The draft (or draught) of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel), with the thickness of the hull included; in the case of not being included the draft outline would be obtained. Draft determines the minimum depth of water a ship or boat can safely navigate. The draft can also be used to determine the weight of the cargo on board by calculating the total displacement of water and then using Archimedes' principle. A table made by the shipyard shows the water displacement for each draft. The density of the water (salt or fresh) and the content of the ship's bunkers has to be taken into account. The closely related term "trim" is defined as the difference between the forward and aft drafts.


Drafts of a ship

The draft aft (stern) is measured in the perpendicular of the stern.
The draft forward (bow) is measured in the perpendicular of the bow.
The mean draft is obtained by calculating from the averaging of the stern and bow drafts, with correction for water level variation and value of the position of F with respect to the average perpendicular.

Large ships

Larger ships try to maintain an average water draft when they are light (without cargo), in order to make a better sea crossing and reduce the effects of the wind (high centre of velic force). In order to achieve this they use sailing ballasts to stabilize the ship, following the unloading of cargo.

The water draft of a large ship has little direct link with its stability, the latter depends solely on the respective positions of the metacenter of the hull and the centre of gravity. It is also true however, that a "light" ship has quite high stability which can lead to implying too much rolling of the ship (due to memory). A fully laden ship (with a large draft) can have a strong or on the contrary, a weak stability, depending upon the manner by which the ship is loaded (height of the centre of gravity).

The draft of ships can be increased when the ship is in motion, a phenomenon known as squat (nautical term for the hydrodynamic effect of lower pressure pulling the ship down as it moves).

Draft is a significant factor limiting navigable waterways, especially for large vessels. Of course this includes many shallow coastal waters and reefs, but also some major shipping lanes. Panamax class ships—the largest ships able to transit the Panama Canal—do have a draft limit (and an "air draft" limit for passing under bridges) but are usually limited by beam, or sometimes length overall, for fitting into locks. However in the much wider Suez Canal, the limiting factor for Suezmax ships is draft. Some supertankers are able to transit the Suez Canal when unladen or partially laden, but not when fully laden.
Canals are not the only draft-limited shipping lanes. A Malaccamax ship has the deepest draft able to transit the very busy but relatively shallow Strait of Malacca. There are only a few ships of this size.

Pleasure boats

A small draft allows pleasure boats to navigate through shallower water. This makes it possible for these boats to access smaller ports, to travel along rivers and even to 'beach' the boat.

A large draft ensures a good level of stability in strong wind, as the centre of gravity is lower (ballast over the keel of the boat). For example: Ballasts placed very low in the keel of a boat such as a dragon boat with a draft of 1.20 m for a length of 8.90 m.

A boat like a catamaran can mitigate the problem by retrieving good stability in a small draft, but the width of the boat increases.

Submarines

For submarines, which can submerge to different depths at sea, a term called keel depth is used, specifying the current distance from the water surface to the bottom of the submarine's keel. It is used in navigation to avoid underwater obstacles and hitting the ocean bottom, and as a standard point on the submarine for depth measurements.

Submarines usually also have a specified draft used while operating on the surface, for navigating in harbors and at docks.

Nothing to worry actually.

This Chinese captain of the ship will not be along for many years to plague the oceans with his incompetence.

He will be spending a long time in China doing 're-education through labour'.

The People's Republic of China employs several forms of corrections for people who have been arrested, of which re-education through labor is one. The Laogai Research Foundation classifies re-education through labor as a sub-component under the umbrella of the laogai ("reform through labor") criminal justice system,[2] which generally refers to prisons, prison farms, and labor camps for convicted criminals. Re-education through labor, on the other hand, refers to detentions for persons who are not considered criminals or have only committed minor offenses.[3][4] Persons detained under re-education through labor are detained in facilities which are separate from the general prison system; furthermore, detainees in these re-education facilities receive a small salary, which laogai detainees do not, and in theory have shorter work hours.[3] The laogai system is much larger than the re-education through labor system, with the Laogai Research Foundation identifying 1,045 laogai camps in 2006 (compared to 346 re-education centers).[2] Both systems, however, involve penal labor and often do not allow trials or judicial hearings.[5] The term "reform through labor" or laogai was officially replaced with "prison" in 1994,[6] and the term "re-education center" or láojiàosuǒ (劳教所) was replaced with "correctional center" in 2007.[1]

From wiki

In 1999, Malaysia occupied Gabriela Silang Reef (Erica Reef) and Pawikan Reef (Investigator Shoal), causing the Philippines to protest further. Due to this pressure, with China's Mischief Reef just 130 miles (210 km) off Palawan and Vietnam's Pigeon Reef and Malaysia's Investigator Shoal just 150 miles (240 km) off Palawan, the Philippines decided to occupy Ayungin Reef (Second Thomas Reef) in 1999. No structure is built on the reef. Soldiers stationed there take shelter at BRP Sierra Madre, a Philippine naval ship that went aground in the reef shortly before the Philippines decided to occupy it.[9] Together with Rizal Reef (Commodore Reef), Ayungin Reef can give the Philippines a sentry advantage in stopping other countries' occupation of features nearest to the Philippines (see map below).
Any inspiration from what brilliant Filipinos did??

Let's check where the Half Moon Shoal is and how it looks



A 10sqkm lagoon, 27m deep avgly, with a 100m wide gateway - Is it ideal to be built into a naval base and shelter for trawlers?

Admire the Filipinos IQ , this position completely block in Philippines,

A catastrophe be to Filipinos

If you do not fight Chinese, maybe Philippines can get more benefits,

China in the boundary demarcation, the trust States, such as North Korea and Burma, gave a lot of concession

First, if I were a Filipino, instead of laughing, I would feel deeply embarrassed that a Chinese warship could park at a place so close to the shore and many more are coming to rescue without any approval and protesting.

Second, if this is truly an incident, as a Chinese I would question how come a modern warship could end up like this? Is this an isolated incident or systematic problem? It's an embarrassment too.

Third, some Indian members may take this opportunity to entertain themselves. But it's just equally laughable and pathetic when other people make fun of India when she got her own accident.

Well, you may not care what we think.

But then the world does not care what China thinks.

Which is more effective - a single nation, China or the rest of the world?

China call itself the 'Middle Kingdom'.

Well stay in the middle and stop expanding all over the place.

Cancer is the thing that spreads rapidly!

If you do so, then you will ruin your history.
We do care, but who care what you said, who are you?

Philippines Says China Warship Is in Its Territory

Philippines Says China Warship Is in Its Territory - ABC News

The Philippines says a Chinese warship entered an area it claims in the South China Sea and ran aground on a shoal, as tensions continue between the two countries over a separate territorial dispute.

Foreign affairs spokesman Raul Hernandez said Saturday that Manila wants Beijing to explain why the Chinese frigate became stuck on Half Moon Shoal, about 110 kilometers (70 miles) from the western province of Palawan.

"We need to find out what really happened with the Chinese frigate in our territory," Hernandez said.

He said the Philippine Embassy in Beijing has been instructed to inform China's Foreign Ministry that Manila is "willing to help the frigate get out of there."

Defense department spokesman Peter Paul Galvez said a military aircraft spotted six other Chinese ships near the stricken vessel on Saturday.

"We are seeking a clarification from the Chinese what these ships are doing in the area, though it can be assumed that these are out for rescue," he said.

China's Foreign Ministry said in a brief statement on its website that no one was injured when the accident occurred Wednesday as the ship was patrolling near the shoal.

Brig. Gen. Elmer Amon, deputy chief of the Philippine military's Western Command, said the frigate appeared to be in distress and a coast guard vessel had moved within sight of the ship to provide any assistance.

He said the outcropping, called Hasa Hasa Shoal in the Philippines, is well within Manila's territory.

Earlier this year Manila and Beijing became locked in a tense monthslong naval standoff at Scarborough Shoal, another area claimed by both nations in the South China Sea, after the Philippines accused Chinese fishermen of poaching in its waters.

Scarborough is about 710 kilometers (435 miles) north of Half Moon and 235 kilometers (145 miles) off the province of Zambales northwest of Manila.

Funny.

I thought snakes have forked tongue and not the Chinese.

First it is said, you don't care and now it is being said, you care.

Schizophrenia?

Or are the people daft?

Why are you being so prickly.

Something upsetting you in the wrong part of the anatomy?

Who am I?

A citizen of India who can express his view without being worried of being jailed and without worrying that I will be indoctrinated to the Communist Chinese partyline!

Not a robot as the Chinese!

That's who I am!

Like?

Any example?

The Chinese ship running aground was no accident.

It was poor and incompetent seakeeping!

North Korea and Burma are China's trust states? Now other countries should understand what happens to China's "trust states"! :pft:

I guess that rules out an intentional grounding. Chinese captains just don't know how to navigate? Or Beidou isn't very good! :rolleyes:

Chinese frigate safely refloated

he forward hull of the ship was slightly damaged, but all crew members were safe and the ship will sail back to port, according to a news release on the Ministry of National Defense's website.

"It has not caused any contamination in the waters," the statement said.

The frigate has been in service for 19 years and is still in its "prime of life", said Li Jie, a navy analyst in Beijing, refuting speculation that the frigate's stranding was planned.

The Philippines has dispatched one navy and one coast guard ship to the area to monitor the Chinese operations, according to AFP.

Overlapping claims to the islands in the South China Sea have caused tensions in the area. The Philippines, Malaysia, Vietnam, Indonesia and Brunei all claim sovereignty over some islands in the South China Sea.

Chinese and Philippine officials are seeking a resolution to the standoff over Huangyan Island, which has lasted for more than three months, according to The Associated Press.

The Philippines on Sunday said it would not lodge a diplomatic protest after China extricated the naval frigate, which had been stranded for four days, AFP reported.

30-vessel fishing fleet arrives in Nansha

A fleet of 30 fishing vessels from China's island province of Hainan arrived at a fishing venue of Nansha Islands in the southern-most of China's territory Sunday.

The fleet, the largest of its kind from Hainan for the Nansha Islands, arrived at the waters near the Yongshu Reef in South China Sea at about 5 pm Sunday after a 78-hour voyage.

The fleet, including a 3,000-ton supply ship and 29 ships weighing more than 140 tons each, will spend the next five to 10 days fishing near the the Yongshu Reef, sailors of the fleet said.

China Yuzheng 310, a fishery administration patrol ship, has arrived at the area to protect the fishing activities.

Why do we need to fire a shot? Anything is stopping China? Huangyan Island is still under the control of China.

The frigate is gonna stay for a while, then China is gonna build a permanent post there
really is that what your propaganda machine is telling brainless meat puppets?
