Here is a glimpse into the process of making a mold for Wavewalk’s newest portable skiff, the Series 4 –
The pictures below show the wooden pattern produced from solid wood and hard rubber from the CAD (computer Aided design) file for the product. This first-generation mold will be used to produce a second generation mold called a sand mold. The mold makers will cast molten aluminum into the sand mold, and produce the actual rotational mold in which molders will pour Polyethylene resin, and produce the Series 4 boats.
When kayaks are concerned, tall people are more challenged than short and average height people, and so are heavy people. Tall and heavy people, a.k.a. “big” are particularly challenged, especially if they are elderly too.
What’s the problem?
Being tall means that your center of gravity (CG) is higher than that of a shorter person. This is especially true for men, whose center of gravity is higher than that of women. A high center of gravity can be a serious problem if you’re using a narrow and tippy kayak, and it can be a mere source of constant concern when you’re using a wider and stabler kayak. Being tall means that you won’t be able to paddle standing in most fishing kayaks out there, and you won’t be able to fish standing either. This is too bad, since paddling standing if fun, and it works better for sight fishing. As for fishing standing, it is a basic right of anyone who fishes from a boat, and a good fishing kayak should offer it to anyone – no ifs and buts.
Another problem that tall people experience when paddling common (sit-in and SOT) kayaks and fishing from them is discomfort, beacuse their legs are longer, and therefore their feet, which serve as forward points of contact with the kayak itself, have less leverage on the boat, due the longer distance from the person’s core and torso, where balancing takes place. In other words, a tall kayaker’s legs are required to work harder to maintain the seated posture, and to balance both the kayaker and their kayak. This continuous effort is unpleasant and often results in discomfort, back pain, and fatigue.
Heavy people –
Heavy people who sit in a regular kayak, be it a sit-in or a sit-on-top (SOT), experience discomfort from several factors: The first is the fact that when their legs are stretched forward, in front of them, their abdomen is compressed between their torso and their lap. This pressure is both unnatural and uncomfortable.
The second factor is their upper body that weighs on their buttocks and coccyx without their legs supporting any of this weight, as they otherwise would when the person is seated on a chair, or a bench. This problem occurs because the heavy kayaker’s legs are stretched in front of them, in the L posture that as become the hallmark of kayaking discomfort.
And let’s not forget that if a person is really heavy, they might be challenged when it comes to balancing their kayak.
Tall and heavy, i.e. “Big” people –
People who are big, that is both tall and heavy, aren’t that rare in the general U.S. population, but you’d hardly find them in kayaks, because kayaking and kayak fishing are too much of a challenge for them. An additional hardship that such people experience with kayaks is getting into the kayak and out of it. This is especially true with traditional sit-in designs, but it’s also true for SOT kayaks.
The old age factor
The above said is particularly problematic for tall, heavy and big people who are elderly. Being older often means that one’s sense of balance could be impaired, and older people are usually less supple and agile than younger folks are. On top of this, many elderly people suffer from various conditions involving back pain, joint pain, arthritis, and various disabilities and sensitivities that further prevent them from using regular kayaks, especially for fishing, which typically requires staying in the kayak for longer periods of time.
The kayak for tall, heavy, big and elderly people
Wavewalk’s new 700 series solves all the above problems. Kayaks from this series can easily accommodate very tall people, who comfortably ride the kayak’s 15″ high saddle, without being forced into the L posture. These people can stretch their legs anytime they feel like, stand up easily, as well as paddle and fish standing up. Going back to the seated position is not a problem either – It’s done intuitively and effortlessly.
There is no kayak out there that’s more stable than the W700, not even the world’s most stable kayak until today, the W500.
The W700 is so stable that a 200 lbs, 6′ tall middle-aged guy can stand with both feet in one of its hulls, and paddle on both sides of the kayak, as shown in this video:
But this absolute stability isn’t the only advantage that big and tall users get from this kayak: Both getting into the cockpit and out of it is a breeze, even for this 300 lbs, 6’3″ tall, 65 year old fisherman, who simply walks into this kayak, and immediately starts paddling standing in it:
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.
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 –
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.
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.
