My guess is that NAF 11 first went to Morocco for the inauguration of 'Tarik Ben Ziyad', the Frégate Multi-Mission Marocain (FMMM), built by Damen shipyards Vlissingen, with VADM M. Borsboom (CZSK).
And afterward it continued to OUAZ, as the Admiral is to spent X-mas together with the NL forces there.
