We used the S4 at my latest veterans event and it was a hit.
We used the S4 at my latest veterans event and it was a hit.
I usually keep my Wavewalk S4 on my dock so I can use it right there. But sometimes, we like to explore other areas. I don’t have a truck to transport it, so I decided to convert an old sailboat trailer into a Wavewalk S4 trailer.
All it took was some treated 2×6 and 2×4 boards, some U-bolts, and some ceramic deck screws.
I started with the trailer for a [brand name] sailing catamaran that I don’t use.
I’ve never trailered that boat.
The first step was to attach two 2×6 boards each with a U-bolt on the front and the back. On top of those, I screwed five 2×6 cross-boards so they support the boat from underneath all the way from front to back. Then I added 2×4 boards on both of the outside edges to provide an outer groove for the S4 to sit inside. A set of rollers from the sailboat trailer act as guides to align the inner hull of the S4.
The result? A very light but stable platform to pull my Wavewalk S4. When we get to the boat ramp we just back it down the ramp and the S4 slides off the trailer with an easy push. You should have seen the faces of the big boat owners at the ramp when I launched my boat with one finger!
The key to trailering the boat is to make sure it is tied down securely in the front and the back so that it doesn’t slide forward or backwards. I also have two lines over the top of the boat to hold it down, but be
careful not to over-tighten these and compress the hull. Also, remember to tilt the motor up if you have one so it doesn’t hit the ground as you trailer it.
Having a homemade trailer can extend the range of your Wavewalk adventures and save the hassle of loading it in or on top of your vehicle. All it takes is a used trailer and some treated boards!
This short movie shows Captain Larry Jarboe driving his S4 kayak skiff powered by a 9.8 HP Tohatsu outboard motor with a 6’3″ 260 lbs passenger on board, in a narrow and winding mangrove creek. The total payload carried by his S4 is over 500 lbs.
The S4 is perfectly stable and maneuvers easily despite the high speed and heavy load.
Larry is driving seated side-saddle, dinghy style, with both feet in the left hull and facing sideways, and his passenger rides the saddle PWC style, with a foot in each hull, and facing forward.

I got my Wavewalk S4 from capt Larry and love it.
I am a former Navy SEAL and have ridden many hours in inflatable boats, so I appreciate the stability and comfort of my S4, and I volunteered to be a local demo agent for it.
I rigged my Wavewalk for lobster fishing, and I am currently rigging it for diving.
Typically, kayak and boat reviews are written by clients who mean what they say, but aren’t necessarily professional, or by people that the manufacturer paid to review their product. The latter reviews are not objective to begin with, and in many cases they are not even professional. Designers seldom publish reviews of the kayak or boat that they designed.
Other reviews commonly found on the web are fake, and they were written by individuals who are affiliated with the manufacturer of the reviewed product (fake positive reviews) or with their competitors (fake negative reviews). Some fake reviews that appear on websites that offer people to publish kayak and boat reviews appear to have been written under an alias by the website owners, probably in order to make their website look more popular than it is in reality.
Wavewalk does not pay people to review its products, and it does not post anonymous reviews on websites that offer to do so to anyone who can come up with an alias and a few sentences. We think that such websites have a low credibility from the beginning, and their credibility has declined over the years, as people who read the reviews that these websites feature have become used to apply critical reading, and common sense.
We decided to publish our own review of the Wavewalk S4 after it’s been out there for nearly a year, which is enough time for us to see what it can do, and what our clients think of it (Read S4 clients’ reviews » ). In this review of the S4, we try to compare our initial plans for this boat to what it does in reality, and we also try to look into the future, as much as possible, and see what it could still do.
Many Wavewalk clients are interested in the design of kayak and small boats, and we think that such people may have a particular interest in reading this review.
It takes close to a hundred thousand dollars to produce a new product such as the S4 in terms of time and money invested in the design and manufacturing of a capital tooling (rotational mold) for it. Once the product is out there, it takes more time and money to test and promote it.
This means that before a small company decides to invest in the development of such a product, it needs to make sure that it has a good reason to do so, and preferably more than one good reason.
Before we started defining the requirements from a future Wavewalk product, we looked at existing products in various markets, including our own W700 that we had launched back in August of 2015 –
From the moment we launched it, the W700 became an immediate, remarkable success, both as a tandem kayak for touring and fishing (and hunting, photography, etc..) and as an ultralight portable motorboat / microskiff. This success gave us the motivation and the funds to take the Wavewalk concept to the next level. Our clients loved to motorize their W700, but few were willing to give up paddling altogether, and this convinced us that paddling was important, so we decided that our next product, namely the S4, will be more of a high performance, fast and seaworthy motorboat with a bigger payload capacity, but it would still offer good paddling capabilities as a kayak and a canoe. Another thing that our clients love in their W700 was the ability to car-top it without a problem, and this meant that the next Wavewalk had to be a car-top boat too.
Before we started to design the S4, we looked at different products in a number of markets, and tried to identify unfulfilled needs as well as opportunities for our new product –
A new boat often starts as ideas that the designer’s mind generates in reaction to external stimuli, such as impressions, challenges or compliments. The general idea and major challenge with the S4 was to create a boat like which the world has never seen before, and no one had thought would be possible. We knew the Wavewalk invention would guarantee that whichever design we choose for a Wavewalk boat that’s wider than the W700, it would automatically become the world’s most stable kayak, as well as the world’s most stable boat for its size. Within this framework, we still had a lot of things to think about, including –
Launching the product, and testing it – We launched the S4 in May of 2017, and since then, the S4 has kept growing in terms of proving what it’s capable of doing. We were pleased to see that a 214 lbs guy could easily stand with both feet in one of the S4 hulls, and turn around, without flipping the boat, and without even making it tilt by much. We were more pleased to see three adult paddlers standing in it and paddling without any problem. But we were astonished to see three full-size guys fish standing out of a motorized S4, with one of them landing a good size fish in the boat. Many thanks to Mike Silva for these amazing pictures!
We loved watching the videos that showed the S4 driven through lily pads, propelled with a surface drive powered by a 6.5 HP motor. But driving an S4 powered by a 9.8 HP going at full throttle was a blast, and it was such a smooth drive that it certainly opened the door for testing it with more powerful motors, as a couple S4 owners already said they will do.
Multi-boat configuration – Another innovative and inspiring development was Captain Larry Jarboe’s S4x3 multi-boat, composed of a motorized S4 hip-towing (side towing) an S4 on each side, and thus allowing the driver to transport a much larger number of passengers, in full comfort, and with the stability of a large size pontoon boat. Captain Jarboe uses the S4x3 multi-boat for his guided diving tours in Key Largo.
Big boats, seaworthiness, maintenance, etc. – Interestingly, the S4 is already used, successfully, as an alternative to full-size skiffs. Its users prefer their S4s to the large size boats that they had previously used because of its easy launching, shallow draft, and better seaworthiness in choppy water. Indeed, we found that if you happen to get seasick in a boat going or anchored in the chop, riding the saddle of an S4 would instantly cure you, whether you’re driving it or just taking a ride in it as a passenger. The S4 is practically immune to other motorboats’ wakes, including big and fast boats traveling at a short distance from it, and this is not an exaggeration but an accurate description of a pleasant reality. And the S4 works as a paddle craft, so that it’s practically impossible to get stranded at low tide when you fish from it. Another reason to prefer the S4 over a full size boat is that it’s totally maintenance free, and if you’ve never owned a boat, it would probably be hard for you to appreciate the importance of this fact.
Spray shield – It turned out that when one person drives the S4, even at high speed, and even in the chop, the hulls and front deck deflect much of the spray that’s generated when they hit waves. However, when a passenger sits in front of the S4 driver, their weight lowers the bow, and it tends to generate more spray when it hits waves. And this is when a spray shield can still be useful.
A new type of watercraft – The S4 has already shown that it’s a new type of watercraft with a performance envelope that sets it apart from all boats of similar size. But it still has room to grow, in the sense of showing that it’s capable of more. We’ve already mentioned more exploits with mud motors, as well as bigger and more powerful outboard motors. We’d also like to show how a sculling (shell rowing) coach from Massachusetts uses his S4 as a coaching boat because he’s found that it generates a much smaller wake than other boats of similar size, and a small wake is the name of the game when coaching this sport is concerned.
On the other side of the performance spectrum, we should find an opportunity to run the S4 in rough seas with inflatable flotation modules attached to its sides, RHIB style (RHIB stands for rigid hull inflatable boat).
And on a completely different angle, we’re waiting for clients who use their S4 in whitewater, as a guide boat and a raft, to send us pictures too.
Extreme efficiency with a 1:6 weight to load ratio (payload ratio) – The S4 weighs a little less than 100 lbs without a motor, and it can carry a payload of over 650 lbs including a motor. This is a solid 1:6 weight to load ratio that shows how efficient the S4 design is.
We could have talked more about our S4, but with 3,700 words, this review is getting too long for a reasonable person to read – Thank you for making it this far 🙂
