Ok, you are looking at Andrew's drawing. No matter what you are going to have a lot of slack on the floor, but an organised one.
I am using my front winch as a turning block, simply running the sheet on the outside of it, instead of the turning block (sheave) mounted to the gunwale. If you are using sheaves it is permanent, (the sheet must be reeved through the sheaves) while the way l run my sheet, is temporary. It is very much the way Phoenix drew it but l do it on the rear winches. If you look at the foto you can see what l mean, while l am sitting on the stb ppit seat where l normally steer the boat from while l run the auto pilot a lot, as well.

You also can see the double jib traveller sheaves on the jib traveller track. The front one to be adjusted while the rear one left mostly permanent. The jib sheet does not touch the sides even when l use the front winch.
Imagine:
I am on stb tack, sitting where the fellow sits on the pic.
The sheet comes back from the jib traveller on the port side, runs on the port side of the front winch, (the wrong way if you want to use the winch! but it's function now is of a turning block) than crosses over to the stb side rear winch (mexican hat on pic) and this is the winch on the front of me sitting there steering. I can adjust the jib easily, winch it or let it out.
In case of tacking or gybing l can pre load the future working winch, run the line outside of the 'turning block winch', front winch on stb, swap the handle over, move to the lee side, release the working winch with plenty of time to pull in the slack on the working side, sit down and crank while the tiller is between my legs or close, under control if l do not use the auto pilot which l do a lot. Tacking with the ap. is a blessing in disguise!
If you are thinking about the main sail while tacking or gybing, l bring it in and think of it as a self tacking sail without paying much attention to it until l sorted the jib, then l adjust it.
The main sheet is in my hand at all times for well known reasons particularly in blowy bad gusty weather.
If for some reason l want to sit on the leeward side, (weather, spray, traffic, whatever) l run the jib sheet back to the rear winch, passing the front winch on the port side keeping it away from the coaming, without crossing over to the high side.
As l wrote earlier it is m y setup. It is tailored to the boat and my personal preferences.
If you decide following the idea, blindly copying it, then most probably it won't work.
Taylor it to your boat and your physic and you are never going to look back after you worked it out.
I strongly recommend an auto pilot like ST 2000 or similar. I warn you against contemplating the ST 1000 model despite it's price advantage as it's drive is not reliable! When the boat show is on, there is a 15% discount on Sat and Sun at
