Finding its roots in centuries-old stories of urban water squatters and haphazard water craft builders, Mare Liberum is a collaborative exploration of what it takes to make viable aquatic craft as an alternative to life on land. The project draws from sources as diverse as the ocean-crossing raft assemblages of Poppa Neutrino, improvised refugee boats built in Senegal and Cuba, and modern stitch-and-ply construction methods which make complex, traditional boat designs approachable by novice builders.
