Just like you want certified technicians to work on your car, boaters are the same way with their boats. That usually means training at one of the too-few marine trade schools with the appropriate area of expertise certifications. Also like automobile mechanics, many boat repair mechanics need an additional level of certification beyond various repair areas – special certifications from the manufacturer are highly prized, especially when the marina has a boat sales operation that specializes in that particular line of boats. The more such technicians meet these tests, the better the staff.
