If you do 100km more you can BBQ with me

Evreux the place were I live is at about 1 hour drive.
If you are coming with a boat it will be easier to plan a route from port to port following the coast like this :
from North to South :
Fécamps,Etretat ,Le Havre
Honfleur : a pretty nice little town
Deauville-Trouville : less pretty but pretty enough with some Casino (in September there is the "Festival du Film américain"/american film festival)
Cabourg/Houlgate : see Honfleur

Sword,Juno,Gold,Omaha ,Utah beach
Bayeux
Alternatively you can rent a car in the Havre and make the trip by the road.
Or I can drive you in the part not accessibles with a boat.
Lastly Le Havre (like Caen) is not a pretty place the town was completly destroyed during WWII
