Like any other mode of transport, water transport has its share of advantages and disadvantages.
Advantages
Low Maintenance Cost
Since the tracks in water transport are natural and free, there are no track maintenance costs associated with rail and road transport.
It is Affordable
Compared to other means of transport, water transport is relatively cheap.
Ideal for Moving Bulky Goods
Water transport is the preferred means of transport for moving bulky goods over long distances.
Useful in Times of Natural Calamities
During natural disasters such as floods, road and rail transport is inaccessible. Water and air transport become an 
alternative option for relief operations.
It’s Used for Defence
To improve a country’s naval defense, it becomes essential to develop the shipping sector.
Supports Foreign Trade
Water transport plays a vital role in facilitating international trade. Foreign trade in most countries depends on water transport.
Disadvantages
Below are some of the downsides to water transport:
It is Slow
Water transport is the slowest among all other modes of transport. The speed of water transport depends on natural occurrences such as the monsoon winds.
It’s Riskier
There have been many cases of boats and ships sinking deep into the oceans, seas, and lakes. This result is a loss of lives and resources.
