We describe the salient features of precise predictions for the processes e+ e- -> WW -> 4f(gamma) as obtained with the Monte Carlo generator RacoonWW, including the complete O(alpha) electroweak radiative corrections in the double-pole approximation. Numerical results for some distributions are given at the typical linear-collider energy \sqrt{s}=500 GeV. Moreover, we study the impact of the non-universal electroweak corrections by comparing with results of an improved Born approximation.
