Maybe someone can help me with my ignorance here, but...

Just how important was speed to the Aleuts, Inuits, etc.? Were they
really set on shaving off that extra half second on their 100 meter
sprints? It just seems to me that laminar flows and "bubblers" would
really only interest someone who races competitively. But maybe I'm
wrong. I guess if a perfectly fast boat made a lot of difference while
persuing animals during hunts then I can see why it would be important to
consider such designs.

Any thoughts?
