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 two-person motorboat that you can easily paddle and car top

It’s almost here, the 700 series from Wavewalk.

People who fish out of a W500 or W570 would tell you that it’s the best fishing kayak out there, or the best one-person fishing boat. Soon (in July), Wavewalk will started shipping boats from its new 700 series, and its goal is to have people who fish from it say that it’s the world’s best two-person fishing boat.

What attributes will this new craft have that could turn it into the world’s best two-person fishing boat, according to its future users?

Well, to begin with, it’s roomy enough for two large size anglers to stay in and fish. Its 7’8″ long and 31″ wide cockpit allows for this. Its patented twinhull form provides the stability for such a crew both when fishing (seated or standing) and motorizing.

With its 580″ load capacity, it couldn’t take more than two large-size anglers and their gear, plus an outboard motor, but we’re looking for the best two-person fishing boat, aren’t we? It is true that most fishing boats out there have a bigger load capacity, and can take a crew of more than two anglers, but the reality is that in most cases, the crew is comprised of one to two passengers, and seldom more.

The basic 700 model weigh 80 lbs without the motor attached to it. This means that it’s a car top boat even if one person has to transport it.

So what benefits does the 700 come with, and what problems does it solve?

To begin with, the W700 solves the problem of boat transportation. It’s a trailer-free boat, and this means it takes less storage room at home, it doesn’t require a trailer… and it enables its users to launch and beach anywhere they want, without having to start their fishing trip at a boat ramp, and waste so much time there, on the way there, and on the way from there…

The W700 is also easy and effective to paddle, either with a crew of one or two. This is a significant advantage for those who like to fish in shallow water, where motorboats are prevented from going, as well as in water where vegetation abounds, which is also not a good place for motorboats to go. And last but not least, this boat will allow you and your fishing buddy to fish in no-motor zones (NMZ), which typically have a good reputation as bountiful fisheries.  And by the way, the W700 will be equally suitable for kayaking and canoeing, that is propelled with dual-blade (I.E. ‘kayak’) or single-blade (canoe) paddles.

The W700 would be a perfect microskiff for flats fishing, as being both stable and lightweight it would also work great as a poling boat.

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.
