The big white balls on top of cruise ships are known as radomes, which are a combination of radar and dome. They house radio and satellite equipment used by the ship or boat to communicate with the shore wherever the vessel is on the seven seas. Radomes consist of two parts: a radar and a dome, and are made up of two parts: a radar and a dome.
The main parts of a yacht typically include the hull, deck, mast, boom, rigging, sails, keel or centerboard, rudder, and various other key parts. A standard yacht has several key parts, including a stern, hull, and bow. The stern, or aft, refers to the back of the yacht, sometimes accompanied by a swim platform.
In one of their documents, it states that a black ball day shape must be displayed by ALL vessels when anchored during the day. There are multiple ones because cruise ships are so big that their Seacocks (valves) are an essential part of the underwater skin fitting. Occasionally, the terms ‘skin fittings’ and ‘seacocks’ are used interchangeably, but the seacock is specifically the valve that lets the signal pass through.
An anchor ball is a set of simple geometric shapes—ball, cylinder, cone, and diamond—that are displayed, hung from a mast, in a prescribed manner to let other boats know you are not under power. Anchor balls in boating and yachting can mean two different things.

What is an anchor ball on a yacht?
What Is It?An anchor ball is a round fender with enough buoyancy to support a rode and anchor. A 20-inch-diameter ball has approximately 180 pounds of buoyancy and is the most popular size used by seasoned skippers. To this ball, it’s common to affix a three-foot trace of line (but see tip later). At the other end of the trace, attach a large carabiner snap. To this snap, connect a specialized piece of equipment called an anchor ring.
The TheoryUsing an anchor ball is like heaving a line over a tree branch and connecting one end to a truck’s hitch in order to raise a heavy weight at the other end. Since limbs are rare on the water, run the rode through the ring, which is supported by the buoyancy of the ball. The boat is the truck, the ring and ball the limb.
The PracticeTo haul anchor, place the anchor ring around the rode and snap the line to it. The snap connects the ball and also “closes” the ring, capturing the rode. Now power toward the anchor, angling off just a bit so you’re not quite running parallel to the rode. A good, fast troll that provides confident steerage is fine.
What is the sphere on top of a ship?
The white spheres on the top deck of a cruise ship are satellite dishes in a spherical housing. They provide television and radio signals on board.
On both sides of the ships hang yellow or orange lifeboats that have space for all passengers and crew members on board. The lifeboats can still be subdivided in ‘normal lifeboats’ and ‘tenders’. A tender has been designed in such a way the it can be used to transport passengers to the shore when a cruise ship has to anchor. It can be seen as a taxi. Apart from the lifeboats there are also liferafts on board that can fit a minimum of 25% of all persons on the vessel. That means that the rescue capacity of a cruise ship is a quarter bigger than the total number of people on board. The liferafts are stored outside on deck in white plastic barrels that open when they make contact with water.
This is the exhaust of the ships’ engines. Over the last few years there has been a lot of media attention regarding the air pollution by cruise ships. Although the impression is given that nothing is being done to reduce emissions this is not true. The emission of sulfer dioxide (SOx) and nitrogen oxide (NOx) has already been reduced on the North sea and the Baltic Sea by strict regulations. Apart from that the cruise and ferry branch is also experimenting with new possible fuels like LNG and hybrid-technology. No other maritime branch is this progressive in this search. While looking at environmental pollution one should also not excessively focus on the cruise ships. Currently a total of around 100.000 ships are sailing around the world, but only around 400 of those are cruise ships.
At the front of the ship, behind the bridge, you can find the mast. On it are the radars and several flags. The mast must also always fly the flag of the waters the ship is currently in. A ship that is on its way to Antwerp will exchange the Dutch flag for the Belgian flag at the border.
What are the balls on ships for?
But there will also even out the force. Felt by the compass needle allowing it to rotate smoothly. Around its full 360 Degrees.
What is the purpose of an anchor ball on a yacht?
The alternative type of Anchor Ball, is one where a ball fender is attached to support a rode and anchor using an anchor ring. Using the Anchor Ball as a kind of pulley by powering towards then past the location of the anchor on the seabed, allows the anchor to be brought to the surface by the buoyancy of the ball fender, where it can then be easily hauled onto the boat.

What is the ball on top of a yacht?
Would attract heat from the Sun. And could cause problem for the equipment inside. And all cruise ships have radar. But not all have radon some ships may have their radar equipment out of sight.
What is the purpose of the bulbous bow?
Bulbous bow can help to reduce a ship’s resistance and thus to save the fuel consumption up to 15%, however, it is also regarded as a threat to a struck ship in collision accidents because it may generally penetrate the side shell of the vessel, which may cause the leakage of hazardous goods.

Why is there a ball on the front of ships?
This is reduced the drag and it’s reduced the fuel consumption. And this is the main reason for fitting a bulb. If we remember back to the start of the video we saw the old bulbs are different they’re.
What are the large balls on top of cruise ships?
The big white balls on top of cruise ships are Radomes. A Radome is made up of two parts, a Radar and a Dome, hence the name Ra-dome. The dome covers the radar equipment protecting it from the weather and hiding it from guests. A radome can also include satelitte equipment.
Radomes contain rotating radar antennas and satellite discs, which will be constantly on the move. Radomes are designed to allow movement not only from the radar itself but also from the ship. The ship is subject to movements caused by weather and the ocean, so it is critical that the Radome is large enough to allow this movement.
The satellite equipment held within Radomes is used for communication, entertainment and navigation purposes.
What are the big balls on top of ships?
What are the big balls on cruise ships?. The big white balls on cruise ships are known as radomes. The name is “a portmanteau of the words ‘radar’ and ‘dome,'” says Beau Ragland, CEO of unique travel experience company Voyista Travel. According to Ragland, the protective dome shields the sensitive radar antenna from the elements and the corroding effects of saltwater.
Radomes’ position on the unobstructed top of the ship makes it easier for the equipment to work properly. Anyone who’s been on a boat—be that a fishing vessel, Disney cruise, singles cruise or any other ship—knows that the open sea can be a challenging environment. Radomes spend most of their time battling high winds, storms, salt spray, sunlight and seabirds. As such, they’re made of high-performance materials, allowing them to function properly despite harsh seafaring conditions.
What are radomes used for?. According to Elaine Warren, founder and CEO of The Family Cruise Companion, a travel blog that specializes in (no surprise here) family cruises, radomes allow cruise ships to stay in touch with shore-side systems and other ships via radar. “They even help the ship move more efficiently by reducing wind resistance,” she says.
