Thank you. I still have a few doubts.
So both sentences are correct:
1) " the ship was caught in a violent storm, then by mist and snow" OR
"the mariners were struck by a violent storm .."
2) The sun rose on the left out of the sea, shone bright over the mast at noon and finally went down into the sea.
1) I'd write this: The ship was struck by a violent storm and then overtaken by mist and snow.
2) The sun rose on the ship's left, shone bright over the mast at noon, and finally went down at the ship's right into the sea.
(The poet is using "left" and "right" to indicate east and west.)
