In Olympic Windsurfing 'One Design' boards are used. All sailors use the same boards, daggerboards, fins and sails. The equipment is chosen to allow racing in a wide range of sailing conditions. This is important for the Olympic Games, as events have to take place regardless of whether there is enough wind for planing.
The Neil Pryde RS:X is the current Olympic class which was used for the first time in the 2008 Summer Olympics.
