Sweep rowing is a style of rowing in which each rower uses one oar held with both hands, rowing on either the port (right) or starboard (left) side of the boat (rower perspective).
Because each rower only pulls on one side, sweep boats require paired or even numbers of rowers to keep the boat balanced. Common sweep boat types include:
Pair (2-) — two rowers, one on each side
Four (4-) — four rowers, two on each side
Eight (8+) — eight rowers, four on each side, plus a coxswain
The coxswain (cox) is a non-rowing member who steers the boat and coordinates the crew, and is most commonly found in sweep rowing.
Sweep rowing is often considered more of a team-focused discipline, since each rower depends heavily on their partner(s) on the opposite side to maintain balance and timing. It is the most common style seen in high school and collegiate rowing programs.
