“Kayak”??… This is likely to be the last thing that comes to mind of anyone watching this movie, but indeed, the S4, like all Wavewalk’s patented catamaran boats, is officially designated as a kayak, not just because of its light weight (98 lbs) and high performance as a paddle craft, but mainly thanks to certain design features required by law. Skiff?… The kind of performance seen in this movie is not what you’d expect from a skiff or skiff by name. Wavewalk likes to bring forward the S4’s performance as a skiff, namely a fishing boat for flat water, but there’s no flat water to be seen in this offshore movie… far from that! PWC?… Such comparison would have been more appropriate if we used wheel steering instead of direct steering with the tiller, and possibly an even more powerful motor than the 9.8 HP Tohatsu that features in this movie. Nevertheless, the movie conveys some of the action and excitement associated with Personal Watercraft (PWC), sometimes referred to as jet-skis.
PWC stability at high speed
This video shows the Wavewalk S4 powered by a 9.8 HP Tohatsu outboard motor, driven at full throttle, offshore, in choppy water and waves. It demonstrates a performance level that’s new in the world of small boats and watercraft, including both unrivaled speed and stability that enables stand-up driving and wave-hopping that one expects to find only in Personal Watercraft (PWC).
Perfect balancing and ergonomic saddle seat
The Wavewalk design and PWC have one feature in common, which is their similar saddle seats that deliver the best balancing capabilities to the driver and passengers. But the advantage of the saddle seat doesn’t end there – The saddle also allows the driver and passengers’ legs to act naturally as powerful and effective shock absorbers that protect their backs from the unwanted impact of the constant leaps and bounds, and high speed clashes with waves.
Being officially designated as a kayak, the S4 delivers these capabilities in a paddling mode too, although at much lower speeds…
A most seaworthy small boat
The performance seen in this video is not the kind of performance that flat-bottomed boats such as Jon boats or skiffs can deliver. The S4 is seaworthy, while these traditional small fishing boats aren’t. What cannot be well perceived from watching this movie is the fact that the S4 is dry too – Frontal clashes with waves do not let water into its hulls, and the only time when spray gets in is when the boat is hits a wave with its broadside. Even then, very little water gets inside.
Shooting this video
The cameraman was Captain Larry Jarboe, standing on the deck of his fishing boat, the Line Dancer, that was anchored in the same choppy waters as the S4 is seen going in. The Line Dancer was constantly bouncing and tilting, which made it particularly difficult to shoot video of another, distant and fast moving small boat. Larry used a Nikon Coolpix 900 digital camera with a powerful x83 optical zoom lens, in an auto-focus mode, but since placing this camera on a tripod would have been useless under these hectic conditions, Larry’s sea legs were the decisive factor that helped produce the video footage for this movie.
The White Knight – Larry’s workhorse S4
The boat in this movie is Larry’s personal S4, dubbed the White Knight. Larry offers fishing and diving tours in Key Largo, and it is this boat that he uses in these trips, and on a daily basis. The White Knight features a base for a diving ladder at the bow, and foam boards on its sides, since Larry sometimes uses it to side-tow two other S4s,each attached to a different side of the White Knight.
The White Knight is powered by a 9.8 HP 2-cycle Tohatsu outboard motor, and Larry recently clocked 17 mph with it, which is a world speed record for kayaks.
Driving the S4
The S4 operator in this movie is 56 years old, and not in great shape. An athletic driver half his age would have probably driven the S4 more aggressively and spectacularly, but that tired-looking, gray haired driver adds a feeling of reality to the video, or so we hope…
Portable boats have been around for decades, and over time, they have gained many fans, as well as opponents. This article is an attempt to shed more light on this subject, clarify the basic things that are worth knowing, determine factors that should be given consideration when deciding whether to buy a portable boat or not, and which type, as well as offer information on the latest developments in this field. Special attention is given to Wavewalk’s Series 4 (S4), a new type of portable boat based on the company’s patented invention. The S4 is good new for those who are looking to get a high performance car-top boat without compromising on stability, comfort and dryness.
The following playlist includes YouTube videos showing the S4 used in different applications and environments, and by different people. One of the videos shows a user uploading an S4 on top of his SUV in under thirty seconds –

Portable boat – Definition
A portable boat is a small boat that’s lightweight enough for a person to upload onto their vehicle’s roof rack in order to transport it this way. A portable boat must also be lightweight enough for one person to carry by hand from their vehicle to the water, and back. In other words, a portable boat is a car-top boat, and vice versa. This is to say that portable boats do not require transportation by trailer. But not all trailer-free boats offer the same degree of portability, and some small dinghies, Jon boats and motorized boards may be hauled onto a pickup truck bed, but still be too heavy and bulky for either car topping or easy carrying. Therefore, these small boat are not true portable boats.
Are kayaks portable boats?
Kayaks are not considered to be portable boats despite their being small and typically lightweight enough to be car topped and carried by hand. This is because kayaks don’t lend themselves to effective motorizing, and the same is true for canoes, with the exception for square-stern canoes designed to accommodate a small outboard motor, and be driven on flat water. Kayaks with built-in electric trolling motors are not portable boats either, since their motors are extremely weak in comparison to the smallest portable outboard gas engines that power boats. Only a vessel that is both a boat in the full sense of functionality and comfort expected from a motorboat, as well fully portable, may qualify as a portable boat.
Are motorized boards portable boats?
Motorized boards are vessels that offer neither minimal free board nor sufficient load capacity to count as boats. Ironically, some of them are too heavy to be car-topped, which is yet another reason why they may not count as portable boats.
Portability is key
Portability can save you both time and money. In dollar terms, portability saves you the money that you would have spent on a boat trailer. It’s always good to have a few extra dollars to spend on the boat itself, or on fishing gear. However, what’s more important is the fact that a portable boat saves you time that you can spent having fun on the water, instead of on the road, driving to or from a boat ramp, as boat ramps are the only places that allow you to launch a boat from a trailer. By the same token, a portable boat saves you waiting time at the boat ramp, waiting for other boat owners to launch their boats, or take them out before you could do it with your own boat. Owning a car-top boat guarantees that you’d never arrive to a boat ramp just to find that the facility had run out of parking space for your vehicle and your boat trailer. Simply put, portability frees you to launch anywhere you want, and in the case of the S4, even in rocky beaches a.k.a. “Rock Gardens”, as seen in one of the videos featuring in the above playlist.
Portable boats include dinghies, Jon boats and square-stern canoes that are small and lightweight enough for car topping. Typically, such boats are made from aluminum (welded or riveted), fiberglass, or plastic resin such as Polyethylene (PE). A rigid hull offers the advantage of being ready to go on water without spending time and energy on inflating and assembly. As soon as they are out of the water, rigid-hull portable boats (RIB) cannot be car-topped without deflating or disassembling them. One of the drawbacks of a car-topped boat compared to a boat transported on a trailer is that with a car-top boat, you have to mount the outboard motor on the boat before you launch, and dismount it at the end of the trip, so you could transport it inside your vehicle. This said, an experienced boat owner can mount and dismount a small, namely portable outboard motor within a couple of minutes.
A folding hull is made from rigid panels attached by flexible sections. Folding a boat makes it take less space, and being less bulky can be an advantage for transportation. Upon arrival to the launching spot, a folding hull needs to be unfolded, and the boat requires assembly for its seats, transom, etc., which can take up to twenty minutes. Disassembling the boat and folding it back can take a similar time, and altogether, whatever time is gained as a result of not having to launch at a boat ramp thanks to the lack of a trailer, might be wasted on tedious assembly and disassembly work.
Inflatable Boat and Inflatable Pontoons
Inflatable dinghies are made from soft parts, and rigid inflatable boats (RIB) have rigid parts too, which require both assembly and inflation before launching, and disassembly as well as deflation and folding at the end of the trip. These extra activities can take considerable time, even for an experienced user with a good electric pump. Generally speaking, anglers typically prefer not to fish out of inflatable boats because of the risk of a fishing hook or a knife perforating the hull.
Some small catamarans may be transported on top of a vehicle. These boats feature closed rigid hulls namely pontoons, and their decks are made from sections that can be assembled for boating, and disassembled to allow transportation on a vehicle. Typically, these are sailing catamarans, and they are rarely used for fishing.
Stability, Comfort, and Seaworthiness problems in portable boats
The need to compact the boat so it could be car-topped leads to some portable boat designs lacking in seaworthiness, stability, and comfort. Canoes feature either round bottomed or flat bottomed hulls. The first is extremely tippy and prone to rolling, especially for a crew of more than one, and the latter is stabler on flat water, but insufficiently stable in choppy water, and in the presence of powerboats’ wakes. Jon boats, aluminum dinghies and micro skiffs that feature a flat bottom hull are moderately stable on flat water, especially if they are very wide, but they lack the stability required for driving and fishing in moving water. Jon boats, dinghies and skiffs with a shallow V hull are more stable in moving water, but less stable on flat water. Inflatable dinghies are very wide, and they are designed to allow driving in moving water, but these boats are not comfortable.
Small, compact boats are not the most comfortable, with the exception of the S4, which features a large-size saddle resembling the saddle seats found in bigger personal watercraft (PWC) sometimes called jet-skis. The S4’s saddle combined its twin-hull design delivers the highest performance in terms of balancing, namely the users’ ability to react instantly, intuitively and effortlessly to changes, as well as actively balance the boat. The S4’s stability combined with the effective balancing capabilities it offers to its users contribute to its exceptional seaworthiness.
Which car-top boat is the most portable?
A boat’s portability is affected mainly by its weight. The S4 weighs a little less than 100 lbs without a motor, and this makes it the lightest boat relatively to its load capacity of over 600 lbs. The S4 also features a fully rigid twin-hull that requires no time-consuming inflation or assembly. Therefore, it is fair to say that the S4 is the world’s most portable boat.
Which portable boat is the most stable?
The Wavewalk S4 is the world’s most stable in its category of portable boats that require neither inflation nor assembly. With its load capacity of over 600 lbs and its saddle seat, this patented boat can carry up to three adult passengers on board, and they may all stand up at the same time –
Which portable boat is the most seaworthy?
This question is more difficult to answer, since many inflatable and rigid-inflatable dinghies are very wide and designed to go in rough water. However, for a rigid hull portable boat, the Wavewalk S4 is the most seaworthy, since it can go in the ocean in waves up to 5 ft, and its driver can drive it in waves while they stand.
What is the most comfortable portable boat?
Portable boats usually come with simple bench-like seats, or basic swivel seats. Inflatable dinghies offer the driver and sometimes the passengers to sit on its inflatable chambers, or pontoons. Such seating accommodations are not ergonomically designed, which is why they are rather uncomfortable. On top of this, such crude seats do not provide boaters with effective means to o balance themselves, and this balancing deficiency becomes a severe comfort problem in rough water, as well as on longer trips. The Wavewalk S4 is the only portable boat that features an ergonomically designed PWC saddle-seat. These seats prevent back pain and they offer their users means for quick and efficient reaction to change, as well as easy, natural, intuitive, and highly effective balancing, including whilr going in rough water. S4 driver and passengers can face forward while they ride (straddle) the saddle with a foot in each hull, and they can also face sideways while sitting side-saddle with both feet in one hull. This works not just for small size people as well as for big and heavy guys. The above video playlist includes a movie showing an angler who weighs 330 lbs enjoying driving an S4 and fishing from it while seated side-saddle.
Which portable boat is the most versatile?
The Wavewalk S4 is hands down the most versatile portable boat, due to multiple reasons. These include the fact that the S4 works perfectly as a paddle craft both in a canoeing and kayaking mode. This excellent performance in a human powered mode is unique among motorboats, and it is important not just as an alternative for motorizing in case of emergency, such as engine problems, getting stranded at low tide, etc., but also for going in extremely shallow water (skinny water) where even small and lightweight boats draft too much. This is to say that the S4 is unbeatable as far as mobility is concerned. The S4 also works both in a solo and tandem mode with up to three adult passengers, and it features a frontal casting deck, as skiffs do. The S4’s seaworthiness is so good that it can serve as a fun boat for playing in waves. The S4 can also be easily towed by a bigger boat or hauled on board, and together with its generous load capacity, these attributes turn it into a most effective boat tender for yachts and big boats.
The following images offer a quick, condensed glimpse into various aspects of the S4, both as a car-top motorboat and a paddle craft, for leisure and fishing. For a better insight on the S4’s capabilities watch movies in the above playlist.
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.
My friend David Hernandez took another fisherman on board this Wavewalk 700. He was driving the boat standing up, and after a flawless turn he came back, and that’s when the other guy decided to stand up and keep fishing standing. This boat is so stable that none of them experienced any problem.
Wavewalk Kayak testing. These kayaks are awesome! Nearly impossible to sink. They are stable enough to stand up in and move around. They work great for fishing in remote areas and also work for waterfowl hunting in marshes that are tough to get to. There are endless modifications that can be made to make these kayaks fit nearly any need.
