A servo for the rudder is the only electromechanical component in the plat- form required for sailing control. An optional thruster can be added for navigation out of harbors, away from hazards, or to augment control in low wind conditions.

A key feature of the SSS platform is that it can take vari- ous form factors and is highly scalable. A catamaran version demonstrated that it can sail above or below the water and, while on the surface, can perform missions such as deploy- ing and/or recharging unmanned aerial systems or to deliver
