Main disadvantages of water transport are as under.
1. Limited Area:
Area of water transport is restricted. Rivers and oceans are free gifts of nature. Accordingly the operational area remains fixed. Unlike railways and roads, man cannot construct waterways.
2. Slow Speed:
It is a slow means of transport. Failure of monsoon results into fall in the water-level of rivers making navigation difficult.
3. Less Safety:
As against other means of transport, it is less safe. Danger of sinking of boats and ships always looms large.
