Careening.
Oftentimes, pirates do not have access to dry docks without a hefty bribe to the people of the docks to not report them to Marines, as well during long voyages between islands, especially in the Grand Line, where one could go long bouts without seeing a dock.
This meant that Pirates had to rely on finding non- magnetic or rogue islands while sailing to clean their ships.
The Process itself was done by attaching tackle rope to parts of the ship, from the mast to strong points along it to then be pulled onto the island while tipping on one side to clean the hull.
After that, it's then floated back out to the sea and turned to the other side.
"A Clean hull means an extra knot or two in speed." Kirk said as him, Leroy, Kále, and Noir rowed their way to the small sandbar. Pulling the tackle behind them and up onto the beach.
"Try not to put too much strength in it alright you three? I know even one of you could pull it all up onto the beach yourself, but we don't want to but strain on one place."
"Got it." Noir started
"Aight." Leroy added
"Whatever" Kále finished
With rope in hand, and Jeanne looking from the crows nest as Dezzi and Raven watched from the railing. While the other four worked their way to the sand bar, they made sure to move any loose objects into boxes and into storage just as they had for their descent from Skyderia
"Alright, on three! One, two, three!" Kirk called as the trio were all in position, he was making sure that the ship was on course while the three pulled.
With ease, the three pulled the tackle, moving their hands as they did. Waves lapping up against the side of the dark brown wood, white peaks of sea spraying against it.
It took only a dozen minutes for the ship to gently be pulled onto the shore, wood creaking as the sand was scrapped against the bottom.
"Root Stalk!" Raven lifted her hands, and the Blossom fruit flourished multitudes hands that came from others and other coming from more. Serving as pillars to hold against the weight of the ship leaning on them, pushing against the back so that the other side was exposed.
Deep green algae like vines clung to the bottom of the ship, the wood soaked making the brown wood look black, a crust forming against it like a gradient of green and black before fading back to the brown where the wood wasn't constantly submerged.
Then there were the Barnacles, the razor sharp cones like miniature volcanoes.
"Damn. The palm's so dirty I can't even see the Keel." Leroy said, pulling a hand to block the sun, the long shadow of the looming ship in front of him.
"Best get to work then!" Jeanne reappeared from her steam, carrying many scrapers.
"It'd be perfect for Keelhauling." Raven said with a slight smirk. Dezzi next to her, the Doctor
giving a playful sinister grin "Yeah it would be…"
"Hahahah! I could only imaging how much that'd suck." Leroy said going up and feeling the sharp edge.
"Luckily we have you Raven, that Devil Fruit of yours will come in handy!" Noir unbuttoned his sleeves and rolled them around his elbows.
Typically. It'd take weeks to effectively clean the under of a ship, Scraping, pulling, resting moving.
But with the efficiency of having literal dozens and dozens of hands Scraping at single spot instead of having an entire body to block spots, the crews cleaning didn't take very long at all.
"Woah…Oh Fuck…" Leroy suddenly recoiled after an hour of working. Sitting on the hands of Raven as a seat. He'd worked his way back down to the middle of the bottom where the keel was. Scraping away thick algae and barnacle crust
Only for it to reveal deep cracks into the wood. Not just hair line fractures, but rended pieces of wood that looked to have been entirely snapped in two. The entire keel was almost in to separate pieces.
"Heheh, what's- what's wrong Leroy?" Jeanne said her chuckles from talking with the rest was suddenly cut short, and abruptly. Eyes widening
"Oh-"
It wasn't long until the entire crew was sat looking at the fracture. It was deep enough that the bottom blank of the bilge could be felt.
"When did this happen?" Raven pondered
"I-I don't know. It could've happened at, literally any point. For all we know, one of the Marines chain shots could've done it."
"But- That was months ago!" Kirk said in surprise
"Even if it was, as recent as us coming back down, which was a pretty rough landing. It should've caused us issues by now…"
Leroys brow pinched as he looked.
"Well." Kále began. "Do any of you have a solution?" The Swordsman wasn't worried.
"The only thing we really can do is patch it up." The Captain added.
"L-Leroy…" Jeanne began "You, know that a broken Keel is like a horse with a broken leg…Right?" Her face was filled with worry as she gazed at her Captain.
"I know. But we'll fix her. Even its temporary. We'll fix her." He gave a grin. "Water 9's the best in the world right? That means they'd be able to replace the keel."
"If it'd it be like replacing someone's spine. Just, cut there and there." He said pointing at the stern and then to the palm figure head. Put the new piece back and- She'd be ready to go I'd think!"
"Hmm…Maybe. I've seen ships sink from less. It's a miracle that she's carried us this far" Kirk said with a pout
