Interesting story on my little 2 hp Yamaha I use on the boat. I know I haven’t used the motor in at least two years, maybe longer. I pulled it out a few weeks ago. The gas tank was full of non leaded gas that has had marine stabilizer in it. I didn’t really think it would run well but I put it in a tank and gave it a pull. The little bugger started on the first pull. I used that tank for my trip below and it never gave me one problem. I was pretty surprised.
Now for the fishing. This week I decided I needed to make the two hour trip from St. Augustine to the upper St. Johns River for the annual Shad run. Actually upriver is south for the St. Johns, as it is one of a handful of rivers that runs from south to north in the US. The Shad migrate from the ocean to the headwaters of the St. Johns to breed each year. They are fun to catch on light fly gear and are tenacious fighters. I decided I didn’t want to bother hauling my skiff and the hassle of packing everything so I popped the W500 in the back of my Ridgeline, threw the motor in along with some fly gear and was on my for a little fly fishing therapy, launching at the Jolly Gator Fish camp. I didn’t exactly kill them but caught a couple to satisfy my itch. I also hooked two of the larger Crappie, and Bream (Sunfish to you Yankees) that I have ever landed. So, not a stellar day but at least fish were had. The area is very unique. The river meanders through a large expanse of grass and marsh lands that are used for grazing horses and cows. Plenty of wildlife from herons, egrets, white pelicans, otters, gators, wild pigs, and other creatures. The river also contains quite a variety of fish to catch, including hybrid striper bass. I usually get one trip in a year for the Shad run, though this year I may need one more to see if I can do a little better in the catching department.
I created a custom trailer for “The Dub” [Wavewalk S4] out of an old sailboat trailer. We took it to a local boat ramp and motored about an hour through the marshes to a barrier island to go shelling. Made it there and back in fine style.
We got some funny looks from people watching us go by and watching me launch the boat with one finger!
Today I was able to do my first test drive of the Wavewalk S4 with a mud motor!
As a duck hunter the potential for the S4 is incredible. Couple that with a mud motor and you can access places that others cannot go. I hunt tidal mud flats where traditional boat motors are difficult to use due to the changing tides (water depth) as well as the sand bars that constantly shift. The mud motor allows operation in very shallow water and lets me get over those sand bars. Other duck hunters hunt in flooded timber where the logs eat propellers for lunch and occasionally eat whole lower units. The mud motor is the only way to travel safely in those kind of swamps. That is why putting a mud motor on the S4 is like combining peanut butter and chocolate. This was my very first run, so I have a lot to learn about operating this kind of motor.
There are a lot of different styles of mud motors out there and the cost can be very prohibitive. But I found a kit which is created by Mud-skipper called the Twister. Rather than a straight shaft it has a curved shaft. At first I was concerned that due to this the turning radius of the boat would be dramatically effected. As it turns out that fear was unwarranted. The two hulls actually keep you from turning too sharp which could cause you to overturn considering the nature of how the motor turns. The 6.5 hp was plenty of horse power and I cavitated way before I ran out of power.
Lots of experimenting to do to get it all dialed in but it was a great first test run.
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 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:

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).
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.
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.
This is the first duck hunting season we have used both the W500 and the W700 as duck hunting boats and they are doing great! It would be easy to put a blind on it (we have one all designed) but we mostly use the boats for transportation. The area we hunt is tidal mud flat. So the cover is minimal, actually non-existent. We sit on beach chairs in the mud and pretend to be a log. However, where the Wavewalk’s shine is in getting us to the spot. We paddle for 1.5miles over water that runs from 6 inches to 20 feet, with lots of logs, mussel beds, and all sorts of things that are a constant danger to motorized boats. In addition once we get to the spot we will be on the move the whole day. For instance yesterday’s tide went from 1.9 feet at 3 am to a 14.4 feet at 9:54 am and then back to 4.9 feet at 4:43 pm. We hunted from 5 am until about 4:00pm. So we saw and moved through most of that. We start on a mud flat, retreat to a log and end up back on the mud flat. It is work intensive hunting! The Wavewalk makes it possible for a couple of reasons. One it handles the current and wind with great proficiency. Tidal current is a constant, one direction or the other. In addition, this is the mouth of the Nisqually river, so you have a lot of water coming from there. And it seems there is always a wind and often with accompanying waves. With the Wavewalk you are able to paddle through all of this and feel secure knowing that you can handle it. It is not just a convenience it is a safety issue. We are paddling in water that has a constant temperature year round of 54 degrees, but the air temperature yesterday started at 24 degrees raising to a balmy 36, and oh yeah we paddle to the spot in the dark. If you get in trouble you are on your own. Often people ask me why not put a motor on it? For one simple reason; MUD! We move about 200 yards between low and high tides and then back again. During that we are dragging our boats forward and backward with the tide. We drag them in mud that can actually be a danger if you get stuck. The Coast guard had to airlift rescue a duck hunter from this marsh already this year who was stuck in the mud. Dragging 60 or 80 lbs of boat through mud is a challenge, but if you added the weight of a motor it would become impractical. The second reason the Wavewalks are so perfect for this hunting is the sheer storage. In the W700 I am able to transport 36 decoys, camo blankets for the boat and hunters, shotgun, lawn chair, hunting bucket, thermos, and myself with ease. In fact there is so much room in W700’s it hauls all of the decoys!
Yesterday I was able to take a friend who had never hunted in this way and put him in a Wavewalk for the first time. He is a big fellow so I put him in the W700. With very little effort he was comfortably and efficiently paddling, and we had a great hunt.
These boats are not just for fishing but they make great duck boats as well. So far this duck season the Wavewalks have gotten us 63 ducks, and we still have January to go!
Loving the Wavewalk as a great duck boat! Enjoy a few pictures of the season!
