Depends on whether the boat was masthead or fractional. If masthead and the rig was not supported by the runners and checks by all means blow them so that the main can go over. If fractional, with in line spreaders, get the new runner on first even if the boat is pressed in the water by the main. Biggest cause of broaches on the 1ton in heavy air jibes was IOR shape but rather the failure to get the new runner on and old off in a timely fashion.And what about the runners?
...and if the wipeout is to leeward make sure someone blows the foreguy right before the tip of the pole goes in the water. That's important.
