Each link in the chain will look like an elongated oval, or it can be designed to have more of a “D” shape. These two shapes allow the chains to be connected in a way that maintains their strength but can still move smoothly. The below table shows the correlation between anchor weight and chain length. When a ship uses both anchors at the same time and they are both anchored ahead, this is known as an open moor. Nautical engineers use various methods to calculate the chain length. Good holding ground would suggest that the anchor will sit on the bottom there and will hold successfully.
How Do Anchors on Cruise Ships Operate?
Cruise ship anchors are also much smaller than anchors on traditional ships, and they are typically deployed from a crane on the ship’s bow. This is because cruise ships do not need to anchor in deep water, and they can use their engines to maintain their position in shallow water. 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.
How Heavy Are the Anchors on Cruise Ships?
Today, we will take an in-depth look at cruise ship anchor chains. While it may seem like a relatively simple piece of equipment, a cruise ship’s anchor is a marvel of modern engineering. 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.
Anchor Chain

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. Heave a heavy chunk of metal overboard to weigh down a ship so it doesn't drift away. Of course in practice, the process is a lot more nuanced, and it only gets more complicated the larger the ship is.
They will often feature large windows and outward-facing chairs where guests can comfortably take in the view and enjoy a cocktail. Some cruise lines require that guests be able to step on and off of tender boats with only minimal assistance. Most tenders have at least a couple of steps you’ll need to use to get on and off of the boat.

These are used to navigate tight spaces, like ports and channels, with efficiency and accuracy. This is because this part of the ship provides the navigational crew with an unobstructed view of the horizon and the ship’s surroundings. The bridge is the maritime term for a ship’s navigational center, where you will find the captain and other high-ranking navigation officers. It houses the ship’s primary navigation and communications equipment and the control systems used to guide the ship.

Hi Rick, when you're boarding a tender, there's always a crew member or two there offering a hand to help steady you as you're transitioning from the gangway to the smaller boat.

Even when a cruise ship is anchored in a harbor, the anchor chain must be capable of adjusting to fluctuations in water conditions. The tide can change the depth of the water rapidly, so if the chain is not flexible, it would be under much more tension. As mentioned, the anchor weight, chain length, and size of a cruise ship’s chain can vary depending on the weight and dimensions of the cruise ship itself. The most prominent component of a cruise ship anchor chain is the series of interconnected links that make up the bulk of the chain. These links are massive in scale, and they need to be constructed of high-tensile, high-strength steel. In the majority of cases, when a cruise ship is scrapped the anchor is scrapped along with the ship.

Two maintenance workers underneath the anchor of Norwegian Cruise Line’s ship Norwegian Jewel, which was raised for maintenance. Now that you know more about the bow and its important functions, take some time out of your next cruise vacation to visit this area. Take in the breathtaking views and marvel at the incredible amount of engineering that went into designing this unique part of the ship. Today, the bow also plays a vital role in scenic cruising, as it offers some of the best views of the entire ship.
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. Cruise ship anchor chains need to be made from high-strength steel.
In fact, it is often seen as the operational heart of the whole ship, which explains why it is where you will find the ship’s main navigational equipment and control center. After all the scheduled tender groups are called, the tendering process will change to “Open Tender“. From this time on, passengers without a tender ticket will be allowed to get off the ship. Plan to return with plenty of time to avoid missing the last tender.
In general, to get on and off of most cruise ship tender boats, you'll have a short step or two up, then a few steps down. The steps going down into the tender (and back out again) are generally a bit steeper. When you choose a cruise itinerary with tender ports, there’s a higher risk that your stop will be canceled or changed to another location. Tender boats don’t have age or weight restrictions for cruise passengers.
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. 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. Cruise ship anchors work by extending down to the seabed of shallow water and using their weight to hold the ship in position. Despite advances in technology, cruise ship anchors remain essential in ship construction.
If (like in the scenario you asked about) your ship drops anchor but no tenders go out, guests will still be refunded for those fees. But usually, the captain would make the call for weather-related reasons well before approaching the port to drop anchor. Yes, at tender ports (just like docked ports) port taxes and fees are assessed. You'll have pre-paid these fees by the time final payment is due for your sailing. If any port stop is canceled, the cruise line will refund you the taxes and fees for that specific stop.
For most cruise ships, the bow is also where you can find a landing space for helicopters, known as the helideck. While this is only really used for emergencies, like medical evacuations, it is still an essential feature of the bow. Below the areas where passenger and crew members can explore, the sharply angled bow shape is designed to glide through the water with minimal resistance. A conventional bow helps cut through the water so the entire ship can move faster and more efficiently, even in rough seas.
