What are the disadvantages of sea travel?

Answer:
Compared to air travel, sea travel is slower. A trip from the New York, USA to Christchurch, New Zealand typically takes 18 hours of direct flight, but if you travel by sea it might take you a month or so, thus wasting so much precious time while on transit. Another disadvantage is uncomfortable especially if you suffer from seasickness.
