Magnus has been fishing the SF bay from his S4 since 2018, and he will be happy to show it to you if you’re seriously considering ordering one for yourself. To schedule an appointment with Magnus, call/text him at 415 568-6288
I finally got a chance to take the S4 out and test it on the water. It’s working beautifully with the Honda 2.3 engine. We actually have 3 people seat in it comfortably and both paddling and using the motor works quite well.
We launched the S4 at a rocky beach, and dragging the S4 over the sharp rocks caused some scratches on the bottom of the S4. This is a minor issue, and I’ve decided not to worry about it 🙂
Overall, I am very satisfied with the S4. Great Kayak and I can’t wait to show it off to my friends on the next fishing trip!
I was too busy with the S4. There aren’t any pics while the S4 is cruising in the water since all three of us were in the S4 and didn’t have anyone to take pictures from the shore.
Here are some of the pics my friend took on the beach –

UPDATE – August 2018
I have been taking the S4 to many fishing and clamming trips and it’s working great and impressed a lot of people!
A couple times we encountered bigger than expected swells so if it wasn’t the S4, we would have tipped over for sure. Most of the people who ride on it confirmed the S4 is the most stable kayak compared to everything they have seen.
One small thing I noticed is that when we have close to max load on the S4 in the bigger waves, the water splashes front and gets in the cockpit, so I think the splash shield may help with this.
This is a movie that Captain Larry Jarboe of Wavewalk Adventures in Key Largo, FL shot while driving a Wavewalk S4 powered by a 5 HP 4-cycle Tohatsu outboard motor.
The second S4 featuring in this movie is Larry’s White Knight, the S4 workhorse that he uses daily for demos and guided fishing or diving tours, as well as a pleasure boat.
Larry outfitted the White Knight with a 9.8 HP 2-cycle Tohatsu outboard that propels it on flat water at 17 mph, which is currently the world speed record for kayaks*Â that Larry holds.
The guy seen in this video driving this fast boat (kayak…) is the guy who designs Wavewalk’s products, for better and for worse 😉
* Not every small vessel that’s compared to a kayak for marketing purpose is a US Coast Guard (USCG) designated kayak.
All Wavewalk’s patented catamaran kayaks and kayak-skiffs are officially designated as kayaks.
“Kayak”??… This is likely to be the last thing that comes to mind of anyone watching this movie, but indeed, the S4, like all Wavewalk’s patented catamaran boats, is officially designated as a kayak, not just because of its light weight (98 lbs) and high performance as a paddle craft, but mainly thanks to certain design features required by law.
Skiff?… The kind of performance seen in this movie is not what you’d expect from a skiff or skiff by name.
Wavewalk likes to bring forward the S4’s performance as a skiff, namely a fishing boat for flat water, but there’s no flat water to be seen in this offshore movie… far from that!
PWC?… Such comparison would have been more appropriate if we used wheel steering instead of direct steering with the tiller, and possibly an even more powerful motor than the 9.8 HP Tohatsu that features in this movie. Nevertheless, the movie conveys some of the action and excitement associated with Personal Watercraft (PWC), sometimes referred to as jet-skis.
PWC stability at high speed
This video shows the Wavewalk S4 powered by a 9.8 HP Tohatsu outboard motor, driven at full throttle, offshore, in choppy water and waves.
It demonstrates a performance level that’s new in the world of small boats and watercraft, including both unrivaled speed and stability that enables stand-up driving and wave-hopping that one expects to find only in Personal Watercraft (PWC).
Perfect balancing and ergonomic saddle seat
The Wavewalk design and PWC have one feature in common, which is their similar saddle seats that deliver the best balancing capabilities to the driver and passengers. But the advantage of the saddle seat doesn’t end there – The saddle also allows the driver and passengers’ legs to act naturally as powerful and effective shock absorbers that protect their backs from the unwanted impact of the constant leaps and bounds, and high speed clashes with waves.
Being officially designated as a kayak, the S4 delivers these capabilities in a paddling mode too, although at much lower speeds…
A most seaworthy small boat
The performance seen in this video is not the kind of performance that flat-bottomed boats such as Jon boats or skiffs can deliver. The S4 is seaworthy, while these traditional small fishing boats aren’t.
What cannot be well perceived from watching this movie is the fact that the S4 is dry too – Frontal clashes with waves do not let water into its hulls, and the only time when spray gets in is when the boat is hits a wave with its broadside. Even then, very little water gets inside.
Shooting this video
The cameraman was Captain Larry Jarboe, standing on the deck of his fishing boat, the Line Dancer, that was anchored in the same choppy waters as the S4 is seen going in. The Line Dancer was constantly bouncing and tilting, which made it particularly difficult to shoot video of another, distant and fast moving small boat.
Larry used a Nikon Coolpix 900 digital camera with a powerful x83 optical zoom lens, in an auto-focus mode, but since placing this camera on a tripod would have been useless under these hectic conditions, Larry’s sea legs were the decisive factor that helped produce the video footage for this movie.
The White Knight – Larry’s workhorse S4
The boat in this movie is Larry’s personal S4, dubbed the White Knight. Larry offers fishing and diving tours in Key Largo, and it is this boat that he uses in these trips, and on a daily basis. The White Knight features a base for a diving ladder at the bow, and foam boards on its sides, since Larry sometimes uses it to side-tow two other S4s,each attached to a different side of the White Knight.
The White Knight is powered by a 9.8 HP 2-cycle Tohatsu outboard motor, and Larry recently clocked 17 mph with it, which is a world speed record for kayaks.
Driving the S4
The S4 operator in this movie is 56 years old, and not in great shape. An athletic driver half his age would have probably driven the S4 more aggressively and spectacularly, but that tired-looking, gray haired driver adds a feeling of reality to the video, or so we hope…
Captain Larry Jarboe from Wavewalk Adventures in Key Largo, Florida, drives his “White Knight” workhorse S4 cat-skiff powered by a 9.8 HP 2-cycle Tohatsu outboard motor, outfitted with a 9″ pitch propeller.
Larry easily gets to a 17 mph speed, which is probably a world record for vessels that are officially designated as kayaks, such as the S4.
He drives sitting in the side-saddle position, similarly to the way that he’s been driving dinghies and other small boats for decades – No stability problems, and no control problems, even in the chop. Most people who drive the S4 and other Wavewalk kayaks / boats do it in the riding position, with a leg on each side of the saddle seat, similarly to the way that Personal Watercraft (PWC a.k.a. jet-ski) drivers operate these vessels.
Generally, 2-stroke outboard motors are lighter than comparable 4-stroke outboards, which makes them more portable.
9″ is the highest pitch for propellers that fit this motor. A propeller with a higher pitch would have probably added some speed to Larry’s record. In any case, 17 mph falls within the upper range of speeds achieved by small, lightweight boats with propellers of such pitch.
Practically speaking, this performance coupled with the S4’s capability to carry on board up to three anglers and their fishing gear, puts it on par with Jon boats, skiffs, and even some bass boats.
The S4 is an ultralight car-top boat that can be launched and carried anywhere, as well as paddled in extremely shallow water, and it is most seaworthy. These facts offer its users an advantage that neither conventional nor new boats do.
Note that Larry is a most experience boat driver, and driving such a small craft at such high speeds requires skills that not anyone has. This is to say that we do not recommend such powerful motors for the S4.
