Editing Racing shell (section)

===Riggers===
A narrower boat provides a sharper angle to the bow and a smaller cross-sectional area reducing [[drag (physics)|drag]] and [[wave making resistance|wave drag]], and avoiding [[hull speed]] limitations at race speed. The first racing shells, while narrower than working rowboats, were limited by the width necessary to mount the oarlocks on the boat's sides ("[[gunwale]]s"). By attaching outriggers to the gunwales, the oarlocks could be placed farther out. This resulted in two things: oars got much longer, providing more length to the strokes, and hulls got narrower until they were as narrow as possible while still retaining sufficient buoyancy and balance.
