I wanted the day to end before we even made it to the Vatican on our tour. As someone who's taken over 50 cruises all over the world, I know firsthand how popular cruising is this year. But one seabound itinerary people often forget to add to their bucket lists is a Mediterranean cruise. A U.S. Coast Guard patrol board encountered seven Chinese and Russian naval vessels cooperating in an exercise last year about 86 miles (138 kilometers) north of Alaska’s Kiska Island. Currently three ships can dock at once; the expanded dock will accommodate seven to 10. The expansion will be completed in three phases and effectively double its size.
How Much Do Cruise Ship Anchor Chains Weigh?
That was the case for the Canada Place cruise ship terminal on Sunday, which saw all three of its berths fully occupied by three large ships — the Noordam, the Serenade of the Seas, and the Celebrity Eclipse. The Viking Orion was the fourth cruise ship to call in Vancouver that day. FYI, a useful site is whatsinport.com that identifies information about the port of call and links to the cruise schedule calendar where you can find out what ships are due in port on your day.
Do Cruise Ships Have Multiple Anchors?
This cruise ship season in Vancouver, the first in two years, is slated to be an exceptionally busy one. Over 300 cruise ship calls are expected between April and early November of this year — up by 8% compared to 2019’s record year for Canada Place’s cruise ship volumes. At least one cruise ship is scheduled to call at Canada Place almost daily between early May and early October. In the blue book, either "dock" or "anchor" was listed for each port. However, I am a cynical sort so I often double check the actual ports' schedules if I want to know for sure (and even then it might change).
Cruise Ship Anchors
However, the cruise ship often only utilizes one anchor, saving the other for emergency usage. Living on a cruise ship grants you the opportunity to explore a multitude of exotic destinations. With various itineraries, you can sail to different ports and immerse yourself in diverse cultures and landscapes.
Associated Data
The chain, which rests on the seafloor, needs to have enough slack when an anchor is lowered into the water. More surface area of contact with the seafloor is made possible by the slack, which absorbs more movement. In contrast to short chains, which may allow the anchor to lose contact with the seafloor in choppy conditions, longer chains can tolerate greater movement. To determine the chain length, nautical engineers use a variety of techniques. The cost to live on a cruise by Life at Sea cruises starts at $29,999 per year. There are payment options available, with the lowest starting at $2,499 per month.
CRUISE HIVE NEWSLETTER
This is relevant to many of the Caribbean SIDS which have coral-rich habitats, are highly vulnerable to environmental challenges and depend heavily on their natural marine resources for industries such as tourism and fisheries. Examples of IMO-designated PSSAs in the Caribbean include Saba Bank, Sabana-Camagüey Archipelago in Cuba and the Florida Keys. If a no-anchoring policy is implemented, cruise ships unable to enter the port or use the Quarantine Anchorage could use their Dynamic Positioning System (DPS) to maintain their position without dropping anchor. The Government of Barbados welcomed cruise ships during the early COVID-19 period of 2020, allowing them to seek safe harbour at a time when many countries were turning them away. A total of 28 cruise ships were given unprecedented permission to anchor along the west and south coasts of the island during this period (1 March – 1 September 2020). This study examines the 132 anchoring events of these cruise ships, using automatic identification system (AIS) data to determine anchored locations and track vessel swing at anchor in relation to sensitive coral-rich habitat.
As a result, the ships were told to move and on more than one occasion the coastguard was deployed to assist, resulting in the ships re-anchoring in virtually the same location7. The 100s of metres of anchor chain required to anchor such large vessels and the swing of cruise ships whilst anchored was likely unknown or perhaps overlooked when choosing these alternative anchorages. As such, another solution is needed for when marine traffic is heavy. The most effective way to prevent further damage in the future would be to prohibit cruise ships from anchoring outside of the designated Quarantine Anchorage.

Cruise ship anchors dig into the seabed and provide a contact point for the ship. Having to take a tender boat to land is a very common part of cruising. Guests are usually able to see ahead of time if the ports that they are visiting will require tendering. While this method is more straightforward and versatile for ships, it also uses up more fuel and comes at a high cost. They are typically 10 to 20 feet long, 15 to 20 feet wide, and weigh anywhere from 10 to 20 tons.
Furthermore, the Government of Barbados has now embarked on a ‘Roofs to Reefs’ programme to further integrate the management of land-based and marine activities (Ministry of the Environment and National Beautification, 2019). The reef resembled a marl road with large rock boulders strewn about and little to no architectural complexity (Fig. 6). The site is essentially now devoid of living coral and other common reef biota such as sponges and gorgonians and demonstrates the extent of damage that can be caused by continued anchoring of large commercial vessels. Thirdly, individual cruise ships have a responsibility to ensure that their anchoring is not likely to damage reef habitat.
It was 2016, and at the time, the cruise ship Serenity was the largest vessel ever to sail through the Northwest Passage. Cruise ships anchoring in Barbados were monitored over a period of 27 weeks from 1 March to September 1, 2020 (Fig. 1). The highest number of anchor drops (9–16 per week) happened in weeks three to seven (15 March – 18 April), remained fairly stable through May–June and then declined through July–August with the last anchor being hauled on 16 August (Fig. 2).

As you can see, the size is similar, although the shape of cruise ship anchors has changed quite a lot over the past 170 years. In the majority of cases, when a cruise ship is scrapped the anchor is scrapped along with the ship. There are a few examples though where cruise ship anchors have found new lives after their ship was scrapped. Due to the 2020 cruise industry shut down a number of cruise ships had to anchor out to sea for long periods of time.
So hearing that cruise ships still use what may be considered ancient technology – such as anchors – may come as a surprise. Early morning is when cruise ships typically dock at places of call. Furthermore, nobody wants to wake up at five in the morning to the sound of a freight train as the ship drops anchor. As a result, the second will serve as a backup in case the first breaks down for any reason. Usually lighter than the other two anchors, the third anchor is smaller. Its main purpose is to serve as a backup in case the main anchor fails or malfunctions.
A video was recorded of the entire length of deployed anchor chain so the number of links could be counted, and the length of chain estimated. The GPS location of the dive boat at the start of dive (directly below the anchor hawsehole) and at the end of the dive (directly over the anchor) were also used to validate the length of the anchor chain deployed. As passengers tender into the port of call, Princess Cruises’ cruise ship is anchored in the Caribbean.Anchors are used by cruise ships to keep them stationary. In tender ports, where the ship is unable to moor to a land-based dock, cruise ship anchors are frequently utilized. In situations where ships must stay in deep water and an anchor might not be long enough, dynamic positioning devices are frequently utilized.
3c and d many cruise ship anchors were likely dropped on or near coral reef such that the anchor itself and/or the anchor chain would have come into contact with the benthic coral reef community. Almost half of the cruise ships (11) anchored on hard coral framework reef. Additionally, many of the anchored cruise ship positions are close to popular SCUBA diving sites used by the island's dive shops given that dive sites are mainly found on hard coral framework reefs (Fig. 3c and d). All five cruise ships that anchored on the west coast (Cruise ship Nos. 11, 23, 24, 25 and 28) anchored in close proximity to the hard coral framework (i.e. the bank reef). Three ships on the west coast anchored close to or directly on three popular SCUBA diving sites. On the south coast, the cruise ships mainly anchored on hard coral framework reefs and hard coral patch reefs.
The third anchor is often smaller and weighs less than the primary two anchors. It’s primarily used as a backup if one of the primary anchors breaks or malfunctions. Most modern cruise ships have two anchors, with one on the port side and the other on the ship’s starboard side. While the exact frequency of inspections will depend on the particular policies of each cruise line, most anchor chains are inspected as part of the cruise ship’s regular inspection and maintenance procedures. If the draft of a cruise ship is too deep for a shallow port and waters, this prevents the cruise ship from docking. The cruise ship will have to anchor offshore in deeper waters, and passengers will have to be tendered to port.
If no fixed mooring points are available, some cruise lines will opt to use dynamic positioning systems to keep the ship idle using the ship’s engines. The bridge simply inputs the coordinates, and the system takes care of the rest. In other words, the cruise ship could still get from point A to point B, but it won’t manage to stay idle without anchors or dynamic positioning systems.
