To deploy a parawing is to open it from stashed so the wind re-inflates the canopy and you can ride powered again, the reverse of a stash. The rider pulls the bundle from the belt, unwraps the lines, holds the bar in front with the wing trailing downwind at the surface, and lets airflow fill the leading edge gradually instead of yanking it overhead. Also called redeploying or unstashing when done mid-session on the water.
Stash, glide, deploy, repeat: that loop is the sport (glossary), and the deploy is the half that gets you powered again. It is also decided before it starts. How cleanly you captured the lines during the stash is what lets the canopy open; rush the wrap and it tangles the moment the wing tries to inflate.
The sequence itself is short. Bundle out of the belt. Lines off the bar. Wing trailing downwind at the surface, then feed tension out gradually and let the airflow do the inflating. Single-skin canopies pop open fastest; double-skin and reflex designs open cleanly too, but only once you have them sitting right relative to the wind. Short linesets work in your favor here: most parawings run roughly 2–4 m lines, so twists resolve quickly while you float. The technique breakdowns at WING DAILY and Green Hat Kiteboarding cover the details.
You will blow some. Forum riders report about 50–75% clean redeploys early on. When lines wrap, come off foil and sort them while floating; hauling on a tangled lineset inflates nothing. Step by step, the sequence is in redeploying on water.
A downed parawing with lines under wave load turns into a dragnet, and that is where line injuries happen. Sort it outside the impact zone, every time. If a deploy does fail in swell, recovering it is a skill of its own; see swell tangle recovery and the safety episodes of the Flysurfer POW Academy. Brand touches earn their keep under pressure: most parawings mark the leading-edge center panel, and color-coded bridles (Ozone, F-One, Ensis) exist to speed up orientation while you deploy.
