The harbour lies within a mile of open sea and provides a sheltered haven almost half a mile long. There are no tidal restrictions to any of the berths in Montrose which offers around 1000 metres of riverside quay. The North Sea Oil and Gas industry which is now well established is an important trade in the port. This is fully under control of the Port Authority and consists of "One Stop" berths for offshore support vessels with open storage, office accommodation and over 10,000sq. metres of warehousing immediately adjacent to the berths.
