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. While casual cruise-goers often overlook them, there is an incredible amount of engineering that goes into making and maintaining a cruise ship anchor chain. Not only is the scale of the individual links impressive, but the ability of the chain to withstand immense forces is also truly a marvel of maritime engineering. In some cases, the waters the cruise ship traverses can also be a factor when determining how large the anchor chain needs to be. For example, large ships that traverse deep waters with strong currents need a much larger anchor and anchor chain than small boats on shallow water that stay close to the coastline.
The Chain Links
These allow crew members to easily determine how much of the chain has been released by the anchor windlass. Typically, these markings are made with bright, scratch-resistant paint; however, they can be made by stamping impressions into the metal. The most prominent component of a cruise ship anchor chain is the series of interconnected links that make up the bulk of the chain.

Do Cruise Ships Have Anchors? (The Answer May Surprise You!)
On the other hand, anchors are much more economical when keeping the ship in place since they consume no fuel. "The chain was draped across that whole entire span of the reef, so the area that it covered was absolutely massive," Prodahl told Cayman News 27. "It was constantly moving back and forth across the reef and causing a lot of damage as it did that." The reef and its surrounding sea-grass beds provide a nursery for juvenile fish and other animals.
Anchors getting stuck
The ship’s thrusters can keep it stable even if it loses all of its moorings for whatever reason. Additionally, they lessen the possibility of an anchor disturbing coral reefs. Read about an anchor lost after getting stuck near San Juan for an example of how and why large vessels could be forced to cut its anchor loose.
How Many Anchors Do Cruise Ships Have?
At one end is the anchor itself, which is connected by a stout chain. So that the chain can be stowed on board in a capacious chain locker below decks. It is a simple system yet with critical importance for the safety of the vessel. Each link in the chain is made from high-grade steel with incredible tensile strength. While the chain size will vary depending on the size and weight of the cruise ship, they are all incredibly large and heavy.
We’ll also discuss some of the different types of anchors that are used on cruise ships. The cruise ship will be at the mercy of the moving sea as long as it is not sailing, in the unlikely event that both the anchors and the dynamic positioning systems sustain damage. Cruise ship anchor chains need to be made from high-strength steel.

Most vessels have an anchor on both the port and starboard sides. One area that was affected by this was the south coast of England. There are no laws that say that cruise ships cannot drop anchor when out to sea and as a result this is how most ships spent the year. If a ship is unable to dock in a port due to shallow water it may be necessary for the ship to hold a position out to sea and to transport its passengers using tender boats.
Many modern cruise ships have ‘dynamic positioning’ meaning that they use propulsion and thrusters instead of anchors to maintain a steady position. Dynamic positioning technology has reduced the need for traditional anchors but has not eliminated their use completely. Cruise ship anchors are usually between feet in length and weigh between 10 and 20 US tons. Safe anchorages are defined on nautical charts and are usually designated by numbers and/or letters.
Are Anchors Still Used on Cruise Ships?
Anchors also help to slow down ships and stop them from drifting away. Cruise ships can only anchor in seas where the anchor can comfortably reach the bottom of the sea bed and still have enough chains left to lay on the seabed. There are usually two anchors on a cruise ship, one on the port side and one on the starboard side. As a last resort, the anchor chains would have to be cut, leaving the anchor on the seabed. Rather than lose the anchor, a buoy could be attached to the last piece of the chain so it could be recovered later. The longer the chain, the more force it can take before breaking the anchor free of the seabed.
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. Most modern cruise ships have two anchors, with one on the port side and the other on the ship’s starboard side.
A cruise ship anchor is a device that keeps a vessel in place. The anchor is lowered from the vessel using a heavy anchor chain and digs into the seabed to ensure the ship stays stationary in the water. In the improbable scenario that both the anchors and dynamic positioning systems also get damaged, the cruise ship will be at the mercy of the moving water as long as it’s not sailing. In conclusion, the weight of a cruise ship anchor is a crucial consideration in maintaining the safety and stability of these remarkable vessels. By understanding the various factors and methods involved, we gain a deeper appreciation for the meticulous planning and engineering that goes into every aspect of cruise ship operations. When all these components come together, they form a robust and reliable anchor capable of securing a massive cruise ship in various port conditions.
This is because they are primarily designed for anchoring in shallower coastal waters. Excess anchor rode is not on board because it takes up too much space and is rarely required. The weight of anchor chains plays an important role in holding a cruise ship in position, much more so than the weight of the anchor itself. The average weight of cruise ship anchors ranges between 10–20 US tons. The weight can go considerably higher to accommodate the largest ships.
Remembering the chains that secure these anchors is important. The thickness of the chains and the anchor they are intended to hold determine their length and thickness, respectively. However, because they don’t use any fuel, anchors are far more cost-effective for keeping the ship stationary. These surface treatments can not only delay corrosion, they can also help prevent scratching as the chain links rub against each other and even the hull. The individual links within the chain are joined together using a detachable mechanism. Basically, this mechanism consists of a connector and an anchor shackle.
Its main purpose is to serve as a backup in case the main anchor fails or malfunctions. Chris Allen’s replica of the Titanic’s anchor, available on Wikimedia Commons under CC BY-SA 2.0The normal size of a cruise ship anchor is 8 to 15 feet wide, with a length of 10 to 20 feet. The size of an anchor is closely correlated with the size of the vessel. Even with dynamic positioning systems’ benefits, anchors are still necessary in this modern world.
