What are tugs and barges?
Barges, on which cargoes are shipped, are usually non self-propelled and therefore dependent on a tug for propulsion; where the tug is the prime mover for the barge, connected to the barge using a towline. Distance between both can reach 200 metres and more.
What is the difference between a barge and a tugboat?
is that barge is a large flat-bottomed towed or self-propelled boat used mainly for river and canal transport of heavy goods or bulk cargo while tugboat is a small, powerful boat (a “tugship” in other languages) used to push or pull barges or to help maneuver larger vessels.
What kind of boat pushes barges?

How are tug boats so powerful?
Most tugboats are still powered by diesel engines. Many newer and larger tugs have two diesel engines, some with a combined total of over 6,000 horsepower! There are also hybrid tugs that combine diesel and electric power, and LNG-powered tugs.
Why is it called a tugboat?
These are primarily used to tug or pull vessels that cannot move by themselves like disabled ships, oil platforms and barges or those that should not move like a big or loaded ship in a narrow canal or a crowded harbour. This came to be known as tug assist and thus the name of the boats.
Can a barge across the ocean?
Barges are designed to be used on shallow inland waters. They are not considered sea-worthy watercraft due to their flat bottom hull and shallow draft. However, there are commercial ocean-going barges that are used along coastal routes. A barge can be taken to the sea but it is not advised.

What is the most powerful tug in the world?
FUN FACT: While the 309.6t bollard pull of the ALP Striker is surely impressive, the Guinness World Record for the world’s most powerful tugboat is held by Farstad Shipping’s Far Samson, which achieved an astounding 423 tonne bollard pull during testing.
Why do tug boats shoot water?
Why Do Boats Spit Out Water? Boats typically spit out water to keep the bilge free of water. Water builds up over time inside the bilge and the bilge pump automatically pumps the water out again. Often, when boats are spitting out water, it is because they are expelling water that has built up in the bilge of the ship.
