Tug Masters control the strong ships used in ports and harbors to help ship motions. Tugboats are highly strong watercraft while small in size, and their handling requires a great deal of skill.
The Tug Master must also have thorough understanding of the waters in which he / she operates to prevent incidents. The nature of the job implies that Tug Masters can often expect to operate in shift patterns under all weather conditions, and the working hours can be long and irregular when Tug Masters are at work.
