It looks unique, for the first time I saw how fishermen park their boats by hanging boats on the shoreline. I think this is a tradition of fishermen who inhabit the coast of Sibolga or Tapanuli Bay, North Sumatra, common sight we encounter there.
Photos were recorded during the 'West Coastal Spice Route Expedition of Sumatra', with @Keuudeip as the research team leader, on 19 December 2020.
