I asked Todd Bradley from C4 Waterman to let me film him talking about the stand up paddle to share the fundamental information with everyone. I got a lot out of his explanations and hope it can help others.

Todd Bradley: Shape is super important. There’s a lot of blades. Some of them just go straight out like this and they have a lot of shoulder in them. The reason why we don’t design it with shoulder is because if you look at the board like this, and the same is true with canoes, what we’re trying to do is – just like a prop on a blade, you don’t have the prop sitting on one side of the boat because the board will turn one direction. What you try to do if you have a single prop is you try to put the propeller of a motor boat is exactly on the back center of the boat. So the same is true with the paddle. What we’re trying to do here is you can see that the way the paddle is designed is to get as much of the blade towards under and towards the center of the board. So then you’re more efficient through the water and your board wants to pull straight. Again, if we’re paddling now Evan and we have our blade right here out of the water, how efficient are we and how close are we to the center where the best power is? That’s one of the reasons why a lot of people broach on their paddles when they take strokes, because they’re either sweeping from the outside, which is going to swing the board around, or they’re not putting the blade all the way in to the water and they’re running it by like this, it’s banging the rail and it’s not efficient because you’re not getting the blade in the center portion of the board where you need to get the best power possible, the most efficient power possible.
