Directory of articles on the subjects of ergonomics, back pain, and kayaking

Back pain is the number one source of disability among adults in the United States.
This fact is closely related to overweight and what is often referred to as Sedentary Lifestyle, namely too little physical activity.

Back problems encompass a wide range of symptoms and medical conditions, and they all make it harder for people to enjoy paddling ordinary kayaks that feature the combination of a low seat and footrests that force the user into a non-ergonomic (uncomfortable) position known as the L-posture.
In this posture, the kayaker's legs push their feet forward against the footrests and at the same time they push the lower part of their back known as the Lumbar Spine against the seat's backrest. This is an uncomfortable posture for anyone who has a sensitive back.
People who suffer from back problems and disabilities cannot and should not paddle in this posture.
Symptoms often include tickling in the legs, and leg numbness. Sometimes kayakers are prevented from getting out of their kayaks because they temporarily lost the sensation in their legs, or suffer from cramps.

Another problem that traditional kayaking may cause is pain and inflammation resulting from the pronounced and repetitive torsional movement of the paddler's torso. In the long run, this too can lead to more pain and disabilities.

Pedaling pedal driven kayaks still requires the user to be in a posture that exerts abnormal and unwanted pressure on their lower back, and as such it should be avoided by people with sensitive backs.

Paddling in other postures does not lead to such problems, and Wavewalk's kayaks are back pain free, since they offer their users to sit on a high saddle, with a leg on each side, and paddle without abnormal pressure on the spine. These kayaks are back pain free.

This blog offers many articles and testimonials on these subjects, as well as other ergonomic issues.

Good ergonomics, namely no back pain in high speed motor kayaks going in rough water

The faster you go, and the rougher the water you drive in, the harder it is on your back.
This is especially true for your lower back, and it can be true by extension to your legs, your shoulders, your knees, your neck, etc.
To make a long story short, the boat you drive in the chop must be adequately equipped with seats that allow you to withstand the shocks, and balance yourself easily and efficiently. A motorized kayak or boat that does not offer ergonomic seating is uncomfortable and potentially hazardous. Driving it for more than a short period of time will cause fatigue, discomfort, and possibly even back injuries.

Take a look at this demo movie that shows a middle aged and non athletic guy driving a Wavewalk S4 kayak powered by a 9.8 HP outboard motor, at full throttle, in rough water, in the ocean - The secret of this exceptional performance is in the patented twin-hull form, combined with the saddle seat that's similar to the seats found in large-size personal watercraft, ATVs, and snowmobiles, all of which are high performance vehicles suitable for tough conditions -

Big and heavy guy in motorized fishing kayak - No back pain, no discomfort, just fun

Back pain is the number one source of disability in the United States, and the majority of adults in this country are overweight. Coincidence? Surely not  -
Back pain and excess weight are strongly correlated, and the more unwanted weight one gains the more they're likely to experience back pain and suffer from related disabilities.

So what's a 330 lbs guy to do if he loves fishing and boating?
Paddling a SOT or sit-in kayak is out of the question, obviously, because it requires sitting in the non-ergonomic posture known as the L position, which creates discomfort, back pain and sometimes even leads to back injuries.
Fishing out of a Jon boat or a small skiff isn't a solution either, because these boats aren't particularly comfortable, and being heavy too, they're not easy to handle during launching and take-out.

The solution? - A new portable (car-top) boat that's as lightweight as a big kayak, more stable than many regular motorboats, and more comfortable. This patented, twin-hull (catamaran) skiff kayak is the new Series 4 (S4) from Wavewalk.
The S4 weight a little less than 98 lbs without accessories, and it paddles better than most kayaks out there.
The S4 features a saddle seat similar to the seat of a large-size personal watercraft (PWC), which unlike kayak seats induces no back pain.
When driven with an outboard motor, the driver can ride the S4 in two comfortable positions -
The first position is Riding, namely facing forward with a leg on each side of the saddle, on both sides of the body. In this posture, the driver's legs support their upper body naturally and most effectively, and provide the most intuitive and efficient means for them to balance themselves.
The second position side-saddle, namely with both feet in one hull, and the user facing the side of the boat.
Both these postures are pain free, comfortable for the back and the legs, and allow for full control and stability in the S4, in driving as well as in fishing, as shown in this video -

Big Guys, Heavy Guys, Elderly Guys, Disabled Guys... - Back Pain and Kayaking Don't Necessarily Go Together Anymore

Being a big guy almost always means that you're going to feel uncomfortable sitting in a kayak, whether you just paddle it or you also fish from it.
The same is true if you're overweight - Being seated in the notorious L position is definitely not going to make you happy.
And if you happen to be elderly, you're probably going to avoid paddling kayaks and fishing out of these uncomfortable and tippy little boats.
Being disabled is tough enough, without having to balance yourself on top of a kayak, or having to struggle with getting in and out of it, as well as experiencing back pain.
Well, it's all true for Sit-In Kayaks and Sit-On-Top (SOT) kayaks, but it is definitely not the case with Wavewalk kayaks and boats, which are tiotally back pain free, even if you fall into one of the above categories, and even if you fall within all of them, as this elderly, big heavy and disabled fisherman from Texas explains in his comprehensive Wavewalk 500 review -

"I am 61, 280lbs, retired, 100% disabled, veteran Navy Officer.
I have a very bad back resulting from damage done while I was on active duty. My back has 4 bad disks in the lower end, three bad disks in the neck, and pinched nerves going to my legs. Added to this I suffer from Fibromyalgia. My meds for the most part keep the pain at a semi-manageable level, but the hurt never goes completely away. If I can help some other Vet or civilian with frequent orthopedic pain be able to enjoy kayaking it’s good enough for me....   - Before I found the Wavewalk 500, kayaking was beyond my capability."

Good news that should give hope and relief to many people!
