Why this is we don't know - perhaps there were too many crazed boaters departing Roche Harbor so they decided to take a different route? Maybe the Department of Homeland Security wanted something too look at with their new fancy remote camera array at Turn Point? Maybe the captain wanted to wave to his girlfriend on shore (it has happened before)?
Who knows - perhaps someone could fill us in?
