I race on extremely shifty/gusty/heavy air lake. We often loose control of our boat downwind. What is the safest/depowered wind angle and rig set up downwind when flying a chute?
My guess:
Broad reach
Pole on lower ring (despite what tuning guides advise)
Pole end down, tack lower than clew
Pole 1 ft forward of perpendicular to wind
Downhaul tight
Both twings to deck
Foot of spinnaker 6 inches off headstay
Maxed out: outhaul, cunningham, backstay
Vang tight, upper batten parallel to boom
Main back 6 inches or so off the spreader
Crew weight back, balanced and ready to move to high side
1 crew member always holding boom and ready to bust loose the vang
Trimmer ready to release spinnaker sheet (broach only)
Driver ready to release main sheet
Spinnaker halyard running in water so it won’t tangle in an emergency douse

Are you running downhill or reaching?
What wind speed are you reaching in?
What course are you sailing , windward leeward or a tri-angle ?
We race windward leewards courses in a gulf with big sea's , the bigger the better downhill and our best speed in 30 knots of breeze is 16 to 18 knots.
thanks

If your goal is to prevent wipeouts downwind with the chute up the prioritized list would look like this:
Crew weight back
Crew weight back
Crew weight back
Crew weight back bowman and twinger on the stern pulpit. middleman next to or behind the skipper. trimmer (in cockpit) is the furthest fwd.
Pole on lower ring ..... time spent thinking or doing this means you don't have the crew weight aft. whatever it is, is fine
Pole end down, tack lower than clew ...... ..... time spent thinking or doing this means you don't have the crew weight aft. whatever it is, is fine
Pole 1 ft forward of perpendicular to wind .......... time spent thinking or doing this means you don't have the crew weight aft.
Downhaul tight ......... time spent thinking or doing this means you don't have the crew weight aft. whatever it is, is fine
Both twings to deck ...good idea. but either do it before the set or do it after everyone is aft
Foot of spinnaker 6 inches off headstay .....OK but do it from the transom
Maxed out: outhaul, cunningham, backstay ..ok, but ..... time spent thinking or doing this means you don't have the crew weight aft.
Vang tight, upper batten parallel to boom ... hmmm flat main, but twisted off at top doesn't always mean parrallel to the boom.
Main back 6 inches or so off the spreader
1 crew member always holding boom and ready to bust loose the vang. here we go again. vang line long enough to get back to the cockpit. no one can reach the boom if the weight is in the back of the boat
Trimmer ready to release spinnaker sheet (broach only)
Driver ready to release main sheet... this should be a lot more dynamic than just being "ready" to release.
Spinnaker halyard running in water so it won’t tangle in an emergency douse ... time spent doing this distracts from keeping from wiping out.
If the skipper fits the typical mode where he (she) is the one worrying about all the above details and is busy micromanaging the rest of the crew halfway down the leg to make sure the jib cunningham is perfectly tensioned ..... then there is a basic problem....... The skipper needs to stay 100% focused on anticipating the helm load up (precursor to the wipeout)
keep the boat under the mast
