Views on unmanned or autonomous ships have evolved tremendously. A few years ago, what we considered utopian is becoming not just a vision but also reality in the form of different development projects. A large publicly funded initiative on autonomous waterborne applications (AAWA) was recently conducted in Finland. This paper will focus on the outcomes of this initiative from the perspective of stability and autonomous ships. The paper will also give a review on the rules and regulation situation regarding autonomous ships and stability.
