Chile discussed the inclusion of the concept of maritorio in their new Political Constitution. This complex dialogue has opened space for debating the relation among oceans, society, and the State. Following a systematic review of the literature, we examine the history, meanings, and uses of maritorio. Our analysis interrogates the ‘coloniality of power’ at sea, approaching maritorio as multiple and complex ‘more than-wet ontologies’. Drawing on the political debate on maritorio, we call for a relational and pluriversal politics of marine governance that is committed to dismantling the colonial and ahistorical configurations of ocean spaces and peoples. We argue that this requires learning from and working with/for ocean, water and fisher peoples, supporting their self-determination, autonomy, and sovereignty struggles. Thus, contributing to the myriad of place-based and global relations of solidarity, care, and reciprocity that feed into the pluriverse of ocean worlds.
