Ropes can be adjusted if river levels change chains cant . I know last year that other boaters adjusted my ropes when i left Cuchilo for a week because the river was flowing to fast to put her back on her mooring . Fair point chaining a dingy up and leaving it swinging but anything bigger .... Saying that i noticed a NB at Sunbury has chained him self quite tight to a mooring ring , i was always told never to chain a boat up
