Ankh Tattoos Explained: Meanings, Symbolism & Tattoo Designs

ankh tattoo design

Others say it was about the deep skin of the Black people who lived there. It is very much alive, and an important part of Kemetic spirituality. Something important to understand is that the ankh isn’t a dead symbol.

Ankh Tattoo with Eye of Horus

One form involves replacing individual letters in a word with the letter’s number in the alphabet – 1 for A, 2 for B, 3 for C, etc. As we’ve talked about the Eye of Ra and ankh, you should also know about the Eye of Horus. Just like the meaning of Eye of Ra and Ankh is related to Egyptian mythology, Gods and Goddesses, the Eye of Horus meaning is also related to the same. Get your own unique Egyptian tattoo by incorporating tattoos of Egyptian deities in ankh and Eye of Ra tattoos, as it’s shown in the picture. Anubis can be seen in the picture with both the ankh and the Eye of Ra. Ankh represents the key of life and in Ancient Egypt, was also known as the key of the Nile.

Otherwise called the “cross of life” by the antiquated Egyptians, it represented the association of people. Where he was conceived is the slight end, the round top of the Alexandria delta where he spilled, the arms that open to the right and left are the east and west sides of the Nile. The Ankh’s beauty lies not just in its look, but also in its significance. The ankh is an ancient Egyptian hieroglyphic symbol that represents the key of life, and is often seen as a symbol of immortality. It was also used in connection with the concept of fertility, which can be seen in its resemblance to the female reproductive organs.

Tribal Ankh tattoos typically feature bold lines and geometric shapes, while blackwork Ankh tattoos often focus on shading and contrast. No matter what style of tattoo you choose, it is important to make sure that it accurately reflects the meaning behind the design. The Ankh is often seen held by Egyptian gods and goddesses, especially by Isis.

Ankh Tattoos: Modern Take on an Ancient Symbol

Some see the Ankh as a reminder to embrace life and live it to the fullest, while others see it as a way of honoring lost loved ones or overcoming personal struggles. The Ankh can also be seen as a symbol of individuality, strength, and self-love. The Ankh symbol has also been adopted by modern-day cultures and has become a popular symbol in fashion, jewelry, and tattoos.

Moreover, the ankh promotes the idea of seeking balance not only within oneself but also in relation to one’s surroundings. It reminds individuals to be mindful of their interactions with others and the environment. By cultivating a sense of empathy, understanding, and respect for others’ perspectives and experiences, they can contribute to a harmonious coexistence. This Ankh tattoo design attracts the onlooker like honey attracts bees. The Ankh tattoo is a representation of the life cycle and all that life encompasses good and bad. This meaning is fantastic for anyone who wants to show that they understand that they will accept all that is thrown at them throughout their lives and, hopefully, keep their heads high.

Although simple in design aesthetic, and easy to stencil and experiment upon, the Ankh tattoo’s symbolisms are as diverse in nature as they are ancient. It would take a book of biblical proportions to just explain how many meanings and supernatural and mystical deities this tattoo represents. In Egyptian writing, the ankh was used to represent the word “afterlife”, so a piece of body art featuring Egyptian cross tattoos could represent this mythology. Sometimes it can get confusing to choose the right tattoo design, especially when there is so much variety. Mentioned below are some of the best ankh tattoo designs that will help make your selection process easier and much more fun.

Furthermore, the ankh serves as a reminder to strive for peace and serenity. In a world filled with chaos and conflict, it encourages individuals to seek tranquility both internally and externally. By finding ways to calm the mind, nurture positive emotions, and engage in actions that promote peace, individuals can create a more harmonious and serene atmosphere around them. Another unusual but exotic tattoo design is this last tattoo on the chest of a woman. To have an Ankh tattoo on the chest is more like an invitation for eyes to pry and interpret. The Ankh looks different as it has wings instead of the “T” and then there is the Eye of Horus beneath it.

How Do Cruise Ships Float With So Much Weight?

how do cruise ships stay afloat

In addition, the ship's crew is trained to adjust the ship's course and speed to minimize the effects of waves and motion. If you’ve played Jenga, you know that the second your tower gets top-heavy, it’s only a matter of time until it’s tumbling down. That’s because a low center of gravity is your best insurance. Cruise ships keep their heaviest equipment—fuel tanks, engines, machinery and freshwater tanks—in the lowest part of the ship for just that reason. The upper parts of the ship tend to be much more open, which also allows wind to pass through.

Displacement

To achieve this, engineers and designers must carefully consider the hull design, deck structure, and weight distribution. The buoyant force acting on a ship is affected by the shape and size of the ship. A ship with a larger surface area will displace more water and experience a greater buoyant force, making it easier to float.

Wonder of the Seas

Given those dimensions, it’s not surprising that cruise ships are often called “floating cities.” They are just that big and have so many people on board. A square shape maximises space on board as well as making the ship more stable. The T stands for Tropical, the S stands for Summer and the W stands for Winter.

Bilge keels are long, flat fins that extend from the sides of the ship below the waterline. These fins help to dampen the ship’s rolling motion and improve its stability. The combination of weight distribution, mechanical stabilizers, and bilge keels ensures that a cruise ship remains stable and safe, even in rough seas. It’s amazing to think about the sheer size and weight of these vessels, and yet they glide through the water with ease. It’s a question that has puzzled many, and the answer lies in their clever design.

How do cruise ships stay afloat with so much weight?

I know that this article was much more technical than others, but I wanted to make sure that the important question of, how does a cruise ship float was throughly answered. When a cruise ship arrives at a port, it must be safely secured to the dock. The ship's crew will throw lines to dockworkers on shore, who will then secure them to bollards on the dock. Cruise ships have multiple engines and thrusters to provide redundancy in case of an engine failure. This ensures that the ship can continue to operate even if one or more engines are out of commission. The center of gravity is a critical factor in maintaining stability.

Others break apart further and continue traveling through space. If a cruise ship is coming into a port with mixed water levels, a maritime pilot or harbor pilot, as otherwise known, will be sent out to guide the cruise ship through the deepest water levels to dock. Weight distribution is vital in ensuring the cruise ship has a low center of gravity. This is because of its density, the stone weighs more than an equal volume of water. Not to mention the weight of hundreds of crew members who live onboard the cruise ship. When it's time to set sail again, the ship's crew will use the winches to retract the ropes and pull the ship away from the dock.

The reason for this is that when you have more weight on top, it will push down harder than if there was less weight on top. This means that the center of mass moves to the bottom and thus the boat sinks. Negative buoyancy happens when the ship is partially submerged beneath the waves. The ship may not be entirely covered by water, but the area underneath the ship is filled with water. Because wood density is less than water, the stick or tree trunk will float.

For an overall explanation of all aspects that keep a cruise ship aflot, check out this video. It has some good visual examples to illustrate some of the key points I’ve highlighted above. You can see this more clearly when you look at the bottom of a cruise ship. This is because the apple’s weight is spread over a much larger volume in relation to its weight. When the weight of an object is more than the upthrust, it will sink. Her lifelong passion for travel has taken her to countless destinations around the globe, but cruising, undeniably, holds a special place in her heart.

Additional Features Supporting Buoyancy

Fundamentally it comes down to physics and creating a ship that is equal in weight to the water it displaces. It’s the action of an upward force on an immersed object (cruise ship) in fluid (the sea). The force is equal to the weight of the displaced fluid by the object. Have you ever wondered how cruise ships can float so effortlessly on the water despite their huge size and stature? Wonder of the Seas also features advanced technology that helps it to stay afloat. The ship's hull is designed to be streamlined, which reduces drag and helps the ship to move through the water more efficiently.

In addition, ships are equipped with sophisticated navigation and communication systems to help avoid accidents and respond quickly in the event of an emergency. To stabilize the ship, there are also ballast tanks below deck. These contain water that can be pumped from both ends of the ship as needed to maintain its overall stability.

But for practical reasons (this can vary as to the regions of the world and time of year) and on most cruise ships, the S load line is used. Passive tanks are tanks that are designed inside the vessel and they use ballast water to add and discharge weight as a means of counteracting the roll motion. If designed correctly, flow motions inside the tanks due to roll act as a damping force.

In order to reduce rolling at sea and improve the experience of passengers onboard, cruise ships are equipped with stabilizers. However, it is a more complex system and includes both passive and active stabilizers. A solid bar of steel dropped from a cruise ship balcony will undoubtedly sink until it reaches the bottom of the sea.

This is achieved by placing heavy items like engines and fuel tanks at the bottom of the ship and lighter items like cabins and restaurants at the top. Basically, objects at sea, be they huge cruise ships or chunks of driftwood, float because of the principle of buoyancy. The buoyancy of an object on the water depends on its density. Ships push on the ocean’s surface when they sail, but to float with Archimedes’ principle, they must displace quite a lot. Condensed items like balls and small weights sink because they do not push out much water. As long as there are no leaks, the displacement of water equals the ship’s weight.

This helps to increase the ship's buoyancy and makes it easier to maneuver through the water. In fact, these vessels are so well made that it is rare for guests to experience or feel side-to-side motion. Even more so, cruise ships never turn over despite being so huge and heavy.

Cruise the waves designed by Digital Burst Media

Whether you’re curious about how these massive ships stay afloat or any other aspect of their operations, our guide is here to help you out. However, steel alone is not enough to make a cruise ship float. The ship needs to be designed in a specific way to ensure that it is buoyant. The hull of the ship is designed in a U-shape, which helps to displace thousands of tons of water. This displacement pushes the water down and to the sides, creating a force that helps to keep the ship afloat. Overall, the science of stability is a crucial aspect of cruise ship design and operation.

Two Forces Meeting

Royal Caribbean's cruise ships are amazing pieces of technology, maritime tradition, and innovation, but they are not magic. Royal Caribbean operates the biggest cruise ships in the world, and a ship (if stood upright) that is twice as high as the Washington Monument might leave you wondering how it doesn't sink. Smaller cruise ships typically have a draft of less than 7m (22ft 9in) and so they can enter smaller ports. This is why, when you cruise on a smaller ship, with a cruise line like Azamara or Silversea, you’ll get to visit the smaller, less-touristy ports of call. Stabilizer systems are used to dampen these motions which can lead to travel discomfort problems like seasickness for passengers and crew onboard the vessel. All vessels are designed so they operate in certain sea states and the standards have a high safety margin in terms of adverse weather conditions the vessel may ply through during her operational life.

What is buoyancy?

Let's remember that it is also burdened with the weight of 3,500 passengers and all their luggage. When an object floats, it doesn’t always mean that it stays completely stable. Sometimes, objects fall over due to gravity pulling them into the earth. For example, if you drop a ball from the roof of a building, it falls straight down until it hits the ground. However, if you throw the same ball up high, it won’t hit the ceiling unless someone catches it before it does.

Managing Ship’s Weight

The force of releasing that water helps to balance the boat when it leans or sways. When water displaces, it tries to reclaim the areas it’s pushed out of, from outside and below. When the force of the liquid pushing back equals the force of gravity caused by the ship’s weight in water, a cruise liner stays perfectly afloat. If you want to know how much difference there is, just measure the distance from the center of mass to the surface of the water before adding any extra weight and after.

Wonder of the Seas

When the ship moves backward, the water flows back into its original position. In other words, the flow of water around the hull creates pressure pushing upward on the bottom of the boat. This causes the bow to rise up until the net forces acting on the vessel cancel each other out. To ensure the U-shaped hull design is effective, buoyancy calculations are critical. The weight of the ship, combined with the weight of passengers, cargo, and fuel, needs to be carefully considered to ensure the ship can stay afloat in the water.

The shape of the ship’s hull is also critical in ensuring that it stays afloat. A single cruise ship carries thousands of people, and some of them weigh over 200,000 GT (gross tonnage). Having such a hefty weight and size to hold enough people for a small town, how do luxury liners stay afloat?

The ship's engines and propellers are also designed to be highly efficient, which helps to reduce the amount of fuel that the ship needs to operate. They are equipped with stabilizers that reduce the rolling motion of the ship. These stabilizers work by creating resistance to the water, which helps to keep the ship steady.

Cruise Ships Are Designed for Stability and Smooth Sailing

The concept of buoyancy is what keeps a cruise ship like Symphony of the Seas upright and floating. Maritime Page is your go-to source for all things related to the maritime industry, from personal watercraft to the largest seagoing cargo ships and cruise vessels. Royal Caribbean International is a popular cruise line that has been operating since 1968.

For starters, this provides better protection against icebergs. Displacement and buoyancy aren’t the only factors keeping cruise ships floating. Cruise ships are equipped with a variety of safety features to prevent sinking.

Its motion is governed by sensors to counteract external forces. As an aside, the same watertight compartments also prevent the spread of fire – a maritime catastrophe feared even more than sinking. Although the size of a ship is calculated on its tonnage, this is a measure of volume rather than weight. But, despite all of those things and more, the vessel is full of air. Drop them in the sea and the beach ball will float, high in the water.

A combination of natural physics and human engineering allows us to experience giant cruising vessels. The science of the modern cruise ship’s U-shaped hull balances the force of gravity above and the push of the waters below. Now that you know how cruise ships float, you can marvel at the feat of engineering while you relax as a passenger on the deck.

The electricity is used to power the ship’s propulsion systems, lighting, air conditioning, and other onboard systems. Some vessels use two or more stabilizers depending on the size of the vessel. They are effective at all speeds and also when the vessel is at rest. It is highly effective at slower speeds and since there is no additional structure protruding out of the vessel there are no additional drag forces created on the hull making it more efficient. Near to completion of a vessel, an inclining test is carried out to assess the stability of the vessel. The primary aim of the experiment is to find the center of gravity, and the metacentric height (used as an indicator of stability), and further estimate the stability of the vessel.

The marking on the centre of the vessel’s side is what is commonly known as the Plimsoll mark or load line. It is named after Samuel Plimsoll who campaigned for a safe maximum draft mark, which was enacted in 1875.

During the drill, passengers are shown how to use life jackets and given instructions on what to do in case of an emergency. Once the ship is secured, passengers can disembark and explore the port. Cruise ships typically spend a day or two at each port, giving passengers plenty of time to explore the local attractions. While the movement looks effortless, there is a great deal of engineering beneath the surface keeping it afloat. Boats have a "v-hull", which means if you took it out of the water and looked underneath, the bottom resembles the letter "v". While the ship is indeed quite heavy, there is a lot of open space onboard and that empty volume means the ship is not like a giant rock in the water.
