Replication Update WITHOUT Possession

For simplicity sake I’ve recreated my problem using the 3rd person starter content, all ship movement is done using the starter code. Replication is working seamlessly (ish…) while the Player Controllers are in control of the objects. But this particular case requires the players to ‘Possess’ both the ships and the cannons at different times, while in possession of the ship the replication works perfectly - However if the ship is in motion and the player exits the ‘driver seat’ the ship will continue to move on the client side until another player Possess’ the ship. At which point it will snap back into place.

Ship sliding away once unpossessed but remaining in place on the server side.

Is there a simple way to enable replication on none possessed actors? Or should my actors always be possessed by a ghost/AI to ensure they are relevant for replication.

Thanks in advance for your time
