Help with a quest: All hands on deck

[Sunbro]

In this quest the guy Marceno wants you to find a chest before the captain comes back. You find it, kill some guys and then you can take it, open it, or leave it be. Does anyone know how to open this chest?? One would think it was mechanics or might or a prybar....nothing has worked for me. The guide says you can take it and open it but I don't see how you could do that either.

 

 

Thanks

I just did it today, and it said to me that all I needed was Mechanics 4.

 

When I click on the chest, I have this "old paper story" (like when you Awaken at the beginning of the game). There, you can pick up the chest or open it (with mechanics)
