kayak design

Kayak Design is the process of designing a kayak for a specific application (e.g. Touring kayaks, Fishing kayaks, etc.), and other parameters such as the user’s size, proficiency in paddling, the overall load capacity required from the kayak, speed, stability, etc.
Other kayak design factors are materials (e.g. Polyethylene resin, fiberglass, etc.), manufacturing technology (e.g. rotational molding, thermo forming, cold molding, etc.).

Kayak design is a term also used to refer to the kayak’s form (type), such as sit-in, sit-on-top (SOT), hybrid and twin-hull kayaks.

Outriggers for W300 Kayaks

Some activities like sailing and fast motorized boating require extra stability.
Products called ‘kayak sail’ are of little practical use because you can’t use them to go upwind, which is your main reason for using a sail in the first place.
Therefore, if you’re thinking about W kayak sailing you’d need a canoe or dinghy sailing rig that can take you upwind and is powerful enough to make sailing fun. Because it’s powerful, such rig requires a stable boat, and that’s where the outrigger/s solution can be applied.

Similarly, you can outfit your W kayak with a small electric motor, in which case it would not necessarily require extra stability.
However, if you’re planning to motorize your W kayak with a powerful gas engine (1.5 horsepower and up) you’d need to consider increasing your boat’s stability because when going at high speed it would become unstable.

Generally speaking, adding a pair of outriggers provides more stability, but a single outrigger can offer sufficient stability while being more practical in other ways.
The first problem with having an outrigger on each side of the boat is that in certain cases it limits the passengers’ access to and from the cockpit, for example when docking.
The second problem is that if you’re fishing an outrigger can come in the way of your fishing lines, and in case you have outriggers on both sides your freedom to cast all around the boat will be limited.
For these reasons we recommend using a single, large size outrigger rather than two small ones.
Such outrigger should be as long as possible so as to add minimal drag. It should also be voluminous enough to provide the buoyancy your W kayak needs to be stable even in extreme cases. Being heavy enough and placed away from the main hull/s will make it useful when the boat leans to the other side. The outrigger’s hull should not be as high as the hull in order to prevent the boat from leaning on its side.
The distance between the outrigger and the boat should allow you to paddle comfortably – we recommend at least 4 feet (120 cm).
This illustration represents a good single outrigger solution:

Canoe and Kayak Market Trends in Recent Years

The (U.S.) National Marine Manufacturers Association (NMMA) is offering to download a preview of the abstract of its 2006 statistical report for download free of charge on this page: http://nmma.org/facts/boatingstats/2006/files/orderform.asp

According to this report the 2006 US market for canoes was a little over 100,000 units sold, at an average price of nearly $550 per unit.
The market for kayaks was over 350,000 units sold at an average price lower than $500.
The total 2006 market for canoes and kayaks was $233,000,000.

If I understand this report correctly the data take into account neither inflatable nor used canoes and kayaks, and they reflect a relatively stable market both in price and number of units sold in recent years.
A rigid entry level kayak costs between $300 and $500 while a touring, whitewater or fishing kayak can cost over $1,000.
It becomes clear from this report that entry level (a.k.a. ‘recreational’) kayaks constitute the bulk of the market in terms of units sold, since the average kayak price is within the price range of this category.

What else is it possible to deduct from this report?
Obviously, entry level kayaks differ from traditional designs mainly by their length to width ratio (L/W, or L/B). They are shorter and wider than traditional kayaks, namely slower and stabler.
This means that the overwhelming majority of U.S. paddlers are willing to sacrifice speed for stability, and that paddlers who practice the Eskimo Roll and put their trust in it as the main means of recovery are a rarity (by that I mean even less than a minority).
Entry level is in fact the norm, and contrarily to what touring manufacturers used to believe paddlers stay at that level and don’t ‘progress’ to the traditional, narrow designs. Progress is therefore represented by the stable designs, while tradition is represented by the (you’ve probably guessed it already) traditional designs…

And last but not least, it doesn’t take statistical reports to see that kayak fishing is the most active and fastest growing market in paddle sports and activities. Most kayak manufacturers have noticed this trend and offer a wide variety of extra wide kayaks (up to 42″, that’s over one meter), because fishing requires more stability than any other kayak related application.
In the same spirit, traditional paddling magazines and websites are increasingly preoccupied with kayak fishing and feature more advertisements for fishing kayaks than ever.

2008 W Kayak Models

(Added May 08, 2008) –

One of the typical things that happen with a good design is that after people actually begin using it they discover new advantages it offers, and new things it enables.

The 2008 model has already exceeded our initial expectations by offering two new positions:

Side-saddle , and Riding-over

————————————————————————–

Original post:

I guess many have asked themselves what made Wavewalk modify our kayak design in the 2008 models.
The answer is a bit long:
First, we wanted to do counter affect the rising cost of shipping, and cutting two inches from the spray deflector’s top resulted in a 10% reduction in the overall nominal volume of the standard package we ship to the customer.
Second, we’ve noticed that some people preferred a more rigid cockpit rim, so we made it broader, thicker and more robust. Now they got what they wanted.
Third, we wanted to help small children (5-6 year old) paddle without having to stand up, and lowering the spray deflector offers just that.
Fourth, we wanted to make it even easier to step into the cockpit and out of it, and that’s really where one can say ‘the best gets better’.
Fifth, we thought that a deep and narrow hull was a perfect place to drag a powerful and energetic fish into while it’s fighting to get free. Lowering the cockpit rim enables the W kayak fisherman to swiftly ‘drag and drop’ the fish out of the water and into a hull with minimal effort, and let the fish calm down a bit before being taken care of – without causing a mess on the deck or worse – in the fisherman’s lap.
Sixth, we realized that although capsize and deep water re-entries are quite rare we’d better offer the paddler a more comfortable way back in, and again – a lower cockpit rim was the solution.
Seventh, a lower spray deflector enables W paddlers to move the paddle faster from side to side whether they’re canoing or kayaking their W.
Eighth, well, we felt we needed to show something new…

To compensate for the 2″ of protection lost we equipped all 2008 models with a preparation for a cockpit cover.
This means that W paddlers can paddle the 2008 models in the surf or in fast rivers as well as in bad weather while being better protected than they were before.

About the Wavewalk fishing kayak

Note: This is the first review that Jeff had published on his Wavewalk 300, a series that was produced between 2004 and 2010. Read more recent fishing kayak reviews »

By Jeff McGovern

My nickname in the pest control industry is “Gadget” since I am always looking for the latest, greatest thing or making improvements to what is already out there.  My favorite part of the job is speaking to large audiences across the country and I always bring lots of “Show and Tell.”  I am no different when it comes to my passion-fishing.

Long before kayaks hit the fishing world here in Florida, canoes ruled the shallows in many areas.  When I started canoe fishing here in the 80’s, there were a number of folks doing it, but it wasn’t well publicized.  Then we discovered outriggers for canoes and things started to change.  I could stand up in my canoe and see the fish I was stalking.  Plus, I could go into water that was too shallow for a motor or into zones that were designated “no motor zones” like the ones near Kennedy Space Center.  I love my canoe, but I wanted something I could just toss in the back of the truck and go.  So we started shopping for kayaks.

We looked at sit inside, sit on top, rudder, no rudder, big, small, skinny, HEAVY.  My wife, Kate, is small and wanted something small and light.  I am not small.  I am 6’3″, 245 lbs. and have size 15 feet.  We started with two small sit insides.  I enjoyed fishing from them-even won a fully loaded 13′ sit on top kayak catching a winning flounder during my club’s tournament-but I missed being able to fish standing up.  My quest for a stand up kayak began.  Then one day, surfing the web, I found a video clip of a guy jumping up and down in a kayak.  I knew that I had found my dreamboat-The W.

I am not small. I am 6’3″, 245 lbs. and have size 15 feet.

The W has ruined me for other kayaks.  My wife will tell you that the fleet (did I mention we now have 5 kayaks?) stays on the porch and the W goes fishing every Saturday morning.  I do need to mention that there is a learning curve similar to learning to ride a bike when it comes to handling and fishing the W.  I was discouraged the first couple of outings-but then I got the feel of it.  Now I use it exclusively, even in tournaments.

When other yakkers stay home because of high winds, I’m out paddling around.

The W allows me to fish virtually all the time.  When other yakkers stay home because of high winds, I’m out paddling around.
In the W, your lower half is protected from the wind and the spray shield keeps water off you as well.   A set of Frog Togs ensures that you stay dry and comfortable all day.  I’ve spent as much as 5 solid hours in the W in cool weather and lots of wind.
Padding is easier and requires less effort than in a regular kayak.  I use a long stroke at a slower pace and have no trouble keeping up with longer kayaks that are using double the amount of short strokes.  The W’s height allows that and helps me.  Also, I “push” the stroke rather than “pull” it.  The high hand and arm push the paddle through the water with the lower hand only pulling enough for guidance.  This allows you to paddle longer because it’s less tiring.

The W also handles waves much better and far drier than other small boats and kayaks.  We have a number of large yachts on the Intercoastal that kick up huge waves.  Other kayaks and small skiffs get spun around or tossed badly.  The W rides it like my CraigCat-up and down without a problem.  Last week I found it also slips up and down over the backs of very large and too curious manatees.  The boat tipped to one side, but remained upright and we both went home with a story of the one that got away.

Fishing is a sport of tactical knowledge and a feel for the area you are fishing.  I own hundreds of rods and reels and have designed a few kayak/canoe rods. I also test new rods and reels for a number of companies before they go onto the general market.  The more you fish, the more specialized your gear gets.  The most important thing is to understand the area you are trying to fish.  I envision the travel patterns the fish use to get from place to place.  I think about where they can ambush a meal with the least effort or how the tidal patterns affect where they rest and feed.  I have to understand how the light hits the water and how I might be exposed or hidden by it.  The W allows me to move into their house and position myself to the best advantage.  I wish I could come up with a way to describe the feel of the W.  Sitting down, it’s like riding.  Standing up-well, until I figure some way to put floats on my size 15 feet and walk on water,
standing up in the W is the next best thing.

I would venture to say the W offers improved casting with any gear. From the riding position, I get more power with my casting and spinning because I can put my whole body into the cast and use my legs.
The solid feel of the boat gives you a great sense of security.
Netting fish is also easier because you can bring the net handle up and across the noodles and just hold in until you net the fish alongside.
This allows you to compose yourself and arrange things to remove the hook without tangling your gear or hurting the fish.  WARNING:  It is very important to fill the handle of your net with spray foam.  This is
so that when manatees and sundry aquatic creatures borrow your net, you can get it back.  I know from personal experience these critters are very inconsiderate and will leave it on the bottom where you can’t find it.
I would venture to say the W offers improved casting with any gear.
It’s a great exploration kayak and there’s a great sense of adventure for the user.

My favorite scouting position in the W is standing up.  I can spot fish and then move in stealth mode with a push pole or paddle blade.
There is a serious advantage to being able to stand and see over grass or oyster beds.  Being able to peak over cover is a big deal.
Sometimes, like when I was working my way along the Ocklawaha River, I was moving through snag (and gator) infested waters with logs, bed pads and deep, dark places you might not want to get into.  The W handled that
type of paddling better than our other craft.  You could stand quick to see ahead, duck and move around things.  It’s a great exploration kayak and there’s a great sense of adventure for the user.  No craft is perfect for all things, but sometimes I have so much fun with the boat, I forget to fish.
