"Don't expect communication equipment, this technology tree will not be there before it is opened, the host can only choose a fast sailboat, there is a competitive sailing ship of the era you came from, the speed is very fast, it is very expensive, you can use it as a communication ship and a VIP transport ship."

As he spoke, a video of a high-speed racing sailing boat appeared on the light curtain, as well as three-dimensional drawings and data. Let's start by looking at the prototype of this ship, the "Hydrofoil". The fast sailing boat I recommend to you is an enlarged version of the optimized design based on this.

The Hydroptère is a 21st-century hydrofoil sailing yacht with a trimaran shape with a cross/crossbow in the middle and two small hulls under the top of the crossarms, the main hull is 60 feet long. When at sea, like a seaplane with its wings outstretched and ready to take off, this fearsome boat has set the highest speed ever achieved in a competitive sailing yacht at over 60 knots (111 km/h).

There was a group of madmen who built a boat that could "fly" on water, and their design goal was to create a high-speed sailboat that could sail around the world in 40 days. The 60-foot (18.28-meter) long, slender hydrofoil of the trimaran shaped 60-foot (18.28 meters) long and slender hydrofoil is like an airplane with its wings stretched out for takeoff, and its entire hull is almost floating on the water, as if gliding against the surface of the water - the Hydrofoil is perhaps the fastest ship in the world. It has set a world record for an average speed of 51 knots, and at the other extreme, when the trimaran capsized, it continued to sail a long distance at more than 60 knots (about 111 km/h).

Hydrofoil is a type of ship that relies on the hydrofoil installed in the lower part of the hull to generate hydrodynamic lift and lift the hull out of the water during high-speed sailing. By minimizing the drag of the water on the boat itself, hydrofoils tend to achieve extremely high speeds that make it look as if they were flying over water.

As the speed of the boat gradually increases, the buoyancy provided by the hydrofoils at the bottom of the boat (which look like two metal sheets, but are actually made of high-strength carbon fiber) lifts the hull off the water, greatly reducing the drag of the water and increasing the speed of the voyage. This design uses an airplane-like principle to allow the 18-metre ×24-metre-like trimaran with wings outstretched to reach speeds that are unattainable by other vessels.

Manoeuvring such a fast sailboat requires a very experienced and competent team, and the crew must be able to endure being squeezed into the narrow cockpit with their companions under the "onslaught" of the water, and then "climbing" through the three hulls of the bunching net like the most dexterous monkey depending on the direction of the wind – no easy task.

Around the globe in 40 days, what a terrible design. Li Jing had never heard of this boat before, after all, he did not have much interest in sailing back then.

"The ship offered to you by the trading platform has three enlarged hulls for the transportation of dignitaries, all three hulls are the same size, and each has a cabin 108 feet (33 meters) long, 12 feet (3.66 meters) wide, and 12 feet high, connecting the three hulls with three pipe-like beams. With a diameter of 1.5 meters and three hulls, the cabin crew can travel through three beams and a half.

Between the three horizontal and three longitudinal hulls is not a deck, but a high-strength rope net. An extra-tall mainmast with two huge sails, one on the mainmast and the other on the line between the mainmast and the bow. The draft is very shallow and can be navigated on inland rivers.

It can achieve speeds of up to 100 km/h, albeit at a reduced speed than the Flying Wing. But the hull was greatly enlarged, and it could carry 30 people and carry enough supplies around the world. The sea route from Jinling to Meihuawu is less than 1,600 kilometers away and can be reached on the same day. Considering the headwind on the way back, even in the worst-case scenario, three days is enough time for a round trip. Under normal circumstances, it is possible to make a round trip in two days. If you only run a short distance, you don't need a lot of supplies, and you can take 60 people.

However, the comfort of this boat is not considered, there are four layers of beds in the three hulls, the waves are crazy on the rope nets, the deck will be wet, the hull shakes violently, and many people who do not often take the boat will vomit all the way to the destination.

However, this boat is very suitable for transportation boats, VIP carriers, and mail carriers. Although there are no weapons, do you still need weapons for this speed? In addition to the crew, the transportation capacity of 60 people and the cargo capacity of three tons of cargo are also enough to buy enough for Li Jing's needs.

"How many coins," Li Jing said through gritted teeth.

"500,000 yuan, no way, it's not that I don't give you a preferential price, mainly because although this is a sailboat, the materials are all carbon fiber, the rigging and control machinery are hydraulically assisted, and the design is also very scientific. However, because you are lucky enough to open the high-end price, there will be such high-end products from time to time. ”

Li Jing felt that his eyes were black, 500,000 coins, except for buying a shuttle, he had not spent more than 1,000 coins. "Isn't there any promotion, if not, forget it, I'd better upgrade the tech tree slowly"

The customer service sister is obviously a little anxious, this is a big order, obviously her commission is also a lot, tangled and said: "I can apply, send a 166-ton three-mast luxury yacht to you, aluminum alloy and stainless steel hull, clipper design, the speed can reach a maximum of 15 knots, the front mast with a spinnaker, crosssail, longitudinal sail mixed sail." Five-star furnishing, three decks, nine bedrooms, a living room, a kitchen, the main deck with a small circular open-air bathtub and sunbath leather sofa deck cushions. This is a sister saint. ”

"Yachts are for fun, and they can't make money to transport goods," Li Jing complained

"The host can think about it, take your four little maidservants, and the host can also order a crew team composed of beautiful bodyguards, captains, sailors, and cooks, put on swimsuits, bikinis, uniforms, and drink Lafite, isn't it very comfortable to relax at sea," the customer service sister said seductively, and unintentionally exposed/out of the big / long / legs under the high slit / cheongsam "It seems that the customer service sister is also fighting in order to promote this second largest order in history."

"Well, you managed to convince me," Li Jing said depressedly.
