    In its simplest meaning, an anchorage is a suitable area in which to anchor a ship. The right to anchor a vessel is part of the common law right of navigation, which allows vessels to anchor temporarily and for a reasonable period of time in any appropriate location, unless specifically prohibited by statute or regulation. Some ships may only be anchored for a few hours but others will stay for weeks while they wait to collect or offload their cargo.

    Do ships have the right to seek anchorage?
    The right to anchorage is subject to local regulations but falls under the United Nations Convention on the Law of the Sea (UNCLOS) which provides for free navigation. In Canada, port authorities are responsible for the management of anchorages within the jurisdiction of their port. Any anchorages outside of a port’s authority fall under the jurisdiction of Transport Canada (TC).
    In the case of the Vancouver Fraser Port Authority (VFPA) they manage 28 long term anchorages located in English Bay, the Inner Harbour and Indian Arm. There are also an additional 33 anchorages available in the Salish Sea, which are administered by - and the responsibility of - Transport Canada. Under the Interim Protocol for the use of Southern B.C. Anchorages, TC has asked the VFPA to assist by assigning ships to anchorages around the Gulf Islands.

    The port does this by using an algorithm to assign anchorages equitably. According to a description published on the port’s website, considerations include: “[The]…size of vessel, anchorage use in Vancouver, the number of days an anchorage has been vacant, when it was last used, and the average number of days it was occupied. Wherever possible, we avoid assigning ships to Gulf Island anchorages.”
    The use of anchorages is on the rise on the British Columbia coast due to the growth in bulk traffic. According to TC, Vancouver has seen a 4 per cent increase in anchorage use every year since 2011.
    What’s the harm of ships sitting there? What are the environmental effects of anchorages?
    Ships at anchor have the potential to cause a variety of negative effects on the marine environment. This includes generating underwater noise that disturbs marine mammals (even when the ship is not in transit), importing invasive species, damaging the seafloor through the action of their anchor, dumping of waste and effluent, and air pollution from engine exhaust. And there’s the threat of spilled fuel oil should a ship run aground.
    Complaints collected by the VFPA include the general visual impact, noise from the generators, light pollution, anchor washing and ballast practices, and complaints relating to general safety and the age of the ships.
    In Canada’s North, residents of Nunavut want to see stricter guidelines around anchorages for pleasure craft, non-local vessels and larger ships. Some note that the extended presence of larger ships is affecting the migration patterns of animals driving some away for up to a month. As with many contentious public policy issues, it is not always a simple issue and can be quite nuanced. Some residents want to see port development so that there will be safely designated boundaries and anchorages with enforceable regulations; others want to see improved communication between vessels and the communities around anchorages.
    For Indigenous communities, anchorages affect their way of life and ability to harvest food. The Cowichan Tribes, who live along the Gulf Islands in the Salish Sea, have expressed opposition to anchorages based on the need to protect clam beds, prawns, oysters and endangered species such as Southern Resident killer whales. They are especially concerned about anchor dragging and scouring.
    Ship anchors can weigh up to 30 tonnes and are designed to hold vessels in place. The anchor chain can be hundreds of metres long, and the excess chain lies on the seafloor to stabilize the vessel in waves, wind, and currents. When the vessel swings around due to changes in wind or tides, the anchor chain can drag across the seabed and cause damage to the seafloor as well as to flora and fauna. In areas where multiple ships frequently anchor, the environmental damage can add up and research into the lasting effects is ongoing.
