A boat is a small watercraft. Motorized fishing boats are popular among recreational anglers. Kayaks are sometimes referred to as small, personal boats.

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.

Wavewalk 700 review by Canadian fishing & hunting guide

By Russ Popp

 

Winnipeg, Manitoba, Canada

I am very pleased about the Wavewalk 700 .
It is a very easy craft to get in and out of.
It is a very stable craft for older people to feel safe in.
Easy to transport.
As an retired Canadian Outfitter and Guide for fishing and hunting, there is definite use and purpose for the Wavewalk in my outdoor activities, leaving the other four canoes, three kayaks and one twelve foot aluminum boat at home that I already had.

Last fall I used it for fishing and goose hunting with my gun dog.

I got my wife out, in the Wavewalk, this last fall –

 

 

We have some great videos with a go-pro but can’t seem to post them on you tube for some reason?

The ice believe it or not is still on the lakes this spring.
I was ice fishing for Lake Trout three weeks ago.

Lots of work to do this spring.
Tear down the old cabin (Had it from 1966, until now), and build a four seasons home in the bush, one hundred miles from where we are now living.
Will have to sneak in some kind of time, somewhere for the Wavewalk, but don’t know where this spring?

Curious fox…

 

The only thing I am having trouble with the Wavewalk is, that here in Canada, the plumbing pipe sizes don’t match the American plumbing pipe size holes, in the seat to make accessories for the craft at this time.
I am sure at some point in time, after building our home in the bush, I will find away to get the right size plastic pipe, and stand attachments for bolting onto the plywood to make all my ideas I have in mind.
Too bad I am retired now from Outfitting American clients, because they could have brought some pipe and attachments up with them, when they came up hunting and fishing with me.

Shooting a ringneck duck out of a Wavewalk 700

By Chris Henderson

Fishing Kayaks of Gig Harbor

 

Well for the last month I have suffered through a horrible pinched nerve in my neck. This has prevented me from being out in the Wavewalk where I try and get at least 3-4 times a month during the fishing and hunting seasons. Basically every month but Feb. and the beginning of March which is effectively known as remodel season. After working diligently on rehab I was able to return to duck hunting this last week. The Wavewalks are our go to boat when it comes to hunting. We can put 3 dozen deeks, shotgun, camo net, hunting box, thermos and our selves in a W700 and paddle it anywhere we need to go. Then it not only serves as transportation but also as the boat for retrieving. That is where the stability is so important. You sometimes have to dispatch cripples (shoot them) from the kayak. As the video shows this can sometimes get a bit sporty. Wavewalk handles it fine.

The video is a bit of fun we had with a GoPro. If you don’t like hunting you won’t want to watch it. We enjoy the sport of duck hunting and the wonderful food it provides.

We were having a hard time keeping those ringnecks on the water.  They are tough birds.  We would smack them and then by the time we could get out to them they would recover and fly off!  Diver ducks are really tough birds.  Probably because they have very thick down and feathers to protect from the water.
We had a great time.

Good to be back in the saddle again.

Coming soon: The Wavewalk® 4 Series

Is it a boat? a skiff? a tandem fishing kayak? a two-person canoe? a hunting boat? something else? …
The answer is yes.
More specifically, the answer depends a lot on what you want to do with it, and where you want to do it. This boat can do a lot, and it can do it like no other boat can.
