What kind of work a Tug Master do?
Tug Masters operating in port can be called upon to help with ship berthing or unberthing, or to guide a vessel through dangerous or hard rivers. The port Tug Master, working closely with port officials, masters and pilots, will generally head out to meet the vessel at sea to attach a line before skillfully guide it to its berth.
In the US, pusher tugs can be used to push lengthy barges trains on rivers and inland waterways, while ocean-going tugs can be engaged in avoidance of pollution, rescue, fire-fighting and rescue. Tug Masters can also help vessels in trouble or the towing of oil rigs.
