A new program launched this month offers subsidized housing on land for people currently living aboard boats anchored off the shores of Sausalito. Most of the scrappy sailors, known as “anchor-outs,” don’t want to leave the free anchorage and their nautical lifestyle to become landlubbers. But the promise of long-term housing seems to be softening the blow, at least for some. They are resigned to giving up their boats on Richardson Bay, beaten down by the years of battling local officials hell-bent on dismantling the anchor-out community.
