"For the power source, I'm thinking of this, which you know very well, Jin-dono.

Jin nodded as he looked at the plans Christophe had unfolded. He was indeed familiar with it.

"Yes. This is originally used for the propulsion engine of a hot air balloon, but we are going to use it for a boat."
Christophe explained that they had thought about changing to a submersible model, but the diameter of the jet side was too narrow and would be easily clogged with water plants and debris, so they decided to generate propulsion in the air.
He did not come up with the idea of using a boundary to prevent solid objects from being sucked into the jet, as Jin had done.

However, I do not think this is a problem for Jin either. Even on the modern Earth, there are boats that are propelled by propellers in order to run in places where there are a lot of water plants and algae.
"So we are going to use three to four of these wind thrusters.
"I see, that sounds good."

Christophe broke into a smile as Jin, the developer, nodded.
"...... and I would like you to proceed with the study of the hull on the assumption that we will use these wind magic propellers (wind thrusters) for the propulsion system."
"Then, the mounting position would be a problem. How about between the two hulls of a catamaran?

Rodrigo immediately spoke up.
"Yes, that's not a bad idea.
"...... I think a little higher would be better. I think it would be easier to maintain and we can change the direction of travel by changing the direction of the wind thrusters.

"I see."
It was an idea that could cover the shortcomings of a catamaran, which is inferior in maneuverability.
"No, that means the suction port will be on the deck, so what if the crew gets sucked in?

Now, some people pointed out the danger.
"Then, why don't we put a net in front of the suction port?
"No, no, no. If we generate propulsion too high up, the ship may become unstable.

The discussion became heated right from the start.
Jin, who was participating in the meeting from a step, or rather, a half-step back, was taking it easy, thinking that this kind of atmosphere was also good.
However, he was not so sure.

"I'm telling you, if you want to be safe, you have to find a way to do it!
"No, I'm saying that such a way of thinking will reduce the propulsive force.
You just have to be creative!

You do things you don't have to do, that's called waste!
"What's wasteful? You are an engineer, aren't you?
Things started to get heated up. Mainly Claire and Xenelos.

Jin watched the argument between them and thought that Claire, on the other hand, had red hair and looked somewhat like Bina.
"......Let's stop the debate for now."
Christophe half-heartedly stops the exchange, which could have gone on forever if left unchecked.

"I think it would be better to hear the opinion of Mr. Jin, the inventor of the Wind Thruster.
At these words, the attendees all turned to Jin, and he was a little overwhelmed. But if we are talking about technology, it is Jin's field.
"In terms of efficiency, I think it is better to make the flow and wind paths as straight as possible.

Xenelos looks proud of himself when he hears this, which seems to irritate Kreia again.
"Uggg ......."
Clenching his small fists in frustration, Kreia stared alternately at Jin and Xeneros, but said nothing more and sat back in his seat.

"However, I think it's a good idea to have the flow diverge only when changing direction," he added.
Claire now looked pleased at Jin's comment.
"Then, this wind magic propulsion system (wind thruster), right? I think this should be installed under the deck connecting the two hulls.

Now Rodrigo opens his mouth.
"No, in that case, a catamaran would not be suitable for this application.
I heard a rebuttal. It was Cubalt, a shipbuilder (shipwright) from the town of Simos, who spoke up.

"Because of the strength required for such an application. This would be a disadvantage in terms of one of the planned applications, <
"I see. ......"
Rodrigo seemed to have the capacity to listen to the opinions of others.

After many more opinions were exchanged, a silence fell as everyone was deep in thought.
"Well, I am pleased to see that so many opinions have been expressed since the first day. The time is just right, so let's have lunch.
Christophe clapped his hands together.

Lunch was served from a nearby hotel.
The delivery was delivered to the common room, which was set up separately from the conference room.
As is typical of the lakeside area, the set menu consisted mainly of river fish. Of course, there is no need to worry about parasites since the fish is cooked with heat ...... or rather grilled with salt.

Jin, Erza and Reinhard had no complaints about the taste.
"......No, I'm surprised. It's been heated right from the start."
Reinhardt said as he sipped his after-dinner tea. Jin nodded.

"Yeah. "Yeah, but it's interesting. Being involved in this kind of development is instructive.
"...... Jin, even my brother thinks like that?"
Erza looks at me curiously.

"Yeah. "Yes, that's right. People who think differently sometimes point out things to us that we didn't expect. And often it's something I've missed.
"So, what do you think about catamarans, Jin?
"Well, that's the thing..."

Jin's voice trails off at this point.
"......I remember that there were few large catamaran ships in my world. There are advantages, but there are also disadvantages, I guess.
Hearing this, Reinhardt decided to answer from the standpoint of a politician rather than an engineer.

"Certainly, as a budget provider, I would like you to avoid new innovations in everything, wouldn't I?
"What do you mean by that, brother Rai?"
Elsa asked, unsure of the meaning of the question.

"Well, you know what I mean when I say ...... construction and operation experience, don't you? It means that we can't simply build something without a proven track record with taxpayers' money, even if it is built by a private individual.
In reality, the project is not something that has never been done before, but rather a cautious approach that builds on the existing achievements.
"...... I kind of get it."

"Right? After pouring a lot of money into a product and testing it extensively, it's unacceptable if it's not very useful.
Erza glanced at Jin.
"...... In that sense, Jin, you are a foul."
Read at https://w w w . m t l r e a d e r.com
"Haha, that's harsh. Haha, that's harsh, but I think you're right. Reinhardt is a manipulative fool like me, but he differs from me in that he has such a political eye.
Erza giggles.
"So, brother Jin, brother Rai, are you both against the catamaran?"
Read at https://w w w . m t l r e a d e r.com
"Yes. I'm sorry to hear that.
They both answered in unison.
"...... I see, that's too bad."

Jin heard a voice behind him and turned to see Rodrigo standing there with a cup of tea in his hand.
"Ah, Mr. Rodrigo. "Oh, Mr. Rodrigo, I'm not denying the catamaran. Just ......."
But Rodrigo interrupted Jin with a wry smile.

"No, Jin-dono, I'm not complaining. What you say makes sense, and Reinhardt has a good point.
Rodrigo is not a self-satisfied engineer, perhaps because he is in his mid-forties.
"Even I have never built a ship as large as this one. I have just realized what Mr. Jin said about the force applied to each part of the hull changing depending on the waves. My hat is off to you."

"......Oh, that sounds interesting."
Then Couwald joined in.
"So, what are the requirements for designing a large ship?"

After drinking tea from the cup in his hand, Couwald looked at the faces of Jin and the others in turn, and then raised a question.
"Stability, resilience, strength, habitability, mobility, maintainability, fuel economy ......, there are many things."
This is Jin. Couwald rolled his eyes when he heard those words.

"Haha ......! That's the Magecraft Meister! I didn't expect such an immediate answer. I've been thinking about this since it came to me, and I agree with you. I have been thinking about it since it came to me and I agree with you. ...... and I didn't even notice the conservatism."
Then came Christophe.
"You have an interesting conversation going on here, but I would like to continue it in the conference room," he said.

There was no disagreement among the participants, and after Jin and the others had finished their cold tea, they all moved to the conference room.
