Great little boat, we have a lot of fun with it

We live on the sound side, which is where we usually use our S4 skiff. Oceanside is pretty rough here at the bottom of the outer banks.

We have hopped islands a bit crossing channels and such, but mostly we roll it down to street to the neighborhood pier and slide it into the sound.

Haven’t really put much gear on it, we use 6hp Tohatsu. We mostly fish from our neighborhood pier, and use the skiff to beach on the sandbars on the sides of the intercoastal waterway to dig up sand dollars.

Great little boat, we have a lot of fun with it.

I have a lot of folks ask about the S4 here, it certainly catches peoples attention

Decimating blue catfish with my S4

By Captain Larry Jarboe

Wavewalk Adventures, Key Largo

Another short visit to the Mallows Bay National Park on the Potomac River.
Launched the S4 at 10:30 AM and was back on the trailer and headed home before 1 PM.
So, this is what an hour’s worth of fishing looks like when you follow the tide.

And, have a vessel to get you far enough out to the river channel where the Blue Cats are getting fat for the winter.

These fish are delicious and considered an invasive species by the Md. Dept. of Natural Resources. They want fishermen to catch and kill them all.
Been doing my part…

(Continued): The next day…

What other kayak or micro-skiff can carry countless catfish for live delivery? The catfish carrying capacity of this boat is unbelievable.

Had another nice day at Mallows Bay but I think I will target some other species.

Starting to smell like catfish bait…



3.5 HP or 6 HP outboard motor for my S4 microskiff?

The Wavewalk S4 is the lightest portable microskiff that you can use without having to compromise on stability, performance, seaworthiness, or carrying capacity.
The S4 can be powered by a 6 HP outboard gas motor that’s powerful enough to work as an auxiliary motor (“kicker”) for 3,000 lbs sailboats, you can drive it in the ocean without ever getting seasick, it can comfortably carry three adult passengers on board in choppy water, and you can pull it through rough terrain when it’s attached to a lightweight wheel cart.
The question is, can you improve its portability? –

Weight vs Power and Speed

Pulling a wheel cart loaded with a 100 lbs microskiff outfitted with a 60 lbs 6 HP motor is easy when you go over pavement, even terrain, mowed grass, and other generally flat, regular, and compacted terrain. It’s more difficult when you have to pull it up a sandy beach, or a winding trail in the woods that’s riddled with rocks and tree roots.
There are two ways to improve the S4’s portability, which are to outfit its wheel cart with bigger and wider wheels, and to reduce your load by using  a lighter motor, that is a less powerful one.

A 20″ Long (L) 6 HP outboard weighs a little over 60 lbs, and a 3.5 HP Long (L) motor weighs almost 20 lbs less, that is a little over 40 lbs. Reducing the total weight that you need to pull (I.E. boat + motor) from 160 lbs to 140 lbs can be meaningful, and may be worth considering.
Driving the S4 with a 6 HP motor is fun, and fun is very important when you’re talking boating. Going fast can be important too, since you may want to get as quickly as you can to where the fish are, or at least where you hope you’d find them.
A 3.5 HP makes the S4 go slower than a 6 HP does. However, using 3.5 HP motor does not reduce the boat’s seaworthiness or its carrying capacity, and speed is the only thing you’d sacrifice by using one, compared to using a 6 HP motor. Ironically, going more slowly in big waves could result is getting splashed by more spray, since a 6 HP is powerful enough to get the S4 to cross the waves on a plane, from crest to crest, while going more slowly with a 3.5 HP motor will force the S4 to go up and down the waves, negotiating each wave individually, and getting sprayed occasionally.

The best ratio of weight to power in portable outboard motors

One figure that’s worth remembering when choosing a small, namely a portable outboard motor, regardless of its power: The best ratio of weight to power is about 1 lb to 10 HP. This 1/10 ratio, or close to it, can be found in several models from different brands, and the closer the motor is to this ratio, the better it would serve you in terms of power and portability.

Does the S4 work with short shaft (S) outboard motors?

No, it doesn’t. The S4 works only with 20″ Long (L) shaft motors.

Can I use a motor that’s smaller and lighter than a 3.5 HP motor with my S4 microskiff?

Yes, it’s possible, but doing so means that the S4 would be under powered, and its overall performance could be reduced to a level where you might not enjoy using it… (speed matters!)
Also, some 2.5 HP motors weigh as much as a 3.5 HP motor, which in some cases is basically a 2.5 HP motor that the manufacturer equipped with a high capacity carburetor.

Generally speaking, the smaller the motor the worse its weight to power ratio is, unless you use an air cooled motor instead of a water cooled one, but such extra small air cooled motors are much noisier than water cooled motors.

Carrying the motor by hand

You may need to carry the motor by hand, and while doing this with a 60 lbs motor may be possible for a young and strong man, there comes a time in life when one must be somehow less ambitious, and avoid overdoing things. This is to say that for many boaters, a 60 lbs motor is not portable in the full sense, and reducing this weight by almost a third, down to almost 40 lbs, can make a big difference.
