I just want to be sure that I got the tenses right in the following summary.

As you told me, I used the simple present. I just wanted to know if the sentences in the past are correct.Thank you.

1) Once the narrator boarded (?) a ship bound for the Archipelago Islands. 2) One evening he observes a strange, isolated cloud to the North-West. After a while, he notices it has spread (?) westward and eastward, forming a narrow strip of vapour above the horizon.
3) He notices the red of the room, the transparency of the sea water, the intolerable heat, and the absolute calm when the wind stopped (?) blowing.
4) The captain decides to sail, despite the narrator’s fears.
5) All of a sudden, the sea grows angry, and big waves overtake the ship. Luckily, the ship lifts from the sea and regains her right position. He is surprised to see the foaming ocean around him.
6) He soon discovers that he is only (?) one of two survivors of the shipwreck. The other survivor is a Swede, who shipped with them just as they left port. All the other members of the crew die and are swept out to sea.
