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.

Motorized kayak or microskiff?

The current trend in fishing kayak design is to produce kayaks that are increasingly wide and heavy, and no longer qualify as car-top boats but rather as microskiffs or small boats that require a trailer. This defies the purpose of kayak fishing, but some anglers opt to purchase and use these boats.
The question is, how practical is it to motorize these excessively big kayaks?
It turns out that most large-size fishing kayaks can be outfitted with electric trolling motors that are mounted either on the side or in the middle of the kayak – right in front of the user. It’s not the most practical setup, but some anglers need this extra propulsion power to get where they want to fish, or get back from there, since paddling long distances isn’t for everyone. Some are outfitted with an electric motor mounted in the back, at a big distance from the driver, which isn’t very practical when you go in shallow water where weed and grass are commonly found, and these tend to get entangled in the propeller.
As for outboard gas motors, we haven’t found a single fishing kayak that offers an acceptable solution for an outboard gas motor, as such motors must be stern mounted due to their weight, and mounting a motor that far behind the driver doesn’t work well, for various reasons related to steering, convenience and safety.
The only fishing kayak that can be flawlessly motorized is the Wavewalk, as we’ve already mentioned here.

Wavewalk has recently introduced a set of accessories that enhance the performance of its patented catamaran kayaks in terms of motorizing, and turn them into high performance car-top motorboats, or in other words – personal microskiffs. The difference is not just in the improved performance, but in the looks as well –
With its new, black, inflatable side flotation modules, the new W570 INF 20-15 looks like a rigid-inflatable boat (RIB), which is a type of boat commonly associated with high speed and rescue operations.
The new transparent spray shield makes this little boat look like a marine motorbike, or a twin-hull personal watercraft.

This movie shows this new model in action in the ocean, in choppy water:

Being able to drive this microskiff while standing is not just a useful feature – it’s a lot of fun.  Being able to launch it almost anywhere, without needing to use a boat ramp is a huge plus, and its light weight makes it easy to car top – There’s absolutely no need for a trailer for this craft.

Interestingly, the spray shield is detachable, and it can be removed within seconds if you find that it’s in your way when you fish – After all, this boat offers its user to fish from the front, and not from its sides.

In sum, we see a noticeable upgrade in what Wavewalk offers in the market for portable fishing motorboats.

New speed record for a motorized W fishing kayak

Kenny “One-Shot” Tracy, a W kayak angler from Maryland, broke the speed record for a motorized kayak of the W500 series. He outfitted his W fishing kayak with a 6hp outboard gas motor from Tohatsu.
This powerful engine weighing 57 lbs empty propelled Kenny’s kayak at 13 mph in Chesapeake bay, at 1/3 throttle:

The kayak was stable and its driver stayed dry, and Kenny reported neither tracking nor steering problems.
Before starting his speed tests, Kenny outfitted his W kayak with side flotation.
The motor is mounted on a TMM 20 Wavewalk transom motor mount.

This successful test further reinforces the notion that when motorized, the patented catamaran kayak from Wavewalk can serve as a personal motorboat, or car top microskiff.

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.
