I feel the need to explain Artyom's thought process at the moment. From what he has seen of Ade, she looks like a refugee who has no business going into the ruined remains of two kingdoms that have been overrun with monsters from the abyss and thus actually taking a person like that with them is a stupid idea, not just because its endangering her life, but most likely theirs as well. 

However, seeing that fire in her spirit has made him consider that all she really needs is some time and training to make up for the above liability... the former of which the team has in limited supply unless... Hmm. Just thought of something that Artyom might suggest. 

If the party set sail the moment the ship was ready to go, how long would it take to reach out target destination?
