Difficulties getting it up (mainsail halyard led aft, high friction)

Interesting.

Work back pulling at each turning block, organiser, etc in order and feel where the resistance is coming from?
It's not obvious. I think it's multiple factors playing together. The only thing I could clearly identify is the block that's bolted onto the mast and that has really high friction because the sheet wasn't runing clearly and straved the sides. But now, with another block, it's only 10% better. There is still a lot of friction somewhere.

And fyi I miscalled it a clam cleat all the time but I meant a clutch.

Also somethings up with the forum, I can't multiquote and the timestamps only say "latertoday". I guess they're working on something and thats why I can't upload pics.
 
You are opening the clutch we assume. But itks quite possible that it's adding to the friction. Rope oversize for it? Gone furry? Has something gone a bit wring with the mechanism, or is the internal cam dragging cos it’s just a bit stuck? Mine are often like that in the spring, we give them a good spray of WD or equivalent, and work them vigorously, poking the cam up and down with a screwdriver. That, new sheaves, decent roller bearing ones like those Ronstan things, most makes do similar, and you’ll have it sorted.

Hm i haven't cleaned or checked the cleats this thorougjly. I'll do it when I am back

The slightest bit of rope rubbing on the block will cause problems. Worth spending time aligning the block. Could use some nylon blocks under the pulley or even bits of wood to work out what's required and then construct in a better material.
 
For reference: Directly at the mast I can pull on the halyard coming out of the mast and it's really easy to raise it and it falls down like a sack of potatoes - meaning with speed and kawumm. Good stuff. That's how I eliminated any internal issues or issues with the track. I can raise the main to the very top with hand over hand from a deck seating position.
I think in a way that you have answered your own problem here. I have always wondered why the need to add extra complexity extra gear and extra friction by arranging a mainsail hoist from anywhere apart from at the foot of the mast. So why not rearrange it to hoist the main from the foot of the mast??
Yes I know some folk like everything to be managed from the cockpit citing reasons like safety or convenience but personally I would dispute these.
When I purchased my current boat (and the one before if memory serves me right) the main was set to be hoisted from the cockpit and one of my first jobs to set the boat up properly was to rearrange the hoist to be at the foot of the mast. I have never looked back and never regretted that choice.

Well, I am one of those people. I want to handle everything from the cockpit for safety and convenience.

I sail solo and don't want to go overboard, even if I am clipped in. It's just something I'd rather avoid. And I also don't wabt to slip around, bang agaibst everything and maybe fall on a corner in rough conditions just because I wabt to put a reef in. Been there, done that. Better to do ut from the cockpit. Just got to make it work.
