2. ABOUT THE S4
The S4 is a catamaran (twin hull), super-stable, high performance, extremely versatile and seaworthy cartop microskiff that’s easy and fun to drive at high speed, both on flat water and in rough water.
The S4 also works perfectly for kayak fishing, namely with its user or crew paddling it.
The S4 is Wavewalk’s 4th boat series since 2004, following the 300 (Mark I and II), 500, and 700 series.
Like all other Wavewalk products, this boat is 100% Made in USA.
The S4 delivers the highest performance in the field of small boats and ultralight micro skiffs, even before you’ve reached the water, starting from the fact that at 100 lbs it doesn’t require a trailer for transportation, and it’s easily portable even on rough terrain.
Its patented twin-hull (catamaran) design delivers more stability than any boat of comparable size out there, including wider and heavier ones. This allows for driving in fast currents, in choppy water, and in the ocean.
The S4’s extra large cockpit (8′ long x 38″ wide) offers ample room for two anglers or hunters and their gear, or for up to three adult passengers – a total of up to 600 lbs.
The S4 features a long saddle seat similar to the saddle of other high performance vehicles (e.g. Jet-ski, ATV), which offers maximal balancing capability and full comfort in choppy water, and long trips.
The S4 features a skiff’s stand up casting platform at its bow.
The slanted sides of the S4 cockpit enable its passengers to paddle with more ease and better control than canoes and tandem fishing kayaks offer.
The S4 has an extremely shallow draft, and this fact in combination with its portability, load capacity and high performance as a paddle craft makes it the most practical solution for shallow water fishing.

The bracket in the front provides additional support for the stand up casting platform, and the rear bracket serves as extra support for a motor mount.
Each bracket is attached to the vertical wall that’s adjacent to it by means of two rivets. The rivets are sealed with waterproof adhesive.

4. BENEFITS
Best Stability in Small Boats
- Initial (Primary) Stability: The S4 is more stable than any kayak, canoe, Jon boat and micro skiff of similar size. A 200 lbs person standing with both feet in one of the S4 hulls will make it draft barely 1″ lower than it would if that person stood with one foot in each hull – hardly a noticeable difference.
- Secondary Stability and Balancing Capability: The unique combination of a saddle seat (such as ATVs, PWC and snowmobiles feature) with high-volume twin hulls enables the passengers to balance themselves easily, intuitively, and more effectively than in any other boat, including kayaks, canoes, Jon boats, dinghies, skiffs, and personal watercraft (PWC / ‘jet-ski’).
The S4 is unrivaled in Stability terms.
Best Boat Ergonomics
The 15″ high saddle featuring in the S4 is similar to the saddle featuring in other high performance land and water vehicles, such as All-Terrain Vehicles (ATV), Personal Watercraft (PWC / ‘jet-ski’), and Snowmobiles, as well as certain Rigid-Inflatable Boats (RIB) designed for high speed motorizing offshore.
Passengers riding this saddle can travel for long hours, including in choppy water, without suffering from back pain or fatigue. This is due to the fact that while seated in the Riding position, with a leg on each side of the saddle, the passenger’s legs support them in the most effective way, and no horizontal pressure from a backrest is being applied on their lower back.
In addition, the S4 passengers can stand up any time they want, and keep driving and paddling while standing up. They can even lay down with their back on the saddle, and relax. Switching between positions assures that no extreme fatigue or tension would build up in any part of the passenger’s body.
Easy Transportation and Full Portability
The S4 weighs 100 lbs without a motor attached to it, and one person can cartop it. Therefore, it does not require a trailer for transportation.
Total Mobility and Increased Range of Travel
The S4 can be dragged or carried over rough terrain, and launched practically anywhere, whether it’s a rocky beach, shallow water, or other difficult spots that are not accessible to other boats.
The S4 can go almost anywhere, thanks to a number of special features –
No other boat offers such a combination of shallow draft and total multi-modal propulsion, namely the ability to keep going in an effective paddling and poling mode even if the water is too shallow and/or infested with weeds to allow for motorizing.
No other boat, big or small, works so well both on flat water and in the ocean chop. The S4 is both the most stable and seaworthy boat for its size.
Large Size Onboard Storage
The Wavewalk S4’s twin hulls offer 260 gallons (34.7 cubic feet) of onboard storage. This huge volume is comparable to the storage space offered by a 16 ft Jon-boat, or a regular size skiff.
Speed
So far, the speed record for the S4 is 17 mph. This record was set with a 9.8 HP Tohatsu outboard motor by Captain Larry Jarboe, and documented in video. Based on the boat’s perfect performance at this speed, it could go faster with a more powerful motor. Please note that Wavewalk does not recommend using motors that are over 6 HP with the S4.
Shallow Draft
- Empty, no motor: less than 1″ draft
- Loaded with 200 lbs: less than 3″ draft
- Loaded with 400 lbs: less than 5″ draft
5. ACCESSORIES

Mounting Plate Tech Specs
