Traditionally made from hemp, the yarn was impregnated with "Swedish tar" for durability. While wood tar washes out after a year, it provides water and UV resistance until then. To maintain efficiency, apply oil or wax reproofing cream. But how does a rope with these two characteristics work and what extra capabilities does it have?
