A guy at Nacra NAs this year from Canada showed up 20 minutes before everyone was heading out on the water and had his F18 rigged in 15 minutes. He had came straight from another regatta a few hours away and had almost everything set to go... spinpole on, spin in the snuffer, rigging on, boom and boards on the tramp.
Not sure I would practice this method but it seemed to work fine for him.
