Live Wilderness Adventure

Chapter 774 Nemo

There are many ways to reach the destination, not one or the other.

There is no terrain blocking Easter Island and Point Nemo, there is only a wide ocean, but this does not mean that Bi Fang has to go straight.

The function of the sail is to use various wind forces to obtain useful power for forward propulsion.

When sailing with tailwinds and crosswinds, it is only necessary to adjust the direction of the sail to obtain useful forward propulsion.

When encountering a side wind with a small angle, the direction of the sail can also be adjusted to convert the side and rear wind force into the side positive force, and sail forward along the zigzag circuitous.

【I see】

【So now it's not actually heading in the direction of Nemo's point? 】

[Obviously, it is like this]

[Now is the time for a detour! 】

"Z-shaped headwind sailing is not a patent for jib sails or schooners. Square sails in ancient and medieval times, and modern vertical and horizontal sails can all sail against the side of the wind, but the angle limit is relatively large."

"In contrast, since the schooner is only hung on one side, there is more room for wind direction adjustment, so it can sail at a larger angle."

"When the angle of the sidewind is so large that the forward wind can no longer satisfy it, it is necessary to consider the tangential wind pull."

"According to the Bernoulli effect, vertical sails, gaff sails, gaff sails, and jibs can obtain greater pulling force, while square sails have almost no Bernoulli effect force."

"However, the tangential pulling force is firstly small, incomparable with the positive force, and secondly, it will cause great damage to the sail, so it is to retain the ability, and it will only be used in extreme cases."

"When Guo Xingye recovered Taishui Bend, the Dutchman's Maria, a gaff sailing ship, sailed against the monsoon. The price was that the sails were basically scrapped when it reached Batavia."

"Needham once summed up the sailing angles of various sails. The sailing ability within 45 degrees is basically on the side against the wind, and the headwind, that is, the headwind is theoretically impossible to sail with a sail."

The essence of modern sailing competition is a competition with extremely complicated technology.

In order to obtain extreme speed, players need to have a comprehensive understanding and control of the wind, ensure that their sails can get the maximum thrust, and also have good physical strength, otherwise they will not have enough physical strength to manipulate the sails during the long game .

[In the past, I only thought it was a handsome sailing boat, but I didn’t expect it to be so particular about it]

[Fangshen still knows a lot. 】

【Who is Needham? Who is the surname of the country? 】

[Needham is a Yangguo scientist, and his Needham's question is one of the core topics in the field of Huaxia studies, which is juxtaposed with Qian Lao's question]

【Needham can still understand if he doesn’t know, it’s a bit boring if the country’s surname doesn’t know】

The jib sail is more conducive to sailing against the wind. There are two main points: one is that it is used as a horizontal sail. It's bigger than a square sail.

Coupled with the ability to use tangential winds, it naturally becomes the most suitable sail type for sailing against the wind among traditional sails.

That's why Bi Fang would install a triangular sail.

"It's just that at the end of the Middle Ages and modern times, the Arab dhow Shebek carried the Barbary pirates to fight in all directions and became the last glory of the Latin sail. and decline."

"In the 19th century, even the Indian Ocean was dominated by gaff sails."

“By the 20th century, Arab local tyrants started a big retro movement, held dhow sports, and preserved the heritage.”

There is enough food, and two fresh water devices have been distilling. It is the first time for Bi Fang to prepare for such a sufficient adventure. He doesn't know what to do for a while, and can only briefly explain the history of sailing to the audience.

【I’ve never fought such a rich battle, have I (laughs)】

Bi Fang smiled, and pointed to the thin rope fluttering on the sail.

"If you don't have an indicator on the top of your mast to determine the direction of the wind, tie some old tape, video tape, or oil line to the shrouds—the lines that pull up the mast—and they'll tell you which way the wind is blowing. where."

"However some sailors find tape too sensitive to wind to be suitable. If you find the same problem, try video tape or oil line."

"Of course, you can also feel the wind direction directly and learn to judge the wind direction with your ears."

"All you have to do is let the wind blow on your back and slowly turn your head back and forth from side to side until you feel your left and right ears 'balanced'. Once you find that point, you know which way the wind is going. With this method, you don't It takes eyes to catch the wind."

[No wonder, I said why Lao Fang tied a rope on the bow, I thought it was some kind of mark]

[Another small detail. 】

【Bulfrog Bullfrog】

"The sea has fascinated sailors and explorers for centuries."

"In the poem "Fever for the Sea," John Masefield says he needs "a great ship and a star to guide her" to feel the fullness of life."

"But entering the world of sailing is undoubtedly challenging. There are so many doors in it. In the past, an experienced sailor was an extremely valuable strategic resource."

Bi Fang put the small fish on the hook and threw it into the sea.

Taking advantage of the lack of complete access to the South Pacific gyre, there are still many fish resources nearby, and you can also experience the fun of fishing, otherwise you may not have this experience in two days.

evening.

Bi Fang put away the fishing line.

It has been sailing for nearly six hours. During these six hours, all Bi Fang can do is adjust the direction of the sail and see if any fish are hooked.

Fortunately, because of the first day of sailing, the audience in the live broadcast room has always remained above 6 million, and the peak data even exceeded 10 million.

The wind on the sea is much lower, and the whole ocean looks dead, which makes people think of the goal of this voyage.

This feeling is very strange. It is obviously an ocean voyage, but this time it seems to be more lonely than the Atlantic Ocean, and there is an indescribably creepy feeling.

[Speaking of which, why is Point Nemo called Point Nemo? Is it named after the person who discovered it? 】

[It always reminds me of the clownfish in Finding Nemo]

"The origin of Nemo's name is actually very particular. Many people may first think of 'Nemo' as the clownfish in "Finding Nemo", but it is obviously impossible."

"But those who have watched "Twenty Thousand Leagues Under the Sea" will never forget the resolute and courageous Captain Nemo, and the name of Nemo Point is a tribute to Captain Nemo."

"Even more fittingly, 'Nemo' means 'no one' in Latin, which is a very fitting name for such a lonely place."
