Tag Archive: floatation

Floatation (also spelled ‘flotation’) refers to means by which air is trapped and attached to a boat, or a kayak, in order to facilitate their recovery after an accident occurred. Various types of closed-cell foam can serve as floatation, as well as plastic bladders inflated with air.

Wavewalk® RHIB

Wavewalk no longer offers this configuration as shown here.
Since we now offer 12 ft long (7.25″ diameter) detachable inflatable flotation tubes as part of the W700 RIB , we offer only boats with one pair of regular size tubes (5 ft long / 6.5″ diameter) or one pair of the XL tubes (12 ft long / 7.25″ diameter).
We left this page and the RHIB configuration here in order to show yet another configuration that’s possible.

 

Wavewalk® RHIB – Rigid Hull Inflatable Boat

Before we go any further, the answer to your question is: -“Yes! This boat is great for fishing, for one or two anglers, once you detach the front pair of inflatable tubes, or both pairs, which takes less an a minute.”
In other words, the RHIB is simply a Wavewalk® 700 Z model that features an additional pair of inflatable tubes attached in the front.
And now that things are a bit clearer, let’s watch this video –

Why two pairs of inflatable tubes?

Good question! In this video, the front inflatable tubes touch the water on rare occasions, and when they do, they don’t seem to do much. This is because their purpose is to serve as secondary flotation, in addition to the saddle and the rear inflatable tubes.
In extreme cases, if the boat tilts very strongly on its side, these extra tubes could help prevent it from flipping. They can also help when the boat goes in bigger waves, since they add buoyancy to the bow, which allows the boat to go over the wave instead of through it. This can help prevent spray from getting into the boat, and make the ride less bumpy.
Extra flotation on both sides of the bow can be useful in other cases, such as when the boat is used for work or rescue, when divers climb on board from the water, and when heavy crab traps are hauled in.

What if I don’t want to use these extra inflatable tubes?

Each tube is attached to the boat with two carabiners, and it takes just seconds to detach it. It can be easily stored in the boat while still inflated, and both inflating and deflating it takes seconds, thanks to a user-friendly, wide (1.25″ diameter) inflation valve that saves you the need for a pump.

And what about that transparent spray shield?

The spray shield is attached to the boat with a bungee cord and two hooks. It takes a few seconds to attach or detach it, and once it’s not attached it’s just a flat, lightweight, flexible sheet of plastic that hardly takes any space, and can be easily stored inside one of the boat’s hulls.

What’s a RHIB?

RHIB is the acronym for Rigid Hull Inflatable Boat, also known as RIB (Rigid Inflatable Boat).
These motorboats are designed for extra stability and speed, and they come in various sizes. The smaller ones are motorized dinghies that can take a small number of passengers through rough water.
RHIB are very popular, and used in a wide range of applications, such as rescue, offshore work, tending bigger boats, diving, etc.
Anglers prefer not to fish out of inflatable boats because of the fishing hooks… but this is not an issue with Wavewalk’s RHIB, since its inflatable tubes can be removed instantly.

What’s special about the Wavewalk® RHIB?

Compared to rigid-inflatable dinghies of its size the Wavewalk® is –

  1. More stable: It features a catamaran hull, and a saddle that makes it easier for the driver and passenger/s to balance themselves.
  2. Easier to car-top: Its rigid hull weighs just 80 lbs, and it’s 12’10” (391 cm) long, which makes it easy to lean on the vehicle’s roof before sliding the boat upward.
  3. More versatile: Without the front pair of inflatable tubes it’s a Wavewalk® 700 Z model, which is a great fishing boat for one or two anglers. Without inflatable tubes it’s a nifty motorboat that paddles well, and without the motor it’s hands down the world’s best fishing and touring kayak.
  4. Faster: Videos of this RHIB and other W700 configurations show the unique Wavewalk ‘signature’ in the water – Practically no wake in the front, and a very slender wake at the stern. In this sense, this wake reminds a torpedo moving in the water, and not a boat, especially not a RHIB. Being typically wide and designed to plane, RHIBs leave a huge wake behind them, a sign of the great amount of power used to propel them.
  5. More comfortable: Some luxury small RHIBs feature forward facing seats or benches, and their driver can steer by means of a steering wheel or a joystick. But most small RHIBs offer just basic amenities, and their driver sits on their side, or on the side of the motor, next to the tiller, or on a bench in front of it. All these locations are sub-optimal in ergonomic terms and as far as driving is concerned, since they demand from the driver to face sideways, or drive with their arm stretched backward. Food for thought – Does any other vehicle require from its driver to sit in any of these awkward postures?… In contrast, Wavewalk’s RHIB offers its driver to ride a comfortable saddle and face forward, as they would in a personal watercraft (PWC) a.k.a.  jet-ski, an all terrain vehicle (ATV), or a snowmobile, which are vehicles designed for high performance in both tough conditions and at high speeds. Wavewalk’s RHIB is steered with a supersized joystick that’s intuitive to use and works perfectly when the driver sits or stands, without any adaptation required. This plug-in joystick and steering system require no installation, and it takes a few seconds to attach or detach it. The driver or the W-RHIB can start the motor in the most comfortable position, namely while facing backward, and once the motor is running, they can easily and swiftly turn around and face forward, as demonstrated in the video.

 

W570 with a 6 hp Tohatsu outboard motor

Why overpower this fishing kayak with a 6 hp outboard motor?

Earlier this year, Kenny One-Shot Tracy outfitted his W500 kayak with side flotation and a 6 hp Tohatsu outboard motor, and showed it going at 13 mph. This was intriguing, and several months later, after we came up with the W570 series for offshore fishing, we wanted to test it with a similar motor.
A W kayak weigh 60 lbs and it’s rated for 2-3 hp motors, so it goes without saying that using it with a 6 hp motor means overpowering it, since these motors are rated for moving boats up to 3,000 lbs, that is 50 times heavier.
However, testing and experimenting are part of any Research and Development (R&D) process, and we try as much as we can to test our products under various conditions in order to better understand possibilities, problems, and hazards, and inform our clients about them, so they have more options to choose from, and can make better decisions.

Tohatsu America showed interested in this project and cooperated with us through their dealer Steve’s Marine in Rhode Island, and we got the 6 hp Tohatsu motor (20″ shaft) in late October.

Motor weight and handling considerations

Although the 6 hp (20″ long shaft) Tohatsu is a sophisticated outboard motor, it is relatively lightweight for its class. However, at 59 lbs it still weighs twice more than the 2-2.3 hp Honda outboard that we’ve routinely used so far.  This additional weight was our first concern, and we wanted to experience what it means for a W kayak angler who uses such a motor.
We found the weight difference to be noticeable, but not a major issue – It’s possible to carry such a motor over short distances, whether on its own or mounted on the kayak. Dragging the kayak on a sandy beach was considerably more difficult, but not a big problem over a short distance.
Lifting the motor into the car wasn’t too hard either.

Transporting the boat in the car

Launching is easy both from the beach and from a dock, and the same is true for beaching.

The motor mount

Kenny reported that his 6 hp Tohatsu outboard had broken a DIY motor mount. Such accidents can be dangerous, so we knew that we had to consider both weight and power. Kenny later reported that his 6 hp motor worked with the TMM 20 motor mount that we had sent him, but we preferred to beef up a TMM 20-15 motor mount with an additional 3/4″ board for its vertical mounting plate, making it 1.5″ thick.

The boat itself

Another concern we had about the 6 hp motor’s weight was how our W570 would take it.
The following pictures show that we had no reason to be concerned, as the boat is pretty much level, and the side flotation modules rest several inches above waterline –

Driving the boat

Driving the boat with the 6 hp Tohatsu / 20″ shaft was easy and convenient.
This outboard motor features a 3 position gear system (Forward-Neutral-Reverse) that’s safer than a centrifugal clutch, and makes it easy to start any time. The fact that this motor is water cooled makes it relatively quiet in comparison with the air cooled 2-2.3 hp Honda.
Access to the motor’s controls is easy and convenient once you slide backward on the saddle all the way to the back of the cockpit.
The inflatable flotation modules stayed above waterline and did not cause splashing.

Load and additional passengers

Although a W kayak can carry heavier loads, we rate these kayaks for a total load of 360 lbs, for both safety and performance reasons. This number includes everything that the boat may carry, from passengers and their personal belongings to fishing gear, an anchor, and last but not least – a motor. With a 60 lbs motor and all the extra accessories that come with the Wavewalk 570, and considering the high speed in which you’re likely to drive, it would be safer to consider the W570 as a one-person motorized kayak, or a solo skiff, if you prefer. This is unless the user is not heavy, and they take a lightweight passenger on board. For example: A driver that weighs less than 200 lbs could take on board a small child weighing 60 lbs, plus some lightweight fishing tackle.

Fuel consumption

The 6 hp Tohatsu outboard model that we’ve tested features an integral fuel tank that allows it to go for 45 minutes full throttle, but as long as you drive a W570 with it you won’t go over 1/3 throttle since doing so is likely to increase your speed dangerously, unless you’re towing a bigger boat or several kayaks and canoes.

Accident

In one occasion, while the boat was going pretty fast, the propeller hit a rock on the bottom of the lake, and got ejected out of the water, as it’s designed to do in such cases. Lowering it back into the water presented no problem. The reinforced TMM 20-15 transom mount didn’t budge, and the inflatable side flotation proved that it’s useful in helping to prevent the boat from rolling (flipping) if it’s tilting strongly as it did following the impact and momentary loss of control that resulted from it.
The role that the inflatable flotation played in that accident emphasizes its importance.

Power and speed

A W kayak outfitted with a 2-2.3 hp outboard can go at 8.5 mph, full throttle, while the same kayak outfitted with a 6 hp Tohatsu motor can reach 13 mph at 1/3 throttle, a speed that for most people makes it too much of a challenge to drive safely. This is where we found that a 6 hp motor wasn’t the best fit for the Wavewalk 570. In other words, overpowering the W570 with such a powerful motor can be hazardous and cause accidents if you drive too fast relatively to your boating skills and/or to water conditions, or if you accidentally accelerate abruptly or even just too quickly for you to safely maintain control over the vessel.
This lightweight craft is no match for the power and torque of such a big engine, and that makes it too ‘nervous’ compared to when it’s outfitted with a smaller and less powerful motor that tks longer to accelerate.

Why you might want to overpower

Having said that, you might like this overpowered configuration if you’re a risk-loving speed fan who enjoys the feeling of danger. It’s your choice, as long as you’re aware of the safety hazards, and you know that the W570 isn’t rated for motors that are more powerful than 2-3 hp.

A more productive way to make use of such a disproportionally powerful motor could be for towing other boats. For example, if you use the W570 as tender (auxiliary service boat) for a bigger leisure craft such as a sailboat, it could tow the mother ship, if necessary, or tow another tender with several passengers and provisions on board (e.g. an inflatable dinghy).
If indeed you’re thinking about such use, make sure the towed craft are properly attached to your W570, and don’t use its handles or eyelets for this purpose.
Similarly, if you go on a camping and fishing trip in which several people take part, your W570 on steroids could tow several kayaks and canoes over long distances, and make life easier for the other members of your expedition.

If you’re thinking about driving up fast rivers, such as in springtime, or on fast tidal rivers, more power and torque may be justified, although it’s hard to imagine cases where a 2-3 hp motor would not suffice for your W kayak. Just remember that fast moving rivers are hazardous, and we recommend neither paddling nor motorizing in them.

Another case in which you could be interested to use a 6 hp outboard motor with your W570 is if you already own a larger boat that you propel with such a motor, and you want to alternate between your W570 and that bigger boat. For example, you may prefer to go fishing on your own in the W570, and take the bigger boat when you fish with your family and friends. If you don’t like to purchase a smaller outboard for your W570, you could try using your 6 hp outboard with it, and see how it works for you. If it does, it could save you the additional expense on a small motor. Just remember to be very cautious with the throttle when the motor is mounted on your W570.

Rating

All the above said does not imply that we rate the W570 for use with an outboard motor that’s more powerful than 2-3 hp, because we don’t. We think that using a W kayak with motors that are more powerful than 2-3 hp could be hazardous.
Again, the purpose of this article is to inform people about what using much stronger motors implies, and warn them about problems and dangers associated with such practice.

Fishing offshore – the next frontier

Fishing offshore – the challenge

Let us define Offshore Fishing as fishing in the ocean or in the Great Lakes, away from shore, beyond the breakers. Such fisheries are characterized by currents and wind that are hard to overcome without adequate propulsion, and therefore hazardous to fishers who venture in them in small, human powered vessels such as canoes and kayaks.

Typically, people who fish offshore from kayaks tend to do it in more protected areas such as bays, or stay within a short distance from shore.
While these fisheries are relatively safer in comparison to distant and deeper ocean fishing grounds, they still present considerable challenges to kayak anglers, as well as to those who fish from other small, light, non-motorized craft such as canoes and dinghies.

Offshore kayak anglers know that traveling out there in a human powered vessel doesn’t grant them that they’d be able to go where they want or even get back to shore. For this reason, some anglers venture on long distance fishing trips with a mother ship, I.E. a large size motorboat that carries their kayaks into the ocean, and enables the members of such expeditions to return safely to shore. Typically, the kayaks used for such trips are sit-on-top (SOT) kayaks.

Comfort and safety factors

Those who fish offshore from a kayak can be exposed to wind and waves from the moment they launch.  Sitting in the L posture isn’t easy to begin with, but having to deal with the waves’ rocking motion and the constant wetness and  makes it even harder, especially  for anglers who fish in colder regions, where low water and air temperatures can be a critical factor.

Some kayak anglers outfit their ride with an electric trolling motor, and while this certainly adds an element of safety and increases their range of travel, it still doesn’t offer them the freedom to go on long fishing trips, or overcome fast currents.
Outboard gas motors are more suitable for this purpose. However, there are no kayaks out there except Wavewalk’s that can be outfitted and used with this type of powerful and reliable propulsion in a way that makes sense to the user. The problem isn’t just the poor stability of the mono-hull kayak design and the lack of effective means for its users to stabilize it, but also the fact that outboard motors are rather heavy and they work best when they’re attached at the stern, which is too far behind the area in which the kayak’s user is seated – Anglers who try to outfit their sit-on-top, hybrid or sit-in kayaks with an outboard motor soon discover that they can’t easily reach its controls, and they can steer neither safely nor conveniently, even when they use a long and articulated (U-jointed) tiller extension.

Unlike kayaks, small fishing motorboats (e.g. Jon boat, dinghy, small microskiff) are designed for motorizing, and their users can drive them without experiencing the safety and ergonomics problems that occur in motorized kayaks.
The users of such small fishing boats sit either facing forward on benches stretching across their deck, or facing sideways on benches located along their sides, or on a raised seat or swivel seat.
The problem with those small craft is that they feature flat bottomed hulls that work well on flat water, but offer neither good stability in waves nor much comfort to their users in the constant rocking motion created by the waves.
The same is true for the three above mentioned seating solutions – Sitting on a bench is fine as long as you can stand up from time to time and stretch, but it’s uncomfortable when you’re constantly struggling to balance yourself, and you’re prevented from standing up in confidence.
As for raised seats, they are great for comfort as long as you can stand up whenever you wish to do so, and as long as you don’t have to balance yourself while sitting in them. However, this is not the case when your boat is being rocked by waves, and in such cases you’d be likely to experience discomfort.

Most small fishing motorboats are not designed for car topping, or are just too hard for one person to car top. Therefore, they require transportation by trailer, which means launching and beaching in boat ramps, with the time loss and aggravation that entail…

For all these reasons, small flat-bottomed motorboats offer limited offshore fishability.

As for ergonomics, the W570 offers its users to travel facing forward while riding a saddle similar in size and shape to the saddles commonly found in personal watercraft (PWC – jet-ski). The riding position is unmatched as far as the power, control, comfort and balancing capabilities it provides, which is why it is so well suited for small, high performance, personal, offshore motorboats. No wonder that other high performance personal motor vehicles such as all terrain vehicles (ATV), dirt bikes, and snowmobiles all feature similar saddles.

The new W570 series

A few weeks have passed since Wavewalk announced its new W570 series of kayaks that are ready for motorized offshore fishing. During this period we’ve obtained substantial input about this new concept from W clients, fans and dealers who fish in different parts of the world.
It’s possible to classify their reactions to the W570 series into three categories – negative, mixed and positive.
Those who reacted negatively argued that there’s no real need for a spray shield and large-size inflatable flotation tubes, and consequently, these new accessories might reflect poorly on the W product and brand.
Those who had mixed reactions said that although personally they don’t see the point in either using or offering these new accessories, there may be a demand for a such a car-top boat among fishers who are looking to fish out of a small motorboat in the ocean or in large size bodies of water such as the Great Lakes, big and fast rivers, and other challenging fisheries.
Those who reacted entirely favorably to the new W570 series are mainly people who already fish offshore or in bays and large estuaries, and are familiar with the challenges that anglers face in such fisheries. Incidentally, there’s a higher percentage of motorized W kayak anglers in this third group compared to the general population of W angers.

All three points of view are legitimate and interesting –
Those who argue against the new accessories stress that as far as motorizing goes, Wavewalk has already shown in a most convincing way that its W500 series was perfectly suitable for driving while outfitted with an outboard motor at speeds that are similar to and even higher than the typical speed for other small motorized fishing craft such as Jon Boats, motorized square-stern canoes, dinghies and various flat-bottom watercraft classified as small-size microskiff. Therefore, adding large size inflatable tubes and a spray shield to a W kayak is overkill.
This argument is correct, obviously, but only so in the context of traditional fisheries where these other small motorboats are commonly used, which are inland, flats, small and medium size lakes, slow moving rivers, and generally speaking, in areas that are not particularly challenging in the sense that anglers who fish in them are unlikely to overcome either powerful and fast currents or waves while launching, driving and beaching their fishing boat.
It goes without saying that these relatively protected fisheries correspond to areas where the majority of fishing kayaks and canoes are used, as well as most other small, flat-bottomed boats. This fact puts the new W570 series at the edge of the current market, for better and for worse, in the sense that while the current market for it doesn’t seem to be big today,  there could be a substantial yet unfulfilled demand for such innovative, high-performance personal boat, whose offshore performance surpasses that of mono-hull fishing kayaks as well as traditional small motorboats when comfort, stability, ease of transportation, and launching & beaching are taken into consideration.

Keeping the cockpit dry

W kayaks offer several effective means to keep their cockpit dry on offshore fishing trips –

Typically, launching and beaching are the events that produce more spray, and are likely to get some water in if you don’t take any precautionary measure to keep the cockpit dry, which is easy since all W570 models come outfitted with a spray shield that blocks water from getting in from the front.
In addition, you can launch while riding the saddle aft of the middle part of the cockpit. Doing so would raise the kayak’s bow and further decrease the likelihood of spray getting into the cockpit.
And last but not least, all models from the W570 series feature a preparation for cockpit cover, which allows you to attach a small-size tarp over the front and middle parts of the cockpit, and thus prevent any spray from getting in. Once you’ve passed the surf zone and you’re out in blue water, you can easily detach the cockpit cover within seconds, and store it in one of the hull tips behind you.

These three defensive measures work effectively, and in addition, if any spray got in, dealing with it is very easy – All you need to do is take a couple large-size towels on board and drop them on the bottom of the hulls behind you, near the hull tips.
If any spray gets in, it will be drained to the bottom of the hulls, and the water would normally flow backwards, since the kayak’s stern is usually a bit lower than the bow.
The towels would soak the water, and if you see that a towel has reached its soaking capacity, all you need to do is grab it and squeeze the water outside the cockpit, which takes just a few seconds. This method is commonly used by canoeists and sit-it kayakers who travel in moving water.
If you’re into gadgets, who can replace the towels by an inexpensive hand-activated bilge pump. These pumps are popular among sit-in kayakers, canoeists and other small boat users. Their disadvantage over towels is that they become effective only in case a considerable amount of water has accumulated at the bottom of a hull, which isn’t likely to happen.
Another simple and effective accessory that kayak, canoe and small boat anglers use for bailing water out of their craft is a small-size bilge bucket. While this accessory is highly effective for this purpose, it’s not as easy to use as towels and bilge pumps are.

The Wavewalk 500 – Motorized for offshore fishing

Overview

The W500 is a new type of small watercraft that can be outfitted for high performance as a Rigid-Hull Inflatable Boat (RHIB) technology.
RHIBs are known for their stability, high performance and seaworthiness in demanding applications such as lifeboats, rescue, and military operations. They also serve as tenders for large boats and ships, and as work boats in offshore facilities.
Unlike in regular RHIBs, the inflatable tubes that come with the W500 are easily detachable, for storage during transport, or in case they’re not needed, such as when you paddle or motorize on flat water.
And unlike RHIBs, the W500 can be outfitted with flotation tubes only in its rear part, so they don’t interfere much with fishing or paddling.
In addition, the weight of the outboard motor at the stern offers the W500 user to sit or stand closer to the bow while keeping the boat level. This slightly forward position further increases the range of motion when they fish, or paddle while launching or beaching in water that’s too shallow for motorizing, or in water with abundant aquatic vegetation.

The W500 can serve as a small, lightweight, car-top, durable microskiff with enhanced offshore capabilities.

The W500 user can drive it in the powerful and stable Riding posture, similarly to a personal watercraft (PWC, jet-ski), as well as standing up. Both types of boat feature a similar longitudinal, high saddle, although the W500’s saddle is longer, and allows the user to drive or paddle from different locations fore and aft of the middle of the cockpit.

Since motorizing at high speed in choppy water involves bumping into waves and generating spray, the W500 is offered with a lightweight, detachable spray shield that can be removed within seconds and stored flat and upright in one of the hulls, behind the user.  The reason we made this accessory detachable is in order to enable the user to get it out of their way when they fish, store it on board, and re-attach it only when it’s needed.

This video demonstrates the W500 offshore, in choppy water:

Capabilities

  • Launching: Almost anywhere, including sandy and rocky beaches, steep banks that require seal-launching, remote beaches that require portaging and won’t allow for wheel carts, shallow water where only poling and paddling works, water with seaweed and/or grass, etc.
  • Beaching: Same as above, except less steep banks.
  • Mobility: Being a triple propulsion craft (motorizing, paddling, poling) the W500 can get anywhere a W kayak can, which means in seaweed, grass, reeds, over obstacles, in shallow water, in fast tidal currents, in strong wide, offshore in the chop,  etc.
  • Speed: 8.5 mph with a 210 lbs passenger on board and running a small, 2 HP Honda air-cooled outboard motor.
  • Range: Typically, when using a 2 HP outboard motor, 1 quart of gasoline (0.9 liter) would suffice for 1 hour at full throttle.
  • Maximum recommended load for passengers and their gear: 320 lbs (145 kg) when motorized.

 

Features

The Wavewalk™ 500 comes ready for offshore motorizing.
It comes with these standard features:

  1. A transom motor mount ( TMM 20-15). The mount requires installation that takes up to 5 minutes of easy work. The new TMM 20-15 transom mount fits both 20″ (long) and 15″ (short) propeller shafts. We recommend using a 20″ (long) shaft motor with all our kayaks and boats.
  2.  A pair of high-capacity, detachable, inflatable side flotation modules (INF). Color:  Black. Attaching and detaching these modules takes seconds. Inflating them is easy and does not require a pump.
  3. A transparent, easily detachable and easily stored spray shield.
  4. A set of 4 additional tie-downs (eyelets) on each side of the boat (total of 8 extra eyelets) enabling  attaching the side flotation modules to it, as well as attaching an extra pair of flotation modules for extreme conditions.
  5. A preparation for cockpit cover that also enables attaching the spray shield to the front of the cockpit.
  6. A pair of clamp mounted Tite-Lok fishing rod holders.
  7. A saddle bracket – standard. Starting from 2014 all W models feature a saddle bracket – standard.

 

Technical Specifications

  • Total length: 11’4″ (136″) 345 cm
  • Width: 29″ (73 cm) without the inflatable flotation modules
  • Weight: 60 lbs (27 kg) without accessories
