Magi Craft Meister

Ship lectures by Jen continue.

"The resistance of water added to the ship is' wave resistance 'and' viscous friction resistance ', plus' viscous pressure resistance '." Wavebuilding resistance is a force used by ships to create waves, and think of' viscous friction resistance 'as a sticky water. "

Jen, when building a model ship, it is shallow because it is the knowledge purchased in the model magazine, and there are holes everywhere, but no one else in this world can provide a systematic explanation so far.

"'Viscous Pressure Resistance' is the resistance of the lower pressure behind the ship to pull the ship back."

……

Jen also remembers, so I can't go into any further detail. Nevertheless, fortunately, all the 'students' I hear were practitioners.

"If you move your hand in the water, the resistance would be greater if you were spreading it in the direction of moving your palms, and if you twisted it 90 degrees, the resistance would be smaller, wouldn't it?

These explanations convince me.

"Yeah, I think I got it."

There's no time, so Jen keeps explaining.

"The stability of the ship…"

"The shape of the bottom of the ship…"

"The structure of the hull…"

All received and sold from model magazines, but both Marcia and Prince Ernest listened seriously. And Hannah and Elsa, Lisia, and Rodrigo, too.

"No, Lord Jin's story is quite helpful"

"Your explanation is easy to understand."

"Brother Jin's commentary, I haven't heard it in a while, but about the ship, I understand very well"

"I hope so..."

When Jen looked at Prince Ernest at the heart, he was just writing down what he had heard on leather paper.

"Jin, when you do that, you have to be quite careful when building a big ship."

"Don't be like that."

In this regard, Jen, Elsa and Rodrigo have experience when they built 'Bernstein' in the Shawlo Empire.

"The bigger it gets, the greater the force it takes to hang around the hull. This is good, right?

"Yeah. Wave influence."

"The shape of the bottom is also important."

In this way, Jen explained the basics of every ship he could think of.

I spent about an hour and a half explaining everything, and then I showed the actual product in Marcia's workshop.

"Look, the surface's a bump, isn't it?

"Oh, it's true. To reduce viscous friction resistance."

Common wooden ships use only water-resistant, non-corrosive trees, which are not surface treated or embalmed, but are different here.

"A tree can grow mold and rot when it's wet and touching the air."

"Oh, really?

"That's right. It won't rot if it sinks all the way in the water."

Even with the sunken wreck retaining its shape, I can see that.

"So treat them not to inhale water, and even paint them to play water"

"A big ship would be more necessary."

Come on, I don't want a big ship that can't be rebuilt to rot.

"That way...... that's Marcia's idea, so I won't explain it that far"

but Ernest grinned and nodded.

"Yeah! Of course I do. That's something we should all work out for ourselves."

"It's a small ship, so a double torso (catamaran) or triple torso (trimalan) is effective, but when it's a large ship, the strength of the connecting part becomes a problem."

"Oh, because the waves have different forces across the hull."

"Exactly."

The content of the earlier lecture seemed to have been properly conveyed to Prince Ernest.

Exactly around here, Princess Reeschen seems to have stopped following her and is chatting with Lisia against her.

but Hannah looks serious about not listening to Jen's explanation. She was a princess who seemed a little lonely.

The tightening is to have them on board the ship.

First up is Swan (Signus), who once won.

Pack it and you can ride three critical people.

"Wow, it feels good!

Swans running around the bay (signals) as they face the sea breeze.

"Your Highness, remember this way of shaking, exertion, acceleration, etc."

Marcia told Prince Ernest as he ran the swan (signals) at about 80% of the speed.

This is followed by this winning boat, Zeke 6, as it is. They didn't give it a name.

"Yeah, I know it's different somehow!

One boat body at a time is slightly shorter for the two torso to the three torso, and the small turns are favorable for that amount.

Also, as the distance from each "buoyancy center" increases, the shaking cycle is longer.

"Plus, I'd like to accelerate."

"Yes, that's the effect of this' horizontal waterwheel '…' screw '"

"I see. But if it involves algae or seaweed, it's not good."

Marcia is a little surprised by Prince Ernest pointing out Screw's weakness in a short time.

"... Yes. So you have to be careful where you run."

"If it's a small ship, it can be removed by hand even if it's involved, but I don't know about a large ship..."

He was Prince Ernest, who even thought about that.

"Gin, Marcia, Elsa, Hannah, Lisia, thank you. Laeko, Edgar, Arrow, you took care of me."

And the time is 11: 00 a.m., and the two highnesses bid farewell to Jens.

"I'll have you sent home to the kingdom of Elias, so it's okay."

Princess Rieschen laughs and tells her. She hangs words on Hannah even more.

"Hannah, you're a master. I'll see you around."

"Reese, your sister's fine!

In front of Marcia's workshop there was an array of carriages and escorts arranged by the Marquis of Florenciano.

"I'm sending you both to the capital, Borgia."

Then in "Conlon 3," Jen thought, "but when he listened carefully, the airship said he would pick him up to the hotel.

"Now, if you'll excuse me,"

"Jin, see you later!

"Jin, thank you for your help!

The Marquis and His Royal Highness wave through the window of the carriage, and Jen responds to it.

Then the carriage moved slowly, and departed from before those who were to be dropped off.

"He's gone."

"Mmm."

"I miss you."

"Yeah......"

"Right......"

The time spent busily with friends also ends one day.

Marcia, Elsa, Jen, Hannah and Lisia expressed the loneliness of their parting in each word.
