Single scull

A single scull is a rowing boat used in the sport of competitive rowing. It is designed for a single person who propels the boat with two oars, one in each hand.

Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section in order to reduce drag to a minimum. They usually have a fin towards the rear, to help prevent roll and yaw. Originally made from wood, shells are now almost always made from a composite material (usually carbon-fibre reinforced plastic) for strength and weight advantages.
