Wavewalk announced the new Series 4 (S4) of portable boats (car-top boats) that are extremely stable even by comparison to larger boats that require transportation by trailer. Still, the 38″ wide S4, which feature slated cockpit sides designed to facilitate paddling, will work well enough as paddle craft, namely for kayaking, canoeing, and kayak fishing.
In this case, portability also means gaining extra mobility through the option to launch anywhere, and the option to paddle effectively means being able to go in shallow water where motorized fishing boats are prevented from going, as well as in weeds, and no-motor zones (NMZ).
The ultralight skiff (98 lbs) is by no means limited to being a solo skiff, and with a load capacity of over 600 lbs it can take two big and heavy anglers on board, or three lighter persons, plenty of fishing gear and camping gear, and a powerful outboard motor of up to 6 HP.
This will be the first skiff from Wavewalk to feature a traditional stand up casting platform at the bow. This will make the boat perfectly adapted to fishing the flats with a crew of two, and still, its extreme stability and twin-hull (catamaran) design guarantee offshore capabilities beyond what is expected from small skiffs and Jon boats.
This hydrodynamic advantage, which pertains to tracking and seaworthiness, is enhanced by the ergonomic advantage provided by the saddle seat, which is similar to seat that feature in personal watercraft (PWC), also known as jet-skis.
The following video shows the smaller, popular Wavewalk 700 in an offshore trip to the Elizabeth islands, south of Massachusetts. The new S4 will perform even better in such applications:
This new, versatile skiff will be available starting in April, and it is offered at a $2,505 price point, without accessories.
This website, Micronautical.com rarely features kayak reviews because it is about kayak and small boat design, and it discusses closely related subjects such as outfitting. The idea behind Micronautics is that very small boats (e.g. kayaks) are so different from bigger ones that their design requires a totally different approach and science. These things are not merely theoretical, but they are developed by Wavewalk and successfully implemented in its kayaks and portable boats.
This is why it should be interesting to feature here a review of the new Wavewalk 700 that this boat’s designer himself wrote:
Review of my Wavewalk 700
Why am I writing a review of a boat that I created?..
Good question, especially since I’ve already written several articles about it…
The answer has two parts – The first is that many months ago, before we launched this product, I had promised some Wavewalk fans that I’d write such a personal and professional review on this new boat. The second reason is that now that the initial phase of launching this product is winding down, and it got such positive and exciting reviews from clients and fans, I also feel like talking about it from a personal angle and a professional one, but this time more as a designer than a marketer.
But this is in theory… – Is it possible for someone like me to fully dissociate the personal from the professional, and the designer from the marketer? Well, I think it would be hard, which is why I wrote that disclaimer at the top of this page 🙂
Boat first, kayak second
Where did the W700 come from?
First steps – The 300 series
Back in 2004, when we came out with our first product, the W300, we called it a Personal Catamaran, and then a W-boat. Soon after, I had thought about motorizing it and about creating future models that would be small, “personal” boats, with spray shields and steering bars:
However, the W300’s main application was kayaking, namely paddling with a dual-blade paddle, so we gradually started calling it W-kayak, and as anglers discovered it shortly after, it became known as a Wavewalk fishing kayak. The boat’s main commercial application had defined it.
Several Wavewalk fans such as Rox Davis outfitted their W300 with electric trolling motors, and one outfitted his with a 2.5 HP Suzuki outboard, but although their W300 boats seemed like fun to drive, some things were still missing in terms of comfort and performance…
The next step – The 500 Series
In 2009, when we launched the W500 series, it was primarily a fishing kayak, and we knew that more anglers would motorize it, which indeed happened.
Around 2011, following Sungjin Kim’s successful outfitting of a W500 with a 2HP Honda outboard motor, we became seriously involved in developing the motorized application for our kayaks… We developed transom motor mounts, spray shields and inflatable flotation modules to go with them, and we tested and demonstrated their performance, both with one person on board (I.E. the driver), and with an additional, lightweight passenger.
People became increasingly interested in this concept, and at the same time, we became aware of its shortcomings , mainly the limited load capacity and limited stability offered by this 29 inch wide design.
Early in 2014, Kenny Tracy, a.k.a. ‘One-Shot’, outfitted his W500 with home-made Styrofoam side flotation and a 6 HP Tohatsu outboard, and soon after drove this boat at 13 mph, at 1/3 throttle, thus shattering the previous speed record for it, which was just under 10 mph… What first seemed like a crazy idea of a motorcyclist who likes to tinker with boats turned out to be a pivotal event.
Soon after Kenny’s speed record, I purchased a 6 HP Tohatsu outboard, knowing it was overkill for the W500, but I had plans…
Kenny’s breakthrough acted as a catalyst that led us to developing the large-size inflatable flotation tubes that together with the Spray Shield served to create the W570 model, which is the intermediate concept between the 500 and 700 series.
We realized that if we wanted to offer a motorized watercraft that can take two full-size American anglers with their fishing gear, as well as go at high speed in choppy water, we’d need to come up with an altogether new product, I.E. a boat that would be bigger and more stable than the W500, but lightweight enough for one person to car-top, and narrow enough for paddlers to paddle easily, effectively, and comfortably.
The design spiral of the 700 series
This was the beginning of process known as Design Spiral, which is typical to the way new products come into being. The main reason why this process took a long time, and as a result we missed the main part of the 2015 season… was the fact that if we simply enlarged the W500 design, there would have been no rotational molding machine capable of effectively producing it. So we spent a long time and much efforts looking into other molding technologies and other materials, only to realize that Polyethylene (PE) was the best material as far as resilience and durability are concerned, as well as price, and we wanted to have a product that offers the most with regards to all these parameters.
This basic research phase brought us back to rotational molding, and we began exploring ideas that would allow us to produce this new and bigger boat on existing machines. Our molders helped us by providing insight on the solutions that we explored, and after several months, we got their approval for a solution like which no one has come up with before – Essentially, in order to create the W700, we had to innovate in rotational molding…
In essence, the W500 is molded like any other kayak, namely in one piece, out of one mold, while the W700 is molded in two parts, out of two separate molds. These two parts of the W700 are the Twinhull and the Saddle, and they are assembled together at the factory (watch video » )
The bigger size of the W700 and the need to create industrial tooling that consists of two cast aluminum molds instead of a single one practically doubled our investment, compared to what we had paid in 2009 for the W500 tooling.
What we wanted the W700 to be
In the period that preceded the creation of the computer aided design (CAD) files for the W700 molds, I had many interactions with clients and dealers who were interested in this project. Among them were Michael Chesloff and Steve Lucas, to name a few. These people provided their ‘wish lists’, and voiced both their concerns and recommendations. It became clear to me that unless the new product is not just better than the W500, but a true breakthrough in boating and fishing, it might not justify itself. And by justify I mean commercially, in dollar terms, with an investment of nearly $80,000 in the tooling, including adaptations performed at the rotational molding plant after the molds got there, and not including the long hours that we spent on creating the CAD files for it.
Paddling vs motorizing
The main reason why SOT and Sit-In fishing kayaks are so sluggish is their excessive width, which generates so much residual resistance (Rr), also known as form resistance from the water they travel in. This wouldn’t have been an issue with the W700, since it is a true twin-hull (catamaran) featuring a pair of very narrow hulls. However, the extreme width of those other fishing kayaks (some exceed 40 inches…) works to make them sluggish also by preventing their users from moving their paddles effectively.
As for motorboats, even the smallest ones are stabler than kayaks, because they are much wider, but you can’t paddle a boat, practically speaking.
We wanted the W700 to be a great paddle craft even for one paddler going in rough water, which meant keeping this boat slim, but we also wanted it to be a great motorboat even at high speed (for its size), which meant that we had to increase its width in order to make it more stable than the smaller, 29″ wide W500.
Overall size, cockpit size and features
The overwhelming majority of anglers who go on water don’t fish from kayaks – They fish out of motorboats. And while most of these craft are designed to take more than two large size fisherman on board, it is quite rare to see a boat manned by a crew of more than two. In fact, the typical crew of a recreational fishing boat is two. So the W700 was required to take two large size American guys on board, plus their fishing gear, an outboard motor, and the fish caught…. Adding up all these things and their aggregated weight gave us the volume (number of cubic inches of buoyancy) that the W700 had to have, and since the boat’s width had already been decided, as well as the saddle’s width that was known after a decade of successful use in the W300 and W500 series, it was the aggregated load requirement that decided the boat’s total length from end to end.
We knew that the W700 would be much stabler than the W500, so we used the opportunity to make its saddle a bit higher, for the benefit of passengers with long legs, arthritis, neurological problems, and for those who had joint replacement surgery or suffer from other disabilities in their legs.
Then we faced the question of the cockpit size, or basically its length. There were two approaches to consider – making the cockpit short and the hull tips long could have given the boat a sporty, ‘cool’, and possibly ‘futuristic’ look, while making the cockpit very long would have been more practical in terms of passenger space and room for anglers to cast and fight fish. We thought that for our clients, the latter consideration was more important, so the question became how to maximize cockpit length without overdoing it…
Here again, the answer came from experience and common sense, with some simple calculations – We knew that a heavy driver might prefer to sit next to the transom while they operate a motor weighing 30 lbs to 60 lbs, and in any case, they’d be sitting next to the motor when they start it. This meant that we had to make the stern buoyant enough to support the weight of both driver and motor, and since the width of the boat was already given, we had to provide this extra buoyancy at the stern by placing the motor mount and the motor attached to it away from the rear tips of the hulls. We set the distance based on the tests we had run on the W570 outfitted with the 60 lbs 6 HP Tohatsu outboard.
As for the cockpit front, we knew from previous experience driving the W570 in choppy water that bumping into waves at high speed can generate much spray, so we’d better keep the front end of the cockpit at a reasonable distance from the hull tips.
In this sense, the actual length of the W700 cockpit, which is 7’10” reflects what’s left after we applied these requirements.
Another thing we had noticed while driving the W500 and W570 was that the motor being closer to the driver helps the driver start it, manipulate its controls, and drive the boat while being seated or standing in the middle of the cockpit. For these reasons we designed the ends of the W700 cockpit’s spray deflector as straight lines and not curved ones, thus allowing for the closest possible distance between motor and driver.
And if the reader asks themselves why we designed the front end of the cockpit in the same way, the answer is that following our clients’ insight we thought that some anglers would want to attach a powerful outboard gas engine in the back of their W700, so that they could cover the distance to their favorite fishery in the shortest time, and use a small electric trolling motor attached to the front once they arrive there and start fishing.
In other words, we planned for a scenario typical to what anglers commonly do when they fish out of popular boats such as Jon boats and bass boats.
This is to say that among various other considerations, we created the W700 as an alternative to these popular boats.
Although a 3.5 hp outboard is sufficiently powerful for the W570 and W700, the reason we got a 6 HP Tohatsu outboard for our tests and demos is because the visionary Kenny ‘One-Shot’ Tracy chose this motor after he had found that it’s the smallest outboard that can be outfitted with an alternator, namely charge a trolling motor’s battery. That sounded promising…
Another reason why we got a 6 hp motor that’s overkill by a considerable margin is that many boat owners overpower their boats just because they can, and we wanted to know what this involves.
And there are more reasons, but we’d rather talk about them when we have something to show…
Some people asked me how come we engaged in such a project without first creating a prototype for this new boat. This question is well placed, naturally.
The answer is that we had tested a similar although smaller product in the form of a W570 outfitted with a 6 hp motor. Besides, creating a realistic prototype of the W700 was technically impossible, since it needed to be done in Polyethylene, and that would have required fully developed and rotational molds…
Making a full-size W700 prototype was possible only if we did it in fiberglass or carbon fiber, and it would have cost tens of thousands of dollars, and take many months to complete. Realistically, such a fiberglass or carbon-fiber reinforced resin W700 prototype would have not told us anything interesting about the same boat made from Polyethylene.
Timing is key
We finished the work on the CAD files for the W700, and sent them to the mold makers, who used them the create ‘patterns’, a.k.a. ‘plugs’, which in their turn served to create ‘sand’ molds into which the mold makers cast the molten aluminum. Once the aluminum molds were cast, the mold makers outfitted them with steel frames that would be used to attach them to the rotational molding machines, and polished them. The last phase of mold making was coating the inside with Teflon. Coating molds is required in order to make it easier for the rotational molders to extract the Polyethylene ‘parts’ from the molds.
Making a cast aluminum rotational mold of this size is a lengthy and complex process that’s prone to delays, which was the case with the W700 project, and only in the second part of August were we able to start shipping the first W700 units to clients and dealers who had ordered them weeks and months before.
In this first batch, we got a demo unit for ourselves –
Testing the W700
Some people who found it easy to car top their W500 worried that car topping the heavier W700 would be significantly harder for them. I had car topped a W500 with a 2 hp Honda outboard attached to, so I wasn’t worried about it, and indeed, one of these clients who had gotten his W700 a few days before I did, reported that car topping it was a breeze. It was indeed.
Our first test took place on lake Massapoag, on a sunny but windy day in late August. We didn’t take a motor with us since we knew that we’d have no time to test the boat with a motor on that day. In the days before I received my W700 I had already gotten very positive comments from a couple of clients who had theirs delivered to them before I did, so there was little anxiety on my part in that first time I tested this boat in real life.
Besides, I had tested it so many times in ‘thought experiments’ that I pretty much knew what to expect, kind of, although real life experience is different, being based on sensory input and not on technical knowledge aided by a trained imagination.
I entered the white W700 cockpit from a dock and started paddling standing, and I was impressed by the new level of stability that I was experiencing, although I wasn’t really surprised, because this had been my main concern and therefore my focal point… but then, after a few more paddle strokes I had my first pleasant sensory surprise: This boat was fast! It glided like a champ, and tracked like a dream… -“Wow!” I thought to myself, “What a nice bonus!”. I had expected the W700 to be faster than the W500, but imagining speed in paddling is probably harder than imagining stability.
The next thing I tested was ease of turning, and here too I had a delightful moment, as I realized that the boat was easy to turn – “The smaller draft helps!” I thought to myself.
I paddled back to the dock, on which my wife was standing with a video camera. I had planned to demonstrate the boat’s stability the way I did back in 2010, when we shot the ‘Super Stability’ movie with the W500… So I faced the dock, and started jumping up and down and from one foot to another, trying to generate a lot of spray in the process, as I had done with the W500… but the W700 didn’t cooperate – It hardly budged. A 200 lbs guy jumping in it and trying to get it to sink in the water and pop out wasn’t enough. It didn’t work even as I jumped energetically from side to side.
After a couple of minutes of vain attempts, I realized that I was in a ridiculous situation, and I tried to think about another way to demonstrate this boat’s incredible stability. The way I did it came straight out of a designer’s imagination: I stood with both feet in one hull, in a rather awkward posture (try standing with one foot in front of the other…), and I paddled on both sides of the boat. The result can be viewed in our ‘Absolute Stability‘ video, which has made quite a few jaws drop 🙂
Later, I thought about this test and realized that it proves ‘boat stability‘, namely a degree of stability that kayaks cannot offer, since they allow the user to sit or stand along their center line, but not to stand on one side of their deck, or hull. This is something that only a good size boat can offer, and the W700.
Next came a series of tests that showed how easy it is for the user to turn inside the cockpit. This is of particular importance due to the advantage of starting the outboard motor while facing it (I.E. facing backward), and then, once it’s on, turning and facing forward. Later, in other occasions, we showed how this works perfectly when the boat is motorized. In principle, this is possible with a W570 too, but it’s not as easy as it is in the W700.
After we ended that video shooting session, I took my wife for a tandem ride in the boat. She sat in the front, without paddling, and I stood at the rear and paddled. This time I had a double surprise – The first was that the boat glided very nicely on the choppy water without me putting much effort in paddling, although I had to move an additional 135 lbs… “It’s the effect of the bigger load capacity!” I thought to myself.
Then, after a couple more minutes of paddling this way, I noticed that I wasn’t paying any attention to stability… It was like the issue of stability had been erased from the agenda – Stability had become a non-issue, and I was no longer required to address it. “Nice!” I thought to myself -“This boat is instability-free”.
Michael Chesloff called this boat “ridiculously stable”, and I like this expression because it captures the feeling of incredulity mixed with relief that one feels when they first paddle it.
Testing the W700 with a 6 hp outboard motor
We weren’t going to test the W700 with a 2 hp outboard because doing it with such a small outboard would have been ridiculous, so we ran the first test with our 6 hp Tohatsu outboard, which can propel boats weighing up to 3,000 lbs, according to its owner’s manual. The W700 weighs 80 lbs… the motor and transom mount weigh a little over 60 lbs, and I weighed about 210 lbs at that time. That’s a total of 350 lbs. These numbers should tell the reader by how much the W700 we tested was overpowered.
The spot we picked for testing the W700 and shooting our demo video was Westport Point, in Massachusetts’ South Shore, and if the water surface there looks interesting in video it’s thanks to fast and sinuous tidal currents and big wakes generated by motorboats going in all directions. The team consisted of two camera persons – namely my wife and my younger son, and me in a dual role of test driver and director.
Later, my wife joined me in the boat. She first sat in the front of the cockpit facing forward, and while I was driving, she turned around and sat facing backward. She did it effortlessly, and I didn’t have to make a particular effort to balance the boat while she was turning.
The cockpit felt very spacious. My wife and I invited our teenage son to join us on board for a family tour, but he preferred to stay on shore and keep shooting video…
The boat behaved very well – It was stable both in terms of lateral stability and directional stability (tracking), easy to maneuver, dry, and simply a pleasure to use both solo and in tandem, seated and standing.
Starting the motor while facing backward was easy, and turning in the cockpit in order to drive facing forward was easy too.
I steered using the same articulated (U-jointed) tiller extension that I had used before with the W500 and W570, and it worked very well.
My only concern was that with a 6 hp motor the throttle never passed the 1/2 mark, even when the boat was going fast… This meant that somewhere in the back of my mind I had to pay attention to the throttle, because with so much extra power available in the engine, a wrong twist of my wrist could have made me lose some control over the boat, and such glitches are unwanted by definition.
The new saddle design performed exactly as we had intended it to. The combined effect of the multiple molded-in brackets along the saddle’s length and the wooden bracket at its rear end provided the feeling of sturdiness and comfort that I wanted to achieve when we worked on this new design.
Being 6 ft tall, I felt more comfortable sitting a little higher than in the W500.
Joystick Steering – from fishing boat to sports boat
The two movies we shot at Westport Point showed the W700 as a fishing boat and a utility boat (tender), as well as small touring boat, and it looked good in all these applications. But I wanted to take it further – I wanted to eliminate my concern about this boat being overpowered, and turn steering it into a pleasure by itself – a means to have fun.
I sensed that the W700 had the potential to be used purely for the fun of driving it, and not just for transportation or going places. In other words, it could be used as a sports boat… (I can see some Wavewalk fans and dealers raising an eyebrow after reading this sentence…)
To make a long story short, I pushed forward the development of a joystick steering system that I’ve been thinking about for some time, and went together with our camera team to lake Massapoag, to test this system in real world conditions. And indeed, the conditions at the lake that day were as ‘real’ as can be – It was a particularly cold day for October, and the wind was blowing hard, as one can see in the movie…
Once again, starting the engine was easy, and so was driving, and… it happened! – I forgot about the powerful motor, and once I saw that the joystick was working flawlessly, I started fooling around with the boat, alternating between driving seated and standing, and enjoying the speed and freedom of motion that it offered. It was pure fun, exhilarating – except for the fact that the water level at the lake was low at this time of year, and I had to be careful not to get too close to shore so that I won’t run into underwater rocks, as I did the year before while I was driving the W570 at the same place…
What is the W700?
Silly question? Maybe. After all, what matters is how people see this boat and use it, and not words put together by its inventor-designer-manufacturer-marketer. However, better definitions could help people better understand this new type of watercraft.
Although the W700 bears similarities with the W500 as well as with other types of watercraft, it is unique in more than one sense. Moreover, better definitions can help us, at Wavewalk, find more markets for it, and improve the user experience of people who paddle it, drive it, and fish from it.
The bottom line is that the W700 is an exciting watercraft with an exciting future!
Anglers who dislike wasting time launching and beaching their boat at boat ramps dream of a car-top boat, and the Wavewalk® 700 can be easily car-topped, even by one person, as seen in this video:
But this is not where the advantage provided ends – The Wavewalk® 700 is not just a car-top boat, it is also a portable boat, namely one that that can be easily carried (portaged) from the transporting vehicle (car, SUV, pickup truck) to the beach, and back, even on rough terrain.
This can be done just by dragging the boat on the ground, and even one person can do it, as seen in this W500 video:
It’s harder to do with an outboard motor is attached to the boat, but still possible if the boat is outfitted with a pair of wheels, which can be carried on board once the boat has been launched.
Here is some exciting news – Wavewalk is offering a new joystick steering system for its 700 series of two-person car-top fishing boat and microskiff. The new system makes steering easier and more comfortable, and safer too if you happen to use a powerful outboard motor such as the 6 hp Tohatsu featuring in this video:
Attaching and detaching this system is a breeze, and it takes seconds, literally. This means that an angler who wants to get the joystick and cables out of their way in order to make room for casting and landing fish can do it effortlessly and in no time, and later reattach the joystick and cables with the same ease.
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.
Before the S4 came out, there was no kayak out there that was 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:
