Two additional thoughts on the mainsail issue:
1) Be sure your vang tension is eased before hoisting.
2) Leave some slack in the mainsheet -- yes, it will cause the boom to jump around and the sail to slat a bit, but relieving these two pressure points greatly eases hoisting.
I agree with previous posts about Battcars and using a dry lubricant like McLube. Using this system on JUNO, which is a 40 and thus has an even bigger, heavier main, I am able to hoist the sail from the cockpit by hand except for the last few feet when I go to a winch.
