Would love to hear an expert talk be about this more. It's an interesting idea, but seems like it would be limited in usefulness to small adjustments.

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

I stumbled on it when figuring out just how the hell tall ships docked and undocked without tugs. Turns out they did use tugs in the form of rowboats but they also extensively used shoreside rigging and warping.
Edit: and I should add, they very rarely actually docked in the first place because it was such a pain in the ass, so they used tenders instead mostly
This also bugs me in movies whenever someone is kicked off the boat, but they're given a small rowboat and some provisions. Like, that wasn't an extra boat. It serves a purpose on the ship, and everything that takes up space on a boat is precious. A "spare" rowboat could be the difference between life and a horrible death. It could be months before they find a port where they can buy a replacement rowboat.
I guess it would be valuable in shallow water, less useful in the deep ocean, and overall better than being stuck in one place!
Yeah me too. I tried searching around but it's hard to find something that's not sci-fi related about this topic. It might also be called "kledging" from what I read, but not sure if that's the exact same thing.
Have to admit, after reading the title I double checked the community for 'onion'!
"Prepare to travel by warp."
"Captain, that will set us back days!"
something-something dimensional anchor
Commencing the naval operation by tooting my Warp Whistle
Thank you Boatswain Underpants. Keep up the good work.
Pipe lay (etc) anchor barges do this today.
There are usually six to 8 anchor winches on the vessel. A tug comes to the barge, picks up the anchor and moves it out to some point while the winch unreels. Repeat for other anchors. Winch in to move the vessel.
This is used for precision movement/placement of the barge.
Many vessels use azipods and Dynamic Positioning System (DPS) these days.
But before DPS much of offshore infrastructure was placed by anchor barges.
Those vessels have truly advanced warp drives.
Depends on the quality of the dilithium crystals..
I’ve been kedging for hours and I still don’t think I’m close
Imagine actually moving like this. “Here little ship, take our anchor, we can move another 100 meters and only have to repeat a million times”
Sounds like a lot of work. I have no idea how heavy a ship's anchor is, but I imagine it would be hard to throw any significant distance.
How does one "throw" an anchor tho
Just have 26 STR and 9 DEX.
Try piercing but hole.
A very strong Scottish guy
simply put it into a canon.
Does one simply throw a boat anchor with a cannon??
We'll just use a howitzer to launch the ring into mount doom.
Hear me out
Trebuchet
I would definitely like to see a ship propel itself using a trebuchet and a windlass. Not enough to try building one, but still.
Doesn't this defy the laws of physics?
A trebuchet primarily transforms downward motion (of the counterweight) into forward motion, so it would actually work - the trebuchet doesn't push the ship back as much as it pushes its load forward. This is particularly so if your trebuchet has wheels and you have room on your ship to accommodate it rocking back and forth when firing.
Edit: Thinking about it this technique would work even with something that does impart equal backwards force on the ship when firing a projectile, because there is considerably more force involved in winching the ship towards the anchor than what is involved in actually moving the anchor. You aren't pulling against the inertia of a free floating anchor after all, you're pulling against the ground the anchor has hooked into.
Not only that, you're using the friction between the anchor and the seafloor, so even the recoil of a propulsive ballista will allow you to perform work.
Indeed, I just realised that point - the force of propelling the anchor is tiny compared to what you can exert on the ship once the anchor is hooked.
I've got a really wild idea: what if you change the shape of the anchor so that it's actually getting resistance against the water itself instead of having to hit the sea floor. You'll have to pull it out if the water once you're done moving it and then drop it in again. Maybe put it on the end of a big stick. I'm thinking about calling this type of anchor an "oar."
I bet you could get a bunch of money for a CGI prototype of your new green cargo ship.
i would presume that would be what one is to do. It seems the logical solution here.
If you do it in water it's not as heavy.
The rope attached to the anchor chain is called the "warp". Hence warping.
But where did they get the dilithium?
Two lithium rocks
I'm a little sad that I didn't get to see the HMS Enterprise with warp nacelles.
Wait till he hears about looms!
Hey warp and weft is why I mentioned threading a needle across the sea.
