The Hawi Standup paddle was designed after the Tahitian style blade, putting more surface area down at the bottom of the blade to allow a good bite when you enter the water. I went with a very slight scoop on the bottom of the blade to make the catch a little easier but not so much that it holds water and makes the exit sticky.  A 10-degree angle provides easy entry and a forward angle to the blade. The top of the blade is a little thicker than most, allowing it to counter cavitation and keep solid water on both sides of the paddle. The small dihedral on the back helps keep the paddle from slipping laterally through the water during the pull phase and yet is subtle enough to not affect the exit. 

On Standup Paddling Technique:

With standup you have lots of leverage and weight that you can put on a paddle. Setting the blade at a forward angle is the foundation of the stroke, but the approach angle needs to be accomplished by rotating and not bending the top arm. The set is crucial and needs to be subtle yet deliberate and the pull phase shouldn’t happen before the blade is locked. The rotation should start once the blade is locked, not before. The [strait] bottom arm and lat (latissimus dorsi) should be the muscles used first.  You can use your body weight with your top arm as well if you have enough load on the blade.  Your legs should engage as you pull through the water and allow the hips to push forward slightly for a little more power. Exit should be clean and approximately when your elbow reaches your torso. Recover should be relaxed, smooth and not rushed.
