In fact so good that if you have to make an emergency landing in wooded terrain with little open ground but many lakes (such as you commonly find in Scandinavia), you should ditch the aircraft in a lake rather than take it down into the trees.
I've heard the opposite from an instructor in BC - "if he fan stops we're going for the trees - people do strange things in cold water when their brains stop working, like trying to swim into the back of the plane".
