Wavewalk S4 “kayak” with 9.8 HP Tohatsu outboard motor, offshore, in waves, at full throttle

Kayak, skiff, or PWC?

“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…

 

10 good reasons to motorize your kayak

Wavewalk is the world leader in motorized kayaks in terms of stability, load capacity, seaworthiness, speed, versatility, mobility, comfort, and more.
This article answers the question “What are the advantages of motorized kayaks over non-motorized ones?”

1. Motorizing is easier than paddling

Not everyone can paddle their kayak over long distances, or in less than perfect conditions. Some kayakers suffer from disabilities, and others are elderly or not physically fit. Assisted paddling, namely paddling while an electric motor provides your kayak with additional propulsive power makes things easier, be it in strong wind, fast currents, or waves, as well as on flat water. When you motorize, you save your own energy, and you’re more comfortable.

2. Having a motor is safer than depending solely on paddling

A human powered kayak is an under powered vessel, by definition. In a sustained mode, an average adult paddler can produce between one tenth of a horsepower and one quarter of a horsepower, and this is very little, even in comparison to weak electric motors. In case you’re too tired to paddle back to your starting point, or due to unfavorable changes in water or weather conditions, being able to propel your kayak with a motor can be a critical factor that could save your trip, and even your life – A motorized kayak is safer than a non-motorized one.

3. A motor greatly increases your range of travel

Simply, having an extra source of power on board allows you to go further, since you can paddle to your destination, and motorize on the way back. So, whether you’re on a touring, fishing or on a photography trip, the motor allows you to cover more water, explore, and go to more places.

4. A motor allows you to take a bigger payload on board – cargo and/or passengers

You may want to take a passenger on board, or load your kayak with heavy camping gear, but this additional weight could make it too hard for you to paddle. In such case, a motor could make the difference.

5. Motors work well for trolling

You can paddle your kayak and fish at the same time, namely engage in trolling, but an electric trolling motor or a small outboard gas motor can do a better job than your paddle.

6. Driving a motorized kayak is fun!

Driving a motorized kayak can be fun too, especially if it’s a Wavewalk that’s outfitted with a powerful outboard motor. And driving standing, which is an option that all Wavewalk models offer, is even more fun – It’s comparable to skiing, except you’re going on water and not on snow, and it’s also comparable to water skiing, except for the fact that you’re free to go anywhere you want, including in choppy water and in waves, and you don’t depend on a powerboat to tow you.

7. A motor can get you to places that you otherwise couldn’t access

A Wavewalk outfitted with a mud motor (surface drive) can go where other boats can’t, and even where human powered kayaks can’t, such as mud flats, fast streams, etc.

8. Driving saves time

An S4 Wavewalk kayak outfitted with a powerful outboard motor can go at speeds approaching 20 mph, for as long as you want. This is more than five times the speed that a strong kayaker in a fast kayak (that is not a typical fishing kayak) can sustain for a limited amount of time, on flat water. In other words, a motor kayak can get you much faster to where you want to go, and back.

9. Motor boating is cool, and speed is exciting

Not everyone likes paddling, and not everyone thinks it’s cool. You may want to take someone on board your kayak, be it a child, your wife, an elderly parent, a fishing buddy, etc., and find that kayaking (or canoeing) doesn’t appeal to them, but going in a motorboat would, and to some of them the appeal would be greater if you go at high speed.

10. Helping other kayakers

Having a kayak powered by an outboard motor puts you in a unique position of being able to help other kayakers. You could do it by carrying heavy camping equipment on board your motorized kayak (realistically, only a Wavewalk…), taking passengers that aren’t fit for paddling, and by towing other kayaks.

Tandem kayak ocean rescue with the Wavewalk S4

By Captain Larry Jarboe

Wavewalk Adventures Key Largo

 

This afternoon, I took my workhorse S4, the White Knight, through the Key Largo Cut to get some video from Blackwater Sound and the Southern Everglades. Prior to reaching the IntraCoastal Waterway, I spotted a couple in a SOT kayak trying to paddle their yak into a stiff wind and close 2 ft. chop.

The planned video can be recorded another day. I volunteered to tow them back to the Marriott from where they had launched. They gratefully accepted.

We had a grand time beating our way home against the wind and the waves. Christina and Zach got a Wavewalk S4 real world demo and a motorized tour of Key Largo.

And, we all enjoyed another Wavewalk Adventure.

The S4 really is the boat that does it all!

Driving the S4 in rough water in a big boat’s wake (movie)

We wanted to show the Wavewalk S4 going in rough water, but since we couldn’t find water that was choppy enough in Key Largo, we made our own chop 😀
Larry drove his commercial fishing boat, the Line Dancer, Orit sat at the stern and shot video with our new Nikon camera equipped with a X83 optical zoom lens (great camera), and I drove an S4 in the boat’s wake.

The Line Dancer’s wake was V shaped, with pronounced “ridges” of waves and turbulence on both sides, and a quieter area in between.
When we went in open areas where the tidal current and wind created natural chop, adding the boat’s wake on top generated pretty hectic conditions that were a bit challenging to drive through, mainly because the motor on my S4 was a little 3.5 HP that didn’t allow for much planing and playing. This application calls for a more powerful motor, and a 6 HP outboard would have probably yielded more spectacular action shots. But at least we were able to demonstrate the principle…
When we drove in quieter zones, I just surfed the Line Dancer’s wake, and that was easy and fun.

 

 

What’s the real-world advantage of the S4’s ability to go through fast currents and chop?
“Real World” usually means you have to go from point A to point B, and you’re not just looking for some driving action fun. This can happen when you use the S4 as a tender for a bigger boat, or yacht, or when you drive in fast rivers that are swollen by water from melting snow in spring, or by tidal currents in coastal areas.
Jon boats and skiffs don’t excel in such conditions, to say the least, and inflatable dinghies are neither the most comfortable nor the most reliable choice. But the S4 shines in the chop, not just due to its natural, physical, “catamaran” stability, but also because it offers the driver to ride a saddle seat similar to the seat that other high performance vehicles feature, such as personal watercraft (PWC a.k.a. “jet ski”), all-terrain vehicles (ATV), snowmobiles, and dirt bikes.

 

 

Wavewalk S4 in blue water

Wavewalk S4 driven in choppy blue water in the Atlantic ocean close to Key Largo, Florida.
It was fun to drive this watercraft that seems to be almost immune to waves, wherever they come from.
Hopping on waves and making sharp turns was easy solo and with a passenger on board.

As a skiff, it’s extremely seaworthy, and as a kayak it’s anything but 😀

We towed it behind the mother ship, and it was a pleasure to watch how well it behaved… It can serve as a perfect boat tender for a big boat or a yacht – It’s seaworthy, comfortable, fun to drive and to paddle, can be beached anywhere, and it can carry up to three people on board.

The S4 in this movie is under powered by a 3.5 HP outboard motor – A 6 HP outboard would have worked better in this case, but still, driving this ultralight microskiff in the chop was a lot of fun. Thankfully, the S4 is not a solo skiff, and driving it with a charming passenger on board was even more fun.

We didn’t have to outfit it with a spray shield, as hardly any spray got it.
