Full size spray shield for motorized Wavewalk S4

The challenge: Keeping the front passenger dry when driving your S4 at full speed in choppy water.
The solution: Outfitting your S4 with a spray shield that’s big enough.

Wavewalk S4 outfitted with a full size spray shield and carrying a wheel cart on its deck. This wheel cart has an extension that can fit into the second slot in the S4’s front deck.

We used a 48″ x 24″ x 0.093″ Makrolon (Polycarbonate) sheet cut into three sections to create a 90″ long, 16″ high spray shield. This material is available at Home Depot.
We assembled the sections using Goop adhesive and rivets.
We attached the spray shield to the S4 deck using eyelets and short bungees.

This full size spray shield effectively protects from spray the passenger sitting in the front of the cockpit, and it further enhances the seaworthiness of your S4.

Warning: Stay away from Acrylic sheets because this material is too rigid for this kind of application, and it will develop cracks as soon as you start cutting it.

Big wake coming? No big deal – Wakes are fun!

This movie illustrates the concept of Wake-Immunity, which is part of the broader concept of Super-Stability.

A Wavewalk S4 motor kayak skiff is going in choppy water, in the ocean. This portable boat is so stable and its driver so much in control that a series of big lateral waves from the wake of a fast motorboat passing nearby at full speed does not present a problem or even a challenge to the S4 driver – It is just a new opportunity to have some wake fun in the sun…

 

Wave walking around the neighborhood

Just a short video shot while driving my S4 around the corner…

 

Couple observations –
This 6 HP outboard is no 10 HP, and this 8″ pitch prop is no 9″ pitch 😀
Driving this little boat in the chop is super easy and fun, whether it’s against the wind, in lateral waves, or in a following sea.

Wide wheels for Wavewalk S4 motor kayak skiff

I live close to the water, and I need to transport my motorized Wavewalk S4 over mildly rough terrain, and a sandy beach. The outboard motor I use is a 6 HP Tohatsu that weighs close to 60 lbs, so carrying it by hand is not easy.
Therefore, I had to make a trolley that features wheels that are bother high and wide. The trolley also needed to be transported on board the S4 without taking too much space.

I made a simple wheel cart from a pair of 13″ high and 6.5″ wide flat-free (non inflatable) wheels, and 3/4″ stainless steel tube mounted on a 1/2″ thick plywood board. This structure is attached to the S4 by means of straps.
The plywood board features a small wooden extension in its center. This extension fits in the first, widest slot in the S4’s front deck, and it allows to easily attach the wheel cart vertically, by means of a single shock cord (bungee).

Launching with this trolley is easy, and so is getting the wheels under the kayak after beaching.

 

The plywood is coated with two layers of urethane that protect it from the water.

 

Pulling is done either by holding one of the two molded-in front carry handles, or a strap attached to them.

 

Since these wheels are, big, another thing that this wheel cart offers is to run the outboard motor in a bin filled with freshwater, in order to rinse the salt out of it. This way, the motor can stay attached to the boat, and be clean of the salt.

This setup is enough to let the motor run in freshwater for a few minutes

I guess some readers may ask if this wheel cart offers the front passenger some protection from spray when the S4 moves in waves, and the answer is that it does offer a little protection compared to having nothing there.
