There is no question that timely repairs and preventative maintenance can extend the life of almost any workboat. It is also true that changing market conditions can lead to renovations to effectively extend the life of many vessels. The one event that triggers many repair projects is the Coast Guard's five-year hull inspection program, often referred to as a "shave and a haircut". Most operators use these occasions to inspect shafts, wheels and do top side repairs as well. With the hull is out of the water, not only can shafts, rudders and wheels be repaired, but also anodes replaced, sea chests inspected and the entire bottom given a coat of anti-fouling paint.
