What are Disadvantages to the Hanseatic league sea routes?

The Hanseatic League's sea routes faced several disadvantages, including vulnerability to piracy and naval conflicts, which could disrupt trade and endanger merchant vessels. Additionally, reliance on maritime routes limited access to inland markets and made them dependent on favorable weather conditions. The competition from other emerging trade powers and shifting trade routes also posed significant challenges to the League's dominance. Lastly, the need for constant maintenance of ships and ports could strain resources and logistics.
