===Sliding rigger===
The same advantages may be obtained by fixing the seat and mounting the outriggers on rollers. Now the athlete's body mass remains stationary and the boat doesn't pitch bow to stern nearly as much. This improves the boat speed significantly.<ref name="Bill Miller 2000">{{cite web |url=http://www.rowinghistory.net/resources/equipment

In 1981, the German [[Peter-Michael Kolbe]] won the [[International Rowing Federation|FISA]] World Championship using a sliding rigger. In August 1983 FISA banned the use of the sliding-rigger, presumably because it was thought to be more costly than sliding-seat boats.<ref name="Bill Miller 2000" />
