The Witch is long gone, as she doesn't block or kill with poison. Three conspirators have already been killed. All that's left is the boatswain!
Who died now? Based on the description, it seems like the Navigator, but somehow it doesn't seem like him.
Alive: The ship's Captain, Boatswain, Navigator, Cook, probably, although maybe someone else is in the cook's place.
There are only four of us left! Everyone, except the captain, watches one innocent person (i.e., the captain himself) and two others, meaning they only vote for one of the two.
For me, it's Slonysh and Vegtam. It's easy to kill: Hermit gives a vote, and someone else gives a vote.
Slonysh seemed to be very suspicious at the beginning of the game, but then she became calmer, I think. Veg is generally quiet. It's hard to choose)
So, the cards. Who could they be pointing to? I'll check the profiles now and try to figure something out.

Aaa, a huge fail. After the navigator's death, the ship only gets caught in a storm the following night. So yes, Zedzi was the navigator.
