In From Survival Cannibalism to Climate Politics (2025) as well as in Law and Politics from the Sea (2024) Mann proposes the ‘commonist lifeboat’ as a political metaphor for the age of climate change. This response to Itamar Mann’s re-reading of Regina vs. Dudley and Stephens proposes a materialist reading of his political theory of the ‘commonist lifeboat’, arguing that the lifeboat may be a metaphorical and practical site from which alternatives to our current ways of doing and thinking about politics in times of climate crisis might emerge. The text brings Mann’s lifeboat into conversation with my own and other scholars’ work on radical vessels – historical and contemporary – in order to demonstrate and expand its analytical capacity as a more-than-metaphorical term. Building on Mann’s use of the lifeboat as a metaphor and a site of maritime custom, I propose to understand the ‘commonist lifeboat’ also as a material container that operates in a specific material environment: the sea. I argue that a focus on the materiality of the sea and of the lifeboat may point to political practice, community and customs yet to be invented, which may help us navigate the turbulent political environment of our time.

Lifeboats are essential life-saving equipment for all types of water-going vessels and offshore platforms. Lifeboat simulators have been created specifically for offshore personnel to practice in conditions that are normally too risky for live training. As simulation training is a relatively new alternative, there is a need to assess how training performed with a simulator compares with conventional training. This study was performed to evaluate how skills acquired with different training approaches transferred to an emergency scenario. Over a period of one year, participants received quarterly training in one of three ways: using live boats, computer-based training or a simulator. Following training, participants were evaluated on their ability to launch and manoeuvre a lifeboat in a plausible emergency. The study results suggest a benefit to performing training with realistic lifeboat controls and practicing using representative emergency scenarios. Insights are provided on how training can be modified to increase competence.
