Something else. Rigging is the ropes holding the masts and controlling the sails. There's a bunch of weirdness going on with that. Someone with an interest in sail boats will spot it easily.
Comparing these rigs to modern ones with aluminum masts and stainless wire or dyneema rope is very apples to oranges.
Even more so since 97% of modern boats have Bermudan rigs (triangle sails) where as these ships have square sails.
