We had a nice stop over in Cherbourg, moored close to the "Cité de la mer", a fascinating museum where the visit of the Redoutable submarine is really worth.
We stayed in Cherbourg until 22 August, and after careful planning using Windy and the maps of currents by hours in the area, we decided to leave at 1:00 at night, with WSW winds 14-16 m/s, to benefit from the currents pushing us out of the English Channel along the French coast where they are strongest, then tack towards SSW in order to make it to Brest. But it did not work this way...
