A common misperception is that sea kayaks require extensive “rocker” or extended-bows to perform well in waves or rough water conditions.

 

First, let’s look at the difference between rocker and an extended bow – these two terms are often confused.

 

Rocker is the amount of curvature along the keel of a boat under the waterline. Once the hull rises above the water level, any additional length is Extended-Bow (or sometimes Extended-Stern).

 

Extended-Bow is a length of bow protruding forward in front of the kayak, above the waterline.

 

Many people mistake the look of an extended-bow for rocker. See the attached photo for a comparision of the differences. Epic kayaks have ample rocker, but minimal extended-bow. This gives our boats a maximum waterline length, which has proven to be more efficient in all water conditions.

 

It’s a myth that extended kayak bows (or sterns) are required for good performance in waves. This myth is perpetuated because many older sea kayaks (based on Aleut , Greenland or British style designs) have extended upswept bows.

 

Assuming that sea kayaks should have extended upswept bows because that’s what older kayaks have, is like assuming that automobiles should crank starters, block shapes and minimal suspension because that’s the way the first cars were built. Would you rather drive a model T or a modern automobile with aerodynamic shape, electronic ignition and a host of other innovations? Sure, a model T can be fun if you’re into history, but most people will be better served by a modern car that is faster, handles better and is easier to drive. Likewise a modern Epic kayak will make your paddling easier and more fun.

 

This myth was proven false in open ocean kayak competitions. 20 to 30 years ago, most competitive open ocean kayaks (or surf skis) had extended-bows – people assumed these would perform better in open ocean waves. As the competition has gotten stronger, designers have realized that extended-bows are not needed, and that kayaks perform much better in wave conditions with a full waterline length and relatively plumb bows. The same has proven in modern sailboats.

 

We’ve found that extended-bows simply poke into the wave in front of the kayak, while providing very little buoyancy. When the wave hits further back in the boat where there is more volume, this causes the kayak to pitch upward. As the wave passes, the kayak then slams down, creating a large splash and a significant loss of performance.

 

With a plumb bow and full waterline length, the bow gradually lifts as it approaches the wave, and lands more gently. The longer waterline length gives a much more efficient hull and the kayak performs better in all conditions.

 

We challenge other kayaks to go side by side with Epic in rough water conditions. In fact we're having a hard time finding comparisions, as most of our competitors don't want you to see this!
