There are many ways to reach your destination, it's not either/or.

There is no terrain barrier between Easter Island and Point Nemo, only a wide ocean, but this does not mean that Bifang must move forward in a straight line.

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

When sailing with tailwind or crosswind, you only need to adjust the direction of the sail to obtain useful forward propulsion.

When encountering a small side headwind, you can also adjust the direction of sailing, convert the side-back wind force into side-forward force, and sail forward in a zigzag manner.

[I see][So it’s not actually heading towards Point Nemo now?][Obviously, that’s the case]

[Now is the detour moment!]

"Zigzag sailing against the wind is not exclusive to triangular sails or longitudinal sails. Ancient and medieval square sails and modern vertical and horizontal sails can sail in side headwinds, but the angle is limited to a relatively large one."

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

"When the angle of the side headwind reaches a certain level and the forward wind can no longer satisfy it, the tangential wind pull must be considered."

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

"However, firstly, the tangential pulling force is not large and cannot be compared with the forward force. Secondly, it causes great damage to the sail gear. Therefore, it only retains its ability and will only be used in extreme circumstances."

"When Kuo Xingye recaptured Tai Shui Bend, the Dutch ship Maria, a gaffed sailing ship, sailed against the monsoon wind. The cost was that the sails were basically scrapped when they arrived in Batavia."

"Joseph Needham once summarized the sailing angles of various sails. The sailing ability within 45 degrees is basically sideways and against the wind, while it is theoretically impossible to sail directly against the wind, that is, with the wind in your head."

Modern sailing competition is essentially an extremely technically complex competition.

In order to achieve the ultimate speed, players need to have a comprehensive understanding and control of the wind to ensure that their sails can obtain maximum thrust, and they also need to have good physical strength. Otherwise, they will not have enough physical strength to control the sails in a long race.

[I used to think that pulling a sailboat was a handsome guy, but I didn’t expect that there are so many things to pay attention to] [Fang Shen still knows better.] [Who is Joseph Needham? What is the surname of the country?]

[Joseph Needham was a Yangguo scientist. His Questions about Needham and Lao Qian’s Questions are one of the core topics in the field of Chinese studies]

[If you don’t know Joseph Needham, you can still understand it. If you don’t even know the country’s surname, it’s a bit confusing]

The triangular sail is more conducive to sailing against the wind. There are two main reasons: first, as a square sail, the two sides of the triangular sail are asymmetrical, and the direction of force is twice as much as that of the square sail. You can sail at the applicable angle of the fore and aft sail, and the sailing range is

Just bigger than a square sail.

Coupled with the fact that it can take advantage of tangential wind, it naturally becomes the most suitable type of sail for upwind sailing among traditional sails. This is why Bifang installed a triangle sail.

"It's just that in the late Middle Ages and modern times, the Arabian dhow Shebek carried the Barbary pirates to conquer all directions, becoming the last glory of the Latin sail. With the advancement of European shipbuilding and firearms technology, at the end of modern times with the destruction of the Barbary pirates

And decline."

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

"In the 20th century, Arab tycoons began a vigorous retro movement and held the triangular sailing sport to preserve the heritage."

There was plenty of food, and the two fresh water devices were still distilling. It was the first time for Bifang to prepare for such an adventure. He didn't know what to do for a while, so he could only briefly introduce the history of sailing to the audience.

[I have never fought such a rich battle, right (laughing)] Bi Fang smiled and pointed at the thin ropes flying on the sail.

"If you don't have an indicator at the top of your mast to determine the direction of the wind, tie some old tape, video tape, or oil line to the shroud—the rope that holds the mast up—and they will tell you which way the wind is blowing. where."

"However, some sailors find that tape is too sensitive to wind and is not suitable. If you find the same problem, you can 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, then slowly turn your head 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 blowing. With this method, you don't It takes eyes to catch the direction of the wind.”

[No wonder, when I asked why Lao Fang tied a rope to the bow of the ship, I thought it was some kind of mark] [Another small detail.] [Bullfrog Bullfrog] "For centuries, the ocean has fascinated sailors and explorers. They."

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

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

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

While we haven't completely entered the South Pacific Gyre now, there are still many fish resources nearby, and we can still experience the fun of fishing. Otherwise, we may not have this experience in two days.

In the evening, Bi Fang put away the fishing line.

It had been sailing for nearly six hours. During these six hours, all Bi Fang could do was adjust the direction of the sail and see if any fish had taken the bait.

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

The wind on the sea has become much lighter, and the entire ocean looks dead, which makes people think of the goal of this voyage.

This feeling is very strange. Although we are sailing on the ocean, this time it seems to be even more lonely than the one on the Atlantic Ocean. There is an indescribable and creepy feeling.

[By the way, 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. When many people see 'Nemo', their first reaction may be the clown fish in "Finding Nemo", but it is obviously impossible."

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

"What's more appropriate is that in Latin, 'Nemo' means 'no one'. For such a lonely place, this is undoubtedly a very suitable name."
