What is a great disadvantage to the Hanseatic leagues sea routes?

A significant disadvantage of the Hanseatic League's sea routes was their vulnerability to piracy and naval warfare, which could disrupt trade and threaten merchant ships. Additionally, reliance on maritime routes made the league susceptible to adverse weather conditions, which could delay shipments and impact trade stability. This dependence on the sea also meant that any political conflict or changes in alliances could jeopardize their trading operations.
