Wavewalk 700 Test Ride 2017

By Rox Davis

 

Got my W700 and got to making some adjustments.
Kept the motor mount it came with for now, but will be making a new one soon.
It was a fun day at Rainbow Res in Ct. Motor ran like a top, I even caught some Bass.
Love how the W700 handled and felt going thru the choppy water.
And just like the W500 which is a very stable kayak, the W700 is more of a solid ride.
All in all I love it and can’t wait to finish some changes and two of us get out there fishing.

Thanks Wavewalk for another fine water craft

Life is good.

How much HP for my S4 skiff’s outboard motor?

This article summarizes research performed by Captain Larry Jarboe, as well as inputs from Wavewalk dealers and S4 clients. Its purpose is to answer a frequently asked question (FAQ) from prospecting clients, which is “What outboard motor should I choose for my S4?”

The answer is that the outboard motor you should choose for your S4 depends on two factors, which are

  1. How much power you need
  2. How important is the motor’s weight for you

And there is a trade-off between power and weight, namely that the more powerful the motor, the heavier it is, and the harder it could be to carry it.
In any case, the motor should be a 20″ log shaft (L) model, and not a 15″ short shaft (S) model.

2 HP outboards

Outboard motors in this class weigh around 30 lbs, which makes them fully portable even for a user who’s not very strong. A 2 HP motor can propel an S4 skiff with one person on board at speeds up 8 mph, even in choppy water. This speed would decrease as the boat is required to carry more passengers on board. S4 owners who tested such motors with their S4 skiff reported that the boat felt under powered, which means that they felt like going faster, but the motor lacked the powered required for this. For this reason 2 HP motors are not popular with S4 users. Another reason for their lack of popularity is the fact that being air cooled makes them noisier than water cooled motors.

3.5 HP outboards

Outboard motors in this class weigh around 40 lbs, which makes them still portable, but less so than 2 HP motors. A 3.5 HP motor can propel an S4 skiff with one person on board at speeds up 14 mph, even in choppy water, and it can propel the boat at 12 mph with three passengers on board in  moving water. This size motor is the most popular among S4 and W700 users, as it offers a good trade-off between power and weight for people who must lift the motor or carry it by hand over long distances.These motors are also less expensive than bigger ones.

6 HP outboards

Outboard motors in this class weigh around 60 lbs, which makes them portable only for very short distances, and not for everyone. A 6 HP motor can propel an S4 skiff with one person on board at speeds up 18 mph, and it can propel the boat at 14 mph with three passengers on board. 6 HP motors are the second most popular motors among S4 users.

8 HP outboards

Outboard motors in this class weigh around 80 lbs. At such weight, these motors can no longer be considered as portable, and the only reason to use them is the fact that they are offered with electric ignition, which eliminates the need to start them by pulling a cord. The S4 outfitted with an 8 HP motor performs well in choppy water, but it could feel over powered for an inexperienced driver, which should avoid using such motors with their S4. Heavy users may benefit from driving with a U-jointed tiller extension, in order to move some weight forward from the stern to the middle of the boat.

6.5 HP mud motors

Mud motors are bulkier and heavier than regular outboard motors. A 6.5 HP mud motor weighs around 80 lbs, and it’s not portable. The reasons you’d want to use such a motor instead of a regular outboard of similar power are if you need to go in very shallow water (skinny water) and mud, and if you fish or hunt in water with plenty of vegetation and underwater obstacles. The S4 performs very well with a such a mud motor. We do not recommend using less powerful mud motors because typically, these motors require more power than regular outboard motors do.

Electric outboard motors

Some electric trolling motors are described by their manufacturer as “outboard motors”, namely comparable in power to small outboard gas engines. If you consider such electric motors, we recommend remembering the laws of physics, and applying the formulae for Kilowatts to Horsepower conversion, which are:

  • 1 KW = 1.34 HP
  • 1 HP = 0.745 KW

 

 

 

 

 

 

Wavewalk S4 with a 6.5 HP mud motor – first test

By Chris Henderson

Fishing Kayaks of Gig Harbor

Today I was able to do my first test drive of the Wavewalk S4 with a mud motor!

As a duck hunter the potential for the S4 is incredible. Couple that with a mud motor and you can access places that others cannot go. I hunt tidal mud flats where traditional boat motors are difficult to use due to the changing tides (water depth) as well as the sand bars that constantly shift. The mud motor allows operation in very shallow water and lets me get over those sand bars. Other duck hunters hunt in flooded timber where the logs eat propellers for lunch and occasionally eat whole lower units. The mud motor is the only way to travel safely in those kind of swamps. That is why putting a mud motor on the S4 is like combining peanut butter and chocolate.
This was my very first run, so I have a lot to learn about operating this kind of motor.

There are a lot of different styles of mud motors out there and the cost can be very prohibitive. But I found a kit which is created by Mud-skipper called the Twister. Rather than a straight shaft it has a curved shaft. At first I was concerned that due to this the turning radius of the boat would be dramatically effected. As it turns out that fear was unwarranted. The two hulls actually keep you from turning too sharp which could cause you to overturn considering the nature of how the motor turns. The 6.5 hp was plenty of horse power and I cavitated way before I ran out of power.

Lots of experimenting to do to get it all dialed in but it was a great first test run.

Wavewalk S4 with 2 HP Honda outboard in strong wind, lake Simcoe, Ontario, Canada

By Pyt Rotary

Ontario, Canada

Lake Simcoe is a 280 square mile lake in Ontario.

12km/h [7 mph] with Honda 2Hp against wind of 24km/h [15 mph]

Lots of fun except my rocky mistake to not have enough gas with me.
I got excited and let the boat run for 15km straight into the lake and realize I am out of gas.
I paddled back half the distance and got gas from shore.
Now I know… From now on I will carry enough gas with me.
Luckily I paid with just one blister on my hand.

I did come back at night and feel SUPER SAFE in it.
It is a great, fantastic boat.

 

(added comment) –

The S4 is SUPER, SUPER, SUPER stable. It does not sway at all.
I have been in bigger boats with V shape hulls.
Those boats don’t have the same stability on the water as the S4. The waves hammer them straight in the teeth.
The catamaran design cut the waves like a knife cuts through butter.
Definitely there is room for more HP on the S4.

It was my fist ever trip with a gas motor, I do use W500 with an electric motor but never played with gas before. Lots of fun. Now I can reach easily lots of my fishing spots.
Regards from Ontario, Canada.

Wavewalk S4 first sea trial on windy day, with 5 HP outboard motor, Key Largo. Video and review

By Captain Larry Jarboe

Florida Fishing Kayaks

Some thoughts about the Wavewalk S4

 

Beautiful lines!  It may be the Cadillac of kayaks but it looks like a seagoing Corvette.  Is it a high performance motor yak or a portable runabout?
Super stable.  Because it looks so seaworthy, most other powerboats do not slow up when passing port to port.  No problem.  The S4 slides through wakes easily without leaving planing mode.
It seems to run a little faster than the W700 with the same motor.  I believe the wider hulls act like a pair of skis to help the boat skim across the water.  Handling tiller, camera, and a GPS at one time is beyond my skill set.
Tracking through turns while planing is wonderful.  The boat’s stern does not slide like many skiffs do.
The S4 is so easy to spin your body to face the outboard motor because the hulls are so wide.  You can keep your feet inside the vessel.
Also, the S4 is the perfect vessel for folks who are tired of maintaining their leaky inflatable tenders.  Or, people who want a lifeboat that can be used for shade or transport, too.
I still think the W700 is the boat that does it all, but the S4 is the boat that does it all, and more!

The video shows 15-20 knot wind close chop.  No problem.  Try paddling against this.

P.S. – This boat could make a run from South Florida to Bimini.  But, for the time being, I will be staying in waters managed by our Country.
