Joe Kloc spent nine years immersed with Richardson Bay’s “anchor-outs,” a community living on abandoned vessels just offshore from multimillion-dollar Sausalito homes. In his book “Lost at Sea,” Kloc chronicles their struggles against the authorities and residents who ultimately dismantled the century-old floating community. Kloc captures the anchor-outs’ resilience amid displacement, exploring what happens when society pushes its most vulnerable members to the margins.
