So fish are to vegetarian monks, what spiders are to meat-eating philanderers~
Something which they don't eat, and as such must die with prejudice!

 

[Antinomy]

Lmfao, all these people about to almost commit suicide. They're all either brave or stupid. I like how they all made rafts though knowing these Boat Killers will absolutely destroy them. I honestly thought they were just gonna log surf. Maybe MC can make them surfboards instead?

Thanks for the TL

 

[LordofLeechers]

I see...having vegetarians go on endless diatribes as a means to repel hostiles is genius.

At least based on what's been said, I think the idea seems to be:
-since raft float via buoyancy, a hole in it isn't as big of an issue as on a boat
-with how thick the logs are the fish can't break through in a hit

Which...fair? They're only hunting within the time limit anyway and not like they'll reuse the raft multiple times.

Surfboard would be even more vulnerable to these fishes if anything.

die looking faboolas

Damn, vegans are in every society huh. Hope they don't form a vegan organization in the future..

 

[dankenglish]

Seems like the isekai meme where strong adventurers all have odd personalities exists here, too

Thanks for the scanlation

-since raft float via buoyancy, a hole in it isn't as big of an issue as on a boat

Rafts and boats float on the same Archimedes Principle; they displace more water than they weigh. "Buoyancy" is the force acted against the object, be it a raft or boat.

-with how thick the logs are the fish can't break through in a hit

The characters say the fish can punch a hole through 10cm of iron so doubt. The same page has one of them mention the other being her main job, the one complaining about her nails.

 

[Shinigamisama]

This seems like a funny filler arc. And Mercia already missing her partner, how cute.

 

[Haezer]

He's going to get involved with the all-girls party that's for sure.

Yes they float using the same principle, but note that boat's buoyancy requires the empty space in the middle vs raft's just the natural buoyancy of the logs.

One of those will sink with a hole, the other not.

Also just because it can pierce through 10 cm of iron doesn't mean it can pierce through thicker thing without getting stuck (which would leave it an easy target)

Yes they float using the same principle, but note that boat's buoyancy requires the empty space in the middle vs raft's just the natural buoyancy of the logs.

You're not understanding the principle. Any object that displaces more water than it weighs will float due to buoyant forces. A brick of metal won't float but a sheet of metal of the same weight will.

Dried or old logs float really well, because it's weight is reduced from losing the moisture it had when it was alive. New logs don't float and will sink because they're heavier than the water they displace.

Again there's no "natural buoyancy of an object". Buoyancy is a force from water that acts against the object due to the pressure lower in the column.

Also just because it can pierce through 10 cm of iron doesn't mean it can pierce through thicker thing without getting stuck (which would leave it an easy target)

Look at how long 10cm is, and imagine that space filled with solid iron. Are you really going to tell me, that something that can blow a hole through that, is going to be stopped by dry logs?

A 6lbs cannon ball is slightly smaller than 10cm in diameter, is made of iron, and can blow through dried logs or wooden fortifications with ease.

I mean, that's the party the buff dude last chapter mentioned.

 

[WhimsiCat]

You're not understanding the principle. Any object that displaces more water than it weighs will float due to buoyant forces. A brick of metal won't float but a sheet of metal of the same weight will.

And you're missing the point that a hole in the boat = water get in = no longer displaced = sunk. Raft wouldn't suffer to the same degree from similar sized hole in a log.

Except these are fish, not fucking cannonballs.
We don't even know if the hole they make is from stabbing/slicing with the horn or from just biting open a hole.

Also, it's more like having 2m long spear and not being able to stab through 4m thick wall of paper. Yes you can stab into it, but you don't have the length to go through completely.

And you're missing the point that a hole in the boat = water get in = no longer displaced = sunk. Raft wouldn't suffer to the same degree from similar sized hole in a log.

A raft and a boat with same displacements and having the same sized hole are going to sink at the same rate. It has nothing to do with any properties or design of a raft versus a boat.

Here's another point that's been ignored, water can just wash over onto the raft, much more easier than a boat and cause it to sink.

I don't understand why you're so hung up on "raft floats better than boats".

Except these are fish, not fucking cannonballs.
We don't even know if the hole they make is from stabbing/slicing with the horn or from just biting open a hole.

So a horn that can stab and slice through 10cm of iron is somehow going to get stopped by logs? Or in the case a raft of logs tied together by string?

Biting makes it worse, if the iron she's talking about is lower quality cast iron, that would imply the jaws of the boat killer have such massive crushing force to do so. And if the fish made the holes through biting, that makes the thickness of a log resisiting damage irrelevant.

Also, it's more like having 2m long spear and not being able to stab through 4m thick wall of paper. Yes you can stab into it, but you don't have the length to go through completely.

It's not about the length, it's the force and toughness factor of one material over another.

A 5.56 can penetrate far deeper than it's own length depending on what it hits.

I guarantee you if you take a 1m "spear" and accelerate it to 1000m/s it will go through 4m of paper like nothing.

In this case, the monster has over 900 strength rating, the Metal Lizard from before has 1200 strength.

A decently strong adventurer has 30 so strength. Do the math yourself.

You just come off as obsessing over logs being stronger than iron.

A raft and a boat with same displacements and having the same sized hole are going to sink at the same rate. It has nothing to do with any properties or design of a raft versus a boat.

The raft in image is floating 'flat', how the fuck would it be taking in water compare to boat if there's a hole? Do water in your imagination just somehow float above the raft and not spill off?

More like I don't understand why YOU are ignoring that issue.

Or are you somehow comparing other kind of raft and not the one actually shown?

Here's another point that's been ignored, water can just wash over onto the raft, much more easier than a boat and cause it to sink.

Again, how would a log raft 'hold' water above its flat surface to increase its weight?

You just come off as obsessing over logs being stronger than iron.

No, you're just being an idiot who misunderstood my words and somehow keep going with your own projection.

I never said log is stronger than iron, I'm just saying they're using the thickness of a log so that a single (or a few) hit from the fish doesn't immediately sink the raft.

You realize waves exist right?

Water is literally comming up over the sides and front here.

More like I don't understand why YOU are ignoring that issue.

I haven't ignored any issue, I assumed you understood what basic lake and sea conditions were like. That was my fault for having that expectation.

 

[SunSun]

Again, how would a log raft 'hold' water above its flat surface to increase its weight?

Because water has surface tension, there's also adhesion with surfaces however slight, and the weight of the water is still going to push down on the raft for the moments of time it's in contact with the surface before it flows off.
Each time any wave pushes unto the raft and then down to flow off, it causes the raft to lose more and more stabilization, and losing its sea worthiness.

No, you're just being an idiot who misunderstood my words and somehow keep going with your own projection.

I never said log is stronger than iron, I'm just saying they're using the thickness of a log so that a single (or a few) hit from the fish doesn't immediately sink the raft.

Except the characters said the complete opposite.

Kaede knows they're screwed, and they themselves know they'll be screwed and will be using magic instead.

So again it just comes off as you for some reason thinking that thick log better than 10cm of iron.

If you had instead said the characters were using a raft instead of a boat cause they can't rent a boat, that'd been more reasonable.

Instead you tried to justify something the characters themselves knew would not work.
