A powerful, fast motorboat can tow a person flying over water with a paraglider, paraglider or delta kite. The start can take place from a meadow on the bank with the line initially laid out zigzag, here the person has to run a few steps, possibly even pull up an umbrella before he takes off.

In shipping, the towed and towed watercraft are referred to as towing units or tow trains. It can comprise several vessels. The towing vehicle can pull, push or take the others alongside. The way the lights are guided is different, depending on whether the towing unit should be recognizable as a unit that belongs together or whether it represents a train.
In maritime shipping , vehicles that are unable or disabled to maneuver or vehicles without a motor (e.g. racing sailboats of certain classes) are towed when they are pulled by a motorboat.
Tugs are used to pull disabled boats into a port or to bring very large ships safely to their intended berth in a port. In principle, each boat may tow a different one if necessary or desired. Towing under sail is challenging, but also possible.
In the Panama Canal (old) ships are pulled by several locomotives on rails on the bank.

In contrast to towing, towing is pulling a roadworthy vehicle. This creates vehicle combinations. According to German traffic law, because of the number of axles (towing vehicle and "trailer"), a class C driving license is required when towing.
railroad
The term is not used on the railroad . In the case of industrial railways or trams, on the other hand, a rail vehicle can also be towed by a road vehicle.
Cable winches are used in industrial companies and maintenance systems to tow vehicles. The terms siding and siding for siding and industrial main track come from this.
There is also the option of crossing parallel tracks in a cross circle on which a rail vehicle engages just enough that its winch is centered on a track to be operated. This has been implemented on the west side of Graz Central Station, in order to pull electric locomotives from a repair shed with several tracks to under the overhead line.
