I keep forgetting about it - but I had a pocket sewn into the bottom of my F18 trampoline to house a drag chute (aka "drift sock") that I could clip to the dolphin striker, run a line through another carabiner freshly clipped to the forestay, and then tossed in the water. The idea is that it slows the boat moving through the water and keeps the bows pointed into the wind while capsized and immediately after righting. You should be able to reel it back in from the line clipped to the dolphin striker once you have everything sorted. If you have to get undeway quickly (to retrieve a sailor), just leave the drift sock pulled up the forestay bridle and deal with it later. This could come in useful if one of us gets separated from the boat. I keep forgetting to buy the drift sock to try it out.
