When a fishing kayak becomes a boat, or an ultralight microskiff

Sometimes a technological or design breakthrough pushes the envelope of a product category or class so far that it creates a new type of product that did not exist before. Such thing has happened now with the advent of the new Wavewalk 700 series –

Before the W700 existed, there were several important differences between large size fishing kayaks and small boats.

The most noticeable difference was in width –
Since kayaks’ primary means of propulsion is paddling, they need to be narrow enough to allow their passengers to propel them with dual-blade paddles (‘kayak’ paddles). Boats are not supposed to be paddled but they need to be transported on trailers, which is why their width is determined mainly by the width of roads’ lanes.

The second, and most important difference was in stability –
Being essentially narrow mono-hulls, fishing kayaks are unstable, which is why designers and manufacturers continuously attempt to push the envelope of kayak width by offering excessively wide kayaks (known as ‘barges’) that are quasi impossible and sometimes totally impossible to paddle.
Typically, a monohull fishing kayak’s instability allows an angler occupying its seat to lean slightly to one side, but as soon as they lean more, they lose balance and capsize. By the same token, an extremely large monohull fishing kayak may offer an athletic fishermen to try to stand along the kayak’s center line, but as soon as they move sideways, they lose balance. So basically, the passenger of such large mono-hull kayak is prevented from moving from one side to another, and by this fact such a fishing kayak differs from a boat, which typically offers its passengers to sit or stand on the side of their deck.

When a fishing kayak becomes an ultralight microskiff, or car-top boat

The Wavewalk 700 weighs 80 lbs without accessories, and it’s 31 inches wide, which is fairly slim compared to the average fishing kayak out there, and its very skinny compared to some fishing kayaks whose width exceeds 40 inches. This makes the W700 a lightweight fishing kayak by today’s standards, and a narrow one too, by the same standards.
The W700’s design is based on a patented technology that’s radically different, and this changes the rules of the game as far as stability is concerned.
As this video shows, a full size (6′ / 205 lbs) middle aged passenger can stand up and paddle the W700 in full confidence not just from the traditional position along its center line, but also while standing with both his feet in one of the kayak’s twin hulls:

 

 

This puts the W700 in the category of boats, as far as stability is concerned – a true game changer, and together with its extremely good tracking capabilities, turns it into a high performance boat, or microskiff, when motorized.
This movie demonstrates this breakthrough:

 

 

Taking a second passenger on board

The ability to take a second passenger on board is a third important difference between fishing kayaks and boats: The former are typically capable of supporting a single passenger, and realistically speaking, no one fishes out of a tandem fishing kayak because neither paddling such craft nor fishing out of them is acceptable in terms of ease or comfort. In other words, these kayaks are not remotely fishable in tandem. In contrast, the typical crew size of a fishing boat, even a small one such as a Jon boat or a microskiff, is two, and this difference is critical.

Here too, the W700 breaks the fishing kayak mold by offering full stability and comfort to a crew of two passengers, not just in a tandem paddling mode, but even when outfitted with a powerful outboard motor, as this video shows –

 

The Microskiff redefined

What is a microskiff?

Typically, a microskiff is a small, lightweight, flat bottomed motorboat used for flats fishing as well as in protected bays, estuaries, lakes and slow moving rivers, by a crew of one or two anglers. Some would trace the microskiff lineage to dinghies.
Small and lightweight in this case means a boat transported by trailer, and therefore requiring to be launched and beached at a boat ramp.

Microskiff’s propulsion problem

Microskiff are made to be propelled primarily by outboard motors, and the typical microskiff is too wide and heavy to allow for paddling. This is problematic for a number of reasons –
To begin with, an outboard motor can run out of gas, or stall due to a technical problem, and the electric trolling motor that many microskiff have on board isn’t enough for effective traveling over longer distances.
But more importantly, both outboard gas motors and electric trolling motors use propellers that must be immersed in water at a certain height, so the effective draft of a microskiff under motor is quite high, and often too high for really shallow water, a.k.a “skinny water”.
This problem also limits the typical microskiff as far as launching and beaching locations are concerned, and this means that you must launch and beach it from a boat ramp, which is a major source of frustration over a lot of wasted fishing time.
To add insult to injury, propellers don’t do well in the presence of aquatic vegetation, be it seaweed, grass, etc. This is particularly frustrating to anglers who realize that such waters are among the best fisheries.

Human powered propulsion – Poling, anyone?

Microskiff manufacturers often show pictures of people who use a long push-pole to propel their microskiff through shallow water. This human powered mode of propulsion is indeed possible, but it’s not that practical –
To begin with, poling involves long intervals between each pole push, so the big effort invested in each push that accelerates the boat goes to waste when the boat decelerates while you are busy lifting the pole and sticking it back into the water.  Acceleration is particularly demanding in energy terms, and in other words, the fact that microskiff are wide and heavy makes them lose speed quickly, and thereby drain your energy.
Few people can push a typical microskiff over a distance of more than several hundred yards, and that’s not enough in terms of real-world fishing.
On top of this, the hull of a typical microskiff is not designed for effective tracking – It’s neither very long nor narrow, and it lacks elements such as fins, skegs or tunnels that could improve its directional stability. The result is that poling in a straight line becomes harder, which means you waste an additional and considerable amount of energy because your microskiff zigzags instead of going straight forward.
Poling is far from being on par with more effective means of human powered propulsion such paddling and rowing.

Conclusion – A better microskiff should allow its crew to go in shallow water and vegetation-rich water in a human powered propulsion mode other than poling, and preferably paddling, since effective rowing requires good technique that can be acquired only through much practice.

An ideal microskiff for real-world fishing

Ideally, a microskiff should allow for either a crew of two fishermen or a solo fisherman to launch, beach, motorize, fish and paddle in any type of water, whether standing up or seated. This means that such a boat should be highly stable yet narrow enough for effective paddling, and only the patented, catamaran-style Wavewalk™ from the new 700 series offers to work as a both a full tandem and solo skiff in the sense that it works perfectly well for one person too, when the second crew member is missing. The fact that the W700 features two long and narrow catamaran-style hulls helps it track better than other craft of similar size, and that helps poling as well as paddling it, with either dual-blade (kayak) paddles or single-blade paddles – canoeing style.

The ideal microskiff should also be lightweight enough to allow for trailer-free transportation, and car-topping by one person, in case no fishing buddy is present. Again, the only two-person microskiff that offers such advantage is the new Wavewalk™ 700, which weighs just 80 lbs without a motor and accessories.  In fact, this weight is lower than that of most high-end fishing kayaks out there, including sit-on-top (SOT) and sit-in models, especially tandem fishing kayaks, which are heavier than regular ones.

Trailer-free with triple propulsion capability

The redefined microskiff is trailer-free I.E. easy to car top even for one person, suitable for choppy water, skinny water and vegetation-rich water, and accommodates two full size fishermen fishing standing in comfort. It can be easily and comfortably driven with a powerful outboard motor of up to 5 HP, as well as with electric motors.
One or two people can easily paddle it kayak-style or in the traditional canoeing style, and it lends itself to poling more easily and effectively than any other microskiff does, including solo skiffs, I.E. microskiff for just one person.
Such is the new Wavewalk™ 700 series.

More insight on the design of the W700 catamaran – kayak – boat…

Wavewalk prefers to use the term Twinhull rather than Catamaran to describe its patented invention because its design does not fit the typical catamaran form, which implies two hulls of the same size that are placed at a considerable distance from each other, and attached by means of a wide structure (deck) from the top of which the boat’s users operate it –
The twin hulls of the Wavewalk boat form are close to each other, and they are attached by a narrow bridge located at the center of the boat’s cockpit. The passengers sit on top of the bridging structure called ‘Saddle’, and they operate the boat from within its cockpit.

Like all catamarans, the W boat design is subject to forces that pull its two hulls apart, especially under heavy loads. Different catamaran designs address this problem by different means, depending on factors such as the boat (or ship) size, materials from which it is built, etc.

Wavewalk’s first production series was the 300 (2004-2010) and its second production series is the 500 (2009 – ). Wavewalk chose rotational molding as a production technology for both series, and in fact, most modern kayaks are rotationally molded from Polyethylene, which is the most suitable polymer resin for this application.  Since 2014, boats from W500 series are outfitted with a structural element called ‘Saddle Bracket’ which takes care of excessive loads.
The 700 series is bigger than the 500 series (dubbed the world’s best one-person fishing boat), since it is designed to carry a crew of two large size anglers and their fishing gear, while being propelled by an outboard motor.  Due to technical limitations stemming from its large size and complex form, it could not be rotationally molded in one piece. Therefore, Wavewalk had to come up with a two-part solution, as shown in this instructional 3D animation video:

 

The Saddle is attached to the Twinhull by rivets. After the riveting is done, the rivets are waterproofed.

This innovative solution offers several benefits to the users, including light weight (just 80 lbs for the basic W700 model), resilience, strength, and durability.
The W700 saddle is watertight, and provides flotation in case of an accident.

A white fishing kayak? Well, you don’t have to call it a kayak…

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.

The typical fishing kayak is a cluttered barge

This short review of recent kayak design articles highlights some aspects of the common fishing kayak.

The first, and probably most striking thing about the typical SOT, sit-in or hybrid fishing kayak that’s offered in stores or online is its size – It is huge, and consequently heavy and hard for one person to carry and car top, as well as hard to paddle, especially in wind and current.
Those kayaks seem to have crossed the line between a kayak and a boat, or a skiff, since practically speaking they require transportation by trailer. And indeed, some manufacturers already refer to their larger fishing kayak models as boats, not because of their performance or some additional functionality, but due to their size.
Needless to say that this fact alone is evidence that such kayaks defy the purpose of kayak fishing.

The second most striking aspect of those large-size fishing kayaks is the dysfunctional clutter in their cockpit and deck that seem so crowded with fishing accessories and just ‘stuff’ that the angler sitting or attempting to stand in them literally has no room to do so. These objects range in size, from small cup holders to large size lean bars, and their presence in the kayak’s cockpit is not only unnecessary to the angler, it is clearly counterproductive.

The third interesting thing about these larger than life (I.E. too large for real people to fish from in real life) kayaks is the absence of hydrodynamic design in them: They are not even close to conform to basic boat design standards or even to common sense: Not only are they much too wide for their length, which slows them down and makes them track poorly and require a cumbersome rudder – their underside features a variety of design elements that are extremely counterproductive as fare as speed is concerned. Such elements can be multiple scupper holes and molded-in channels, fins, and even a skeg.

Ironically, none of these accessories, systems and design elements offers a real solution to the fundamental problems that the average angler experiences when using them –

These unsolved problems in these common fishing kayaks are:

1.  Poor ergonomics, meaning mainly lack of comfort, early fatigue and back pain, as well as bad bio-mechanical design, which the angler feels as a restricted range of motion in both paddling and fishing. The new beach seat style kayak seats are obviously a botched attempt to address this issue, as foam filled seats failed to do so in the past.

2.  Insufficient stability albeit the fact that these fishing kayaks are extremely wide.

3.  Wetness as a result of the kayak offering too little or no free board, and scupper holes that conduct water upward onto the deck and cockpit, a problem annoying to a point that  manufacturers have to offer scupper plugs…

4.  These kayaks are as wide as canoes and as as sluggish and unfit for paddling in strong wind, waves and other real world factors.

5.  With all the stuff tucked on board a typical SOT, sit-in or hybrid fishing kayak, such craft still scores very low in terms of storage, as one or more hatches address neither the need for enough storage space nor for adequate accessibility to the gear stored inside.

In contrast, the Wavewalk 500 series of twin hull kayaks offers a high level of fishability in all these factors.
