RACINGSHELL
Racing shell
In watercraft, a racing shell is an extremely narrow, and often comparatively long, rowing boat specifically designed for racing or exercise. It is outfitted with long oars, outriggers to hold the oarlocks away from the boat, and sliding seats. The boat's long length and semicircular cross-section reduce drag to a minimum. This makes the boat both fast and unstable. It must be actively balanced by the rowers to avoid tipping. Being able to balance, or "set" the boat while putting maximum effort into the oars is therefore an essential skill of sport rowing.The above text is a snippet from Wikipedia: Racing shell
