Flipping your braid on your reel.....
 

I sure alot of guys just replace it with new.
For me I choose to flip it, what was simi old becomes new again. Plus I have a sliced knot in my line and I want it closer to the arbor. I hate feeling knots go through my guides period. This technique works for small bass reels.
When you don't want to transfer to another empty reel.
If you have alot of the same setups you could just play musical reels, and swap.
One bass reel flipping line I use a pool noodle and a piece of tape to hold your spot so if your arm get tired you can take a break just spot tape it.
Take your time and just slowly wrap around the pool noodle tightly like a spring. The bigger the line capacity the tighter the spring warp just estimate it.
Once you have all your line safely taped to the pool noodle the hard part is done. Take a break or go back to it, swap ends and tie your new arbor and just start winding with tension and letting the pool noodle flopping on the floor it will spin and unwinding it self until you come to the taped end. If you know a better way I would like to hear. I do not know how you would flip line that's to much for a pool noodle. Except reel to reel or reel to empty spool.

Also you could.....
 

Just transfer to another pool noodle Just tape and leave a 5ft gap or even 10ft what ever works for you, between pool noodles ect ect .and so on
Also if you want to wash the salt and grime out spray it with a mild dish soap and flush with clean water and hang it up to dry
The ocean has alot of floating oil too I used to wash it off my dad's and my boat.

Using multiple noodles may not work
 

Because of The twisting I never done it
But you would just need to experiment.

I call it end for ending. We would do it on ships with the mooring cables. I end for end braid to get more mileage out of it. I just use some of my older rockcod reels to stow the line. Wind it onto an old 9/0 reel, then on to a 6/0, then back onto the original reel it was on and Walla, the bottom braid line is now the top, and the dried out topline is now at the bottom of the spool.:reel:

Let's see 👀.....
 

Top 1 becomes bottom 1. Bottom 1 becomes top2 .top 2 becomes bottom 2 and back on reel
By gorge your right I didn't think that far ahead
You just need 3 reels that's alot easier I can't think that far ahead thanks:cheers1:

I new there had to be an
 

Easier way:reel:

But the noodle works fine....
 

For the guy that doesn't have extra big reels with the space 😎

I usually use a couple of empty line spools and an electric screw driver to juggle the line. Empty the reel on one spool, empty that on the other and then back on the reel. works fairly well.

Works Great
 

Works great. I've been using that method for years...so simple:cheers1:

Most definitely....
 

The best way :cheers1:
I've changed my guitar stings that way

Yep.....
 

The third time ⏲️ is the charm. I must have been really bored 😴
