KAYAKS DESIGNED TO PERFORM BETTER IN A BROADER RANGE OF CONDITIONS AND APPLICATIONS
21 miles in a kayak is a long distance, especially on lake Tahoe, which is often windy due to its 6,000 ft elevation. Anyone who wants to try paddling such a distance on that lake should choose their kayak carefully. Most paddlers capable of such a feat would opt for an extra-long and extra-narrow sit-in touring kayak, a.k.a. sea-kayak, outfitted with a rudder system, without which tracking would be hard, and maybe even impossible.
But Edwin Warner simply took his Wavewalk 700 twin-hull kayak to lake Tahoe, and crossed it from its west shore to its east shore and back in 5.5 hours. Edwin weighs about 250 lbs, and he’s not a racing kayaker. In fact, he is a kayak fisherman, whose preferred activity is crabbing in the San Francisco bay. Edwin didn’t even consider outfitting his W700 with a rudder, and no Wavewalk paddler ever did such a thing, since it’s totally unnecessary, because Wavewalk kayaks track well naturally, due to the fact that they are catamarans, and their users can relocate their center of gravity (CG) fore and aft, and thus effectively control the way the kayak reacts to wind coming from any direction, and neutralize this unwanted factor.
It didn’t occur to Edwin that fishing kayaks are not meant to go over such distances, since typically, they are sluggish and hard to paddle, and he didn’t stop to think that maybe tandem kayak with a load capacity of over 500 lbs is not exactly the optimal vessel for crossing such distances in windy conditions.
Edwin simply trusted his W700, because he’s been fishing with it in the Pacific ocean for years. He didn’t bother to get an extra-lightweight carbon-fiber paddle for this trip, because he knew that his sturdy Wavewalk paddle fits his W700, and he trusted it.
Edwin paddled this 21 mile distance in 5.5 hours, that is close to 3.82 mph in average – Not a bad time for a heavy, middle aged guy in a fishing kayak that’s less than 13 ft long. If Edwin had paddled this distance in a traditional 20 ft extra-long racing or touring kayak, his bad back would have forced him to turn around and cut his trip short.
So how is this story relevant to kayak design? It’s about the envelope of performance of the patented twin-hull kayaks made by Wavewalk – A single Wavewalk kayak can serve two large-size anglers or hunters in a long trip, where both will be seated or standing at will. They’d be able to carry on board all the gear they would need for such a trip, and progress at a good pace. And if needed, they could easily outfit their W700 with an outboard motor, and drive anywhere they want, regardless of winds and currents.
How do common mono-hull sit-in and sit-on-top (SOT) kayaks compare to this? Well, they don’t, really, since they under-perform the W700 in almost everything.
I sum, not all kayaks are equal, and Wavewalk’s patented kayaks outperform traditional, common sit-in and SOT kayaks.
A portable boat is a small, lightweight boat that can be easily transported on the roof of a common passenger vehicle, and carried by hand to the water and back from it by one or two persons. Portable boats are also referred to as car-top boats.
By definition, a portable boat does not require a trailer for transportation.
But when portability is concerned, not all trailer-free boats are equal, and some boats (e.g. small dinghies and Jon boats) and motorized boards are small and lightweight enough to be hauled onto a pickup truck bed, but too heavy and bulky for car topping and easy carrying, which is why these vessels are not considered as portable boats.
Kayaks are small vessels that are typically lightweight enough to be car topped and carried by hand, but since kayaks don’t lend themselves to effective motorizing, they are not considered as boats, and the same is true for most canoes, with the exception of very wide, square-stern canoes that can be driven on flat water with a small outboard gas motor.
Kayaks equipped with electric trolling motors are still considered to be kayaks and not portable boats, similarly to bicycles that are not designated as motorcycles even when outfitted with small motors.
A motorized board labeled as a skiff for a solo user would not qualify as a portable boat even if in the future a lightweight enough version of it is produced, because it lacks the load capacity and free board that are expected from a boat – even a small one.
In sum, in order for a vessel to qualify as a portable boat, if must be both a fully functional boat and fully portable.
Why is portability important?
Portability has advantages both in economic and time terms.
In dollar terms, portability offers you to save the money that you would have had to spend on a boat trailer, and spend it on the boat itself, and on other useful equipment such as electronics, fishing gear, etc.
More importantly, a portable boat makes you gain productive, fun time on the water that you would have otherwise spent driving to or from a boat ramp, which is the only place where you can launch a boat from a trailer. A portable boat also saves you time waiting at a boat ramp to launch your boat, and waiting for others to launch their boats or take them out before you can take out your own boat. Not having to depend on boat ramps guarantees that you’d never drive to a boat ramp just to find that there’s no more parking space left there for your vehicle and trailer.
At its highest level, portability gives you the freedom to launch anywhere you want, as seen in this video –
Types of portable boats
Some dinghies, Jon boats and square-stern canoes are small and lightweight enough to be car topped. They are made from aluminum, fiber reinforced plastic (FRP) – typically fiberglass, or polymer resin (plastic) such as Polyethylene.
Having a rigid hull means that these boats are ready to be driven without additional work such as inflating and/or assembly, and once the trip is over, they can be car-topped without deflating and/or disassembly.
The only difference between a car-top boat and a boat transported on a trailer is that a car-top boat requires mounting the outboard motor on it before launching, and dismounting it after the end of the trip. For an experienced boater, mounting the motor and dismounting it takes 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.
Some inflatable dinghies are made solely from soft parts, and others, namely rigid-inflatable boats, or RIB, include rigid components as well. This requires inflation and assembly before launching, and disassembly plus folding upon return from the trip. These activities take time, even if you’re experienced and equipped with a good electric pump.
Inflatable boats are not very popular among anglers, who prefer to avoid fishing from a boat whose hull might be perforated by a fishing hook, a knife, or other sharp object that anglers typically carry on board.
Some small catamarans feature rigid hulls (pontoons, actually), and they can be disassembled and transported in sections, on top of a car roof. Typically, such catamarans are used for sailing, and they are rarely used for fishing and hunting.
Other issues with portable boats
Aside from the problems that some portable boats present as far as assembly and disassembly time is concerned, some designs leave much to be desired in terms of seaworthiness, stability, and comfort –
Canoes are either round bottomed or flat bottomed. The first type of hull is extremely tippy, especially for a crew of more than one passenger, while the second type is moderately stable on flat water, and unstable on moving water.
Portable Jon boats and rigid dinghies that feature a flat bottom are moderately stable on flat water, but not stable enough for trips or fishing in moving water, or in the presence of wakes from big motorboats.
Portable Jon boats and dinghies that feature a shallow V hull perform better in moving water, but less so on flat water.
Portable Inflatable dinghies are very wide, and designed to go in moving water, but these boats are not comfortable.
What is the most portable boat?
At slightly less than 100 lbs, the Wavewalk S4 is the world’s most lightweight boat for a crew of more than two adult passengers, and it also features a fully rigid twin-hull that requires neither inflation nor assembly. These two facts combined make the S4 the world’s most portable boat.
What is the most stable portable boat?
For a boat that requires neither inflation nor assembly, the Wavewalk S4 is the world’s most stable in its class. With a load capacity of over 600 lbs and a saddle seat that’s similar to the seat of large-size high performance personal watercraft (PWC), this patented boat can carry up to three adult passengers on board – all of them standing up.
What is the most seaworthy portable boat?
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.
What is the most comfortable portable boat?
Typically, portable boats feature simple bench-like seats, or basic swivel seats. None of these seating accommodations is particularly comfortable, and they don’t offer good means for a user to balance themselves.
In contrast, the Wavewalk S4 features a saddle seat that prevents back pain, and allows for easy, natural, intuitive, and fully effective balancing, even in rough water. Both the driver and passengers of the S4 can ride (straddle) the saddle while facing forward, or sit side-saddle while facing sideways. This is true even for a big and heavy person who weighs more than 300 lbs.
What is the most versatile portable boat?
Hands down, the most versatile portable boat is the Wavewalk S4, since it works perfectly in a non-motorized mode, both with canoe and kayak paddles, in a solo and tandem mode, and it features a frontal casting deck, as skiffs do.
Being most seaworthy, the S4 can serve as a perfect tender for a yacht or a big motorboat, and it can be effectively towed behind the mother ship, as well as hauled on board.
This article examines different modes of propulsion available for kayaks today, and discusses their relative advantages and shortcomings.
Different modes of propulsion
Kayaks can be propelled by various means, which include paddling, pedaling, and motorizing*
Most people paddle their kayaks with dual blade (kayak) paddles, and rarely with single-blade (canoe) paddles.
Most pedal drive manufacturers today offer kayaks equipped with rotational drives (rotational pedals and rotational propeller), and one kayak manufacturer offers a pedal drive with push pedals and flapping blades.
Motors for kayaks range from weak electric motors (trolling motors) to powerful outboard gas engines (outboard motors).
This is the name given to paddling while an electric motor is working to provide extra power and increase the kayak’s range of travel. Assisted paddling is becoming increasingly popular, especially among kayak anglers whose fishing kayaks are typically not easily to paddle, and are often loaded with heavy fishing gear.
Assisted paddling is particularly useful in moving water (rivers, tidal currents), as well as in big lakes and the ocean.
This hybrid mode of propulsion is particularly useful for paddlers who aren’t necessarily in top physical condition due to weight, age, and physical disabilities.
For a couple of decades, the niche market for pedal driven kayaks had been dominated by push pedal drives, but it the last few years rotational pedal drives have become increasingly popular in this market, as numerous kayak manufacturers (especially fishing kayaks) started offering kayaks equipped with such drives. This transition is due to the fact that rotational pedal drives for kayaks are more efficient than push pedal ones.
It’s worth remembering that operating pedal driven kayaks is limited to water that’s neither shallow nor rich in vegetation, and a pedal dive won’t get you where a paddle could, which is why pedal kayak users always carry a paddle on board.
From an ergonomic standpoint, the effect of operating a pedal drive is even worse on a person’s back than the effect of paddling a SOT or sit-in kayak, because the continuous horizontal pressure that their legs exert on their lower back while pushing it against the seat’s backrest is bigger than the pressure exerted in a paddling mode in the L position.
Paddling in the common L kayaking position works for younger people who happen to be physically fit. Such people rarely suffer from back problems, which are the number one cause of disability in America.
For all other people, namely middle aged and elderly, and/or people who are overweight and not in top shape, paddling in the L position is a source of discomfort, pain, and even injuries, hence the expression “yak back”.
Since so many people in America suffer from a sensitive back or from more serious back problems, many anglers view kayaks as uncomfortable boats to fish from, and for a good reason, unless one considers Wavewalk’s patented kayaks, which are back pain free.
Electric motors are weak, which is why they’re often called trolling motors, namely motors for slow motion.
Having a motor on board is a good thing, as it adds safety in adverse conditions such as wind and current, or paddler fatigue, and it adds to the kayak’s range of travel. However, electric motors fail to deliver the performance that outboard gas engines offer when it comes to power, speed, and long trips.
There are two types of electric motors – Integrated (built-in) motors, and add-on motors that the user attaches to their kayak.
Ironically, the motors purchased separately from the kayak work better than the ones that come already installed in it. The reason for this absurd situation is that it’s easier to mount an electric motor on a kayak in a way that would effectively protect it in case it bumps against the bottom, while integrated motors have no effective protection for such cases. Since every body of water has a bottom, and the distance between the bottom and the surface is not always perceptible or predictable, such unfortunate events are most common. Rocks, fallen trees, oyster beds, coral reefs sand bars and just plain junk are a constant threat to the motor’s propeller and shaft.
Even small outboard gas engines are too powerful for SOT and sit-in kayaks, including the widest models. Simply, there is no way to outfit a SOT or sit-in kayak with an outboard motor in a sensible manner. Any SOT or sit-in kayak outfitted with an outboard motor is neither comfortable nor safe to drive because of inadequate means to control and steer it.
Wavewalk kayaks are different from SOT and sit-in kayaks in the sense that they offer the user full control over the boat while they drive it, direct access to the motor, and much more stability than any other kayak does.
In fact, the Wavewalk S4 is more seaworthy than most small skiffs and Jon boats, as can be seen in these short videos:
Wavewalk kayaks offer unrivaled stability, and especially the new 13 ft long S4 that allows big and heavy people to drive it without any problem, facing either forward or sideways –

Here is some exciting news – Wavewalk is offering a new joystick steering system for its 700 series of two-person car-top fishing boat and microskiff. The new system makes steering easier and more comfortable, and safer too if you happen to use a powerful outboard motor such as the 6 hp Tohatsu featuring in this video:
Attaching and detaching this system is a breeze, and it takes seconds, literally. This means that an angler who wants to get the joystick and cables out of their way in order to make room for casting and landing fish can do it effortlessly and in no time, and later reattach the joystick and cables with the same ease.
When you think of a color for a “Fishing Kayak” you typically tend to associate the word Fishing with colors such as dark green or a camo (camouflage) pattern. Color has always been an important consideration in kayak design, and surprisingly there are hardly any white fishing kayaks out there, although most offshore fishing boats (namely motorboats), microskiff and flats fishing boats are white…
Intriguing, isn’t it?
The reason why so few fishing kayaks are offered in white is that most of these small craft are rotationally molded from Polyethylene, and producing a clean white color in this technology is harder than producing other colors.
As for the bigger boats, those are often made from fiberglass and painted white, a color commonly associated with leisure and offshore pleasure boating – You won’t find a camo yacht out there!
So far for the theoretical aspect of fishing kayaks’ colors, and practically, our readers may be interested to know that Wavewalk now offers boats from its 500 and 570 series in white. And since these small craft can be easily and effectively motorized, you can call them by a name other than ‘Kayak’, such as microskiff, catamaran, boat, etc.
