Can you help me at understanding this sentence?
Da kommt sein Schiff an eine kleine Insel.
I know that da means there. I've looked it up in several dictionaries.
Google Translate, for instance, helped me a lot, suggesting the meaning of sein (i.e. his), but it also suggests that da means as.
I know that one meaning of sein is to be, but I could find that it is also used as a possessive pronoun.
So, I'm a little confused about da and sein in the sentence above. Could you help me clarify the intended meaning?
