First impression of the S4

By Joe Stauder

HBBCO Fishing Kayaks, PA

 

Wavewalk did it again! I thought the 700 was the best there could be, until we got our first S4, what a great craft to motorize.

In my opinion, this craft is the Ultimate in small craft versatility. It lends itself to any kind of propulsion, paddles, electric trolling motor, and especially a small gas outboard. This thing handles like a dream. She wants to track nice and straight until you turn her, then she can turn on a dime. Now I truly didn’t get a lot of time on the water with her, because we sold her already. Bob wanted her so bad he drove up to PA. from West Virginia to get her. He is in love with his new craft, and the custom rigging we did for him.

White S4 arrived

By Jack Snapp

Texas

 

Took off from work early to get my S4 on the water the first time.
Arrived at boat launch and five minutes later was in the water. That’s at first! And without getting wet!   🙂
Easy to paddle seated or standing. Only minor issue was tracking in straight line up-river while coasting. Not an issue going down-river.
Shouldn’t be a problem with two people.
Can’t wait to motorize.
Woo Hoo!!!!!

Oh, love the storage. Can pack it at home and then straight in the water. Same when coming out of water. Not like a SOT kayak where you loading/unloading your gear to transport.
That’s a huge plus for me.

 

 

 

 

 


 

Update I

Spent 3 1/2 hours on Lake Dunlap this morning.
Beautiful day. Got lots of stares. Almost constant paddling, seated and standing.
So comfortable!
Could have gone much longer.

 


Update II

Had a blast on the water on Sunday. Just need to get used to steering behind me. S4 handled perfectly, even over the wakes from other boats and jet skis. Got a few stares and thumbs up. Plenty of power from the 6hp Tohatsu to get to my fishing spots quickly. Then, I can tilt the motor up and paddle/pole around the skinny water.


Update III

Got my S4 up to 13 mph, but it runs consistently at 11 mph at open throttle. Just me and light gear on board. Wonder if others are experiencing the same, or better. Love to jump the wakes of jet skis and other boats. But, normally not at top speed. It could easily handle a larger motor.
 

Jon Boat Stability vs. Wavewalk® S4

Are Jon Boats Stable?

 

If you ask whether Jon Boats are stable, some people would say that they are, and others would warn you to stay away from them because they are tippy and unreliable. Their answer would depend on what they understand by ‘Stability’, what kind of Jon boat they see in their mind, and in what kind of water they see it being used, and these are often based on personal experience.

Is there a stability difference between a Jon boat and a skiff?

Both skiffs and Jon boats are flat bottom lightweight boats that differ in certain hull details, materials used in their construction, and deck structures.
Both are designed to offer as much stability as possible for a small mono-hull boat going on flat water, and as such they are stabler than wide canoes and kayaks of the same length and width.
Foot for foot and inch for inch, we don’t think there are major differences between Jon boats and skiffs in terms of the stability they offer. In other words, a Jon boat and a skiff of the same size, namely both length and width, can be expected to be about as stable as each other.

The twin-hull (“catamaran”) Wavewalk S4 is the world’s most stable portable boat. It is more stable than many Jon boats that feature a bigger hull, as shown in these photos of three fishermen fishing standing in it –

Who Uses Jon Boats, and Where?

Jon boats are small fishing boats that are popular among inland fishermen who fish ponds, small lakes, marshes, and slow moving rivers, namely flat water that’s usually well protected from wind, waves, and preferably from fast motorboats that generate big wakes. These anglers may fish alone, but typically they fish in crews of two. Bigger Jon boats can be used in bigger lakes and rivers.

Factors in Jon Boats’ Stability

Structure, size and passengers

A typical Jon boat features a flat bottom designed to make it draft as little as possible, and thus work well in shallow water, while other Jon boats feature a bottom that’s partially V shaped (sometimes referred to as “Semi-V”) that drafts a little more but offers better performance in choppy water. This V shape should not be confounded with the more seaworthy Deep-V design.
Jon boats can vary in width (Beam) from less than 3 ft to over twice as much, and this difference results in big variations in their stability, in this case initial (primary) stability, sometimes dubbed reserve stability.

When watercraft as small as Jon boats are concerned, passengers are typically the heaviest things on board, which is why passengers’ location and movements can greatly affect the boat’s stability.

Narrow-beam Jon boats are notoriously unstable, especially with a crew of two on board. Their instability can be felt even when they are used for fishing ponds and small lakes, where they are expected to perform at their best. Reading articles about Jon boat stability and user testimonials on this subject could lead the reader to the conclusion that any Jon boat that’s narrower than 48″ might not be stable enough for a tandem crew, and starting from this size, Jon boats get sufficiently stable, especially longer models. Another factor that affects a Jon boat’s stability is its length, since it acts as an enhancement to its width – A longer Jon boat is more stable than a shorter Jon boat of identical width (Beam).

External factors

External factors may destabilize a Jon boat as well, or at least destabilize the passengers on board – Such factors can be wind, waves and other boats’ wakes that hit the boat, especially on its sides (lateral waves).

Size matters, but it may not be enough

We found the following instructions for Calculating a Boat’s Capacity to Carry a Number of Passengers on a boating education website:
On boats less than 20 feet long, the following rule of thumb can be used to calculate the number of persons (weighing 150 lbs each) the boat can carry safely in fair weather and calm water conditions:
Number of passengers = boat length in ft x boat width in ft : 15
Example for a good size Jon boat or skiff: 15 ft x 4 ft = 60, and 60:15 = 4 passengers

However, the above formula seems outdated in view of the fact that these days the average adult US female weighs 160 lbs, and the average adult US male weighs 200 lbs.
Therefore, to calculate the number of adult passengers in a Jon boat, we suggest to use the same formula and divide the result by 20 instead of by 15.
Example for the same Jon boat or skiff: 15 ft x 4 ft = 60, and 60:20 = 3 passengers

Can the 13 ft long and 38″ wide Wavewalk S4 carry 3 passengers on board?
The answer is yes, in fair weather and calm water conditions:

Balancing capability

When small craft are concerned, the boat’s own stability plays an important role in the overall stability of the combined boat and crew, but the passengers’ ability to balance themselves effectively is critical as well, which is to say that a wider Jon boat may not necessarily offer better means for its crew to balance themselves effectively –
Jon boats often feature rudimentary bench-like seats that are similar to ones found in canoes and dinghies, or high swivel seats such as can be found in bass boats. Neither types of seats are optimized for supporting the user’s balancing efforts, and they’re not very good in keeping their user anchored to their place and in full  control of their body’s center of gravity (CG).
This ergonomic deficiency exposes a Jon boat’s passenger to unexpected lateral (side) motion, as well as vertical motion, whether such motion is the result of an external force such as a wave or another boat’s wake, the movement of another passenger on board, or even the strong reaction of the boat to that passenger’s own movements.  More specifically, people on board a Jon boat can have a hard time finding their footing and balancing themselves intuitively, comfortably and effortlessly, and from the moment they lose their footing and balance, their own weight can act as an additional destabilizing factor that may tip the boat over, send its passengers overboard, and in some cases even overturn the boat.

A Jon boat of a smaller size works better as a fishing boat for one angler than it does for a crew of two.

Directional stability and lateral stability

Typically, Jon boats are motorized, and the flat bottomed ones can be easily deflected from their course as well as destabilized when going in lateral waves, especially at higher speeds. In such cases, the deficiency in a Jon boat’s lateral stability can become more problematic by the lack of good directional stability (tracking capability) that characterizes such boats, in particular ones that feature a flat bottom. People who use such boats are quick to head back home as soon as the wind picks up.
Jon boats with a V-shaped hull do better in waves and wind, thanks to the fact that they have some capability to go through waves and not necessarily on top of them, which isn’t the case with flat bottomed Jon boats that are essentially designed for use on flat water only.
This said, although Jon boats are not considered to be seaworthy craft, the bigger ones are sufficiently stable to offer a good experience to a crew of two or more anglers who fish inland, preferably in calm and protected waters, and away from fast motorboat traffic.

Stability: Jon Boats vs. Wavewalk® Series 4 (S4)

 

A detailed stability comparison between Jon boats and the Wavewalk® S4 is almost impossible to complete, because Jon boats vary so much in size and structure, and they can range from a flat bottomed, 32″ wide and 10 ft long (1032) boat to a V-bottom 72″ wide and 18 ft long one (1872), which can be assigned to another class of boats.

The Wavewalk form presents two main stability advantages:
The first comes from the fact that all the Wavewalk’s buoyancy is distributed as far as possible from the boat’s center line, where this buoyancy works more effectively to support lateral changes, whether such changes are external of generated on board.
The second advantage is the Wavewalk’s Personal Watercraft saddle seat that offers the passengers who ride it optimal, easy and intuitive means to balance themselves. This advantage is critical in view of the fact that the passengers’ total weight can be as big the the Jon boat’s weight, and it often exceeds this weight. For example, in the photo above, the passengers’ aggregated weight exceeds the S4’s weight by a factor of 5:1.

So, in order to avoid tedious detailed stability comparisons, let us simplify things and state that in general, the bigger models in the Jon boat class (over 54″ beam) are more stable than the S4, the smaller Jon boat models (less than 48″ beam) are less stable, and as for the the midsize models (48″ to 54″) the answer would depend on parameters such as their length (longer is more stable), and whether they feature a flat bottom or a V-shaped bottom, as discussed in the previous section of this article.

Bottom line: Compared to the traditional Jon boat design, the Wavewalk S4’s form and improved ergonomics add stability which is the equivalent of about 1 ft in width.

Portability and paddling capacity

More specifically, the Wavewalk® S4 is stabler than any car-topper namely portable Jon boat. Which is to say that if you’re looking for a Jon boat that’s more stable than the S4, you must take into consideration transporting and storing it on a trailer, as well as limitations in launching it, namely being dependent on launch ramps that come with trailer boats.

In addition, the Wavewalk® S4 is more stable than any Jon boat that can be propelled by means of paddling, whether it’s with dual blade (kayak) paddles or single-blade (canoe) paddles. This fact is particularly meaningful when very shallow water (‘skinny water’) fisheries are concerned, and no-motor zones (NMZ).

 

 

Seaworthiness

Generally speaking, Jon boats are not considered as being seaworthy, while Wavewalk® boats are more seaworthy thanks to their good  tracking capability and advanced ergonomics. These two factors allow for high performance when dealing with choppy water, which is why the S4 punches above its weight in terms of seaworthiness.

 

 

 

Payload

Small craft are penalized for their size in several ways, and one of them is their sensitivity to carrying more weight on board, which makes them slower and less stable. This is true for all boat designs, including Jon boat and Wavewalk. Therefore if you’re looking for stability for a larger crew of heavier people, say two big and heavy guys or more, your best bet is a very large Jon boat or skiff, that is 6 ft or more in width, and over 16 ft in length, and preferably with a V shaped bottom, so that you could drive it at higher speed. Two large size fishermen can go in an S4 and have a great time traveling and fishing for an entire day without experiencing any stability problem, even standing up, but they would not necessarily be able to go at speeds as high as a large size Jon boat or skiff offers.

Paddling in Strong Wind

Paddling and Tracking in Strong wind

Tracking is the main problem that paddlers need to overcome when paddling in strong wind.
Wavewalk paddlers usually report excellent performance of their boats under wind, since catamarans tracks well, generally, and also thanks to the fact that it offers multiple means for power-paddling, as well as for counter-affecting the wind.
Since 2004, thousands of people have been paddling Wavewalk kayaks from the 300, 500 and 700 series, and none of these paddlers outfitted their Wavewalk with a rudder – that cumbersome device that has become an integral part of all other types of high-end kayaks used for touring and fishing.

Here are some tips that can improve your Wavewalk kayak’s performance when you’re paddling in strong wind:

1. Paddle only in the Riding Position, which is the optimal posture for power and balancing, and lean a bit forward, with your knees lower than your hips – That would give you extra power.

2. Paddle from the middle of the cockpit, as much as possible –

  • If you paddle from its rear it would raise your W kayak’s bow and expose it to the wind, and the boat will turn away from the wind.
  • If you paddle from the front of the cockpit, the stern will go up, and the kayak will turn into the wind.

3. Lean your W kayak into the wind – That would make it harder for it to affect the course of your W kayak.

4. Apply short J strokes on the side from which the wind is blowing, and more powerful strokes on the lee side (the sheltered side) – That would help you track. You may even hold the paddle not from its middle, so that you can apply longer strokes on the lee side.

6. Any object protruding from the deck is exposed to the wind, and therefore generates additional drag – Detach the spray shield if you have one attached, dismount deck mounted rod holders, and store your fishing rods inside the hulls whenever possible. A milk crate would act as a small sail that’s controlled by the wind, so you’d better avoid using one altogether.

7. Keep paddling in a steady pace and a straight course – This is not about one-time corrections, but about minimizing your effort and getting there. Precision and efficiency are as important as power.

8. IMPORTANT – Remember that you can easily move fore and aft along the Wavewalk’s saddle, and by doing so control the angle in which your W kayak will point relatively to the direction from which the wind blows: Paddling from a forward position will tend to point the kayak’s bow into the wind, and paddling from a backward position will tend to point the bow away from the wind.
By applying small changes to your own location on the saddle, you can minimize the wind’s unwanted effect on your Wavewalk, and keep it tracking with little effort.

A day on Lake Ouachita

Scot and Mary Alice VanHorn

Arkansas

We absolutely love the Wavewalk 700! It’s everything we were promised it would be!
We’ve had it out a couple of times due to busy schedules but I’ve never enjoyed kayaking as much as I have with this kayak! It tracks beautifully just as promised, and so comfortable to sit in for long periods of time!
We absolutely love it and recommend it to everyone we talk to!
It’s also a dream to transport. It’s so light and easy to put on top of the truck, strap it down and away we go!
Thank you for such a beauty of a vessel! Love it!

Here’s a couple of pics of the kayak and Scot out on the lake. Loved every minute of it! Thanks!
