If the wind is making up, the only really safe way to douse the main is with the boat headed directly into the wind. If you try to do it off the wind the sail will catch the wind and you run the risk of getting it caught on the
rigging.
If a batten gets stuck behind a spreader, you could have a difficult situation to deal with. If there are any little barbs on your shrouds, you run the risk of rips and tears.
If you keep the boat heading directly into the wind, and if you sheet the boom in dead center, the sail will not flap excessively. The noise and turbulence come when the boat is off the wind slightly or the boom is allowed to flop around.
