Have you noticed how ships, both large and small tend to be painted a different color under the water, most often it is red but actually nowadays you can get any color you like.

Video: Why A Ship’s Bottom Is Mostly Painted Red

A lot of people may think that there is no apparent reason for a ship to be painted in an area which is always under the waterline where nobody sees it. Either way, have you ever wondered why most of the ships are painted with red color on the bottom?

Well, one of the answers is tradition. Shipping is a tradition-oriented industry and as you must be aware that all ships are called ‘She’ based on an old nautical tradition. But tradition is not the only reason for painting the ship’s bottom red, there is science behind it.

The reason for it goes back to the earliest days of sailing ships, back in those days wooden sailing ships would travel around the world slowly, a combination of their slow speed and rough hull made them an ideal breeding ground for underwater growth. Just take a look under a pier, you will see the sort of growth these ships used to suffer, we are talking about the barnacles, worms, seaweed and other micro-organisms.

Now you might wonder, what’s the issue with such growth on the ship’s hull? Well, this muck not only impairs the vessel’s structure but also increases the drag. That means the ships wouldn’t move as fast as they could, or they might use more fuel while getting through the water.

The sailors in those early days, used to cover the hulls (the part sitting in the water) of their boats/ships with copper paint to protect the vessel from unwanted wood-eating worms, barnacles, sea-weed, etc. It was the copper that added a red tint to the paint. Thanks to this substance, ships could stay intact and wouldn’t be weighed down by all the unwanted stuff collected on the hull below the waterline.

Nowadays, you can add special ship-protecting ingredients (Anti-fouling coatings) to any kind or color of paint. But the hulls are still painted red to honor and maintain the old nautical tradition.

Another reason can be traced in the contrast of red hull to the sea water, which demonstrates if the ship is overloaded. The more cargo a ship is carrying, the deeper it enters the water and the red color is the demarcation line (Plimsoll line).

In the same context of ‘contrast’, the red color at sea can be very easily captured by passing-by helicopters in case of an emergency.

US defends use of phrase 'Indo-Pacific', says it reflects India's rise

US President Donald Trump on Sunday began his five-nation tour through Asia.

Washington: The Trump administration on Sunday defended the use of 'Indo-Pacific' phrase instead of 'Asia Pacific', saying it captures the importance of the rise of India.

"We have strong and growing ties with India. We talk about 'Indo-Pacific' in part because that phrase captures the importance of India's rise," a senior White House official told reporters in Tokyo.

"It (Indo-Pacific) captures the importance of the maritime free commons that allow our security and our prosperity to continue," the official added.

He was responding to queries on the increasing use of the phrase 'Indo-Pacific' by the Trump Administration, its talk about free and open trade in the region and how the Chinese should regard that.

The White House official further said on condition of anonymity that the strategy was 'certainly' not to contain China. PTI reported

Reaffirming that the United States is a Indo-Pacific power, the official said America's security and prosperity depends on the US maintaining access for free flow of commerce to this region, because it is a Pacific nation.

To a question on talks about a strategic dialogue between India, Japan, Australia and the US, the official said this is not about containing China.

"On the question of cooperation between allies and partners, the US is always talking very closely, from the leader level all the way down to our close allies, Australia and Japan. That is longstanding," the official said.

Neither the US nor Australia or Japan have a security alliance with India, the official said, adding, "India is an increasingly important security partner, no doubt. It's natural that they should be, given that they are really, sort of, conceptually the western edge of the Indo-Pacific region, the United States making up the eastern edge of that."

"India to the west, the United States the east," the official said.

Trump lands in Japan:

Meanwhile, US President Donald Trump ramped up his tough rhetoric against North Korea when he arrived in Japan on Sunday, saying that the United States and its allies are prepared to defend freedom and that 'no dictator' should underestimate US resolve.

He told reporters on Air Force One en route to Asia that North Korea would figure prominently in discussions during the trip, as per Reuters.

Trump also singled out trade, which he said had been 'badly handled' in the region for years.

After Japan, he will head to South Korea on November 7 where he will visit Camp Humphreys, a US military complex south of Seoul but will not go to the heavily fortified demilitarized zone (DMZ) on the border between the South and North.

Trump will then visit China on November 8 where he will participate in a series of events with his counterpart Xi Jinping.

In Vietnam (November 10-11), he will attend the Asia-Pacific Economic Co-operation summit in Danang and make a state visit to Hanoi. He is likely to meet his Russian counterpart Vladimir Putin here.

His final engagement will be a summit of South-East Asian nations in the Philippine capital, Manila (November 12-13).
