Bermuda here are a few photos of a boat that has ALL the lines coming to the cockpit.
This boat has a slightly complicated arrangment but if you look carefully you will understand it.
2 halyards for the main
2 halyards for the spi
2 halyards for the genoa
1 boom jack (no vang)
1 extra Cuningham (for emergency)
2 Roler lines (continuous line so you have 2 lines)
2 spi uphauls
2 spi pole lines
2 genoa track lines
2 genoa sheets
2 main sail sheets
1 backstay at the rear
2 Barber haulers for the spi
The boat in the photos has a rather expensive arrangment due to the nature of the blocks and gear used, but it serves the purpose of giving you an idea of what can be done.
you will need several blocks at the mast, don't use the ones in the photo they're expensive, use regular blocks with springs to keep them upright.
You may attach them to the mast collar ot to the cabin top with respective becking plates underneath. Sometimes, if you have a keel stepped mast you will require the installation of a rod, inside the cabin, to prevent the cabin from "curling" up caused by tension in the mast blocks. You will also need organizers. They are the black "rulers" you see laying down on the cabin top to redirect the lines aft
Mast foot blocks and organizers
You will need clutches as above and cam cleats to hold and secure the lines
The photo above shows that in this case there are two sets of deck organizers to distribute load better
Here above a front view of the arrangment
And a rear view
If you have more questions I can draw a "map" of the lines for you.
