changes to your own location on the saddle, you can minimize the wind’s unwanted effect on your Wavewalk, and keep it tracking with little effort.
Biomechanical and Ergonomic Solutions in Kayak Design – Kayaking With No Back Pain
Back problems are the number one source of disability in the United States, and one of the main reasons why many people do not engage in kayaking and kayak fishing, or drop out from these activities after they realize that they cannot enjoy them.
This article defines the causes of back pain and discomfort that most people feel when paddling kayaks and fishing from them. It also explains how Wavewalk’s patented invention solves these problems, and why people who paddle these kayaks and fish out of them feel neither back pain nor any other discomfort after long hours, including people with various disabilities, back problems and excess weight, as well as elderly people.
Have you ever fished out of a kayak? If you did, you’ve probably noticed that something is wrong… Simply put, you weren’t feeling comfortable, and you may even experienced pain in your back and legs, and after some time, all you could wish for was to get out of that kayak as soon as possible, even if the fish were biting…
The problem you’ve experienced is simple, and sooner or later anyone who paddles kayaks and fishes from them faces it: Spending long hours paddling and fishing in or on top of an ordinary kayak, whether it’s a sit-in, hybrid or sit-on-top (SOT) inevitably causes some circulation problems and leg numbness, occasional cramps, pain in your lower back, and often fatigue and discomfort in your shoulders and neck. In fact, kayaking is so closely associated with back pain that kayakers commonly appear in TV ads for back painkillers and pain relief patches.
After you begin seeking information about your problem and advice on ways to solve it, you realize that the only thing that really works is paddling back to shore, standing up, and performing the exercises that physiotherapists recommend for kayakers. In other words, there is no gear that you can outfit your ordinary kayak with that can provide an effective and long lasting solution to any of these symptoms, because they occur as a result of you being seated in the L position – the traditional sitting position in kayaks, with your legs stretched in front of you while pushing your back against your seat’s backrest.
2. What Causes this Problem?
Being Seated In The Traditional, L Kayaking Position
The problem is caused by a combination of two things:
1. Being seated in a non ergonomic position to start with, and 2. Being unable to switch to other positions and release the stress that builds up in the critical pressure points in your body, especially in your legs and lower back.
Have you ever asked yourself why is it that the traditional, L kayaking position is used only in ordinary kayaks and in no other land, snow or water equipment? The answer is that it’s because although the L position is the worst for you it’s simply the only one that ordinary kayaks can offer.
Double Trouble: The Combined Effect of Horizontal and Vertical Pressure on Your Lower Back:
Figure 1. Horizontal Pressure
Figure 1 on the left shows the horizontal pressure that your legs exert on your lower back in the traditional L position used in all ordinary kayaks including both sit-in (SIK) and sit-on-top (SOT).
The pressure points in the lower back region can cause irritation and inflammation of the sciatic nerve (sciatica) felt as pain traveling from the lower region of your back down across your lower thigh. Foot braces and other support for your feet actually increase the horizontal pressure that your legs exert on your lower back. The back support and foot braces may hold you in your torso in place and prevent you from falling backwards or slipping downward, but they also limit your freedom of movement, increase pressure on your lower back, cause leg numbness and cramps and result in increased fatigue.
Native people of the Arctic circle who were the first to make and paddle kayaks used neither back rests nor foot braces simply because they were accustomed since infancy to sitting on the floor with their legs stretched forward, unlike us modern Westerners who lose this ability in early childhood when we learn to sit on chairs.
Figure 2. Vertical Pressure (Weight)
Figure 2 on the left shows the heavy vertical pressure (weight) applied on the lower part of your spine when you’re seated in the traditional L kayaking position.
The same sensitive area in your spine that’s pressurized horizontally by your legs pushing on it is being pressurized even more by the combined weight of your torso and thighs, that is nearly all your body weight. Your legs are prevented from supporting your body weight in this position.
In addition, sitting in the L position without being able to change your body position increases your fatigue and discomfort, and reduces both performance and fun. Cushioning your seat doesn’t really solve any of these problems since all it can do is spread the pressure from a single point to a wider area, but the combined pressure is still there and it keeps working on your lower back all the time. Sooner or later you feel very uncomfortable, and sometime it’s too late since you’ve already been injured. Kayaking in the L position with no adequate support for either back or feet is not a sensible solution for modern anglers and paddlers who have to spend hours kayaking and fishing from this low and uncomfortable position.
Food for thought:
If you had to perform some hard work or other physical activity in any position of your choice, would you even consider doing it sitting with your legs stretched forward like this? Do you fish or do you know anybody who fishes seated in this position from shore or from any other type of fishing boat? -The answer is: No.
More food for thought:
Airplane coach seats are fairly comfortable – certainly more than regular kayak seats, but why is it that after some time most people feel uneasy sitting in them? The answer is that the limited space makes it difficult for you to change positions, which leads to the buildup of discomfort and fatigue to a point where many people feel they must stand up and stretch, and those who can afford it promise themselves to fly first class next time – if only for the extra legroom.
Not all damages are felt immediately. Sometimes it takes years for the damage to accumulate, and by then it might be too late to fix it. This is true for back and shoulder problems.
What do cross-country motorbikes, mountain bikes, horses, snowmobiles, all-terrain vehicles (ATV) and personal watercraft (PWC) have in common? It’s the fact that their user operates them in the Riding Position. And what do skiing, surfing, water skiing, dog sledding, snowboarding, windsurfing, skating and skateboarding have in common? -The Standing Position. This is simply because the Riding and Standing positions are the best for you in both ergonomic and biomechanic terms, which means they offer best control and more power, and result in less fatigue and injuries. When we need to make long efforts during motion we have more available power and better control standing or sitting with our legs lower than our upper body (biomechanical advantage), and we also feel more comfortable and less tired this way (ergonomic advantage).
4. Engineering the Optimal Solution
Freedom to Choose = Less Fatigue = Enhanced Comfort = More Fun + Healthier Paddling and Fishing
Only the W kayak solution departs radically from the L position and offers a new, comprehensive and effective approach to all ergonomic and biomechanical issues in paddling and paddle fishing. The new, patented W Kayak re-distributes buoyancy from the boat’s longitudinal axis all the way to its two sides, and thus offers maximal support to the user’s balancing, control, steering, propulsion and fishing efforts. The central part of the W Kayak, its ‘backbone’, which joins the two hulls, is shaped like a long, 14″ high saddle. W kayakers can move back and forth along the saddle, according to their need (e.g. tandem, surfing, paddling in strong wind, launching, etc.). They can also switch anytime between numerous ergonomic positions, as shown below:
5. Riding (Mounted)
The Natural Position
Riding is the most stable, comfortable and powerful paddling position, and it offers best control over your boat and the most leverage on your paddle. In the Riding position your thighs, legs and feet are positioned directly below your body and take active part in all your efforts: Balancing, Control and Paddling. Riding is the best position for beginning W Kayakers. It is also the best position in whitewater and surfing applications.
Note that your legs support your upper body from both sides, and your feet are in a direct vertical line below your body.
For Fishing: Riding is the preferred position, rivaling only with standing. When you cast riding you have more power than when casting in the sitting position. Riding a W Kayak is similar to mounting a pony: Your upper body rests on the saddle and your thighs hold its sides, while each foot rests firmly on the bottom of a hull, as it would in a stirrup. This position is similar to the riding position used in other high performance vehicles such All Terrain Vehicles (ATV), Snowmobiles, and Jet Skis.
Watch this slow-motion demo video of the Riding position:
Sitting means having your legs positioned in front of your body.
Sitting positions are less stable and powerful than Riding, and not recommended for beginning W Kayakers, or for paddling in moving water. The sitting positions are good for relaxing on flat water.
Adding a back rest (lumbar support) is not necessary in the W kayak, and few W kayakers choose to outfit their boat with such an accessory.
1. Regular sitting, which is similar to sitting in a canoe 2. Sitting with both legs stretched forward 3. Mixed: one leg in the regular position and the other stretched forward
The Stand Up Kayak – For Real
Unfortunately, stand up paddling is often described as a feature offered by many kayaks and stand up paddle boards out there, but nothing could be further from the truth – In fact, when it comes to normal paddlers and anglers, who are neither lightweight nor extremely athletic, only W kayaks offer the possibility to paddle and fish standing up in comfort and confidence, and only W kayaks offer a critical safety feature in the form of a 14″ high saddle to fall on, in case you lose balance.
You can paddle on both sides of the boat or just on one side- in parallel and with a J stroke.
After some practicing you can try to paddle standing in moving water and in the surf.
6. Super Stability
Stability is key to comfort and good ergonomics. The patented W Kayak offers unmatched stability trough a unique combination of three factors:
The boat’s buoyancy is sensibly distributed along its sides, instead of being wasted along its central, longitudinal axis.
The passengers make natural use of their legs and feet to balance themselves by shifting their weight sideways, from one leg to another, and they apply this weight directly to the bottom of the hulls – below waterline, thus creating an effect of ‘dynamic ballast’.
The immersed profiles of the boat’s twin hulls act as multiple ‘Hard Chines’, thus offering maximal lateral resistance, and unmatched initial (primary) stability.
The W Kayak offers you the ability to throw to longer distances, which presents two advantages:
1. Being able to cover more water from a stationary position before you need to move your kayak 2. Some fish species can sense the presence of your kayak nearby and therefore are better caught from a distance.
When fighting powerful fish you want to be in full control of your kayak, and the W kayak offers you all the means for it. Read More »
8. The Cockpit – A Place To Be In, And Work In
Your kayak’s cockpit has other functions besides protecting you and offering you optimal comfort. It is also a workplace in which you store your gear and handle it. In W kayaks all the gear you need is within arm’s reach, and there’s no chance of it going overboard since in case it slips out of your hand it would end at the bottom of one of the hulls, where it’s easy for you to find and reach it.
Can I outfit the W kayak cockpit with a seat on top of its saddle?
Most W kayakers don’t add anything to their W kayak’s saddle, because they find it perfectly comfortable. Some people cover the saddle with a blanket or a thin foam mattress. Adding a kayak seat to the W kayak saddle is easy, but virtually no one does it. We know of a couple W anglers who outfitted their W kayaks with lightweight swivel chairs, and a couple more who added a DIY reclining back rest because of scoliosis problems. In fact, you can simply drop a plastic chair or a lawn chair in the cockpit, as seen here in this image, but hardly no one does it, simply because the W saddle offers the best comfort.
