The habit and the pleasure of using a traditional Greenland paddle may make us forget that this "tool" works because it responds to mechanical and physical principles just as the modern paddles! So, as with modern paddles, we can have very different results by varying the shape and material.
We all know that among the modern paddles, the yield of a paddle-bought at 30 € is not the same as a carbon paddle spoon used in competitions. Expert athletes are also differences between different brands of paddles to spoon, not to mention the measures of the amplitude and swirl of the spoon itself. In essence, the experienced athlete you choose the paddle on the basis of its preparation, the type of competition to the vessel and I would add, type "sea", we are talking about sea kayaking.
Returning to traditional paddles, I can say with certainty that we have almost never had the chance to choose according to their actual performance and effectiveness. Their craftsmanship and the fact that matches the wood you get beautiful objects "art" has often distracted! The Greenland paddle is still a "paddle", which can be functional or not, with the only difference compared to modern, effective or not effective ... always costs so much!
The luck I've had a lot to prove paddles philological construction, "reconstructed", both for normal use, or just for study by Piero Nichilo (PN KAYAK), allowed me time to be able to combine different forms, different behaviors, apparently their beneficiaries, Inuit and Aleuts sought according to their needs, characteristics and different yields. One thing in particular caught my attention, some paddles, are faster than others, or some have more support and more, but more importantly, that certain characteristics are antagonistic! Then be "refined" and more importantly "used" to create the right balance.
At this point, paper and pen in hand I made to calculate it, because everything has a mathematical correspondence! Dusting off those little knowledge of fluid dynamics and more particularly in aerodynamics (because of my job), so I say "understand", at least in part, is practically, our predecessors applied when building a specific type of paddle rather than another . Concepts that we often exchanged with Piero and got the "form". Ditto when I proposed the construction of a paddle specifically to compete, or at least, to recover that gap which affects the efficiency of Greenland paddles when used at maximum thrust that is in the race.
This new paddle design is to become reality, Piero Nichilo gave shape to the idea and the prototype has already been used and tested! Difettuccio lifted slightly, the paddle is too rigid (but will be changed to retrieve the matching elasticity of the wood), tools in hand, you retrieve an old sea kayak for almost thirty pounds, about 0.4 to 0.6 km / h with a stroke rate of 20-30% less. Obviously, to push it to its limit athletic training I think is important (here I am a bit 'scarsuccio!), How important it is combined with a fast kayak, everything ... just like the paddle with a spoon!
