Anchoring is an essential part of any cruise ship’s journey – allowing them to safely remain in place while at port or other destinations. It involves locating a suitable area with enough depth of water before deploying an anchor connected by heavy chains onto both sides of its bow. In some cases additional anchors may need to be deployed depending on wind strength and direction, ensuring that passengers can enjoy their voyage safely and securely. Dynamic positioning systems are commonly used when ships must remain in deep water, where an anchor may not be long enough. While the chain length limits the use of anchors, the dynamic positioning systems don’t have any limitations.
How Long Are Cruise Ship Anchor Chains?
Unlike other vessels, cruise ships have the ability to anchor themselves when they reach their destination. This process is called anchoring and it’s a critical part of any cruise ship’s journey. Utilizing the sea bed is why cruise ships can’t rely on anchors in deep or open water. These anchors’ chains have a limited length; if the anchor can’t reach the sea bed, it can’t perform its function.
Cruise Ship Anchors: What You Need to Know
Anchors are generally proportional to the size of the cruise ship. The larger and heavier the cruise ship, the larger the anchor can be expected to be. I hope that this article has answered your questions about cruise ship anchors.

During these inspections, each chain link is checked for signs of damage and corrosion. As you would expect, the frequency and closeness of inspections can increase if the crew suspects that the anchor chain could be damaged. As you may know, a seabed in one area can differ in composition from one area to the next.

I Spent 7 Days on My First Adults-Only Virgin Voyages Cruise
The tours are usually led by locals, which means the guides can also give you some good recommendations if you have time before you need to return to the ship. My biggest tip for any cruise — but especially for Americans traveling to Europe for a Mediterranean cruise — is to arrive at your embarkation city at least a day before your sailing starts. After taking my first Mediterranean cruise last year, here's what I think everyone should know before booking the route.
While they don’t impact coral reefs like the anchor, burning fuel has its own environmental impact. 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. Most cruise ship anchor chains also feature depth markings at evenly spaced-out intervals. 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.
Many modern cruise ships would be able to use dynamic positioning if all anchors were lost for some reason. 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. However, some modern cruise ships primarily use dynamic positions, which means they use propulsion and thrusters to maintain a steady position. 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. Local rules in several cruise ports forbid using anchors to save coral reefs.
Dynamic positioning was created in the 1960s for offshore drilling but it is a relatively new piece of cruise ship technology. When a ship uses both anchors at the same time and they are both anchored ahead, this is known as an open moor. It is common for ships to have two anchors, one on the port side and one on the starboard side of the ship. I recently saw a replica of the Titanic’s anchor which made me wonder if modern ships still have anchors. Considering that they’re meant to spend large amounts of time in the water, they use metals resistant to long-term corrosion damage. They may also be made from fiber-reinforced composites or polymers such as carbon fiber.
Dragging can be caused by a number of things like wind or current. On a chart on a ship, it indicates the nature of the bottom – whether it’s what’s known as ‘good holding ground’ or ‘poor holding ground’. Watching a ship come to anchor early in the morning can be quite the spectacle. If you’re lucky enough to see it, you may notice the wash from the propellers come alongside the vessel as it comes astern. Once the wash reaches the middle of the ship, it’s a sign that the ship has stopped moving through the water. Sometimes, if you’re cruising into a place and you’re going to be turning into a current slightly, it’s more prudent to put down the anchor which is on the current side of the vessel.
When vessels anchor, it results in anchor scour as the anchor is dragged to set it and the chain drags back and forth over the substratum as the vessel moves with the wind and changing tides (Davis et al., 2016; Broad et al. 2020). Cruise ships in particular, can cause significant damage to coral reefs because of the size of the vessels and weight of the chain and anchors needed to hold them. Burke and Maidens (2004) noted that reckless anchoring can cause up to 200 m2 of damage to the ocean bottom, even when the sea is calm. Other reports record even greater damage (e.g. Smith, 1988; Rogers et al., 1991). Additionally, they reported that only 60 percent of the species richness of low anchoring frequency sites was found on the high anchoring frequency sites. Anchor and chain scour damage to reefs was reported by Broad et al. (2020) to result in slow coral recovery and increased algal cover, whereas Forrester et al. (2015) reported an absence of recovery.
The local reef fishery contributes to food security on the island and is important in supporting livelihoods particularly during the pelagic fishing off-season (Schuhmann et al., 2011; Peterson et al., 2014; Gill et al., 2019). Despite advances in technology, cruise ship anchors remain essential in ship construction. Today’s massive cruise ships are some of the most technologically advanced vehicles on the planet. To learn more about the anchor of a cruise ship, rather than just the chain that connects it to the ship, we recommend reading about how big a cruise ship anchor is. This straightforward guide explains how big these enormous anchors need to be and provides other helpful information on how modern anchors work.
Plata (2019) reiterates that the benefit that Barbados derives from coral reefs largely depends on the health of those coral reefs. Further, the Coastal Zone Management Act (1998)5puts a price of US$ 150 on every square metre of coral reef damaged. This involved purchasing archived data from 1–31 March, as well as accessing open-source, real-time data from the MarineTraffic website and through their dedicated mobile phone application between 1 April and 1 September. Cruise ships generally avoid using the anchor due to the environmental impact on coral reefs and the seabed. Smaller vessels use 1/4 inch thick chains, medium ships use 5/18 inch chains, and the biggest cruise ships use 3/8 inch chains. Ship stabilizing thrusters consume fuel and are liable to malfunction and damage.
The Bering Strait shipping lanes have gotten only busier since 2009, going from 262 transits that year to 509 in 2022. It wasn’t, but the interaction inspired Bioff to create her own line of waterproof jackets styled like kuspuks. She now sells to tourists and locals alike from her own Naataq Gear gift store, a retail spot in the post office building, where about 20 Alaska Native artists offer ivory carvings, beadwork or paintings through consignment. Bioff was a tour guide who greeted the Serenity's passengers when they arrived in 2016. One of the guests admired her cloth kuspuk, a traditional Alaska Native garment similar to a smock, and wanted to know if it was water resistant.
The cabin sizes range from 130 square feet to 260 square feet with varying views. While there are challenges to consider, such as limited space, lack of privacy, and constant movement, with the right mindset and preparation, you can navigate these obstacles and make the most of your experience. The maintenance-free living provided by the ship’s staff ensures that your needs are taken care of, allowing you to focus on enjoying retirement and leisure. For our August/Sept cruise last month, the narrative 'dock' and 'anchor' were posted beside each port of call on page 1 in the Your Voyage (General Travel and Onboard Information) booklet in the Cruise Vacation Guide.
