Marine spatial planning (MSP) has been lauded as a remedy to unsuitable marine management. There is, however, growing MSP research illustrating that it is failing to foster paradigm shifts towards sustainable governance. The gap between MSP theory and practice is due to its asocial and apolitical implementation. This narrow version of MSP has been advanced through post-political planning and uncritical rationalities. The result is a choreographed form of MSP, with clearly defined outcomes that serve the needs of elite actors rather than the public interest. This chapter argues that to recapture its democratising potential, MSP requires explicit engagement with politics and power. We highlight the use of the boundary object lens and citizen science as two potential avenues to facilitate this engagement.
