This leads to several questions, including what exactly is the purpose, and how big is the anchor of a cruise ship? If these are your questions, you’ve come to the right place to find answers. The weight of the chain helps to keep the cruise ship in place. The anchor serves only as a point of contact with the seafloor despite its weight. The chain of the anchor is much heavier and is essential to keeping the ship motionless. Cruise ship anchors typically weigh between ten and twenty US tons.
What is the number of anchors on a cruise ship?
The first known use of ship anchors dates back to Ancient Greece, around 592 BC. This blog helps over a million people to plan their cruises each month. She has worked in the cruise industry since 2015 and has taken over 30 cruises. Now, she helps over 1 million people per month to plan their perfect cruise holidays. The anchor is hauled up and when it breaks the water the term ‘anchor sighted’ will be relayed to the bridge.
The Anatomy of a Cruise Ship Anchor Chain
Final tender times are published in the daily newsletter, and are also on signs as you’re leaving the cruise ship. When all available anchorages are occupied—a common occurrence currently—the MX/VTS must find “parking” for them. Crown & Anchor is the name of Royal Caribbean’s loyalty program for its cruise guests. With each cruise taken, passengers earn points with the program.

Cruise ships typically take precautions to prevent this from happening, such as using a warning siren when the anchor is being dropped. Modern anchors are made of a variety of materials, including steel, iron, and aluminum. They are also available in a variety of sizes and shapes to suit the needs of different types of ships. The earliest known anchors were made of stone and were used by the Egyptians as early as 2000 BC. These anchors were simply large stones that were dropped overboard to slow down a ship and prevent it from drifting away. Cruise ships usually have multiple anchors, typically ranging from two to four, to provide redundancy and ensure greater stability.

In dry docks, the entire chain can be removed and then reversed and put back in. Great Britain – the world’s first ocean liner which sailed from 1845 until 1886. But in reality, the anchors are alternated so that they wear equally. The way it works is for every 90ft extra links, and either side of the red shackle will be painted white.
The Importance of Anchors
The captain must choose whether to drop anchor or employ the dynamic positioning system if there are no regulations on anchors. 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. Large cruise ships utilize 3/8-inch thick chains, whereas smaller ships use 1/4-inch thick chains and medium-sized ships use 5/18-inch thick chains. With the use of thrusters and engines, modern ships maintain their position thanks to sophisticated positioning systems.
The flukes were designed to dig into the bottom of the sea and hold the ship in place. Cruise ship anchors are typically constructed from high-strength steel to withstand the immense forces and ensure safety while at sea. They undergo rigorous testing and maintenance to ensure their effectiveness. Cruise ship anchors function by deploying heavy metal chains and hooks into the water to grip the seabed securely. The crew then operates the windlass machine to lower the anchor, allowing it to dig into the seabed.

To give you an idea of scale Island Princess is a mid-sized cruise ship, 91,627 gross tonnes with a capacity for 2200+ passengers and 900 crew. As a ship moves away from the anchor, the anchor chain gently extends as some chain is lifted from the seabed, absorbing some of the force that’s moving the ship. At medium weight, the ship will have moved away from the anchor, and some of the chain will have been lifted from the seabed. To indicate the length of the anchor chain released are markings on the actual chain, individual chain links of a different color, usually a red shackle, and white links on either side. In the photo below, you can see a human and cruise ship anchor comparison.
However, if you have mobility challenges, you might not be able to board the tender. On most major cruise lines, you’ll need to get one tender ticket for your group or each member of your party for each tender port. When you’re planning a cruise, you might notice that some port descriptions will say, “this is a tender port.” Or you might see that tender boats or “tenders” are mentioned. Cruise lines usually specify which ports of call on each itinerary will be tender ports, and passengers have the opportunity to obtain tender tickets if they wish to go ashore.
Due to the weight and size of cruise ship anchors, it is difficult to use them for another purpose. 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. 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. Anchors are required for holding a ship in place and preventing it from drifting due to winds and currents. Modern cruise ships have what’s known as a stockless or patent anchor.
Tickets often will be available the afternoon before you’ll be tendering, as well as the morning of. In the most common usage with today’s cruise lingo, “tender port” is used as an adjective to describe a port that cruisers need to access via a small boat. Cruise ship anchors can cost anywhere from a few thousand dollars to several hundred thousand dollars. The anchor is lowered from the bow of the ship using a winch.
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. The long lengths of time that the ships would be at sea meant that anchoring was a necessity. When it comes to large ships, it isn’t just the anchor that holds the ship in place. The anchor is on the end of a long and heavy chain and the weight of this chain on the seabed helps to hold the ship in place. Staterooms located near the ship’s bow are some of the worst on a cruise ship.
