Re: DDW and bailing out
For us due to solent rig to gybe the genny you need to roll it up then let it out on the new side. Get more speed and much less drama going wind and wing. Can keep the set up for 15+ degrees either side of DDW with just little tweaks. Have line attached to end of boom on both sides lead forward to bow and then back to cockpit. Controlled with clutch at side of cockpit. Preventor line has break in middle with quick release. Takes a second to set up and switch from side to side. Use it all the time and still have a head on my shoulders.
90 degree wind shifts must be hard to deal with. Fortunately don't have that problem.
