For me, one of the most compelling reason for the general form of  
Greenland style paddles is reliability. A long, narrow, relatively  
thick (for its width) paddle blade  is much less likely to crack,  
split or break than a short, wide relatively thin blade.

  While it is possible to make a short, wide, thin blade out of wood  
using primitive tools, it is very difficult to make one that will not  
split at the first impact with something. A wide blade that is not  
protected by a waterproof finish will warp, check and eventually split  
even without hitting anything. A long, narrow, thick blade will  
generally last a lot longer and is much less likely to split.

  The longer blade also distributes paddling loads over a wider area  
where a short, wide blade will have a stress concentration at the base  
of the blade where the blade necks down to the shaft.

  For a subsistence hunter with limited access to quality paddling- 
making materials, reliability alone would probably be sufficient  
reason by itself to settle on a paddle form.
