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.

Review of 2013 fishing kayak design trends

A meager harvest when kayak anglers are concerned, and plenty of reasons for a good laugh 😀

2013 hasn’t been much different from previous years as far as fishing kayaks are concerned. The kayak obesity trend keeps being the main one, and it drives kayaks to reach titanic proportions. For example, kayaks that are 35 inches wide and weigh 80 lbs are almost typical, and a kayak that’s over 40 inches wide is no longer viewed as an aberration despite the fact that paddling such a kayak is quite a challenge, and almost impossible to do for medium and long distances. Leviathan barge kayaks weighing around 120 lbs are still considered as kayaks (at least by some) although even a seasoned weight lifter might find it hard to car top one, and people who buy them have to buy a trailer to go with them, which is yet another way to defy the purpose of kayak fishing.
The reason behind the persistence of this trend is the poor stability that fishing kayaks offer to their users, albeit the fact that kayak manufacturers insist that the kayaks they offer are very stable, enough to allow for kayak fishing standing… Go tell this to all those disappointed anglers who purchased such kayaks and found out that reality is different from bogus reviews and staged YouTube movies  🙁

Fishing kayak hulls keep featuring all sorts of weird longitudinal channels and vertical dimples that work perfectly to create more drag and by that further impede the kayaker and make it harder for them to paddle. The infamous scupper holes that were introduced as means to prevent the deck from collapsing but have since been hyped as drainage holes keep conducting water in both directions, which means they also drive water up and onto the deck, and into the paddler’s area.

In the twilight zone, kayaks with integrated outriggers are still being offered although the concept has proved to be rather useless in practical terms. It seems like the failure of the kayak industry to present kayaks that actually work for stand up kayak fishing drives more people to try outriggers.

New designs still appear on the scene, and they make one wonder if kayak designers have any ability to learn from others’ mistakes.

Pedal driven kayaks are still being promoted as the panacea, although reality has disproved most of their manufacturer’s claims as far as practical usefulness is concerned.

Kayak storage keeps relying on hatches, which are often inaccessible to the user while they’re out there in their kayak, trying to fish from it. Such hatches have an annoying tendency to fail to be waterproof, and that’s bad news for your sandwiches!

When ergonomic design is concerned, manufacturers seem to realize that the kayaks they offer are really uncomfortable, so they keep trying to come up with new ideas for seats, although it’s the seat itself together with the L sitting position that cause the back pain and leg numbness problems that so many anglers experience.

Motorizing… well, oddly enough, some kayak manufacturers tell their clients they can outfit their kayaks with powerful outboard gas motors. Naturally, not too many people buy into this nonsensical notion. The most ridiculous case in this regard is a kayak manufacturer who offers his clients to attach their outboard gas engine directly to the kayak’s transom, which like the rest of that kayak is made from a thin, rotationally molded plastic wall… It is only appropriate to apply Hanlon’s razor to this case, and say “Never attribute to malice that which is adequately explained by stupidity.” 😀

And last but not least, fishing kayak manufacturers keep competing with each other by offering an increasing range of useless accessories, from cup holders to stand-up metal frames and stand-up ropes and straps… The latter being pure exercises in futility, at least from the user’s standpoint.

No wonder the Wavewalk 500 keeps being the most loved fishing kayak out there!
