On the 5.2 with the jib: tack while keeping the jib sheeted. Once it fills in on the wrong side, against the mast, release the traveler to midpoint and a bit of the main, and push the tiller over as if wanting to tack again. The boat will park.

On the 5.2 without the jib: Stop the boat by pointing high and over sheeting the main. When the boat starts to back up use the ruder to choose the tack you want to park into, keep them at that position and release the traveler completely and a bit of the main.

In both case the boat is going to enter into an oscillating mode: forward and up until the main stops getting traction, then backward until the main gets some power again.

I don't bother with the downhaul on the 5.2, it's not powerful enough to make a difference.
