Spreading Out Surface Area
Both these paddles have similar surface area. Inuitive allows you to fully submerge the blade into the water at a lower angle as useable paddle area is spread over the shaft. Traditional paddles require you to lift at higher angles. Less work for you = conserved energy.
Tradition vs Technology
Developing the sections of the paddle to loft across and create a 3D Form for CNC Machining of Red Western Cedar. Aknowledging this wood's highly oily material properties makes it fitting for water exposure.
