Anybody else out there notice just how well the natural hulls move through the water? I could be wrong but my take on the matter is the slight imperfections and the fact that the surface tends to hold liquid close to them provides a layered effect as the vessel moves through the water. I've only done a preliminary search but nowhere have I found this mentioned so far. I may be way off base here but my gut feeling is it's because of laminar flow.
