I'd get a braked trailer.
Horrible feeling when the trailer jack knifes the rig.
As far as I remember (as in the link above) no trailer in Germany over 750kg was allowed to be unbraked. Only The heaviest/biggest cars would have a 750kg rating. I would think the Forester would be border line. You might even find info in the vehicle manual.
