What is the use of tugboats and how does it work?

When you have experience riding on a water ferry you will know that boats need to be anchored to the bollards that sometimes can sway sideways. Bigger ships that are stable on the open seas cannot navigate on the shallow waters or narrow ways. It is because the movement of the water in the narrow area has less room for the course. It can cause the ship to crash and it can have expensive damage. Even though it is a small boat yet it is powerful that can help to guide the bigger vessels which you will know as tugboats and they have an important function. It’s not a surprise to know that Pollisum have been considered one of the best tugboats companies in Singapore for the year.

Direct towing

With a direct towing it needs a powerful motor in the tugboat that is known as a winch. It is a motor that connects to the towing line that is used by vessels so it is easier to pull. When the connection is stable they will tug it and leads the way by pulling the vessels behind.

Indirect towing

The indirect towing of the tugboats is pushing the bigger vessels on their hull and rotating them around in a vertical axis and changing their course. It can be used later on when they have to use a direct towing. But when the vessels know how to maneuver and propel themselves they don't need towing assistance.


The indirect towing includes the pushing for course correction and there are certain vessels that need to be pushed all the way, it is their means of propulsion. When they have to push tugs they sometimes need to have reinforced hulls and bumpers that can fit the stern of the vessel that is being pushed. Also with the help of buoyancy, the tugboats don't need enough effort to move the bigger shops. But they have a strong structure that is being powered by a propulsion system that fits in the bow or stern of the ship.

Types of tugboats

Inland Tugs

It refers to tugs that can work in shallow waters and these can be classified by the following:

 Harbor tugs

Harbor tugs are reliable for the docking of bigger ships in and out of the harbors, narrow water, and ports. These will help by pulling the vessels by using a steel or fiber hawser.

 River tugs

From its name, these tugs can tow or push the vessels in and out of the seas. Since it is somehow powerful and can push many boats, the hull is made to be dangerous in ocean settings.

Oceangoing tugs

It is made deep-sea and these can be classified as follows:

Conventional tugs

Other than ocean tugboats it can push or pull the different types of vessels. They can do this by pushing or towing bigger vessels. And there are other crafts that it can attach to the sides of the vessels. Since it is versatile the conventional tugs are made to salvage operations. You can upgrade a few modifications to their hull and bow and they can now be used during the operations.

Barge tugs

Since the nature of the payload on boats is easier to push than towing them. Barges have a notch in their body that can manage a boat. These are attached or independent of the barge which means it is connected.
