sculling or sweeping?

There are two kinds of rowing: sculling and sweeping.

Scullers use two oars, one in each hand. Sculling boats are configured as single, double, and quad, that are rowed by one, two, or four people.

Rowing where each person has one oar (held by both hands) is called sweeping. Sweep boats are set up as pair, four, or eight, that are rowed by two, four, or eight people. Fours (most of the time) and eights (always) carry an extra person called the coxswain (or cox, for short). The cox is responsible for executing race strategy, steering the boat, encouaging the crew, and insulting the other boats in a race.

Both sculling and sweep rowing are Olympic sports. Essentially all Collegiate rowing is sweep rowing where larger crews can be assembled and trained. Sculling is more common in adult rowing because rowers can train and race individually, but they can also easily team up with another one or three rowers to row as a team. Twin Cities Youth Rowing is a sweep rowing program with a focus on teamwork and technique and preparation for college rowing.
