A breakthrough in skiff design and performance

Skiffs are small, open deck, typically flat bottomed boats that are similar to Jon boats, except for some characteristic structures such as a frontal casting deck, or platform, which most skiffs feature.
Skiffs are powered by outboard motors, and they are used mostly for recreational fishing in flat water, especially shallow water. A skiff may be required to travel through moving water, such as bays, tidal currents, and rivers.

The smaller skiffs are sometimes called micro skiffs, or microskiffs, and the smallest of them can carry no more than a single passenger going on a solo trip.
Even these skiffs of solitude are too heavy for car topping, especially by one person, and they lack a proper casting platform at the front. The best performance these very small skiffs can achieve in transportation terms is fitting on a pickup truck bed, and since the most lightweight of them weighs 150 lbs without the motor, one wonders how uploading and downloading it is even possible.

This sub category of solo skiffs is rather worthless for paddling, which can explain the motto “Forget About Paddling” coined by a manufacturer of one of these micro skiff.
In shallow water, paddling is the best alternative to motorizing, since motors are often prevented from proper functioning in such waters, be it as a result of too much draft, vegetation, underwater obstacles, or regulations. Therefore, the notion that anglers fishing out of small skiffs can forget about paddling is senseless.
The S4 cockpit features slanted sides that make it easy for the passengers to move their paddles closer to the boat, so this 38″ wide craft paddles more ergonomically, and feels like a narrower kayak in this sense, although in stability terms it’s more stable than any kayak.
And as for bigger skiffs, their users are forced to forget about paddling, and that’s too bad, since it reduces their mobility and limits their ability to fish in skinny water, and increases their exposure to unpleasant surprises at low tides, etc.

Lackluster performance can be expected from these small skiffs when it comes to seaworthiness, namely performance when driving or fishing in the ocean or in other moving water, and providing enough stability in the presence of wakes that big motorboats generate. This is reminding a similar problem that many Jon boat passengers and anglers experience.

The skiff is a successful boat design, especially in the southern states, where flats fishing is popular. However, as popular is it is, this design has left many problems unsolved, or poorly solved, so far.

The Wavewalk S4 – a revolutionary skiff, or a new type of boat?

The Wavewalk S4 performs in various conditions

Legally, the S4 is a kayak, and technically, it can be described as a catamaran. This is not a good start for a boat that claims to be a skiff. But its shallow draft and front deck can serve to justify its inclusion in the skiff category, at least in the sense that it offers to do what skiffs do, just better.

Better skiff in what sense? –

  1. Weight and portability – At 98 lbs without accessories, the S4 is significantly lighter than the lightest micro skiff out there. It is the only skiff that one person can easily car-top.
  2. Load capacity – With a weight to payload ratio that’s over 1:6 (the S4 can carry over 600 lbs on board), the S4 can carry up to three adult passengers or two large-size fishermen even in a motorized mode. This is over twice the load capacity of the micro skiff that’s closest in size to the S4 in weight, and it’s comparable to the performance of bigger skiffs.
  3. Stability – The S4 is more stable than any other small skiff, and the stability it offers is comparable to the stability that medium size skiffs offer.
  4. Balancing capability – A skiff that’s considerably bigger than the S4 can be more stable in absolute terms, namely resistance to change, but no skiff offers its passengers to ride a saddle seat that only high performance personal watercraft (PWC, or jet-ski) feature. This type of seat allows the users to balance themselves intuitively, and more effectively than any other type of seat does.
  5. Versatility and mobility – The S4 is the most versatile of skiffs, in the sense that it delivers top performance both when motorized and in a paddling mode. There is no other vessel whose user can host two extra passengers on board while driving in moving water, and later paddle it effectively in a solo mode on a long trip. Similarly, there is no other vessel that performs well both in the ocean and inland, in very shallow water.
  6. Seaworthiness – The S4 excels in going through waves, and it reacts extremely well to other boats’ wakes. Such performance isn’t typical for a small or even medium size skiff, and it can be found only in bigger models.
  7. Price to Performance – The S4 may not be the least expensive micro skiff on the market, since the solitude skiff is offered for less, but in terms of price to performance the S4 is in a league of its own, especially considering the fact that it is a trailer free boat, and trailers cost money.

Conclusion?

As shown here, the S4 barely fits in the micro skiff class, and it deserves to be in a class of its own. However, a class of boats with just one boat model in it is not a practical tool for classification, or for anything else. The S4 is somehow comparable to the Wavewalk 700 (W700), but again, a class of boats with just two boat models in it could be acceptable in design terms, but it would not serve its purpose in marketing terms.

And this article didn’t even touch the question of the S4 classification as a kayak…

 

The kayak for tall and heavy (“big”) people

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?

Tall people-

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.

A compressed abdomen makes it harder to breath, and with a compressed behind and lower spine come an exacerbation of the typical kayaking back pain symptoms.

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:
