Human powered submersibles require that the designer employ all those techniques which optimize speed and control within the constraints o f the rules. Propulsion efficiency coupled with low drag are prerequisites. The field of options quickly narrows to include only thrust devices offering the highest efficiencies at very low power levels. This implies large diameter propellers with many optimally shaped blades. Additiorially, the ability of the propulsor to generate control forces as well as forward thrust eliminates the need for drag producing control surfaces. Body shape consistent with containing two people and having minimum drag points directly to laminar flow designs.
