Single scull

They have riggers, which apply the forces exerted by the sculler symmetrically to each side of the boat and (usually) a fin towards the rear which helps prevent roll and yaw.

Recreational single sculls tend to be shorter and a little wider than racing boats and can have a slightly flattened hull shape to provide more stability.

Recreational single sculls can be made of a variety of materials including carbon fiber, fiberglass, wood or rotomoulded polyethylene.

[citation needed] The single scull is one of the classes recognized by the International Rowing Federation and the Olympics, who set the minimum weight of the hull at 14 kg (30.8 lbs): the average length is around 8.2 m (27 ft).

Powerful and accomplished sweep-oar rowers may be unable to demonstrate their ability in a single scull, where balance and technique are more critical.
