Kayak Paddle Length Vs. Kayak Width

Choosing the correct kayak paddle specifications can have a profound impact on your paddling performance. Small discrepancies in the length and width of the paddle can result in changes in boat speed, balance and level of fatigue -- especially when paddling over long distances. Consider several factors -- including your body composition, fitness level and style of paddling -- when determining the correct length and width of a kayak paddle.

Length

Kayak paddle length refers to the length of the paddle, measured in centimeters, from one tip of the blade to the other. As a rule, a longer paddle enables you to propel the boat forward at a greater distance with each stroke, but also requires more effort and may contribute to increased fatigue. A shorter paddle requires less effort, but does not provide as much distance per stroke.

Width

The width of a kayak paddle actually refers to the size of the blade. According to Australian Canoeing's "Flatwater Racing Manual," kayak paddle blades did not undergo much change in design until about the 1980s, when the "wing" paddle was introduced. The wing design differs from the conventional flat blade because its curved shape allows it to grab the water and prevents it from slipping from side to side. High performance wing blades are now used in most kayaking disciplines.

As with length, a larger kayak paddle blade contributes to increased boat speed, but requires more effort and can result in earlier fatigue. A smaller paddle blade requires less effort, but does not provide the same amount of speed as a larger blade.

Choosing a Paddle

The first step in choosing a paddle, according to the RoguePaddler website, is to select the blade size and style. If you're a flatwater sprint paddler, opt for a larger blade to promote maximum boat speed. If you're a recreational paddler, opt for a smaller blade to prevent fatigue. Next, choose the correct paddle length. A paddle is roughly the correct length when, standing next to the paddle and reaching one arm over your head, you can just barely curl your fingers over the top of the blade. If your entire hand is above the blade, the paddle is too short; if the paddle extends beyond your hand, it is too long.

Purchasing Tips

Once you have several hours of paddling under your belt, you may develop some individual paddle preferences. For example, if you tend to enjoy paddling at a higher stroke rate, you may want a shorter paddle with a smaller blade. If you like taking longer, more powerful strokes, you may prefer a longer paddle with a larger blade. Experiment with several paddle lengths and widths before purchasing a paddle. Also, opt for a paddle with an adjustable shaft so you can change the length later on.
