Don’t overpower your fishing kayak, but if you do…

Aside from legal considerations, there are good reasons why you shouldn’t overpower your fishing kayak, and they all boil down to one word: Safety. Simply, overpowering any boat, including a kayak, is hazardous, weather because the extra torque and speed make the boat harder to control to a point where the driver could lose control and capsize it, or because a powerful motor can overstress the part of the hull to which it’s attached (typically the stern), and make it develop cracks that could cause the boat to sink.

When common fishing kayaks are concerned, most online videos that show such a vessel driven while outfitted with a gas outboard motor reveal an overpowered setup – Those SOT kayaks are hard to drive mainly due to poor stability, unsuitable ergonomics and insufficient access to the motor’s controls. In some cases the kayak’s stern is dangerously low to a point  where it’s partially submerged.
As for Wavewalk kayaks, they work perfectly with small outboard motors, but in some cases their owners outfit them with an outboard gas engine that’s too powerful (I.E. exceeds 3 hp), mainly because these boats work better with outboards that feature a long propeller shaft (20″), and such motors are hard to find in the range of small-size motors.

This video demonstrates an ‘overpowered by far’ configuration – A 6 horsepower Tohatsu outboard that fits boats up to 3,000 lbs mounted on a 60 lbs Wavewalk:

Needless to say that such outfit is hard to drive, and requires extreme caution. Inexperienced drivers should not drive overpowered boats, especially such small ones.

While it is strongly recommended not to overpower your Wavewalk kayak, if you’re determined to do so, here are some tips you may want to remember –
First, make sure the boat is properly outfitted with enough flotation. This may turn out to be critical in case of an accident. Remember that the more powerful the motor the heavier it is, and that in case of an accident, the amount of flotation you use should suffice to keep the boat afloat with the motor attached to it.
Second, make sure the motor mount you use is sturdy enough – Remember that the motor mounts offered by Wavewalk are rated for 2.5 hp to 3 hp, and they won’t withstand the torque generated by more powerful motors. Note that the TMM 20-15 mount featuring in the above video was reinforced with a double mounting plate. Reinforcing the knobs under the deck with wide plates is recommended as well.
While a spray shield isn’t required for driving your motorized Wavewalk on flat water at regular speed, it’s pretty useful when you drive in choppy water and at higher speeds. The same is true for a cockpit cover.

Motorized kayak or microskiff?

The current trend in fishing kayak design is to produce kayaks that are increasingly wide and heavy, and no longer qualify as car-top boats but rather as microskiffs or small boats that require a trailer. This defies the purpose of kayak fishing, but some anglers opt to purchase and use these boats.
The question is, how practical is it to motorize these excessively big kayaks?
It turns out that most large-size fishing kayaks can be outfitted with electric trolling motors that are mounted either on the side or in the middle of the kayak – right in front of the user. It’s not the most practical setup, but some anglers need this extra propulsion power to get where they want to fish, or get back from there, since paddling long distances isn’t for everyone. Some are outfitted with an electric motor mounted in the back, at a big distance from the driver, which isn’t very practical when you go in shallow water where weed and grass are commonly found, and these tend to get entangled in the propeller.
As for outboard gas motors, we haven’t found a single fishing kayak that offers an acceptable solution for an outboard gas motor, as such motors must be stern mounted due to their weight, and mounting a motor that far behind the driver doesn’t work well, for various reasons related to steering, convenience and safety.
The only fishing kayak that can be flawlessly motorized is the Wavewalk, as we’ve already mentioned here.

Wavewalk has recently introduced a set of accessories that enhance the performance of its patented catamaran kayaks in terms of motorizing, and turn them into high performance car-top motorboats, or in other words – personal microskiffs. The difference is not just in the improved performance, but in the looks as well –
With its new, black, inflatable side flotation modules, the new W570 INF 20-15 looks like a rigid-inflatable boat (RIB), which is a type of boat commonly associated with high speed and rescue operations.
The new transparent spray shield makes this little boat look like a marine motorbike, or a twin-hull personal watercraft.

This movie shows this new model in action in the ocean, in choppy water:

Being able to drive this microskiff while standing is not just a useful feature – it’s a lot of fun.  Being able to launch it almost anywhere, without needing to use a boat ramp is a huge plus, and its light weight makes it easy to car top – There’s absolutely no need for a trailer for this craft.

Interestingly, the spray shield is detachable, and it can be removed within seconds if you find that it’s in your way when you fish – After all, this boat offers its user to fish from the front, and not from its sides.

In sum, we see a noticeable upgrade in what Wavewalk offers in the market for portable fishing motorboats.

New speed record for a motorized W fishing kayak

Kenny “One-Shot” Tracy, a W kayak angler from Maryland, broke the speed record for a motorized kayak of the W500 series. He outfitted his W fishing kayak with a 6hp outboard gas motor from Tohatsu.
This powerful engine weighing 57 lbs empty propelled Kenny’s kayak at 13 mph in Chesapeake bay, at 1/3 throttle:

The kayak was stable and its driver stayed dry, and Kenny reported neither tracking nor steering problems.
Before starting his speed tests, Kenny outfitted his W kayak with side flotation.
The motor is mounted on a TMM 20 Wavewalk transom motor mount.

This successful test further reinforces the notion that when motorized, the patented catamaran kayak from Wavewalk can serve as a personal motorboat, or car top microskiff.

When a fishing kayak turns into something else…

Sometimes a design offers more than the eye meets. In this case, a patented fishing kayak offering unrivaled stability and comfort as well as unmatched storage space and dryness can turn into a self-motorized water skiing device by virtue of its small size, light weight, ease of use, and tracking capabilities.

Watch this video:

Just drive around, standing up, with no motorboat to tow you… And you don’t need to be an athletic youth to perform this trick and enjoy it.

The middle aged guy demonstrating the kayak in this video is 6 ft tall and weighs 200 lbs.

The basic model of this rotationally molded Polyethylene W kayak weighs 59 lbs. The 2 hp Honda outboard motor weighs 29 lbs, and the transom motor mount adds five more pounds to the total.
The driver controls the motor and steers the craft through the tiller handle, which is outfitted with an articulated (jointed) tiller extension allowing for effective steering even when the driver is standing up.
This little wonder fits on top of any car rack, and inside some medium and large size vehicles.
It’s easy to carry just by dragging in on the ground by a strap attached to its bow, as demonstrated towards the end of the video clip.

Is this an effective solution for offshore trips? It is, and a simple and effective cockpit cover would provide additional protection from spray.

This watercraft can be outfitted with detachable flotation modules that would keep it afloat in case of a capsize accident leading to much water getting inside.

The more traditional ways to look at this small boat are either as a motorized fishing kayak or a personal microskiff. The difference between the two viewpoints is related to whether you’re used to fish out of a kayak or from a motorboat.

Berny Marsden’s Stitch and Glue W Kayak, UK

This is the latest DIY W kayak project –

It’s the first DIY design allowing to take the boat apart.

Says Berny:

-“I have been busy building my W kayak.  I tested it today and did a dive off it with great success.  I decided to use the aluminum connecting poles and make the craft in three parts. This has the benefits of easier construction, easier transport and easier storage.
As I anticipated, it is very stable and should make an ideal sea diving platform. The seat section provides inherent buoyancy if it should capsize. However, I tried very hard to capsize it today and it never looked like getting close to it.
I am so pleased with it and very glad I saw John Forney’s Design.
I would be grateful if you could thank him for his help and advice.
Also, thanks for your help and encouragement.”
