Many people do not think much of the ship travel or the associated combat but I actually love it and am looking forward to more of it in the new game if set in Viking Age.
Even if it is probably way too late to suggest changes at this point I would like to see the controls of the ship handled more like they did in the sparse moments of naval settings seen in AC Origins rather than the Adrestia in Odyssey.
Although the Adrestia was obviously the more fleshed out experience the absolutely biggest immersion breaking factor was that it moved way, way too fast even at the slowest speed, as if the rowers below were jacked up demigods themselves (those guys are the real hero's).
Anyway I liked the joystick speed control in Origins ship control much better, where as with the character land movement you could move at a very slow pace if you wished to. Many will find this a trifling thing but it always bugged me through my hundreds of hours of Odyssey.
Thanks, and stay healthy people.
