I recently installed a lazy jack system on hull #273, now I can douse the main from the cockpit.
Here’s how it’s set up
2 small cheek blocks installed on either side of the mast about 6 feet above the spreaders. 4 small eye straps installed on either side of the boom 18 inches and 84 inches back from the goose neck
2 3 inch plastic cleats installed on either side of the mast about 24 inches above the deck to tie off the line, leave plenty of extra line here so you can stow the system against the mast when not in use.
I think I used about 100 feet of line
The line(s) coming down from the aft side of the cheek block have a small swivel  block attached to the end, then run a separate line from the first eye strap thru the block down to the second eye strap, this triangle effect you have created can be adjusted to suit.

A word about the line: I first used ¼ nylon but It had much to much stretch so I went to 1/4 braided Dacron.

There is some thinking you need to modify your sail cover for the system, not so, when the sail is down, gasket the sail as normal and release enough line from the cleat on the mast and stow the lazy jacks against the mast ,then put your cover on.

The boat gear catalogs list the kits at over $200.00 I think I have about $80.00 invested.
To better visualize this system look in the West Marine or Defender catalogs

Davysmartg,  read the next to last paragraph above.  Works well, I'll be doing the same. 

I would do that as well, however, I need to stow the lines in order to put up my cockpit awning

Herby,

Your right about having to remove the lazy jack for the Bimini over the cockpit.  One thing to consider when installing lazy Jacks, if you also have a Bimini.  Make sure you can reach the blocks coming down from the mast so you can re-install the lazy Jack lines.
