Comment on why do reverse thrusters work on an airplane, but a fan on a sailboat doesn't work?

  The reverse thrusters redirect the air coming out in the opposite direction, so it is like turning the fan in the opposite direction.

  A sail catches the air to pull the boat along and some of it bleeds off, but it does not direct any air backwards to propel the ship forward.
