Different approaches to dousing. Depends on one- or number of (capable) crew, seaway, whether it's night or you're doing it just in the day, who's steering (or whether the autopilot is working), and WIND.
The basic principle (as JustSomeGuy suggests) is to de-pressure the sail. Blanketing it is the best general way, in my opinion. AS SOON as you de-pressurize the sail, you want to get the sock down and secured enough so that it won't "re-inflate". The ATN is a GREAT sock system. Usually the sock is cut so that you don't get it all the way down -- i.e., there is enough exposed of the tack to allow you to connect some of it forward and have a bit of the clew to attach.
Some spinnaker take-downs (including symmetric chutes) involve letting the "tack" flutter out while pulling the chute aboard. In sporty or heavy winds, or when you're setting a jib and pulling the chute in after rounding a mark, it's the preferred method.
I don't do when I'm putting away our asymmetric chute while alone or with limited crew. I don't pull-out the jib until the chute is put in the bag. In my case, I ease the tack line (and allow the sprit pole of J/Boat) to come in to where your Beneteau would have it's tack) as soon as I blanket the main. Then I ease the sheet enough to make sure the sail is depowered. THEN THE SOCK COMES DOWN. After the sock is down, I then release or ease the tack line. The chute-in-sock is lowered BEHIND the main and bagged, with the wind far enough aft that it doesn't fight you.
Of course, if you are out of room and dropping the chute with some decent crew (and someone at the helm who understands what's going on), then you can do some things somewhat differently. Before you try those things, I'd get comfortable with less rigorous approach.
The key to remember, that chute is a lot more powerful if the wind fills it than you are. You aren't going to simply muscle it down on a 40' sailboat. DE-PRESSURIZE (de-power) the chute, Sock-it, drop it behind the main as you fold-it into the bag.
