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.




Kayak and Canoe Floatation and Stabilizers - What’s The Difference?

Thursday, March 6th, 2008

Those who know the difference are likely to ask themselves why bring up such a comparison when flotation and stabilization have nothing to do with each other. Well, this is true but some people tend to be confused by the looks of side flotation in certain canoe models and in the W Kayak.

For the benefit of these people we need to explain that indeed flotation and stabilization are two different functions:

Canoes and kayak are outfitted with flotation in various forms - from inflatable bags to closed cell foam. The flotation element/s is lighter than water and impermeable, and its purpose is primarily to prevent more water from getting into the boat in case it is strongly leaning sideways or turned over. Flotation can be applied inside and/or around the boat, and it is basically intended to serve as means of recovery.

Stabilizers are floating devices on the boat’s sides, and they touch the water nearly all the time. Their purpose is to prevent the boat from leaning too much sideways, and they do it by offering extra lateral buoyancy. Stabilizers contribute both to the boat’s initial (primary) and secondary stability, meaning that they enhance both the feeling of lateral stability as well as the actual stability of the boat. Stabilizers are also called outriggers and sponsons, and they act as means of accident prevention as well as comfort enhancers. Large size outriggers can in some cases increase the canoe or kayak’s load capacity.

The side flotation modules on the W Kayak’s sides are not stabilizers, and they never touch the water in normal conditions. Their function is the help preventing the W Kayak from completely overturning in case it capsizes, and simply help it float above the surface if it did overturn and water got in. In such case the location of the side flotation modules helps turning the boat back.

If the W Kayaker or kayak fisherman bailed out quickly enough and the boat leans strongly on its side without him/her pulling it down the presence of a flotation module under its side can make the W right itself without help.
