Slide 4:

long, narrow, and broadly semi-circular in cross-section in order to reduce drag to a minimum. Made from carbon- fibre reinforced plastic) for strength and weight advantages. sliding seats to allow the use of the legs in addition to the body to apply power to the oar. There is presence of hydrodynamic drag and aero dynamic drag Continuous movement of the hands and the legs, they should be kept at a certain angle and certain posture must be remained
