The reefed portion of the sail is affixed to the boom these days with a "slab" or "jiffy" reefing system. You now have one or two lines that run along or in the boom, through blocks, up through grommets in the sail at its after-most and fore-most ends, back down the other side of the sail, and then affixed to a strong point. One pull on the reefing line(s), and the entire sail is brought down to the boom in a big slab. Affixing the end of the reefing line to a cleat on the boom then completes the action. If you have reefing points, you can then tie them off, neatening the look of the sail. You then rehoist the halyard taut. Reefing done.
Here's a link to a slab reefing diagram:
Reefing the Mainsail - How to Reef the Mainsail - Slab Reefing for the Mainsail
I have never seen reefing lines that weren't cockpit accessable, and if your mainsail halyard winch is on the coach roof or if the lines are lead back to the cockpit, then you don't have to leave the cockpit to reef. On my boat, I have two reefing lines, both accessable from the cockpit, but my halyard winch is on the mast, so I do have to leave the cockpit to reef. Consequently, I reef before I leave the dock whenever possible. One of these days, I will change over to a single line system like the drawing. One of these days....

On my boat I have a two line reefing system (one for the tack and one for the boom end). Both are led back through clutches to the winches on the coach roof (one on each side).
Each coach roof winch can be used on several lines by help of the clutches.

Thanks to all for the helpful information. A follow up question. On a boat set up for single handed sailing how does one secure the mainsail to the boom when reefing the sail. Do you have to leave the cockpit and to secure the main to the boom or can a winch handle that?

The winches located on the cockpit coamings are used to control the jib or genny sheets. When the boat has a big main sail, sometimes you need a separate winch to control that sheet too. I can't recall if I have ever seen one on a boat the size that you describe except for an all-out racing machine. This winch is often located near the aft end of the cockpit.

On a C&C 34 I used to race on, starting from the stern:
2 primaries for trimming the genoa
2 for trimming the spinnaker sheets/guys
one on the coachroof, port side to trim the mainsheet
one on the coachroof starboard side to manage the pole uphaul
one just aft of the mast for the main halyard
one just to starboard of mast for the jib and spin halyards starboard side
one just to port of the mast for the jib and spin halyards port side
one just forward and to starboard of the mast for the babystay
All that to say, it really depends on how the boat is set up. 10 winches on a 34' boat is old-school. On my previous Jeanneau 35, I only had 4 as all lines were led aft to the cockpit. The primaries by the cockpit would be used to trim Genoa sheets and spinnaker guys. The coachroof winches would be used for all halyards and trimming spinnaker sheets.

|Irunbird||In a nutshell- any winch that is available and can accept a line coming through either a block or clutch can be used for trimming headsails, mainsail or reefing- the caveat being that it must be run fair to the winch; the closer the better to a point... I'm assuming the halyards on your boat will run down to the mast base, through a block on the cabin top, through a clutch, then to a winch directly inline with the clutch. Some halyard winches and clutches are right on the mast, though... It just depends on your configuration.|

|Barquito||Any line you need more mechanical advantage. Some lines have block and tackle (vang, main sheet, cunningham), others will need a winch. Halyards, reefing lines, jib and spin sheets.|

Purpose of Winches
Would someone please describe the purpose of the various winches on a 34-36 ft. sloop. I know that one each would be for raising/lowering the main and the jib. But what about the others. I suspect that there is a winch for reefing the main but am not sure. Thanks.
