Kayak Side Flotation: Why Use It, and How Does It Work?

Thursday, March 20th, 2008

The 2008 W Kayak models come equipped with one or two pairs of detachable, side flotation modules. A flotation module is a 5 ft long plastic foam ‘noodle’ with a bungee cord going through its core. The bungee hooks at its ends enable attaching the module to Nylon eyelets on top of the W hulls’ tips.

The side flotation modules are essentially recovery accessories: In case you capsized your W kayak they can help preventing it from overturning, and if your kayak is overturned they help keeping it afloat, and by that make it easier for you to turn it back.

In some cases, when your W kayak is laying on its side, the presence of a single flotation module or better - a pair of such modules under the top side of the lower hull can lead to the boat righting itself, and this is how it works:

The top part of the lower hull is prevented from sinking by the presence of the side flotation module ‘A’.

The flotation module helps keeping water from from getting in by pushing the cockpit rim above the surface.

If water gets into the lower hull through the cockpit opening it will flow to area ‘B’ and make this part of the boat heavier. By making it increasingly heavy it would make it tilt and regain its normal position - that is with the cockpit opening facing upward.

If your W Kayak doesn’t right itself in such a situation it’s easy to right it by unbalancing it.

It’s clear to see why in any case outfitting your W kayak with two pairs of such flotation modules is more effective than outfitting it with one pair.

In sum, whether you’re taking your W kayak on a paddling, camping or fishing trip, it makes sense to take preventive measures that can minimize the severeness of a capsize accident by outfitting it with side flotation modules.

Whether you’re taking with you on board fishing tackle, camping gear or other stuff - it’s always a good idea to secure this equipment by attaching it to the boat. You will find there are plenty of spots inside the cockpit that you can use to attach bungees, carabiners, hooks and rope to secure your gear.




Getting Trapped in a Kayak

Tuesday, January 29th, 2008

Kayakers call this type of accident ‘Entrapment’ (which in regular English is a juridical term…)
However, in the world of kayaking entrapment is described as a situation where the paddler’s lower body, or a part of it (E.G. leg, foot) is caught inside the hull while the kayaker is trying to retrieve it from there during a ‘wet exit’, that is while attempting to leave his or her kayak and swim.
Imagine yourself in turbulent water, your kayak overturned, you’ve been ‘pumped out’ of it (by gravity) or you’re just trying to perform a ‘wet exit’ - and you’re ‘entrapped’.
It’s not merely a stupid situation - it’s actually a very dangerous one.

How can such thing happen?
It’s a fact: Whitewater, sea and surf kayakers who paddle monohull sit-in kayaks (SIK) attach themselves to their boats with a watertight accessory called ’spray skirt’. This garment is made from strong fabric, usually Neoprene reinforced with  rubber, and it’s tightly secured both to the kayak as well as to the paddler’s body by various mechanical means in order to prevent water from leaking in, or the skirt coming out of its place. Being well secured is especially important during a recovery maneuver that such SIK kayakers perform called ‘Eskimo Roll’ - when their kayak is upside down.

As in other outdoor sports the rule of thumb in kayaking is ‘Stuff Happens’. Since kayaking accidents are by definition events characterized by the reduced control the kayaker has over what’s going on, it can happen that SIK kayakers remain attached to their kayaks against their will, I.E. they are ‘entrapped’ inside to some degree.
Such situations are particularly hazardous if the accident occurs in turbulent water (E.G. big surf) and ‘rock gardens’ (beaches with underwater rocks), which is often the case.

Why am I talking about this?
W Kayaks are not equipped with such spray skirts, and W kayakers don’t perform Eskimo Rolls, and so far no one has ever reported any W Kayak accident involving any degree of ‘entrapment’.
Nevertheless, I feel it’s important to explain this issue and discuss it because it highlights the necessity for accelerating the paradigm shift in paddlesports safety: Most paddlers today wouldn’t even consider using kayaks equipped with spray skirts anymore, and they have chosen to paddle stabler kayaks rather than ones requiring paddlers to have a ‘Bomb Proof Eskimo Roll’ (I.E. 100% reliable under all circumstances).  In other words, people have generally voted against those sit-in monohull kayaks (SIK) that demand a high level of expertise in this overrated recovery maneuver that too few people can actually depend on.  The problem is that too many kayakers out there still use that type of spray skirt without possessing a ‘Bomb Proof Eskimo Roll’, and by that are exposing themselves to the danger of being ‘entrapped’ in their kayaks.

Choosing a Good Beach For W Surf Kayaking

Wednesday, January 23rd, 2008

If you visited Wavewalk’s website you’ve probably noticed that unlike regular surf kayakers W surf kayakers don’t wear helmets. This is because we choose our beach carefully and try to avoid playing in places where underwater rocks or other submerged objects are to be found.
Traditional surf kayakers must wear a helmet because they constantly roll they boats so they could get head injuries even without hitting a rock. Board surfers don’t wear helmets because whenever they lose balance they simply jump overboard. In this sense W kayak surfing is more like board surfing, although we go overboard much less often…

Another thing you want to avoid is to portage your W kayak over long distances. If you must do it try to choose the beach that has a parking lot that’s closest to the beach because you can drag the boat on sand and pebbles, but it’s not advisable that you do it on asphalt or concrete - In fact it would damage your W kayak in the long run.

You also want to avoid a beach that’s too crowded with bathers since paddling among them might lead to accidents.

Generally, a beach where you can see many board surfers could be a good beach for you.

Paddling and Kayak Fishing in Cold Water and Weather

Tuesday, January 15th, 2008

‘Cold’ is relative of course, and what I mean by it in this case is temperatures below freezing or close to that.

Sometimes you can find open water on a frozen river or lake, and since it’s possible to launch your W kayak from ice as well as to beach it on ice the question is ‘why not go paddling or fishing?’

The simple answer is ‘because it’s very dangerous’.
In other words, the combination of ice and cold can turn out to be deadly.

Some of the factors that contribute to making such activities more dangerous are:

Air temperature: When it’s below freezing your paddle can get covered with a layer of ice and become heavy. The water dripping from it on your kayak can freeze and form a heavy layer that might destabilize it. If the water freezes inside the cockpit you might slip on it, lose your balance and fall overboard.

Alcohol: Absolutely not. Drinking while you’re paddling or fishing in cold water or weather is taking the first active step towards an accident. There is a strong correlation between drinking and paddle fishing accidents. If you need to boost your energy while you’re kayaking or kayak fishing do it with hot coffee from a thermos bottle, chocolate or energy bars.

Cellphones are an absolute necessity in order to call 911. BTW, a wet cellphone is useless…

Children. Too dangerous: being smaller children have a bigger surface area by relatively to their volume, which means that if they fall in the water their body temperature will drop faster than that of an adult in the same condition. Children also have a tendency to be careless (at least those that I know…) and panic easily - two potential hazards that you don’t want to have to face.

Clothing: Boots, heavy shoes, waders and heavy clothing are an absolute no. A good wetsuit or dry suit and booties are a must.

Distance from shore: Don’t paddle or fish where people on shore can’t see you. Preferably, they should also be able to hear you. Carry a whistle with you.

Number of people with you: Paddling or fishing in cold water all by yourself is really careless. If you feel you must do it you should go with a group, preferably with people who know what they’re doing and could advise you on what to do and not to do, as well as help you in case something happens. It’s also a good idea to have a bigger boat, preferably a motorboat as part of your expedition - stuff happens.

Saltwater. Ocean water with typical salinity freezes at about 28.9°F (-1.8°C), which is a colder than the freezing temperature for fresh water. This means that sea water that’s partly covered with ice is likely to be colder than fresh water in a similar condition. This means it would be even more dangerous if you fell overboard.

Time of day: Winter days are shorter, which means that you might find yourself trying to paddle your way back in the dark, which is dangerous both because it increases the risk of an accident as well as reduces the chances of you succeeding in rescuing yourself or getting rescued by others.

Type of boat: Reducing your degree of exposure to the elements is a good idea when kayaking or fishing in cold water and weather.
The worst are sit-on-top (SOT) kayaks that put you close to the water without any protection. Sit-in kayaks (SIK) can be a little better since they offer you the opportunity to protect yourself with a spray skirt, but using such an accessory is hazardous if you don’t have a fool proof Eskimo Roll (very few people do), and it’s highly inconvenient for fishing. Canoes offer good protection from spray but paddling them can become too difficult because of windage problems. Finally, W kayaks offer you the best protection from both spray and wind, and they also perform better than the other boats under wind.

Water depth: Getting out of deep water is far more difficult than it is from shallow water. Falling in deep water can cause hypothermia faster than it would take you to rescue yourself, which means that your chances of survival might be slim.

Wind: The combination of wind and sub freezing temperatures can lead to the formation of surface ice where you had open water before. This means that on your way back to shore you might find yourself tired and shivering in your boat without being able to paddle through the newly formed ice.

Your physical condition: Some people are in great shape and can resist cold, but are you one of them? Remember - water is about 700 times denser than air, which means that it can cool your body instantly and lead to heart failure even before hypothermia settles in.

So, if you still feel you must get out on a cold winter day it’s better if you kept your kayak at home and found something as rewarding as paddling or fishing to do, yet not as dangerous.
