Every Friday, a small group of congregants attends Rabbi Greg Wall’s class, “Adrift in a Sea of Talmud,” aboard a 23-foot sailboat named Enough, which is owned by a member of the Beit Chaverim Synagogue of Westport/Norwalk. The synagogue prides itself in welcoming Jews, no matter what their level of observance is. The notion of holding a floating Talmud class is consistent with Wall’s past efforts to find new ways to connect Jews with Judaism. It’s an approach that involved many music events during his tenure at the Sixth Street Community Synagogue, in Manhattan’s East Village, from 2009 to 2012.
