At its very widest the channel is less than a mile across, so there is less than half a mile to go. Holy crap these things are slow, but apparently that would take less than ten minutes, less if aided by gale-force winds. Did ten minutes pass between "I can't handle this storm" and "oh shit I've killed us all"? Probably!
